Introduction: Why PaleoHacks Keto One Pan Cookbook Matters in 2025
The keto diet remains one of the most popular nutrition strategies in 2025. Millions of men and women still use low-carb, high-fat meals to reach weight goals, improve energy, and simplify their eating habits. But one challenge has always stood out: keto meals often feel time-consuming, complicated, and hard to clean up after.
That’s where the PaleoHacks Keto One Pan Cookbook comes in. This cookbook is a treasure trove of quick-prep, easy-to-clean recipes that need only one pan or pot. From soups and casseroles to salmon, chicken, and a wide range of vegetarian options, the recipes are designed to excite beginners and experienced keto followers alike.
With dinner often being the most stressful meal of the day, the cookbook provides a realistic solution for busy households. You’ll find meals that take 15 minutes or less to prepare, taste delicious, and support keto goals without long hours in the kitchen, saving you precious time and effort.
What Is PaleoHacks Keto One Pan Cookbook and How Does It Work for Weight Loss?
The PaleoHacks Keto One Pan Cookbook is a full-color recipe book designed for anyone who wants to enjoy keto-friendly meals without the stress of long prep times or messy cleanups. Inside, you’ll find 70 recipes that keep net carbs low, flavors high, and preparation simple. These recipes include a variety of dishes such as [dish 1], [dish 2], and [dish 3]. Each dish is built around one rule: everything is cooked in a single pan, pot, or skillet.
This approach works because it removes the main barriers that stop people from sticking to keto. Instead of juggling multiple pots and pans or complicated ingredients, you spend less time cooking and cleaning. Most meals take 15 minutes or less to prep, allowing you to relax while your dinner finishes in the oven or on the stove, and making the most of your time.
Beyond convenience, the recipes are designed to support a keto lifestyle by keeping carb counts under control. Many recipes feature under 10 grams of net carbs, making it easier to maintain ketosis. Whether you are new to keto or looking for fresh recipe ideas, this cookbook provides a structure that works in real life, giving you the confidence to stick to your keto journey.
Best Keto Cookbook Options and Keto One Pan Benefits in 2025

Health professionals often note that success with keto depends less on willpower and more on access to practical recipes. A structured cookbook, such as PaleoHacks Keto One Pan, reduces decision fatigue and ensures meals meet the macronutrient balance needed for ketosis. For many beginners, this eliminates the trial-and-error that leads to frustration and diet dropouts, instilling a sense of confidence in their diet journey.

The PaleoHacks Keto One Pan Cookbook stands apart because it targets the biggest pain points most people face: limited time, messy kitchens, and lack of variety.
Here’s what some of our users have to say about the PaleoHacks Keto One Pan Cookbook:
Many competitors require longer prep times, while PaleoHacks keeps prep under 15 minutes, thanks to our convenient one-pan recipes.Some cookbooks rely heavily on specialty ingredients, while this one uses items you can find in most grocery stores.
A number of guides focus on either weight loss or taste, but PaleoHacks Keto One Pan Cookbook strikes a perfect balance, ensuring you feel both satisfied and healthy. Other one-pan cookbooks often skip detailed nutrition info, while this book includes serving sizes and macros for each recipe.
While apps and online blogs may offer quick inspiration, they rarely provide the structured meal consistency that a physical cookbook delivers. With PaleoHacks Keto One Pan Cookbook, you receive a tested, organized guide that helps sustain keto long term, making you feel secure and committed to your health journey.
Safety, Risks, and Responsible Use of Keto Cookbooks
When embarking on any nutrition plan, it’s crucial to maintain a sense of balance and awareness. While the keto diet has shown significant benefits for many, it’s not a one-size-fits-all solution. Before diving into the world of keto or trying out recipes from the PaleoHacks Keto One Pan Cookbook, it’s imperative to seek advice from a qualified healthcare provider, particularly if you have existing medical conditions or are taking prescribed medication.
Potential risks of keto include digestive changes, fatigue during the adjustment phase, or nutrient imbalances if meals are not varied. A cookbook can reduce these risks by offering structured recipes with vegetables, healthy fats, and proteins. However, it’s crucial to remember that professional guidance is still the best way to ensure your safety and well-being.
Responsible use of the cookbook also involves understanding that individual results may vary. While success stories abound, the average outcomes are usually modest unless the keto diet is part of an overall healthy lifestyle. The cookbook is a valuable tool for simplifying meal preparation, reducing kitchen stress, and promoting long-term consistency. However, it should never be seen as a replacement for medical treatment or advice.

Ketogenic diets are put to the test for diabetes reversal.
As you can see at the start of my video Does a Ketogenic Diet Help Diabetes or Make It Worse?, ketogenic diets can lower blood sugars better than conventional diets. So much so, in fact, that there is a keto product company that claims ketogenic diets can “reverse” diabetes. However, they are confusing the symptom (high blood sugars) with the disease (carbohydrate intolerance). People with diabetes can’t properly handle carbohydrates, and this manifests as high blood sugars. Clearly, if you stick to eating mostly fat, your blood sugars will stay low, but you may be actually making the underlying disease worse at the same time.
We’ve known for nearly a century that if you put people on a ketogenic diet, their carbohydrate intolerance can skyrocket within just two days. Below and at 0:46 in my video, you can see a graph from the study showing the blood sugar response two days after eating sugar. On a high-carb diet, blood sugar response is about 90 mg/dL. But, the blood sugar response to the same amount of sugar after a high-fat diet is about 190 mg/dL, nearly double. The intolerance to carbohydrates skyrocketed on a high-fat diet.
After one week on an 80 percent fat diet, you can quintuple your blood sugar spike in reaction to the same carb load compared to a week on a low-fat diet, as you can see in the graph below and at 1:12 in my video.
Even a single day of excessive dietary fat intake can do it, as you can see in the graph below and at 1:26 in my video. If you’re going in for a diabetes test, having a fatty dinner the night before can adversely affect your results. Just one meal high in saturated fat can make carbohydrate intolerance, the cause of diabetes, worse within four hours.
Given enough weight loss by any means, whether from cholera or bariatric surgery, type 2 diabetes can be reversed, but a keto diet for diabetes may not just be papering over the cracks, but actively throwing fuel on the fire.
I’ve been trying to think of a good metaphor. It’s easy to come up with things that just treat the symptoms without helping the underlying disease, like giving someone with pneumonia aspirin for their fever instead of antibiotics. However, a keto diet for diabetes is worse than that because it may treat the symptoms while actively worsening the disease. It may be more like curing the fever by throwing that pneumonia patient out into a snow bank or “curing” your amputated finger by amputating your hand. One of the co-founders of masteringdiabetes.org suggested it’s like a CEO who makes their bad bottom line look better by borrowing tons of cash. The outward numbers look better, but on the inside, the company is just digging itself into a bigger hole.
Do you remember The Club, that popular car anti-theft device that attaches to the steering wheel and locks it in place so the steering column can only turn a few inches? Imagine you’re in a car at the top of a hill with the steering wheel locked. Then, the car starts rolling down the hill. What do you do? Imagine there’s also something stuck under your brake pedal. The keto-diet equivalent response to this situation is who cares if you’re barreling down into traffic with a locked steering wheel and no brakes—just stick to really straight deserted roads without any stop signs or traffic lights. If you do that, problem solved! The longer you go, the more speed you’ll pick up. If you should hit a dietary bump in the road or start to veer off the path, the consequences could get more and more disastrous over time. However, if you stick to the keto straight and narrow, you’ll be a-okay! In contrast, the non-keto response would be to just unlock the steering wheel and dislodge whatever’s under your brake. In other words, fix the underlying problem instead of just whistling past—and then into—the graveyard.
The reason keto proponents claim they can “reverse” diabetes is they can successfully wean type 2 diabetics off their insulin. That’s like faith-healing someone out of the need for a wheelchair by making them stay in bed the rest of their life. No need for a wheelchair if you never move. Their carbohydrate intolerance isn’t gone. Their diabetes isn’t gone. In fact, it could be just as bad or even worse. Type 2 diabetes is reversed when you are weaned off insulin while eating a normal diet like everyone else. Then and only then do you not have diabetes anymore. A true diabetes reversal diet, as you can see below and at 4:58 in my video, is practically the opposite of a ketogenic diet: getting diabetics off their insulin within a matter of weeks by eating more than 300 grams of carbs a day! The irony doesn’t stop there. One of the reasons people with diabetes suffer such nerve and artery damage is due to an inflammatory metabolic toxin known as methylglyoxal, which forms at high blood sugar levels. Methylglyoxal is the most potent creator of advanced glycation end products (AGEs), which are implicated in degenerative diseases—from Alzheimer’s and cataracts to kidney disease and strokes, as you can see below and at 5:31 in my video.
You get AGEs in your body from two sources: You can eat them preformed in your diet or make them internally from methylglyoxal if you have high blood sugar levels. On a keto diet, one would expect high exposure to preformed AGEs, since they’re found concentrated in animal-derived foods high in fat and protein, but we would expect less internal, new formation due to presumably low levels of methylglyoxal, given lower blood sugars from not eating carbs. Dartmouth researchers were surprised to find more methylglyoxal! As shown in the graph below and at 6:11 in my video, a few weeks on the Atkins diet led to a significant increase in methylglyoxal levels. Those in active ketosis did even worse, doubling the level of this glycotoxin in their bloodstream.
It turns out that high sugars may not be the only way to create this toxin, as you can see below and at 6:24 in my video. One of the ketones you make on a ketogenic diet is acetone (known for its starring role in nail polish remover). Acetone does more than just make keto dieters fail breathalyzer tests, “feel queasy and light-headed, and develop what’s been described as ‘rotten apple breath.’” Acetone can oxidize in the blood to form acetol, which may be a precursor for methylglyoxal.
That may be why keto dieters can end up with levels of this glycotoxin as high as those with out-of-control diabetes, which can cause the nerve damage and blood vessel damage you see in diabetics. That’s another way keto dieters can end up with a heart attack. The irony of treating diabetes with a ketogenic diet may extend beyond just making the underlying diabetes worse, but by mimicking some of the disease’s dire consequences.
This is part of a seven-video series on keto, which you can find in related videos below.
Ketogenic diets have been found to undermine exercise efforts and lead to muscle shrinkage and bone loss.
An official International Society of Sports Nutrition position paper covering keto diets notes the “ergolytic effect” of keto diets on both high- and low-intensity workouts. Ergolytic is the opposite of ergogenic. Ergogenic means performance-boosting, whereas ergolytic means performance-impairing.
For nonathletes, ketosis may also undermine exercise efforts. Ketosis was correlated with increased feelings of “perceived exercise effort” and “also significantly correlated to feelings of ‘fatigue’ and to ‘total mood disturbance,’” during physical activity. “Together, these data suggest that the ability and desire to maintain sustained exercise might be adversely impacted in individuals adhering to ketogenic diets for weight loss.”
You may recall that I’ve previously discussed that shrinkage of measured muscle mass among CrossFit trainees has been reported. So, a ketogenic diet may not just blunt the performance of endurance athletes, but their strength training as well. As I discuss in my video Keto Diets: Muscle Growth and Bone Density, study participants performed eight weeks of the battery of standard upper and lower body training protocols, like bench presses, pull-ups, squats, and deadlifts, and there was no surprise. You boost muscle mass—unless you’re on a keto diet, in which case there was no significant change in muscle mass after all that effort. Those randomized to a non-ketogenic diet added about three pounds of muscle mass, whereas the same amount of weight lifting on the keto diet tended to subtract muscle mass by about 3.5 ounces on average. How else could you do eight weeks of weight training and not gain a single ounce of muscle on a ketogenic diet? Even keto diet advocates call bodybuilding on a ketogenic diet an “oxymoron.”
What about bone loss? Sadly, bone fractures are one of the side effects that disproportionately plague children placed on ketogenic diets, along with slowed growth and kidney stones. Ketogenic diets may cause a steady rate of bone loss as measured in the spine, presumed to be because ketones are acidic, so keto diets can put people in what’s called a “chronic acidotic state.”
Some of the case reports of children on keto diets are truly heart-wrenching. One nine-year-old girl seemed to get it all, including osteoporosis, bone fractures, and kidney stones, then she got pancreatitis and died. Pancreatitis can be triggered by having too much fat in your blood. As you can see in the graph below and at 2:48 in my video, a single high-fat meal can cause a quintupling of the spike in triglycerides in your bloodstream within hours of consumption, which can put you at risk for inflammation of the pancreas.
The young girl had a rare genetic disorder called glucose transporter deficiency syndrome. She was born with a defect in ferrying blood sugar into her brain. That can result in daily seizures starting in infancy, but a ketogenic diet can be used as a way to sneak fuel into the brain, which makes a keto diet a godsend for the 1 in 90,000 families stricken with this disorder.
As with anything in medicine, it’s all about risks versus benefits. As many as 30 percent of patients with epilepsy don’t respond to anti-seizure drugs. Unfortunately, the alternatives aren’t pretty and can include brain surgery that implants deep electrodes through the skull or even removes a lobe of your brain. This can obviously lead to serious side effects, but so can having seizures every day. If a ketogenic diet can help with seizures, the pros can far outweigh the cons. For those just choosing a diet to lose weight, though, the cost-benefit analysis would really seem to go the other way. Thankfully, you don’t need to mortgage your long-term health for short-term weight loss. We can get the best of both worlds by choosing a healthy diet, as I discussed in my video Flashback Friday: The Weight Loss Program That Got Better with Time.
Remember the study that showed the weight loss was nearly identical in those who had been told to eat the low-carb Atkins diet for a year and those told to eat the low-fat Ornish diet, as seen below and at 4:18 in my video? The authors concluded, “This supports the practice of recommending any diet that a patient will adhere to in order to lose weight.” That seems like terrible advice.
There are regimens out there like “The Last Chance Diet which consisted of a low-calorie liquid formula made from leftover byproducts from a slaughterhouse [that] was linked to approximately 60 deaths from cardiovascular-related events.” An ensuing failed lawsuit from one widower laid the precedent for the First Amendment protection for those who produce deadly diet books.
It’s possible to construct a healthy low-carb diet or an unhealthy low-fat one—a diet of cotton candy would be zero fat—but the health effects of a typical low-carb ketogenic diet like Atkins are vastly different from a low-fat plant-based diet like Ornish’s. As you can see in the graph below and at 5:26 in my video, they would have diametrically opposed effects on cardiovascular risk factors in theory, based on the fiber, saturated fat, and cholesterol contents of their representative meal plans.
And when actually put to the test, low-carb diets were found to impair artery function. Over time, blood flow to the heart muscle itself is improved on an Ornish-style diet and diminished on a low-carb one, as shown below and at 5:44 in my video. Heart disease tends to progress on typical weight-loss diets and actively worsens on low-carb diets, but it may be reversed by an Ornish-style diet. Given that heart disease is the number one killer of men and women, “recommending any diet that a patient will adhere to in order to lose weight” seems irresponsible. Why not tell people to smoke? Cigarettes can cause weight loss, too, as can tuberculosis and a meth habit. The goal of weight loss is not to lighten the load for your pallbearers.

What are the effects of ketogenic diets on nutrient sufficiency, gut flora, and heart disease risk?
Given the decades of experience using ketogenic diets to treat certain cases of pediatric epilepsy, a body of safety data has accumulated. Nutrient deficiencies would seem to be the obvious issue. Inadequate intake of 17 micronutrients, vitamins, and minerals has been documented in those on strict ketogenic diets, as you can see in the graph below and at 0:14 in my video Are Keto Diets Safe?.
Dieting is a particularly important time to make sure you’re meeting all of your essential nutrient requirements, since you may be taking in less food. Ketogenic diets tend to be so nutritionally vacuous that one assessment estimated that you’d have to eat more than 37,000 calories a day to get a sufficient daily intake of all essential vitamins and minerals, as you can see in the graph below and at 0:39 in my video.
That is one of the advantages of more plant-based approaches. As the editor-in-chief of the Journal of the American Dietetic Association put it, “What could be more nutrient-dense than a vegetarian diet?” Choosing a healthy diet may be easier than eating more than 37,000 daily calories, which is like putting 50 sticks of butter in your morning coffee.
We aren’t just talking about not reaching your daily allowances either. Children have gotten scurvy on ketogenic diets, and some have even died from selenium deficiency, which can cause sudden cardiac death. The vitamin and mineral deficiencies can be solved with supplements, but what about the paucity of prebiotics, the dozens of types of fiber, and resistant starches found concentrated in whole grains and beans that you’d miss out on?
Not surprisingly, constipation is very common on keto diets. As I’ve reviewed before, starving our microbial self of prebiotics can have a whole array of negative consequences. Ketogenic diets have been shown to “reduce the species richness and diversity of intestinal microbiota,” our gut flora. Microbiome changes can be detected within 24 hours of switching to a high-fat, low-fiber diet. A lack of fiber starves our good gut bacteria. We used to think that dietary fat itself was nearly all absorbed in the small intestine, but based on studies using radioactive tracers, we now know that about 7 percent of the saturated fat in a fat-rich meal can make it down to the colon. This may result in “detrimental changes” in our gut microbiome, as well as weight gain, increased leaky gut, and pro-inflammatory changes. For example, there may be a drop in beneficial Bifidobacteria and a decrease in overall short-chain fatty acid production, both of which would be expected to increase the risk of gastrointestinal disorders.
Striking at the heart of the matter, what might all of that saturated fat be doing to our heart? If you look at low-carbohydrate diets and all-cause mortality, those who eat lower-carb diets suffer “a significantly higher risk of all-cause mortality,” meaning they live, on average, significantly shorter lives. However, from a heart-disease perspective, it matters if it’s animal fat or plant fat. Based on the famous Harvard cohorts, eating more of an animal-based, low-carb diet was associated with higher death rates from cardiovascular disease and a 50 percent higher risk of dying from a heart attack or stroke, but no such association was found for lower-carb diets based on plant sources.
And it wasn’t just Harvard. Other researchers have also found that “low-carbohydrate dietary patterns favoring animal-derived protein and fat sources, from sources such as lamb, beef, pork, and chicken, were associated with higher mortality, whereas those that favored plant-derived protein and fat intake, from sources such as vegetables, nuts, peanut butter, and whole-grain bread, were associated with lower mortality…”
Cholesterol production in the body is directly correlated to body weight, as you can see in the graph below and at 3:50 in my video.
Every pound of weight loss by nearly any means is associated with about a one-point drop in cholesterol levels in the blood. But if we put people on very-low-carb ketogenic diets, the beneficial effect on LDL bad cholesterol is blunted or even completely neutralized. Counterbalancing changes in LDL or HDL (what we used to think of as good cholesterol) are not considered sufficient to offset this risk. You don’t have to wait until cholesterol builds up in your arteries to have adverse effects either; within three hours of eating a meal high in saturated fat, you can see a significant impairment of artery function. Even with a dozen pounds of weight loss, artery function worsens on a ketogenic diet instead of getting better, which appears to be the case with low-carb diets in general.

Might the appetite-suppressing effects of ketosis improve dietary compliance?
The new data are said to debunk “some, if not all, of the popular claims made for extreme carbohydrate restriction,” but what about ketones suppressing hunger? In a tightly controlled metabolic ward study where the ketogenic diet made things worse, everyone ate the same number of calories, but those on a keto diet lost less body fat. But, out in the real world, all of those ketones might spoil your appetite enough that you’d end up eating significantly less overall. On a low-carb diet, people end up storing 300 more calories of fat every day. Outside of the laboratory, though, if you were in a state of ketosis, might you be able to offset that if you were able to sustainably eat significantly less?
Paradoxically, as I discuss in my video Is Weight Loss on Ketosis Sustainable?, people may experience less hunger on a total fast compared to an extremely low-calorie diet. This may be thanks to ketones. In this state of ketosis, when you have high levels of ketones in your bloodstream, your hunger is dampened. How do we know it’s the ketones? If you inject ketones straight into people’s veins, even those who are not fasting lose their appetite, sometimes even to the point of getting nauseated and vomiting. So, ketones can explain why you might feel hungrier after a few days on a low-calorie diet than on a total zero-calorie diet—that is, a fast.
Can we then exploit the appetite-suppressing effects of ketosis by eating a ketogenic diet? If you ate so few carbs to sustain brain function, couldn’t you trick your body into thinking you’re fasting and get your liver to start pumping out ketones? Yes, but is it safe? Is it effective?
As you can see below and at 1:58 in my video, a meta-analysis of 48 randomized trials of various branded diets found that those advised to eat low-carb diets and those told to eat low-fat ones lost nearly identical amounts of weight after a year.
Obviously, high attrition rates and poor dietary adherence complicate comparisons of efficacy. The study participants weren’t actually put on those diets; they were just told to eat in those ways. Nevertheless, you can see how even just moving in each respective direction can get rid of a lot of CRAP (which is Jeff Novick’s acronym for Calorie-Rich And Processed foods). After all, as you can see in the graph below and at 2:37 in my video, the four largest calorie contributors in the American diet are refined grains, added fats, meat, and added sugars.
Low-carb diets cut down on refined grains and added sugars, and low-fat diets tend to cut down on added fats and meat, so they both tell people to cut down on donuts. Any diet that does that already has a leg up. I figure a don’t-eat-anything-that-starts-with-the-letter-D diet could also successfully cause weight loss if it caused people to cut down on donuts, danishes, and Doritos, even if it makes no nutritional sense to exclude something like dill.
The secret to long-term weight-loss success on any diet is compliance. Diet adherence is difficult, though, because any time you try to cut calories, your body ramps up your appetite to try to compensate. This is why traditional weight-loss approaches, like portion control, tend to fail. For long-term success, measured not in weeks or months but in years and decades, this day-to-day hunger problem must be overcome. On a wholesome plant-based diet, this can be accomplished thanks in part to calorie density because you’re just eating so much food. On a ketogenic diet, it may be accomplished with ketosis. In a systematic review and meta-analysis entitled “Do Ketogenic Diets Really Suppress Appetite,” researchers found that the answer was yes. Ketogenic diets also offer the unique advantage of being able to track dietary compliance in real-time with ketone test strips you can pee on to see if you’re still in ketosis. There’s no pee stick that will tell you if you’re eating enough fruits and veggies. All you have is the bathroom scale.
Keto compliance may be more in theory than practice, though. Even in studies where ketogenic diets are being used to control seizures, dietary compliance may drop below 50 percent after a few months. This can be tragic for those with intractable epilepsy, but for everyone else, the difficulty in sticking long-term to ketogenic diets may actually be a lifesaver. I’ll talk about keto diet safety next.
The keto diet is in contrast to a diet that would actually be healthful to stick to. See, for example, my video series on the CHIP program here.
This was the fourth video in a seven-part series on keto diets. If you haven’t yet, be sure to watch the others listed in the related videos below.
Let’s dive into ketogenic diets and their $33-billion gimmick.
The carbohydrate–insulin model of obesity, the underlying theory that ketogenic diets have some sort of metabolic advantage, has been experimentally falsified. Keto diet proponents’ own studies showed the exact opposite: Ketogenic diets actually put you at a metabolic disadvantage and slow the loss of body fat. How much does fat loss slow down on a low-carb diet?
As I discuss in my video Keto Diet Results for Weight Loss, if you cut about 800 calories of carbohydrates from your diet a day, you lose 53 grams of body fat a day. But if you cut the same number of fat calories, you lose 89 grams of fat a day. Same number of calories cut, but nine butter pats’ worth of extra fat melting off your body each day on a low-fat diet, compared to a low-carb one. Same number of calories, but about 80 percent more fat loss when you cut down on fat instead of carbs. You can see a graph of these results below and at 1:07 in my video. The title of the study speaks for itself: “Calorie for Calorie, Dietary Fat Restriction Results in More Body Fat Loss Than Carbohydrate Restriction in People with Obesity.”
Just looking at the bathroom scale, though, would mislead you into thinking the opposite. After six days on the low-carb diet, study subjects lost four pounds. On the low-fat diet, they lost less than three pounds, as you can see in the graph below and at 1:40 in my video. So, according to the scale, it looked like the low-carb diet wins hands down. You can see why low-carb diets are so popular. What was happening inside their bodies, however, tells the real story. The low-carb group was losing mostly lean mass—water and protein. This loss of water weight helps explain why low-carb diets have “been such a persistent theme for authors of diet books and such ‘cash cows’ for publishers,” going back more than the last 150 years. That’s their secret. As one weight-loss expert noted, “Rapid water loss is the $33-billion diet gimmick.”
When you eat carbohydrates, your body bulks up your muscles with glycogen for quick energy. Eat a high-carbohydrate diet for three days, and you may add about three pounds of muscle mass onto your arms and legs, as you can see below and at 2:34 in my video. Those glycogen stores drain away on a low-carb diet and pull water out with it. (The ketones also need to be flushed out of the kidneys, pulling out even more water.) On the scale, that can manifest as four more pounds coming off within ten days, but that “was all accounted for by losses in total body water”—that is water loss.
The bottom line: Keto diets just don’t hold water.
The thrill of seeing the pounds come off so quickly on the scale keeps many coming back to the low-carb altar. When the diet fails, the dieters often blame themselves, but the intoxication of that initial, rapid weight loss may tempt them back, like getting drunk again after forgetting how terrible the last hangover was. This has been dubbed the “false hope syndrome.” “The diet industry thrives for two reasons—big promises and repeat customers,” something low-carb diets were built for, given that initial, rapid water loss.
What we care about is body fat. In six days, the low-fat diet extracted a total of 80 percent more fat from the body than the low-carb diet. It’s not just one study either. As you can see below and at 3:54 in my video, you can look at all of the controlled feeding trials where researchers compared low-carb diets to low-fat ones, swapping the same number of carb calories for fat calories or vice versa. If a calorie is just a calorie, then all of the studies should have crossed that zero line in the middle, straddling “favors low-fat diet” and “favors low-carb diet,” and indeed six did. One study showed more fat loss on a low-carb diet, but every other study favored the low-fat diet—more loss of body fat eating the same number of calories. When you put all of the studies together, we’re talking 16 more grams of daily body fat lost on the low-fat diets. That’s like four more pats of butter melting off your body on a daily basis. Less fat in the mouth means less fat on the hips, even when you’re taking in the same number of calories.
This is the third installment of my seven-part series on keto diets.
This keto research came from the deep dive I took for my book How Not to Diet. (All proceeds I receive from my books are donated to charity.) You can learn more about How Not to Diet and order it here. Also please feel free to check out some of my popular weight-loss videos in related videos below.
Do low-carb and ketogenic diets have a metabolic advantage for weight loss?
When you don’t eat enough carbohydrates, you force your body to burn more fat. “However, this rise in fat oxidation [burning] is often misconstrued as a greater rate of net FM [fat-mass] reduction” in the body, ignoring the fact that, on a ketogenic diet, your fat intake shoots up, too. What happens to your overall body fat balance? You can’t empty a tub by widening the drain if you’re opening the faucet at the same time. Low-carb advocates had a theory, though, the “carbohydrate–insulin model of obesity,” which I discuss in my video Keto Diet Theory Put to the Test.
Proponents of low-carb diets, whether a ketogenic diet or a more relaxed form of carbohydrate restriction, suggested that decreased insulin secretion would lead to less fat storage, so even if you were eating more fat, less of it would stick to your frame. We’d burn more and store less, the perfect combination for fat loss—or so the theory went. To their credit, instead of just speculating about it, they decided to put it to the test.
Gary Taubes formed the Nutrition Science Initiative (NuSI) to sponsor research to validate the carbohydrate–insulin model. He’s the journalist who wrote the controversial 2002 New York Times Magazine article “What If It’s All Been a Big Fat Lie?” which attempted to turn nutrition dogma on its head by arguing in favor of the Atkins diet with its bunless bacon cheeseburgers based on the carbohydrate–insulin model. (Much of Nina Teicholz’s book The Big Fat Surprise is simply recycled from Taubes’ earlier work.)
In response, some of the very researchers Taubes cited to support his thesis accused him of twisting their words. One said, “The article was incredibly misleading…I was horrified.” Said another, “He took this weird little idea and blew it up, and people believed him…What a disaster.” It doesn’t matter what people say, though. All that matters is the science.
Taubes attracted $40 million in committed funding for his Nutrition Science Initiative to prove to the world that you could lose more body fat on a ketogenic diet. NuSI contracted noted researcher Kevin Hall from the National Institutes of Health to perform the study. Seventeen overweight or obese men were effectively locked in what’s called a metabolic ward for two months to allow researchers total control over their diets. For the first month, they were placed on a typical high-carbohydrate diet (50 percent carbs, 35 percent fat, 15 percent protein), then were switched to a low-carb ketogenic diet (only 5 percent of calories from carbohydrates and 80 percent fat) for the second month. Both diets had the same number of daily calories. So, if a calorie is a calorie when it comes to weight loss, there should be no difference in body fat loss on the regular diet versus the ketogenic diet. If Taubes was right, though, if fat calories were somehow less fattening, then body fat loss would become accelerated on a keto diet. Instead, in the very study funded by the Nutrition Science Initiative, researchers found that body fat loss slowed during the ketogenic diet.
Why do people think the keto diet works if it actually slows fat loss? Well, as you can see in the graph below and at 3:40 in my video, if you looked only at the readings on bathroom scales, the ketogenic diet would seem like a smashing success. Participants went from losing less than a pound a week on the regular diet during the first two weeks of the study to losing three and a half pounds within seven days after switching to the ketogenic diet. What was happening inside their bodies, however, told a totally different story: Their rate of body fat loss was slowed by more than half. So, most of what they were losing was just water weight. It’s presumed the reason they started burning less fat on a ketogenic diet was because, without the preferred fuel of carbohydrates, their bodies started burning more of their own protein—and that’s exactly what happened. Switching to a ketogenic diet made them lose less fat mass and more fat-free mass. Indeed, they lost more lean mass. That may help explain why the leg muscles of CrossFit trainees placed on a ketogenic diet may shrink as much as 8 percent. The vast lateralis, the biggest quad muscle in your leg, shrunk in thickness by 8 percent on a ketogenic diet.
Yes, the study subjects started burning more fat on the ketogenic diet, but they were also eating so much more fat on the keto diet that they ended up retaining more fat in their body, despite the lower insulin levels. This is “diametrically opposite” to what the keto crowd predicted, and this is from the guy Nutrition Science Initiative paid to support its theory. In science-speak, “the carbohydrate–insulin model failed experimental interrogation.”
In light of this “experimental falsification” of the low-carb theory, the Nutrition Science Initiative effectively collapsed but, based on its tax returns, not before Taubes and his co-founder personally pocketed millions of dollars in compensation.
This is the second installment in my seven-part series on keto diets. In case you missed them, check out the other related videos below.
The more things change, the more they stay the same. I created a whole website about the Atkins Diet, but, sadly, people keep falling into the low-carb trap. You can find some of my older videos on low-carb diets listed below.
What does the science say about the clinical use of ketogenic diets for epilepsy and cancer?
Blood sugar, alsoknown as blood glucose, is the universal go-to fuel for the cells throughout our bodies. Our brain burns through a quarter pound of sugar a day because “glucose is the preferred metabolic fuel.” We can break down proteins and make glucose from scratch, but most comes from our diet in the form of sugars and starches. If we stop eating carbohydrates (or stop eating altogether), most of our cells switch over to burning fat. Fat has difficulty getting through the blood-brain barrier, though, and our brain has a constant, massive need for fuel. Just that one organ accounts for up to half of our energy needs. Without it, the lights go out…permanently.
Tomake that much sugar from scratch, our body would need to break down about half a pound of protein a day. That means we’d cannibalize ourselves to death within two weeks, but people can fast for months. What’s going on? The answer to the puzzle wasdiscovered in 1967. Harvard researchers famously stuck catheters into the brains of obese subjects who had been fasting for more than a month and discovered that ketones had replaced glucose as the preferred fuel for the brain. Our liver can turn fat into ketones, which can then breach the blood-brain barrier and sustain our brain if we aren’t getting enough carbohydrates. Switching fuels has such an effect on brain activity that it has been used to treat epilepsy since antiquity.
In fact, the prescription of fasting for the treatment of epileptic seizures dates back to Hippocrates. In the Bible, even Jesus seems to have concurred. To this day, it’s unclear whyswitching from blood sugar to ketones as a primary fuel source has such a dampening effect on brain overactivity. How long can one fast? To prolong the fasting therapy, in 1921, a distinguished physician scientist at the Mayo Clinicsuggested trying what he called “ketogenic diets,” high-fat diets designed to be so deficient in carbohydrates that they could effectively mimic the fasting state. “Remarkable improvement” wasnoted the first time it was put to the test, efficacy that was later confirmed in randomized, controlled trials. Ketogenic diets started to fall out of favor in 1938 with the discovery of the anti-seizure drug that would become known as Dilantin, but they’re still being used today as a third- or fourth-line treatment for drug-refractory epilepsy in children.
Oddly, the success of ketogenic diets against pediatric epilepsy seems to get conflated by “keto diet” proponents into suggesting a ketogenic diet is beneficial for everyone. Know what else sometimes works for intractable epilepsy? Brain surgery, but I don’t hear people clamoring to get their skulls sawed open. Since when do medical therapies translate into healthy lifestyle choices? Scrambling brain activity with electroshock therapy can be helpful in some cases of major depression, so should we get out the electrodes? Ketogenic diets are also being tested to see if they can slow the growth of certain brain tumors. Even if they work, you know what else can help slow cancer growth? Chemotherapy. So why go keto when you can just go chemo?
Promoters of ketogenic diets for cancer are paid by so-called ketone technology companies that offer to send you salted caramel bone broth powder for a hundred bucks a pound or companies that market ketogenic meals and report “extraordinary” anecdotal responses in some cancer patients. But more concrete evidence is simply lacking, and even the theoretical underpinnings may be questionable. A common refrain is that “cancer feeds on sugar.” But all cells feed on sugar. Advocating ketogenic diets for cancer is like saying Hitler breathed air so we should boycott oxygen.
Cancer can feed on ketones, too. Ketones have been found to fuel human breast cancer growth and drive metastases in an experimental model, more than doubling tumor growth. Some have even speculated that this may be why breast cancer often metastasizes to the liver, the main site of ketone production. As you can see below and at 4:59 in my video Is Keto an Effective Cancer-Fighting Diet?, if you drip ketones directly onto breast cancer cells in a petri dish, the genes that get turned on and off make for much more aggressive cancer, associated with significantly lower five-year survival in breast cancer patients, as you can see in the following graph and at 5:05 in my video. Researchers are even considering designing ketone-blocking drugs to prevent further cancer growth by halting ketone production.
Let’s also think about what eating a ketogenic diet might entail. High animal fat intake may increase the mortality risk among breast cancer survivors and potentially play a role in the development of breast cancer in the first place through oxidative stress, hormone disruption, or inflammation. This applies to men, too. “A strong association” has been found “between saturated fat intake and prostate cancer progression and survival.” Those in the top third of consumption of these kinds of fat-rich animal foods appeared to triple their risk of dying from prostate cancer. This isn’t necessarily fat in general either. No difference has been found in breast cancer death rates based on total fat intake. However saturated fat intake specifically may negatively impact breast cancer survival, increasing the risk of dying from it by 50 percent. There’s a reason the official American Cancer Society and American Society of Clinical Oncology Breast Cancer Survivorship Care Guideline recommend a dietary pattern for breast cancer patients that’s essentially the opposite of a ketogenic diet. It calls for a diet that’s “high in vegetables, fruits, whole grains, and legumes [beans, split peas, chickpeas, and lentils]; low in saturated fats; and limited in alcohol consumption.”
“To date, not a single clinical study has shown a measurable benefit from a ketogenic diet in any human cancer.” There are currently at least a dozen trials underway, however, and the hope is that at least some cancer types will respond. Still, even then, that wouldn’t serve as a basis for recommending ketogenic diets for the general population any more than recommending everyone get radiation, surgery, and chemo just for kicks.
“Keto” has been the most-searched keyword on NutritionFacts.org for months, and I didn’t have much specific to offer…until now.Check out my other videos on the topic in related videos below.
If you have questions about the Keto Diet, well my friend, you’ve come to the right place!
We help our coaching clients completely overhaul their nutrition, including going low-carb, and today we’ll give you everything you need to start a Ketogenic Diet.
We’ve learned a lot by helping people begin the Keto Diet: there’s plenty of good, there’s plenty of bad, and there’s plenty of ugly.
Today, we share with you what we’ve discovered.
Here’s what we’ll cover in our GINORMOUS Guide to the Keto Diet (click to skip to that section):
Whew. It’s a lot to cover. Even just typing out the Table of Contents was exhausting.
But hang in there!
You’ll learn how to do Keto right, plus I’ll share cute animal gifs to make sure you’re still paying attention, like this one:
If you don’t have a lot of time, but do want an exact plan to follow, I got you. Since this is a MASSIVE article (the longest published on Nerd Fitness!), if you’d rather read it in a snazzy digital guide form, you can download our Beginner’s Guide to the Keto Dietfree when you sign up in the box below:
The Ketogenic diet, or Keto diet, is a food strategy in which you drastically reduce your carbohydrate intake and replace it with fat in order to get your metabolism to a state called ketosis.
In ketosis, your body converts fat to fuel to burn for energy like Tony Stark burns Captain America for being uptight.
Don’t worry, the jokes will only get worse from here.
When you’re in ketosis, your body is burning fat for fuel, and this can help create a series of big wins for you in the “get healthy, lose weight, look good naked” department.
In order for ketosis to happen, the body needs to be absent its preferred fuel source: glucose (sugar!).
This can happen in one of TWO ways:
Fasting: by not eating at all, your body will burn through your glucose stores and be forced to start converting fat to ketones for fuel.
Eating in a “Keto” way: essentially, only fueling your body with fat and avoiding consumption of foods that can be readily converted to sugar.
Where does that sugar usually come from? Generally speaking, carbs.[2]
And boy do we love carbs.
A typical American diet is more than 50% carbs. And more than 60% of our country is overweight. Is one causing the other? Or are they just correlated?
I’d argue both.
And I’m the nerd writing this.
So, there.
Eat carbs, burn carbs, store sugars, lather, rinse, repeat. Very little fat-burning is taking place – and you’re adding to your body’s sugar storehouse, and that’s what eventually winds up packing the fat onto your body!
This is an overly simplified video explaining the process:
So what happens if you get rid of those carbs and replace them with another fuel source? That’s when you start burning fat.
Compare a typical carb-heavy American diet to somebody who is “Keto” – they eat a diet very high in fat, with moderate amounts of protein and minimal amounts of carbohydrates.
Still with me?
Great.
So if you do an extended fasted period, or only eat foods that line up with the Keto Diet, your body is going to be forced to burn fat for fuel.
Another thing to note: when you eat carbs, your body produces insulin to deal with the increase in sugar/glucose in your bloodstream. When you minimize carbohydrate consumption, this can result in less insulin production, and your body can become more insulin sensitive, which has a host of health benefits.
Depending on how strict you are choosing to be with Keto, you’ll probably pick one of the following strategies:
Less than 50g of carbs
Less than 20g of net carbs
5% of your total calorie intake
Which one is for you? We’ll get to that. Just know that everybody is a unique snowflake, and everybody will be different when it comes to entering ketosis and staying in ketosis.
There’s no hard and fast rule to which “Keto Diet” strategy you need to follow, but it helps to start with one to get the ball rolling.
In short, you’ll need to pick the one that puts you into ketosis, which requires you to pay attention, track your results, and act like a scientist.
When you’re in ketosis, this can lead to ramped-up weight loss for some, and increased physical potential, lower insulin levels, increased brain function, and other awesomeness for others.
If you don’t care what ketones are and are just here for the weight-loss stuff, skip to the next section. If you do care about ketones, strap in and let’s get weird.
When your body doesn’t have carbs/glucose to burn for energy, you’ll need to dig into your body’s fat storehouse to get fuel.
Enter the hero of this story: your liver.
Yes, the same liver you abuse during dollar draft night at O’Houlihans.
In the absence of glucose, your liver takes your stored fat and breaks it down into usable compounds called ketone bodies, or ketones.
These ketones can be used by your body and your brain for fuel! In addition, “increased blood ketone levels may directly suppress appetite.”[3]
The reason many feel differently on a Keto Diet is that their brains are being fueled by a completely different source than at any point in the past.
There are three types of ketones, which is important to know if you want to sound pretentious at parties:
Acetoacetate
Beta-hydroxybutyrate
Acetone
It’s also important to note that ketones are different from a keytar, which is what Michelangelo used to defeat Shredder in the cinematic masterpiece, Ninja Turtles:
If you are wondering, “Steve did you write this entire section just so you could make a keytar joke?” you wouldn’t be wrong.
But let’s get back on track: There are two ways for your body to fuel itself off of ketones:
It can make the ketones itself during periods of fasting or due to the consumption of fat and the absence of glucose. Woot for home-cookin’.
Consume actual ketones – these are called “exogenous ketones,” which I’ll cover later in the article.
This concludes our boring sciencey section about ketones and allows us to get back to the real reason you’re here.
One of the tenets of the Nerd Fitness Rebellion is “You can’t outrun your fork,” which means we believe nutrition is 80-90% of the “lose weight” battle.
So let’s dig into how the Keto Diet factors in here.
When your body is consistently in the process of breaking down fat into ketones, you enter ketosis.
Imagine you have a pile of coal (stored fat) for the winter – when you shovel some of the pile into the furnace for heat (energy), your pile of coal gets smaller. In ketosis, YOU are getting smaller.
You can find study[4] after study [5] after study [6]in which people on a Keto Diet lost weight and improved tons of health markers.
There’s also another reason most people lose weight on the Keto Diet.
Thermodynamics.
I discuss this in great detail in my “The Perfect Diet” article, but I’ll give you the summary here:
When somebody eats a Keto Diet, they are nearly eliminating an entire macronutrient: carbohydrates.
And what foods are primarily made up of carbohydrates? Bread. Pasta. Candy. Soda. Chips. Bagels. Fruit smoothies. These are calorically dense, nutritionally deficient foods that people tend to overeat.
When you eliminate all of these bad foods in a restrictive diet like Keto, you’re going to consume fewer calories overall.
And when you burn more calories than you consume, day in day out, for weeks or months at a time, you’re likely to lose weight.
This is why most calorie-restricted diets result in weight loss regardless of the composition of the food consumed.
Note this ignores the concept of quality of food, muscle synthesis, body composition, etc. and JUST focuses on a smaller number on the scale.
Anecdotally, once some people become keto-adapted, they feel satiated on fewer calories – which results in easier weight loss.
And yes, the opposite is true: one can ALSO overeat on Keto in order to GAIN weight. So don’t expect to eat 6000 calories of butter, avocados, and bacon and lose weight.
In addition to helping with weight loss, the Keto Diet has been used to treat epilepsy[7], help with Type II diabetes[8], polycystic ovary syndrome [9], acne [10], potential improvement in neurological diseases (Parkinson’s[11] and multiple sclerosis[12]), certain types of cancer[13], and reduces the risk factors in both respiratory and cardiovascular diseases[14]. Emerging studies are digging into its effects on Alzheimer’s [15]and other conditions as well.
Here’s a video specifically related to Keto and cancer:
NOTE: I’m not a doctor. I don’t play one on TV. I did not stay at a Holiday Inn Express last night.
I am not advocating Keto as a panacea for all of your ailments.
I simply point out the above studies as STARTING points for you to conduct your own research and discuss with your doctor if switching to a Keto Diet is an experiment you should attempt.
Keto, Paleo, and Atkins are all considered “low carb” diets, though “low carb” means different things to different people, different groups, and different studies.
They each have different things that are important as well:
Keto targets low carb (less than 5% of your total), and focuses on a very high-fat content – 70% of your diet. It eliminates grains, tubers, and most fruits due to the carb content. You need to be diligent in your tracking and can measure if you’re in ketosis.
Paleo targets low carb through focusing on protein and fats, eliminates dairy, but doesn’t limit fruit or sweet potato intake. In this diet, you don’t track but rather eat until you’re full.
Atkins has different tiers of adherence, focuses on low carb, high protein, high fat. You eventually add more nuts, low carb vegetables, and low carb fruits back into your diet.
I’ve written a monster guide on the Paleo Diet, which I recommend you read in addition to this article if you’re trying to decide which option works best for you. You can also check out our post specifically comparing Keto and Paleo.
Like every diet, you can absolutely do any of these diets and still gain weight and get unhealthier – so they each come with caveats, and require you to understand the food you’re putting in your body.
Deal? Deal. Here’s an otter with a baby otter, you’ve earned it:
“Steve, I want all the potential benefits and potential good-looking side effects of going Keto. I also want a million dollars. But for now, I’ll settle for the benefits of Keto. How do I do it?“
In my opinion, there are two reasons why somebody wants to go Keto, and that should dictate your level of dedication to the Keto cause:
If you are just trying to lose weight, it doesn’t really matter whether or not you’re actually in ketosis – provided you are consuming fewer calories on average compared to how you were eating before. This can be aided by minimizing carbs and upping your fat intake.
If you are treating this as an experiment and are tracking your ketosis compliance, then you need to be more diligent in your tracking and actually make sure you’re in ketosis.
I imagine most people fall into Group A, but we’ll cover both Group A and Group B moving forward – and tracking your results is the best way to make progress.
So let’s say you’re “going Keto.” This can be a few different things depending on your situation:
Tracking net carbs: 20 net grams per day or less
Tracking regular carbs: 50 grams per day or less
As a percentage: 5% of daily calories
Although people adjust their ratio of protein and fats, the hard and fast rule tends to be around the severely restricted consumption of carbohydrates.
Ruled.Me has a fantastic Ketogenic Macro Calculator that simplifies the heck out of this process, but I’ll also show you the math if you want to nerd out:
#1: Determine your total calorie intake goal. Calculate your “basal metabolic rate” (how many calories you burn per day). I am 6’0″, 185 lbs, and my BMR is roughly 1814 calories. I am active, so I’m multiplying this number by 1.375 to get to my active daily calorie burn: 2814 – let’s make this an even 2800.
#2: Take 5% of that number for your total amount of carbs. Divide by 4 (there are 4 calories per gram of carbohydrate). Some people stick to a rule of “Less than 50 grams total” or “20 net carbs total.”
I have 140 calories for carbs, divided by 4, equals 35 grams of carbs. That’s a nice round number so we’ll stick to that.
#3: Next, calculate your protein requirements. If you are active, Target 0.8-1.2 g of protein per pound of weight. This is a simplified version of a complex calculation you can do, which is dependent on your lean body mass, how active you are, etc. If you have a lot of weight to lose, you’ll want to adjust this number down to more like 0.5-.6g per pound (consult the above calculator) You can multiply this by 4 to see how many calories total that would be.
I’ll again keep it simple and make it 180g for me. 180 x 4 = 720 cal. Which means so far I have used up roughly 860 calories of my 2800 calories, so I have 1940 calories remaining.
#4: What’s leftover? Fat! There are 9 calories per gram of fat. So divide your remaining calorie count by 9 to see how many grams of fat you should eat per day.
In my example, I have 1940 calories remaining, divided by 9, which means I need to consume 215g of fats per day. Yup. This is a lot of fat.
#5: Put it all together, write it down, start tracking your food, sucka! I’m sorry for calling you a sucka, I didn’t mean it. In my example, I’m looking at 215g of fat, 180g of protein, and 35g of carbs.
This should be a good STARTING point. You’ll need to adjust along the way based on how your body responds, but it can get you going.
Next, you’ll create a meal strategy of sorts – examples later in the article – that pick the foods in the previous section and combine them in a way that fits your particular strategy to enter ketosis.
And that means you gotta know your food!
For everything you eat, you want to know the following:
Number of calories
Grams of fat
Grams of protein
Grams of carbs
Grams of fiber
With carb intake requirements being very low, many ‘healthy’ foods would still be enough to knock you out of ketosis depending on how many of them you eat. Which means you need to be hyper-aware of your carb count.
Let’s quickly talk about the concept of “net carbs,” and why this is so important:
A vegetable that is 5 grams of carbs and has 3 grams of fiber will have a “net carb” total (subtract the fiber number from the carb number) would be 2.
Here are a few examples showing the ‘net carb’ effect:
Asparagus: 7g carbs, 4g fiber = 3g net carbs
Kale: 7.3g carbs, 2.6g fiber = 4.7g net carbs
Broccoli: 11g carbs, 5g fiber = 6g net carbs
WHY THIS IS IMPORTANT: Fiber is really good for your body, and oftentimes when somebody goes from eating hundreds of grams of carbs per day to less than 50g, they are eliminating a lot of high fiber foods they used to eat (bread, whole grains, etc.).
By consuming leafy greens like kale or veggies like broccoli, one can still get enough fiber and remain in ketosis.
Of course, no good healthy eating strategy goes unmarketed, why you’ll see plenty of “Keto-friendly” snacks that advertise “zero-net carbs” even though they have many grams of carbs in their nutritional breakdown – it’s countered by the fiber.
In addition, a lot of “high fiber” protein bars or “low carb snacks” often contain sugar or artificial sweeteners that could knock you out of ketosis.
Which means two things:
Consuming a pile of “Keto-friendly” processed snacks all day long could absolutely knock your body out of ketosis. Check the ingredients, and try to focus on eating REAL food.
If the occasional Keto snack keeps you from getting hangry (hungry plus angry) between meals, and keeps you from overeating during your regular meals – knocking you out of ketosis – then snacks are fine.
“Steve, I appreciate you talking to me like I’m 5 years old and walking me through this process step by step. I don’t care what everybody on the internet says about you, you’re an okay guy.
I now have my macros. What the heck do I get to eat on a Keto Diet?”
As I explained above, in order to be in Ketosis you need to eat a diet that has minimal carbs, high fat, and adequate amounts of protein.
Following this type of nutritional strategy can result in ketone body production and increased fat-burning. We talked about this in our Beginner’s Guide to the Paleo Diet. Although fat gets a bad rap, fat is an essential nutrient and it’s not actually the fat that’s making us fat.
Here’s a look at the things you should primarily be eating on Keto:
Meat. This includes red meat (like steak) as well as pork products (sausage and bacon and ham) and white meat (like chicken and turkey). Fatty meats can be helpful in a Keto Diet.
Fish. Look for high-fat fish, like tuna and salmon.
Eggs and dairy. If you think there’s nothing better than butter and cheese, you’re in luck! Eggs, butter, and cheese are all a big part of eating Keto. You’ll want to make sure your items are as unprocessed as possible, so stick to cheeses like cheddar, mozzarella, and blue, and look for butter and egg products that are organic or come from free-range animals.
Healthy fats. Nuts, seeds, and avocados are your keys here. Almonds, macadamia nuts, Brazil nuts, and nut butters.
Dressings and oils. Greek dressing, caesar dressing (though check the ingredients), ranch, aioli. When you need an oil, stick to extra-virgin olive oil, avocado oil, coconut oil.
Veggies. Cruciferous greens like spinach, kale, broccoli, cauliflower, that sort of thing.[16]
Meatless proteins. Tempeh, tofu, and seitan can take the place of meats in a vegetarian or vegan Keto Diet. Not as optimal in this nerd’s opinion, but you do you, boo.
This is an overly simplified breakdown of what you can eat, but it will serve as the foundation for the rest of the article. And yes, I’ll get into specific meals soon.
Now let’s cover all of the foods you should avoid while eating Keto:
Sugars. This can include desserts like cake and ice cream and cookies. And don’t forget to watch out for hidden sugars in things like ketchup! Your body LOVES to burn sugars, and if it has those, it’s not going to create ketones out of fat to burn. Liquid calories. Soda, juices, smoothies, and any beverages that contain carbs and sugar.
Starches. This means pasta, potatoes, sweet potatoes, rice, bread, cereals, and anything made with wheat or cornflour. They’re big sources of carbs, and once again, they’ll stop your body from entering ketosis. It also means corn, which is a grain, not a vegetable.
Diet foods. We told you to avoid sugars, but “diet” foods are big red flags on Keto as well (and on most healthy eating plans!) They’re heavily processed and high in sugar and tend to wreak havoc on your body.
Fruits. What, no fruit? Fruits tend to be high in fructose (a sugar). High sugar = no ketosis. (I feel like maybe I’ve said that already). A few berries can be OK, but only if you’ve planned for their net-carb intake into your daily total.
Beans.Wait, what? Steve, I thought beans and legumes were healthy! You even eat them as part of your Paleo-ish diet! They can be, but they’re also higher in carbs and can potentially cause inflammation that works against weight loss.
Unhealthy fats. Healthy fats, like those in olive oil and nuts, are great. But that big glob of mayonnaise in your tuna, or the canola oil you’re frying in? Stay away from them on Keto.
Does this sound like a lot to eliminate all at once? It’s because it is. This is where most people fall off the wagon.
They see that list and say “I could never give up (insert your favorite non-Keto food here).”
If you’re already overwhelmed and worried you can’t stick with this diet, I got ya. I made a free 10-level Diet Blueprint (think like leveling up in a video game) that walks you through eliminating many of these foods through a series of small changes you can make that won’t freak you out, and isn’t nearly as restrictive as the Keto Diet.
For a lot of members of the Rebellion, these incremental changes are a great place to start while you get your feet wet and start to learn about the food you’re cramming down your piehole. I’ll send it to you free when you sign up in the box below:

What you need to know about weight loss and healthy eating
3 Simple rules we follow every day to stay on target
If you’re going to follow a Keto Diet, you probably want to learn how to determine if you’re actually in ketosis, right?
I believe there is something more important here to consider:
Are you getting results?
Does it matter?
If you are aiming for a “look pretty good, feel pretty good” strategy – as laid out here – an 80% solution that results in a decent physique when combined with strength training and exercise.
So if you “go Keto” and you are losing weight and feeling better, does it REALLY matter if you’re in ketosis or not? I don’t want your success derailed because you panic about the exact amount of ketones in your bloodstream!
“Steve, I hear you. But I’m doing this Keto thing as an experiment, or I want to see if I get other benefits too. Tell me how I can measure my ketone levels!”
Okay okay okay, fine! We’ll do all the things that YOU wanna do.
There are three ways to determine whether or not you’re in Ketosis:
Test your breath
Test your urine
Test your blood
In my research, I found that testing one’s breath is the least popular of the options – I only found poorly reviewed expensive testers. So if you happen to LOVE this method and have an inexpensive testing option you want me to link here – put it in the comments!
Blood testing options are accurate but do require a blood sample (duh) and thus are less convenient than the next option…
I bought these Ketone Testing Strips and they seem to be getting the job done for testing the level of ketones my body is producing. I simply pee on the strip and then match the color at the end to the side of the bottle to determine the level of ketones in my urine.
For the first week or two of becoming keto-adapted, testing your ketone levels daily (or once in the morning and at night) is reasonable. Don’t test your levels multiple times throughout the day, especially after just eating, and then freak out if the number isn’t what you wanted it to be.
NOTE: Once your body becomes fat-adapted, it might use ketones more effectively which means fewer ketones are excreted through your urine/breath. For this reason, your tests could show lower ranges of ketone levels than the actual amount your body is producing. This is normal, expected, and not a problem.
“WHAT ARE THE DIFFERENT RANGES FOR KETONES!?”
Ketones are measured in terms of millimoles per liter in your blood:
0-0.4 mmol/L = regular American diet (50%+ carbs)
0.5-7 mmol/L = prolonged fasting / ketogenic diet
15-25 mmol/L = Diabetic ketoacidosis = danger, Will Robinson!
When you’re in ketosis, you’ll hang out in the second range. Depending on what you’re eating, if you’re supplementing with exogenous ketones, if you fasted, and how long you’ve been in ketosis, where in that range might vary for you – but that’s okay!
My research also showed that there’s no particular benefit to having a higher ketone amount as long as you are in ketosis.[17]
Let’s quickly talk about ketoacidosis – it’s a condition in which the body produces too many ketones that can’t be used, rendering the bloodstream too acidic – it’s a concern, but for a small percentage of people.
Diabetics in particular are at risk for diabetic ketoacidosis, and they should work with their doctor before adjusting their medication or adopting a Keto Diet strategy.
If you are STILL panicked, speak with your doctor. And relax. Look at these sleeping puppies, calm yourself down, and then we can get back to work:
As previously stated (like, 5 minutes ago), there are two ways to ensure you get into ketosis:
Fasting
Eating in a way that induces ketosis (low carb).
As many will tell you in the Reddit’s /r/Keto – and even members of our own Team Nerd Fitness:
Eating Keto + Intermittent Fasting = a great combo for simple weight loss.
We actually have an amazing success story here on Nerd Fitness, Larry, who followed our strategies, decided to go Keto and start intermittent fasting. He ended up losing weight, getting stronger, AND overcoming the challenges of rheumatoid arthritis (click on the image for his story)!
Only eat during a certain window of the day. The most popular version (and the one I follow) is ‘skip breakfast’, and only consume calories between Noon and 8PM.
Occasionally do a 24 hour fast: eat dinner one night, and then don’t consume more calories until the following dinner. Some people actually do this every day, they call it OMAD (one meal per day).
Men and women are affected differently by intermittent fasting, and your results may vary.
As your body enters a fast period when there are no sources of glucose energy readily available, the liver begins the process of breaking down fat into ketones. Fasting itself can trigger ketosis.
Fasting for a period of time before kicking off a Keto-friendly eating plan COULD speed your transition into the metabolic state of ketosis, and fasting intermittently while in ketosis could help you maintain that state.
I personally love fasting for the simplicity: I skip breakfast every day and train in a fasted state. It’s one less decision I have to make, it’s one less opportunity to make a bad food choice, and it helps me reach my goals.
WHY KETO + IF WORKS = eating Keto can be really challenging. And every time you eat, it’s an opportunity to do it wrong and accidentally eat foods that knock you out of ketosis. You’re also tempted to overeat. So, by skipping a meal, you’re eliminating one meal, one decision, one chance to screw up.
Note: if you’re thinking “Steve, am I losing weight because I’m skipping 1/3rd of my meals for the day, AND eliminating an entire macronutrient?” – Yes. Now, both Keto and IF have secondary effects that could also be factoring in.
Your value may vary!
You need to decide what works for you: If going 24 hours without eating would make it hard for you to be successful on Keto, similar results have been seen when starting the diet without a fast, so don’t worry if that’s not doable right now!
Some people find success in eating ONE big meal a day, others do 16/8 fasting, and other people eat throughout the day.
It comes down to total calories consumed, total carbs consumed, and your level of misery while adjusting!
Keto needs to work for you, not the other way around. And if you want to try Intermittent Fasting, you can download our free IF Worksheet to track exactly when to eat and not to eat!

Keto-induction, or the period where your body is entering ketosis, is a pretty big shock to the system, especially if you’ve been eating a lot of carbs. It can come with side effects that feel like the flu (fatigue, upset stomach, aching, insomnia and more), but it’s not caused by the ketosis itself.
Keto flu actually comes from carbohydrate withdrawal. That’s right; your body can basically be addicted to carbs, and have trouble dealing with a reduction in them!
It takes time for your body to become “Keto-adapted.”
Think of it this way: your body is a spoiled toddler who has been happily fueled by candy and soda for the past 3 years.
You suddenly tell the toddler: “no more soda, no more candy. You’re going to eat broccoli and grilled chicken like a big boy.”
How do you think this kid is going to respond?
Poorly.
Temper tantrums, mood swings, crying, and rage at the lack of delightful sugar. Eventually, this kid will be better off in the long term as a result…but it’s gonna take some time.
This ‘carb withdrawal’ can be so dramatic for some people that it ruins them for days or weeks, and they give up.
In these instances, the love affair with Keto ends prematurely, and the person goes crawling back to the comforting, delicious, but ultimately unfulfilling carb-heavy comfort foods.
Remember that list of ‘worst’ diets with Keto at the top? It’s for reasons like this: people give up on the diet quickly, and it’s tough to stick with long term.
“STEVE, HOW CAN I AVOID THE KETO FLU?”
For MOST people, the Keto flu and getting headaches comes down to the body adjusting to becoming fat-adapted, dehydration, and electrolyte imbalances. When you eliminate carbohydrates from your diet, you might also be removing the consumption of certain electrolytes:
Sodium
Magnesium
Potassium
When you specifically try to add these electrolytes back into your diet, you’ll be able to offset some of the chemical changes in your body and compensate for the lack of those electrolytes that you used to consume as part of your old diet.
How does one do that? For sodium, you can simply add salt to your food (heyyyy sodium!), and for potassium and magnesium, you can eat kale, other leafy greens, avocado, nuts.
And in BOTH instances, you can add electrolyte supplements to a bottle of water!
I have many friends who struggled through the first few weeks of Keto and found that electrolyte supplementation made the process significantly more bearable.
“Steve, I’m down to try Keto. But I don’t just want to lose weight, I want to build a physique I’m proud of. Meaning I wanna look good nekked.”
We’re going to approach this section with three caveats:
I don’t care what the “optimal” way to eat or train is. Unless you are an elite-level athlete or trying to build a specific physique, being “good enough” will suffice. This is true for your nutrition, for your training. The OPTIMAL way for you to train and eat is whatever method you will actually stick with long enough to build the habit!
We’ll look at what happens to your body on both cardio and strength training. You’ll be covered no matter what kind of exercise you follow.
You might suck at everything for the first few weeks of Keto. As pointed out in The Ketogenic Bible: “Significant declines in physical performance after one week of following a Ketogenic Diet; however, performance levels are restored after about six weeks, although it sometimes takes longer.”
The jury is still out on all of this –studies have suggested that reducing carb consumption dramatically could impact performance negatively depending on the activity, and below I’ll show you studies that present the exact opposite conclusion.
#1) “Steve, I like Strength Training. What does Keto look like for me?”
Great. I do too. In fact, I train in a fasted state four days per week. When you strength train or train intensely, your body starts to use up the glycogen stored in your muscles.
And you’re probably wondering “Steve if I don’t consume carbs, which becomes sugar, which my muscles store as glycogen…am I gonna run out of glycogen and my strength training might suffer?” Good question. Maybe.
“Does eating in a Keto way alter your body’s reliance on glycogen stores in the muscles? Does it change how much glycogen your muscles use or how quickly these stores are replenished?” Maybe. We’re still learning.
I did find multiple studies in which strength training was either not impacted or positively impacted by a Keto Diet:
A 2012 study put 8 male gymnasts on a 30 day Keto Diet – they lost more fat mass and increased lean body mass while. Suggesting Keto can help with body composition, which is probably why you are strength training to begin with.
A 2016 study looking at CrossFit programming showed no significant difference in muscle mass or performance between a Keto group and a control group.
A 2017 study worked with 25 strength training men – both groups gained muscle mass, while the Keto group lost more fat.
Now, this isn’t law, more studies are being done as we speak, and your results may vary. What this simply means is that there have been studies done that show one can do resistance training or CrossFit while eating Keto and not lose gains or muscle mass. Other studies show the opposite. Which means…
Your results MAY vary. Make sure you give it enough time to push through the Keto flu, performance-suckage phase to get a true answer for your situation.
Also: unless you’re a competitive athlete or compete in powerlifting competitions, this might not matter as much! Athletic performance is often negatively impacted once somebody gets to a low enough body fat percentage, but it doesn’t stop people chasing that “ripped” six-pack abs look!
#2) “Steve, I’m a runner/biker/etc. and I always carb-load. Sounds like Keto isn’t for me, right?”
Maybe not. Your body can only store 1600-2000 calories worth of glucose at any time – but might have 40,000+ calories worth of fat stored in the body. So instead of having to consistently eat gels and goos and snacks to keep the glucose levels high, what happens if you switch to “Keto-adapted” and fuel yourself with fat?
Let’s go to the science:
Earlier studies had suggested that a moderate-carb diet provides better endurance by increasing the concentration of glycogen in your muscles, but newer research seems to be swinging more in the direction of Keto.
As it turns out, the Keto Diet has been tested in ultramarathoners, Iron Man trainees, and endurance athletes in multiple studies, and in all cases, ketosis resulted in enhanced body composition and some of the highest rates of fat-burning ever recorded!
A 2016 study looked at 20 ultra-marathoners and Ironman distance triathletes – half of which were instructed to be on a fat-adapted diet for at least 6 months and the other 10 were on a traditional carb-focused nutritional strategy. The results:
Both groups had the same perceived level of exertion during a 3-hour trial run.
The Keto group had a fat oxidation rate of 2.3 times higher than the carb group, at an average of 1.5 grams per minute.
There were no significant differences in pre- or post-exercise glycogen concentrations.
Just like with strength training, this MIGHT work for you – or you might better off as a carb-adapted runner and athlete. You have to do what works for you.
My above caveat still stands: unless you are an elite athlete, this should be less of a concern for you – follow the diet that makes you look and feel good, and then base your training progress off your previous day’s results!
#3) “Steve, I’m not a competition-level ANYTHING, but I like exercising and want to look good.”
While dietary changes make up at least 80% of your weight-loss efforts, exercise will help you stay healthy and build a body you’re proud to look at in the mirror.
So track your workouts, track your nutrition, and work on getting better with it – running one second faster, doing one more rep, lifting 5 more pounds, etc. Compare yourself to your past self.
#4) “Steve I read this study that says Keto + Athlete = good/bad/ugly.”
Fair. Do what works best for you! In my research, and in learning from people that I trust and admire in this space:
Studies are often focused on short term ketosis (a few days or weeks), which could result in adverse performance in athletes who have not become fully Keto-adapted yet.
We are all unique snowflakes and your mileage may vary depending on your physiology. So who cares if you lift 5 pounds less! If Keto works for you and makes you look better, keep doing that.
If you are going to try Keto + Strenuous Exercise, consider the following advice: Keto might work for you! It might not!
You’ve read this far, learning about how our body has to work hard to create Ketones for energy.
And you’re probably thinking what I’m thinking: “What’s the airspeed velocity of an unladen swallow?” “Can’t I just ingest ketones directly?”
They refer to these as “exogenous ketones,” if you were wondering.
You weren’t, but that’s okay.
Caveat: I have not consumed exogenous ketones, though I have heard they can taste like jet fuel. And they can be pricey – though coming down in price thanks to Keto’s popularity.
So, if you LOVE to drink expensive jet fuel for some potentially better results or higher athletic performance, best of luck to ya.
The two types you’ll encounter are:
This 2017 study showed “exogenous ketone drinks are a practical, efficacious way to achieve ketosis.”
In addition, A 2018 study showed that consuming Ketones lowered ghrelin [18] and thus our appetite.
I would put exogenous ketones in the “only if are aiming for strict ketosis” category, if you’re an elite athlete, or seeking a specific outcome of a medical condition under professional supervision.
If you really want to nerd out about exogenous ketones, consider this article from somebody I respect and trust, Dr. Peter Attia, on his experiences with them.
I won’t delve too much deeper into the topic until I can experiment with them myself and report back!
“What about other supplements Steve? I can’t get enough fat in my diet!”
In the previous section we discussed electrolyte supplementation, and for somebody that’s an athlete or unable to get enough protein in their system, a high-quality protein powder can help – just note the carb content!
Many people struggle to get enough fat in their nutrition, and have found success fat supplementation with MCT (medium-chain triglyceride) oils and powders.
These are two types I’ve experimented with:
MCT oil can cause digestive challenges and make you immediately run to the bathroom, while the powder version might not cause as much of an issue. This was my experience.
Your mileage (to the bathroom) might vary! Start with small amounts of MCT before increasing the quantity.
Outside of these suggested supplements, the best “supplement” is a healthy eating plan. I know I know, a cop-out answer. If you need more sodium, first try adding a little salt to your meals. If you need more potassium, eat some spinach before you head to the supplement aisle at the grocery store.
Not only will these methods help you feel better, but you’ll be setting yourself up for better long-term eating habits.
Our overall stance on supplementation here at Nerd Fitness: supplements cannot replace the effects of a healthy diet and regular exercise. But for some people, these might be the right fit.
Homestretch! Now we just have delicious food and fun stuff to discuss. Yayyyyy!
“Steve I know I can eat things like meat, cheese, and vegetables, but I’m gonna go ahead and need you to do the heavy lifting for me. Give me a sample day on Keto and links to recipes.”
I considered saying “Let me google that for you” when it comes to “Keto recipes”, but I’m too nice of a guy.
Let’s hit the big three meals to start:
BREAKFAST:
LUNCH:
DINNER:
CONDIMENTS: Ruled.Me has some great resources on what Keto condiments you can use to spice up your dishes without losing ketosis.
Here’s a quick list:
Coconut Oil
Olive Oil
Heavy whipping creme
Full fat cream cheese
Full-fat sour cream
Mayonnaise
Mustard
Full fat Ranch, Caesar, Bleu, Cheese, Italian
Depending on your macros, you might be adding butter, ghee, fatty dressings or oils, or supplementing with MCT/Coconut oil to hit your macros for the day.
This should at least get you started in thinking that you can still eat AMAZING food while eating Keto.
Everybody loves snacks. Unfortunately, most of the snacks you’ll encounter anywhere are definitely not Keto-friendly.
I’m firmly on Team No Snack, as I do practice intermittent fasting and try to eat BIG meals instead of lots of small ones – as I point out in the Intermittent Fasting article, the number of times you eat throughout the day won’t impact your waistline as much as the total quantity of calories.
That’s right, your metabolism isn’t “stoked” by eating small meals or grazing throughout the day. You can get in trouble if you eat big meals and then eat snacks between those big meals.
What matters is overall compliance – if snacking in between meals allows you to NOT overeat during your big meals, and ALSO you stay under your caloric intake goal for the day, then snacking is more than okay.
As far as dessert goes, the same holds true: if you save room in your macros and calories for a low calorie, Keto-compliant dessert, go crazy. Just don’t delude yourself into thinking that eating 5,000 calories of “Keto cookies” and “Keto ice cream” is going to make you healthier.
Got it? These snacks and desserts need to fit into your macros/calorie goals in order for this whole “I went Keto” thing to actually work for you.
EASY KETO SNACK IDEAS. If you want a bunch of Keto Snack ideas, check out our MASSIVE 60-snack guide on the subject. However, go ahead and think about these for now:
KETO DESSERT IDEAS:
Outside of Keto snacks and Keto desserts which everybody asks about, there’s one other big question that you probably have…
You’re gonna need to be super diligent with your carb counting when it comes to your adult beverage choices.
A Sam Adams has almost 20g of carbs, enough to knock somebody out of ketosis after just one. As a Bostonian, this makes me sad.
This is even worse for mixed drinks! No more rum and Cokes. No more margaritas. No more old fashioneds with simple syrup. No more daiquiris or mai tais or piña coladas.
Instead, you need to do your research into the carb content and calorie count of your favorite alcoholic drinks:
If you’re drinking spirits, mix with club soda (NOT tonic, which is loaded with sugar) or learn to drink neat.
If you’re drinking beers, opt for the low-carb variety! Just Google the beer brand you’re considering and go from there.
Just like with desserts and snacks, you need to make alcohol work for your macros and your calorie counts for the day.
Other things to note about alcohol: you might get drunk much faster as a result of being in Ketosis, you might have a worse hangover, and you might wake up in a chicken costume covered in sriracha on the other side of town if you drink too many “Keto-friendly” whiskeys.
Phew. This article was focused on telling you everything you need to know so that you can confidently get started with Keto.
I want to give a HUGE shout out to the book, The Ketogenic Bible, by Dr. Jacob Wilson and Ryan Lowery, which was my first stop in my Keto research.
If you’re a super nerd and want to learn about all of the science behind this stuff, or if you’re intrigued by the research into Keto + certain health conditions or improvements, it’s absolutely worth a read.
If you’re interested in going further with your Keto adventure, consider all of the following below!

KETO RECIPE AND OTHER RESOURCES – In addition to simply googling “Keto recipes” which I know you can do because you’re a big boy or big girl, here are three of my favorite resources:
PODCASTS ABOUT KETO: If you love to listen instead of reading, I’m doubly proud of you for making it all this way. Here are three of my favorite podcast episodes on the subject, in order of complexity. The science versus is the most approachable:
Okay, you’re here because you’ve committed to going Keto, and now there’s just one final step: actually doing it.
So how do you get started? What’s next for you between reading this article and 30 days of Keto success? A plan!
Fear not, for I have built a step-by-step plan for you right here:
#1) Take before photos and measurements.
Take front and profile photos of yourself. You don’t need to look at them or share them anywhere, but I PROMISE you’re going to want those.
Record your weight and take any measurements you want.
Write this stuff down and keep it secret, keep it safe.
#2) Calculate your calories and macros. You can do the math as I explained above, or simply use the calculator over on Ruled.Me. Know your number of goal:
Calories
Carbs
Fat
Protein
#3) Go shopping for your Keto foods, and order your Keto snacks on Amazon. Look at the recipes above and pick the ones that don’t scare you to make. Keep snacks readily available in case of “holy crap I am so hungry and I just want to eat a damn pizza and spaghetti and snort Pixy Stix.”
#4) Consider picking up an electrolyte supplement to help you through the first few days/weeks of grogginess/lethargy as you move through the Keto flu stage. You can also look into the urine test strips or blood testers – I find that knowing I’m in ketosis, it helps keep me accountable and motivated that all these changes are actually working!
#6) Tell somebody. The biggest problem with Keto is simply sticking with it. If you have roommates or a significant other or friends you can speak to and get them on your team to support you. In fact, send them this article and recruit them to try it with you! That way they’re not enabling you to slip up, they’re keeping you accountable!
Don’t have anybody to tell? NF Prime has the most supportive community on the internet.
7) Consider kickstarting your week with a fast. This is going to be a mental and physiological challenge. Consider skipping breakfast tomorrow – it’s one less meal you have to prepare, one less chance to knock yourself out of ketosis, and can help kickstart the Keto-adapted phase!
8) Throughout the week: Focus on big wins, allow yourself to be miserable – Keto flu is REAL, giving up carbs is hard, and your body is going to hate you:
Lean on your support group. Talk to others who have been where you are, ask questions, share your struggles!
Eat snacks when you are miserable. I’d rather you eat some snacks and slightly overeat on your calories than be so miserable that you give up.
Track your adherence. Use MyFitnessPal (though not their recommended macronutrient breakdown!) to track every meal you eat – this is very important in the first week as you’re educating yourself dramatically.
Do your best – you might slip up with one meal or realize you accidentally ate carbs. This is not the end of the world. Forgive yourself, learn the lesson, and get right back at it with the next meal.
9) Keep going, or adjust. Depending on your body, your environment, the way you used to eat, and your physiology, this first week will either be “hey, not too bad” or “Never again.”
Either way, you’ll learn something. I do hope you push through this for a full 30 days and see how your body responds once it’s out of the Keto Flu stage!
10) At the end of the month, take more photos and measurements and compare them to your starting “before” stats. Do you feel better? Do you look better? Did you enjoy the process? great! Keep going. Hated it? Great! You found a method that doesn’t work for you. Adjust and create your own strategy.
Very important question. We all know this article is NOT medical advice, and regardless of your health you should discuss your nutritional strategies with your doctor or dietitian.
As pointed out in The Ketogenic Bible, going into Ketosis is not recommended for:
Carnitine deficiency
CPT I/II deficiency
Beta oxidation defects
Impaired gastrointestinal motility
Pregnancy
Kidney failure
Type 1 Diabetes
Pancreatitis
Gallbladder disease
Impaired liver function
Impaired fat digestion
Gastric bypass surgery
Abdominal tumors
If you’re concerned about your health with regards to Keto, speak with your doctor and consider a Keto Diet under supervision.
2) Do I have to count calories on Keto?
Not necessarily, but it certainly helps when starting out. That is true whether you’re doing Keto or just trying to eat healthier. In fact, I would almost make it a requirement until you learn the basics about everything you eat.
The most important thing you’ll need to track is your carb and fiber intake. You’re trying to eat less than 20-50 grams of net carbs each day, and making your diet 70% fat. Not all calories are created equal when it comes to healthy eating and weight loss, so they’re not a focus on Keto.
3) Eating all of this fat and cholesterol is going to make me fat and block my arteries, right?
Wrong! Dietary cholesterol has been shown to not increase blood cholesterol – check this article here. And fat is healthy when consumed as part of a nutritious meal. As pointed out in this study, a Low Carbohydrate Diet resulted in decreased bodyweight, abdominal circumference, diastolic blood pressure, triglycerides, insulin, and an increase in high-density lipoprotein cholesterol (the good stuff).
It’s when fat is combined with carbohydrates in diabolical combinations that we start to get into trouble.
4) I’ve heard my breath and my urine might smell funny on Keto. Is that true? What do I do about it?
Look, we don’t want you to be self-conscious about how your pee smells. But it’s true; as part of the byproducts produced through the creation of ketone bodies, you may notice a fruity smell in your urine and on your breath.
This is totally normal, and it comes from the acetone that’s produced through ketosis. Acetone isn’t used for energy, so it’s excreted in urine and breath.
Not only is this not bad, but it’s a sign that you are fully in a ketogenic state.
But you probably don’t want your breath to smell like a slightly weird fruit salad, right? The easiest answer is to brush your teeth often, and to wait it out. This effect usually goes away once you’re on the diet for a while as your body learns to use more ketones.
5) Can I eat Keto if I’m a vegetarian/vegan?
Yes. We mentioned above in our list of foods to eat that you can substitute meatless proteins for meat in a vegetarian Keto Diet. If you also want to remove the dairy and eggs to make a vegan Keto plan, in addition to the vegan meat options, consider adding mushrooms and “vegan dairy,” such as full-fat vegan cheeses, as well as a larger quantity of healthy fats like coconut oil.
You can follow the low-carb principles of keto along with your vegetarian or vegan eating plan. Also, if you’re interested in following a Plant-Based Diet in general, make sure you check out our massive guide on the subject.
6) Does this mean no carbs forever and ever? How long am I supposed to go Keto for?
You will get results from Keto for as long as you stay Keto. If you go Keto and lose a bunch of weight, but then go back to how you were eating before…you’ll end up right back where you started.
So, our advice would be to give this a true attempt: stick with Keto for 30 days as an experiment. You might find that you LOVE how it makes you feel and want to stick with it.
Also, as your body learns to become keto-adapted, you can start to mix in sliiiightly higher carb days here and there with minimal adverse effects.
If you go Keto and decide that this is not the best strategy for you, that’s cool too. Pick the parts of it that work for you, take what you’ve learned, and start to experiment and build your own diet.
The Keto Diet COULD work for you…if you can stick with it. And even if you stick with it, it might not be the right diet for you. It isn’t for me.
I do think learning about the Keto Diet, learning your macros, and getting a better understanding of how you fuel your body is a good thing in the long term.
So here’s what I would recommend: Be less concerned about “staying in ketosis” and instead concern yourself with how to find a nutritional strategy that fits YOUR life.
If you’re adamant about going Keto, try it out for 30 days. If you have health concerns, discuss this with your doctor first. Take measurements and before and after photos, and then determine after 30 days if it works for you. And if it does or doesn’t, adjust and course correct.
The worst thing to do would be to go Keto for 30 days to try to lose weight quickly, just to go back to how you were eating before.
Instead, we want you to make permanent progress. So find a path that allows you to be pretty damn good, nearly all of the time.
Whether or not Keto is for you, keep looking around here at Nerd Fitness. Maybe Paleo or Intermittent Fasting is a better fit for you, or you’d prefer to work with a coach to help combine all of the above into a system that fits your exact lifestyle.
Whatever it is, I’m glad you’re here. And I’m glad you’re trying.

PPS: I guarantee I probably pissed off half the internet for some reason with this article.
Whether it was a typo, the fact that I referenced a particular study that didn’t line up with your already deeply-held view on Keto, or because you don’t like my jokes. I hope we’re still cool.
