By now, most of us have heard about the ketogenic diet. Whether it's because of the benefits of eating high-fat and low-carb, or because you can eat cheese all day long, it's officially become one of the hottest diets of the year. It may not be easy to cut out all the carbs, but emerging research suggests that eating fat can actually help burn fat. So, for anyone trying to lose weight, you may find it worth the carb cut. Beyond weight loss, recent research has found some other serious health benefits of keto that may impact your life later on. Let's take a look at what the research has to say.

Although we love them to death, our Mom’s typically have zero authority on the subject. When Mom heard you were going on a ketosis diet the first thing she did was head to google hell bent on finding any information about the dangers of the diet. Sure enough, 10 pages into google she found what she was looking for… Never mind the first 9 pages filled with information about the safety and merits of the diet.
Casual chronic keto is at some risk of those same side effects. Sure, there are sporadic anecdotal cases where there appears (so far) to be no harm, but these are not large population RCTs. The KD-in-epilepsy data is closer to being RCT data. There being no ancestral case for chronic keto, we need to learn what we can from the formal studies (and sure, endeavor to separate the ailment, med and diet effects).
Abbey, I appreciate all the work you put into this but there are a few things you missed. Not all oils are keto friendly. Vegetable oils are a huge no-no which was not mentioned. Regular mayo usually contains soybean oil which should be avoided. You also missed that foods with preservatives are a no-no which excludes some cheeses (you said enjoy all the cheese you like). Processed sliced cheese or pre-shredded cheese in a bag at the grocery store contains preservatives. Ever notice how shredded cheese in a bag never sticks to itself but when you shred your own cheese it sticks? Preservatives. Most nuts are okay but peanuts are a legume and should be consumed in very small amounts or avoided altogether. Don’t go crazy either, nuts do have carbs. I don’t eat more than a half cup a day of salted almonds. That said, you could have mentioned that getting salted nuts is ideal as you do excrete more salt and other minerals in your urine (eating keto is diuretic so attention must be paid to salt, potassium, magnesium, etc. as you did mention) so finding simple ways to add salt and other minerals is helpful. I also take a multi-vitamin daily. You mentioned you cannot do high intensity workouts. You are not supposed to do high intensity workouts as elevating your heart rate too high actually stops the fat burning process in your body. Your heart rate should be 180 beats minus your age +/- 5 beats depending on fitness level. A 40 year old obese person shouldn’t go over 135 beats/min during a workout as that is the optimal fat burning window. Higher than that and your body reverts to storing fat reserves thinking it will run out if it keeps this pace. Which bring me to metabolism. Its been long believed a high metabolism is good. A high metabolism leads to more hunger (because you’re burning glucose faster), ingesting more food, and typically gaining more weight. Slowing your metabolism down AND teaching your body to consume slow burning ketones instead of quick burning glucose puts less stress on your liver mainly and on your body in general. There’s a lot more but this is getting long so I’ll finish with this. You said this diet focuses on quantity of food and not quality. This is confusing to me….wouldn’t organic and grass-fed meats, be of better quality than non-organic and grain fed meat? (they feed animals grains to fatten them up….shouldn’t that be a huge warning sign for us?). Is food without preservatives not better quality than food with preservatives? Aren’t beverages with no sugar or artificial sweeteners of better quality than sugar/artificial sweetener-filled beverages? I’ve never seen any keto advocate advise ignoring quality foods, in fact its quite the opposite.
The keto diet involves getting up to 80 percent of daily calories from sources of healthy fat, a significant change for most of her patients who were accustomed to running on carbs, caffeine and sugar for energy. It became clear that something else had to be adjusted in order to prevent the side effects associated with the keto diet. This is when she came up with the idea to focus on restoring alkalinity first and foremost.
During ketosis, your body produces ketones, or byproducts of the fat-burning process. Your body uses several tactics to remove the ketones from your body, including exhalation. When ketones are excreted by your lungs, they leave as foul-smelling acetone. Because of this fat-burning process, you may develop bad breath while you’re in ketosis. Drink plenty of fluid to help your mouth stay hydrated and reduce the risk for bad breath. If the situation becomes particularly smelly, you can turn to sugar-free mints or gum to mask the situation.
I won’t comment on the diet itself but dietitians do not simply rely on guidelines handed to them, nor on anecdotal cases. This article refers to specific studies all throughout, some that support the diet and others that don’t. The goal of a dietitian is to help clients reach their optimal health while still enjoying a high quality of life. I’m sure Abbey is genuinely happy for those it has helped. That does not mean this diet is best for everyone regardless of their unique circumstances, goals and medical history. Sadly there is not enough high quality research that Keto promotes sustained weight loss in the general population. Maybe there will be in the near future, but right now it would be unethical to recommend such a restrictive diet to the broad audience of a blog. I am truly happy it has worked for some people and I wish them luck on their journey. Thank you Abbey for a great article!
But what I think is funny is that the keto diet has been staring us in the face forever. Look at Inuit tribes that survived off of blubber in a region that grows next to nothing most of the year. Yet their people didn’t die out or show signs of metabolic disorders or heart disease until introduced to the modern western diet that prioritizes carbohydrates over fat. Here is an interesting link, however I find the conclusion disheartening and frankly more than a little suspicious. (Basically the people in charge decided to drop the study and introduced a bunch of “what about…” questions to obfuscate a clear pattern in observation across many indigenous people from across the face of the planet and decided the outcome “wasn’t enough” to introduce into public policy…)

To say that the keto diet has become one of the most popular diets of recent years is a complete understatement. Case in point: There are more than one million searches on Google every month for the keto diet. It’s unique because the fad diet has captured the interest of people who want to lose weight — and there’s no shortage of reported success stories to be found.
A well-balanced keto diet includes enough fat so that you are not hungry after a meal, can go for several hours without eating, and have ample energy. Make sure to increase your intake of fat at the start of your keto journey until your body adapts to using fat and ketones for most of its energy needs. Once you’re fat adapted, let your appetite guide you in cutting back on fat a bit until you reach the point where you can easily maintain the balance between hunger and satiety.
But wait, there’s one loophole. Have polycystic ovary syndrome (PCOS)? Then the keto diet may help regulate your periods. “Women with PCOS have high insulin levels, which cause sex hormone imbalances,” notes Yawitz. In a small study published in the journal Nutrition & Metabolism, subjects with PCOS following a ketogenic diet for six months noted improvements in their menstrual cycles — and a small number of women became pregnant, overcoming previous infertility obstacles. “This study was very small, so we can’t make recommendations for all women with PCOS based on its findings,” says Yawitz. “And really, any diet that leads to weight loss should help in PCOS.”
We all already know that the more sensible, healthful way to diet all comes down to doing something that’s sustainable in the long term. And for most, that means eating fewer refined and starchy carbohydrates, and more fruit and vegetables, essential fats, and protein at each meal to improve your health and energy. But it just isn’t as fun or interesting to say, “I’m eating more vegetables and healthy fats!”
Make things yourself. While it’s extremely convenient to buy most things pre-made or pre-cooked, it always adds to the price per pound on items. Try prepping veggies ahead of time instead of buying pre-cut ones. Try making your stew meat from a chuck roast. Or, simply try to make your mayo and salad dressings at home. The simplest of things can work to cut down on your overall grocery shopping.
They have high likelihood of calcium oxalate and uric acid kidney stones–Kidney stones are uncommon in childhood, yet these kids commonly have kidney stones. The risk in an adult on a prolonged ketogenic effort is therefore high, also. Kidney stones are not benign–they are painful and can occasionally result in kidney damage (increased creatinine, urinary tract infections, etc.)
ME: It helps by removing carbs and forcing the body to rely on fat for fuel. This sort of primes the body for using stored body fat for fuel. It also gets hormones under control, especially hunger hormones like leptin and grehlin. It works because it is a lifestyle, not a fad diet. People can stick with it because they feel so good, aren’t hungry and don’t have cravings anymore.
Weight loss often means feeling hungrier and fighting off more cravings, but that doesn’t always seem to be the case when you go keto. People report less hunger and a diminished desire to eat after adopting a ketogenic diet, according to an analysis of 26 studies. Experts don’t fully understand why, but it’s thought that very low carb diets could suppress the production of hunger hormones like ghrelin.
Where is the science? And if insolin intolerance is a diabetic problem why keep trying to regulate insolin? The stuff isn’t working because your patients are not getting better just deteriorating slower while you make more money keeping them on drugs!!!!! Your hole point is ketosis is bad cause they don’t have to see you after they adjust off the medication that keeps them having to see people like you!!! I have been eating keto for 6 months and feel amazing!!! These people are twisting the truth to keep you sick for there own pockets!!!!!!
Here’s why. All of these effects take time, but a reasonable explanation as to why the keto diet leads to rapid weight loss is due to the loss of water weight. One of the concerns with the keto diet is the loss of muscle mass and the depletion of glycogen stores. Glycogen, which stores our glucose, also stores water, so when stores are depleted, we flush out excess water. In other words, that rapid weight loss isn’t fat, it’s just water.
Hey Edwin, I personally have been following one for years with no issues. I cycle out once every 1-2 weeks with a higher carb day using low glycemic carb sources like root vegetables. One of the keys for me has been keeping it simple and finding ways to use staple ingredients (such as avocados and coconut products) to make a variety of recipes.Check out this article for some examples https://drjockers.com/ketogenic-avocado-recipes/
Keto is often suggested for children who suffer from certain disorders (like Lennox-Gastaut syndrome or Rett syndrome) and don’t respond to seizure medication, according to the Epilepsy Foundation. (1) They note that keto can decrease the number of seizures these children have by half, with 10 to 15 percent becoming seizure-free. In other cases, it may also help patients reduce the dose of their medication.
The keto diet is an extremely effective way to lose weight over a short period of time—even better, according to some research, than low-calorie and low-fat diets. There a few reasons for this: When you’re in ketosis, your body stores less fat. Dieters feel fuller for longer, partly because of the rich food they’re eating, and partly because ketosis changes your hunger hormone levels.
There are people who say that keto helps your athletic performance, and those who say it hurts it. "The literature is mixed on how an ultra low-carbohydrate diet like the keto diet affects athletic performance," says Grant Cox, C.S.C.S., head coach at Iron Tribe Fitness. But one thing is pretty clear: "A lot of it points to consistent decreases when athletes are looking for maximal power output (in weightlifting, vertical jumps, sprinting, etc.). Along the same lines, you'd be hard-pressed to put on weight and strength on such a low carbohydrate diet," he says.
If you experience symptoms like fatigue, intense hunger and cravings, light-headedness, or heart palpitations, this may be a sign your blood sugar has dropped too low. Use a blood glucose monitor to track your body’s response to the diet change and make sure your body is adapting properly. If necessary consult your physician for necessary medication changes.
One of the most basic and most profound benefits of a ketogenic diet is that it drastically lowers inflammation (1). This is mainly due to the reduced amount of free radical production that occurs when burning ketones for energy instead of glucose. Less inflammation allows for more energy production and an overall more efficiently functioning body. This allows for a heightened ability of the body to heal in many different aspects.
Registered dietitian Julie Stefanski is based in York and has specialized in the ketogenic diet for more than a decade. She also advocates for anyone starting keto, especially individuals who have not seen a doctor in more than a year, to first see a physician and/or registered dietitian to have their lab work checked and monitored. She also notes there are certain medications that cannot be used while on a ketogenic diet.
Sleep improvements are a bit more of a mystery. Studies have shown that ketogenic dieting improves sleep by decreasing REM and increasing slow-wave sleep patterns. While the exact mechanism is unclear, it likely is related to the complex biochemical shifts involving the brain’s use of ketones for energy combined with other body tissues directly burning fat.
Otherwise in a nutshell ketosis can be defined as a “metabolic state that happens when you consume a very low carb, moderate protein, high fat diet (or fast for extended periods) that causes your body to switch from using glucose as it’s primary source of fuel, to running off ketones. Ketones themselves are produced when the body burns fat, and they’re primarily used as an alternative fuel source when glucose isn’t available.” (Keto Clarity)
Ketogenic diet for diabetics is a highly controversial topic, but we will break down everything here for you! As a Certified Diabetes Educator (CDE), I have to tell you from the start I will have a biased view here. Sorry, but I feel that I need to be completely honest right up front! I will however, present all the evidence that is available currently on the subject.
so I won’t repeat it all here. The original study that claimed calcium supplements caused heart disease was widely publicized when it came out but unless you had a subscription to the British Medical Journal you wouldn’t be aware of the serious objections published in subsequent issues. In particular, Lappe & Heaney reported the complete opposite result – calcium supplementation REDUCED heart disease versus placebo.
Having said that, there are also studies suggesting that long term carbohydrate restriction diets (aka. the keto diet) may result in fast short term weight loss but people gain it all back in the long term. An RCT put 63 individuals on a low-fat diet or a low carb diet, and the study found the low carb dieters lost more weight compared to the low fat group by month 3 and 6, but that the weight loss evened out by month 12. This was confirmed by a Meta-analysis which found that while low-carbers lost more weight than low-fat dieters but the differences disappeared by the one year mark.
The data presented in the present study showed that a ketogenic diet acted as a natural therapy for weight reduction in obese patients. This is a unique study monitoring the effect of a ketogenic diet for 24 weeks. There was a significant decrease in the level of triglycerides, total cholesterol, LDL cholesterol and glucose, and a significant increase in the level of HDL cholesterol in the patients. The side effects of drugs commonly used for the reduction of body weight in such patients were not observed in patients who were on the ketogenic diet. Therefore, these results indicate that the administration of a ketogenic diet for a relatively long period of time is safe. Further studies elucidating the molecular mechanisms of a ketogenic diet are in progress in our laboratory. These studies will open new avenues into the potential therapeutic uses of a ketogenic diet and ketone bodies.
The popular low-carb diets (such as Atkins or Paleo) modify a true keto diet. But they come with the same risks if you overdo it on fats and proteins and lay off the carbs. So why do people follow the diets? "They're everywhere, and people hear anecdotally that they work," McManus says. Theories about short-term low-carb diet success include lower appetite because fat burns slower than carbs. "But again, we don't know about the long term," she says. "And eating a restrictive diet, no matter what the plan, is difficult to sustain. Once you resume a normal diet, the weight will likely return."
You increase your production of these ketones through a process called ketosis. To get and stay in ketosis, you increase your dietary fat intake while modifying protein and dramatically limiting carbohydrate consumption, and you incorporate intermittent fasting. Human adults have little need for dietary carbohydrates, and reducing intake to shift into mild ketosis can provide dramatic benefits. (5)
A huge concern with the keto diet is the maintenance and potential loss of muscle mass. Many people will just think: hey, dummy, then just eat more protein. However, some research has shown that even if your protein intake remains constant, a low carb diet may promote muscle loss. A study from the Netherlands confirmed these findings. In the study, participants were given three diets (high carb, moderate carb, low carb) and moderate protein. The study found that those following a low carb diet experienced increased muscle breakdown. This is because when we eat carbohydrates, we produce insulin which promotes muscle growth. This is why athletes depend on carbohydrates (along with protein) to fuel their performance. When we eat carbs, the insulin release “unlocks” our muscles to let the protein in so it can do its job at building our muscles. So, when we skip the carbs all together, muscle glycogen stores get depleted, we lose out on those muscle building opportunities. Forget about high intensity training. A depleted glycogen store also means our workouts will suffer because we just don’t have enough oil left in the tank. This was a again suggested in the recent review looking at many ketogenic studies. The studies found that there was greater lean body mass loss in the ketogenic groups compared to the other diets being studied.
Prior to the advent of exogenous insulin for the treatment of diabetes mellitus in the 1920's, the mainstay of therapy was dietary modification. Diet recommendations in that era were aimed at controlling glycemia (actually, glycosuria) and were dramatically different from current low-fat, high-carbohydrate dietary recommendations for patients with diabetes [1,2]. For example, the Dr. Elliot Joslin Diabetic Diet in 1923 consisted of "meats, poultry, game, fish, clear soups, gelatin, eggs, butter, olive oil, coffee, tea" and contained approximately 5% of energy from carbohydrates, 20% from protein, and 75% from fat . A similar diet was advocated by Dr. Frederick Allen of the same era .
What is the keto diet? Rather than relying on counting calories, limiting portion sizes, resorting to extreme exercise or requiring lots of willpower, this low-carb diet takes an entirely different approach to weight loss and health improvements. It works because it changes the very “fuel source” that the body uses to stay energized: namely, from burning glucose (or sugar) to dietary fat, courtesy of keto diet recipes and the keto diet food list items, including high-fat, low-carb foods.
So my question to all of you is: why do most people trying to improve their health appear to not care at all about how their food choices impact the earth and the future of all our children? (Not to mention the horrific conditions that the great great majority of animals bred for food endure?) Is it because you have not been told or do not believe how bad it is (our society has many many who are in total denial about global warning, for instance), or is it because you truly don’t care?
I have serious doubts that eliminating an entire food group is healthy. What’s not being considered is that perhaps there is something in the type of carbohydrates that many people consume in the U.S. that is unhealthy, and not necessarily that all carbohydrates are bad for you. Eliminating these bad carbohydrates might work because you’re actually eliminated a huge source of heavy metal poisoning. Research done by Renee Dufault of the Food Ingredient and Health Research institute strongly suggest that foods laden with preservatives and mercury-laced processed food additives have a strong causal effect on health conditions ranging from ADHD to diabetes. If you are eating processed foods in the U.S., you’re getting a steady diet of heavy metal poisoning from the preservatives, pesticides, and concentrations of mercury in the U.S. food supply. If “food” can sit on a shelf for long periods of time without spoiling, there’s some kind of preservative in it that just might eventually kill you by triggering whatever dis-ease you are genetically predisposed to acquiring. You can read more about her research in her book _Unsafe At Any Meal:What the FDA Does Not Want You To Know About the Foods You Eat_. There is a free tutorial to help you apply what you’ll learn in the book on this web site: http://www.foodingredient.info I wish someone with the money to do more research would find out if its the carbohydrates that are not good for you, or the chemically-laden carbohydrates and beverages that U.S. Americans ingest that are the real culprit.
Either there are very few participants in the studies, they don’t have an even number of males vs. females, or they don’t last but a few months. One study only looked at 28 people; only 21 completed the study and 20 of these participants were men. On top of this, they were only followed for 16 weeks. Okay, so we see that 20 men can limit their carbohydrates severely for 4 months and lose weight which automatically makes their A1c come down. Great! So, the real question is, how long can these 20 men stay on this diet for the rest of their lives? How long would you like to go without eating any fresh fruit? I’m craving some now, so I’m taking a break to go grab a snack now!

Why is intermittent fasting beneficial for women, especially if they’re in perimenopause or menopause? Fasting allows the body to take a break from digestive functions and instead to focus on essential repair work and reaping the many other benefits of rest. In other words, when fasting, the body’s energy resources go towards restorative work (like repairing tissue and balancing hormones) rather than digestive processes like producing stomach acid to break down food.
Keto decreases inflammation and improves brain function — so much so that Alzheimer’s patients who switch to a keto diet actually begin to recover their brain function, which up until now was unheard of. So there’s that. (Dale Bredesen and Mark Hyman have discussed these on the Bulletproof Radio podcast. Check out Dale’s episode here, and Mark’s here.)
Using the Bulletproof Diet, including Brain Octane Oil every day for long periods of time, and eating carbohydrates some of the time but not always, avoiding inflammatory foods, and using Bulletproof Intermittent Fasting, I was able to recently test with perfect insulin sensitivity — I scored a one on a scale of 1 to 120 (see my numbers below). I also had above average glucose tolerance. That’s metabolic flexibility by the numbers!
Two years in and I am this exact same story. I do agree that if one is not insulin resistant or diabetic and has normal insulin response there are other less restrictive diets that will work. I would also add that people fail and drop out of almost EVERY diet program for one reason or another so that argument is null and void. I am under a doctor’s care and am healthier than I have been in years. My only dietary “sin” is artificial sweeteners and I am not looking back! I have not cheated at all on high carb foods and am rarely even tempted. It is doable if your motivation is there and you have support which is true for any kind of life altering decision.
Type 2 diabetes is not a chronic and progressive disease if one removes the offending factors from their diet, namely sugar, flour and seed oils. This is imperative because it accomplishes two things; it removes the factors causing and exacerbating the disease, as well as replace them with nourishing foods that also regulate appetite. With nourishing food, a stable appetite and having removed the disease factors, this disease will not progress but regress.
The crazy thing is it is not hard, if it matters. Sure I can see it being hard for someone who does it to lose weight, then when they get closer to their ideal, they want to have treats, etc. Well, for a type one diabetic there’s no end in sight, this is it, and it’s a relatively complication free life (many people reverse their complications when they bring their A1C down to normal) vs. one with inevitable complications. So, perhaps it was too hard for you after a year (you didn’t say, but I assume you are not a type one diabetic), but that is a choice you can make. Not I.
Hey Marcy! Simply have one higher carb day per week where you consume healthy carb sources like fresh fruit, sweet potatoes, or white rice cooked in coconut oil! Saturday is usually a great day for this! Start with just one higher carb meal on Saturday for about a month and see how that works!
