Also, diabetics should not undertake the diet without medical supervision. “Trying a ketogenic diet has the power to drastically and quickly lower blood glucose levels,” says Santos-Prowse. “If a person with diabetes is taking blood glucose-lowering medications, their doctor needs to be on board to help with adjusting or stopping the medications as needed.”

It is generally believed that high fat diets may lead to the development of obesity and several other diseases such as coronary artery disease, diabetes and cancer. This view, however, is based on studies carried out in animals that were given a high fat diet rich in polyunsaturated fatty acids. In contrast, our laboratory has recently shown that a ketogenic diet modified the risk factors for heart disease in obese patients (12).
For me, I chose to become a CDE because I had worked as a Registered Nurse first on a medical unit, then in a Medical ICU. These are the units where most of the people with diabetes are, so I had seen every horrific complication that diabetes can cause. When I had a chance to become a Diabetes Educator…to actually help PREVENT some of those horrible complications…I jumped at the chance!
There are many physiological reasons for eating enough carbohydrates throughout the waking hours to maintain a steady blood glucose level…a couple of important reasons are to minimize the hepatic release of glucose (from the liver) and to help prevent hypoglycemia which can be very dangerous and lead to hypoglycemic unawareness over a short period of time. Each person is different of course..if you aren’t taking insulin, or pills that lower your blood glucose levels, you may not have to worry about low blood sugars. The reality is, most people with diabetes do; it can be very dangerous for some to not get enough carbohydrates at each meal.
Another earlier study published in the journal, Nutrition and Metabolism, finds that both a low-glycemic index, reduced-calorie diet and a low-carbohydrate, ketogenic diet can improve glycemic control, encourage weight loss, and reduce or eliminate the need for diabetic medication over a 24-week period with the lower carbohydrate keto diet being “most effective for improving glycemic control.”
In some ways, it’s similar to the Atkins diet, which similarly boosts the body’s fat-burning abilities through eating only low-carb foods, along with getting rid of foods high in carbs and sugar. Removing glucose from carbohydrate foods will cause the body to burn fat for energy instead. The major differences between the classic keto and the Atkins diet is the former emphasizes healthier keto fats, less overall protein and no processed meat (such as bacon) while having more research to back up its efficacy.
In 2009, Drs. Eric Westman and Bryan Kraft published a case study and a review of the literature for a 70-year-old woman with life-long schizophrenia. Diagnosed at age 17, she had experienced daily visual and auditory hallucinations (skeletons that urged her to hurt herself) since the age of 7. She also had obesity, sleep apnea, hypertension, and gastro-esophageal reflux disease (GERD) among a number of other health issues. After only 8 days on the ketogenic diet, the voices and hallucinations stopped. At the time of publication she had continued the ketogenic diet for more than a year, with no return of hallucinations, and had lost more than 10 kilograms (22 lbs).
First – let’s admit that there are several different types of diets that produce dramatic improvements in weight loss and diabetes. The vegan diet is one of them (and one which also reduces risk in most other diseases better than the others) – but it is by unquestionably by far the very best diet for the environment and the survival of the planet. High protein (high meat and/or dairy) diets are absolutely TERRIBLE for the environment and are not sustainable in any way. A vegetable diet will END world hunger because we DO have enough earth to grow enough vegetables for everyone and we definitely do NOT have enough earth for meat eaters even at current levels.

Obesity is one of the principle risk factors for diabetes and following a ketogenic diet has been shown to help with weight loss. According to scientific article published in 2014, “A period of low carbohydrate ketogenic diet may help to control hunger and may improve fat oxidative metabolism and therefore reduce body weight.” Many prediabetics struggle with being overweight so a keto diet can help promote weight loss, which can help to decrease the chances of developing full blown diabetes.


By cutting carbs, you’ll also cut sugar and simple, refined carbohydrates, which means a steadier supply of energy. (No more sugar highs and crashes!) Once their bodies are used to the diet, “The first thing people report is, ‘Oh my gosh, I have this steady energy and I don’t have the need to snack at 3 p.m. because my energy is waning,’” Nisevich Bede says. Research published in January 2015 in the journal Obesity Review showed that the keto diet may lead to fewer hunger pangs and a lower desire to eat. (3)

Walking, stretching, or doing gentle yoga or other mind-body exercise should be fine and may even help you feel better. But when your body is already under stress from trying to adapt to a new fuel system, don’t place an additional burden on it by attempting any type of strenuous workout. Take it easy for the first few weeks and then slowly increase your exercise intensity.

The diet calls for consuming high amounts of fat, a moderate amount of protein, and a very limited amount of carbs. It’s usually broken down to 75, 20, and 5 percent of your daily calories, respectively, says Pamela Nisevich Bede, RD, a dietitian with Abbott’s EAS Sports Nutrition in Columbus, Ohio. Compare that with the typical American diet — which is usually 50 to 65 percent carbs — and it’s safe to say this is a completely different way of eating, Nisevich Bede says.
The ketogenic diet is a high-fat, low-carbohydrate, and moderate-protein diet that has been proved to be an effective treatment among patients with epileptic conditions such as glucose transporter 1 deficiency, pyruvate dehydrogenase deficiency, tuberous sclerosis complex, Rett syndrome, Dravet syndrome, and specific mitochondrial disorders (1, 2).
The longer you’re in ketosis, the more fat you burn. Unfortunately, you may also start to lose muscle tissue, too. While protein is considered the powerhouse muscle builder, your muscles need carbs for adequate formation and maintenance. Without those carbs, your body may start breaking down muscle. “Since your body starts to eat away at muscles as it enters ketosis, your heart, being a muscle, may also be damaged in the process,” Derocha says.

The research on ketogenic diets also suggests you'll need to take a multivitamin to get enough minerals, calcium and vitamin D — most of which are readily available in plant-based foods. One keto-specific example: Not getting enough selenium, an immune-boosting antioxidant found in plant foods, can cause cardiomyopathy, a hardening of the heart muscle leading to heart failure.
Ketones are more beneficial to the brain than glucose is.  This is great news for patients with Type 1 Diabetes, because it will not affect the brain function when you are running low in glucose. Ketosis prevent raising blood glucose levels, since you are not introducing large amounts of carbs into your system. They help in stimulating the growth of healthy brain cells. 

🙌🙌 thank you for some great info! USC just had an article about Keto, saying they don’t know the impact on bone health. So I’m not sure why all these articles are written without the documentation to prove the claims. We all know too much calcium supplementation can cause problems but every Dr wants you to supplement calcium. Most people could do a lot worse than doing Keto! The SAD will cause more problems for you than eating whole, unprocessed Keto food! Sugar seems to be the real issue along with aspartame and stressful living.
Use Exogenous Ketones: Exogenous ketones are a fantastic way to train the body to use ketones for fuel before our body is good at creating ketones.  They also buffer hypoglycemic responses by providing ketones the body can use for energy rather than having a significant stress response when blood sugar drops.  A great exogenous ketone product that also has adaptogens and electrolytes is Keto Edge

Controlling your blood sugar levels helps you control your cravings, Dr. Burrows says. “When we are not on a sugar roller coaster from processed carbohydrates, most people make better food choices because they are not looking for their next hit of food,” she says. You may also find you’re able to go longer periods without eating, he says. Intermittent fasting is a common practice among dieters who’ve been eating keto for a while. Learn how one woman totally kicked her sugar habit by trying the keto diet.
"If you're going to do keto, there's a better and a worse way to do it," registered dietician Kim Yawitz told Everyday Health. "Loading your plate with meats, and especially processed meats, may increase your risk for kidney stones and gout... High intake of animal proteins makes your urine more acidic and increases calcium and uric acid levels. This combination makes you more susceptible to kidney stones, while high uric acid can increase your risk for gout."
Restricting carbohydrates.  Studies show that after three or four days without carbohydrate consumption, your body starts tapping its fat storage also known as ketosis. You’ll want to stay between 25–35 grams of carbs to get into ketosis, and that requires bucking mainstream, carb-heavy, and supposedly nutrient-rich foods like fruit and grains. There are good carbs you can eat that will help you stay in ketosis. Be sure to look over these more keto diet friendly fruit options.
From an outpatient clinic, we recruited 28 overweight participants with type 2 diabetes for a 16-week single-arm pilot diet intervention trial. We provided LCKD counseling, with an initial goal of <20 g carbohydrate/day, while reducing diabetes medication dosages at diet initiation. Participants returned every other week for measurements, counseling, and further medication adjustment. The primary outcome was hemoglobin A1c.

Although the exact role of the keto diet in mental and brain disorders is unclear, there has been proof of its efficacy in patients with schizophrenia. And, to boot, it works to reverse many conditions that develop as a side effect of conventional medications for brain disorders, like weight gain, type 2 diabetes and cardiovascular risks. More research is needed to understand the role of the ketogenic diet in treating or improving schizophrenia, as the current available studies are either animal studies or case studies, but the benefits of a low carbohydrate, high-fat diet in neurology is promising.
It has been found that a sugary diet is the root cause of various chronic diseases of the body. A recent study (35) showed that sugar can accelerate aging. Several recent studies (36,37) have pointed to the fact that a diet with a high glycemic load is independently associated with the development of cardiovascular diseases, type II diabetes and certain forms of cancer. Glycemic load refers to a diet of different foods that have a high glycemic index. Glycemic index is a measure of the elevation of glucose levels following the ingestion of a carbohydrate. The classification of a carbohydrate based on its glycemic index provided a better predictor of risk for coronary artery diseases than the traditional method of classification of carbohydrate into simple or complex forms (38). In other studies (38–46), it was shown that the risk of dietary glycemic load from refined carbohydrates was independent of other known risk factors for coronary diseases.

Ketogenic diets are not for everyone. There are some people who should be very careful with the ketogenic diet, or at least should not do it without medical supervision. While I understand not many mainstream doctors will be well versed in the ketogenic diet, there are online services that can pair you with a primary care doctor who understands keto in detail.
The longer you’re in ketosis, the more fat you burn. Unfortunately, you may also start to lose muscle tissue, too. While protein is considered the powerhouse muscle builder, your muscles need carbs for adequate formation and maintenance. Without those carbs, your body may start breaking down muscle. “Since your body starts to eat away at muscles as it enters ketosis, your heart, being a muscle, may also be damaged in the process,” Derocha says.
Brain fog and a lack of focus can be caused by having too much glutamate and very little GABA. This will happen if your brain has to use glutamate and glutamic acid for fuel, which leaves little left over to be processed into GABA. By giving the brain another form of energy when you break down ketones, you’re able to balance out the neurotransmitter production.
In general, men tend to do better on a long term ketogenic diet than women do. From my own research and experimentation, women can follow a keto diet, but with some adaptions. Most women will do well with a cyclical ketogenic diet when they stay on ketogenic diet most of the time and eat starchy carbohydrates occasionally to spike calories and carbs.
Earlier in this article, I briefly mentioned how consuming too much sugar can impair brain function and cause plaque build up in the brain. Many studies on Alzheimer’s disease patients agree with the biochemistry as well. In fact, A group of scientists reviewed the literature and concluded that “high carbohydrate intake worsens cognitive performance and behavior in patients with Alzheimer’s disease.” This means that eating more carbohydrates cause more problems in the brain. Will the opposite (eating fewer carbs) improve brain function?
In 2013, researchers published a case study of two women with bipolar II who ate long-term ketogenic diets, one for two years and the other for three years. The authors reported that both “experienced mood stabilization that exceeded that achieved with medication; experienced a significant subjective improvement that was distinctly related to ketosis; and tolerated the diet well.” They noted, too, that “there were no significant adverse effects in either case” and that the two cases “demonstrate that the ketogenic diet is a potentially sustainable option for mood stabilization in type II bipolar illness.” .

I would just like to share with you that my patients are HORRIFIED if their physicians ask them to cut out “everything white” in their diet. This is what some doctors ask for…essentially asking for the Ketogenic diet and most of my patients are in shock! Not only would I never want to skip a year of my birthday cake, but I wouldn’t ask my patients to either! One slice of cake is certainly not going to harm anyone with diabetes and hopefully you know enough about carbohydrates and their short term effect on BG levels to know this too! I am not a Registered Dietitian, so I couldn’t speak to this diet in regard to children with epilepsy. Are you a Neuro RN? TheDiabetesCouncil did just post another article where 25 Registered Dieticians weighed in regarding the Ketogenic Diet, so I would encourage you all to check that out!
Lazy keto diet: Last but not least, the Lazy keto diet often gets confused with dirty keto … but they’re different, as the “lazy” refers to simply not carefully tracking the fat and protein macros (or calories, for that matter). Meanwhile, the one aspect that remains strict? Not eating over 20 net carb grams per day. Some people find this version less intimidating to start with or end with … but I will caution that your results will be less impressive.

Additionally, you may find it difficult to eat adequate calories on a daily basis because fat is so filling. Some people even opt to fast for several hours each day. While this may help with weight loss, your body needs those calories for proper maintenance. Without them, it may turn to burning muscle for energy, and that can accelerate muscle loss.

Good article. A friend at work is stating this diet and of course being new at it, he is quite the Zealot. I have been into nutrition and exercise for over 40 years (57 years old now). I have tried s few different eating philosophies (I never use the word the word diet. Negative connotation and dieting isn’t good the way most practice it.). Eating Keto style and the logic behind it aren’t too different than some others. And you pointed out many of the misconceptions about cholesterol and triglycerides ect. For about the last 20 plus years I have pretty much followed a “Zone” type diet. 40% carbs, 30% fat, 30% protein. And I always get weird looks at the 30% fat part. Well, I’m 57 with 7% body fat. Not bad for and old guy. I work out and I supplement with protein as I lift weights. It’s worked well. The ratios may be different, but the emphasis on vegetable carbs and good fats are the key to either way to eat. There were only a couple things that kinda struck me as something that made me go hmmmmm. Using the Inuit people isn’t a good example really. They have evolved some different physical features over hundreds of years than we have. And there is no evidence if ketosis occurring in examination. And somehow when you mention eating large amounts of animal fat, just hit me as counterintuitive. It’s a much different fat than an avocado. Finally, and this is just me, I love fruit. True it’s probably less efficient, but its good, sweet, and beats the hell outta donuts for your health. It fulfills the reward need many of us have. I also feel if God put it on the earth naturally, it’s got a place in our food source. I’ve had a philosophy about excersise that’s served me well. What’s the best exercise? The one that you’ll do regularly. Get up and move and find out what works for your own body. It applies to good too. If you feel deprived or for various reasons can’t stay on the supposed best food program, what good is it? But if you stay with more natural and Balanced foods that usually leads to more energy then more and regular excerise. Check in. It looks like it’s been 2 years since you wrote this. I’d live to hear how your doing.
Regarding keto diets specifically, studies have proven this method to be more effective than moderate protein diets in lowering blood glucose, promoting weight loss and lowering HbA1c in patients with Type 2 diabetes. A growing number of clinicians now agree that low-carb diets can effectively treat this disease. The fact remains: these diets remain controversial and contradict dietary guidelines, so they are not very often discussed or recommended in the clinical setting.
The fact is, the stress that you will bring on yourself from constantly restricting every single thing you put in your mouth is far more detrimental to your health. Remember, moderation is the key! You can count your carbohydrates and follow a sensible low carbohydrate diet to control your blood glucose and your weight. Exercise will always be the key component to add that contributes to added weight loss.
It’s the same with a keto way of eating: there is a ton of research and studies out there, and we KNOW that it works. Sure, more studies will come, and the new information will help us refine it, and we will learn how it specifically affects certain individuals in different ways…but the truth about the basics of it are all there, in the open, for all to see.
At the core of the classic keto diet is severely restricting intake of all or most foods with sugar and starch (carbohydrates). These foods are broken down into sugar (insulin and glucose) in our blood once we eat them, and if these levels become too high, extra calories are much more easily stored as body fat and results in unwanted weight gain. However, when glucose levels are cut off due to low-carb intake, the body starts to burn fat instead and produces ketones that can be measured in the blood (using urine strips, for example).
Some of us experience a rise in BG that’s hard to manage when trying Keto. This is one of the reasons why keto did not work out for me (plus weight gain and feeling lousy). That being said, there could be a lot of other reasons why he’s running high, so I’d highly recommend you work with a medical professional and dietitian if you decide to continue down this path. And if your doctor isn’t supporting you, find one that will.
Truly Dr. Colbert is also a reputable source for more thorough science and modification of previous Keto extremes. The statements about Keto diets with dairy everyday are not true…I am a 66 year old professional (University trained) and have found medical people often very unknowledgable or partially knowledgeable which may be worse. I ask you Abbey to dig deeper…meet Dr. Colbert-not a quack and more in depth than your overview. Personally I am finding switch to more green’s and low glycemic vegetables and fruits with healthy fats, occasional dairy and healthy protein; a way of life that is helping our whole family. Please watch The Magic Pill…the help for family’s caught in old thinking from poor science (ie. Alex Keys) and with autism etc. and so much modern disease is in itself, motivation to search out more truth.

I am a holistic health coach and focus on women and keto primarily. I have thought of checking out your box. After running across this article {which I shared with all my current keto groups I am coaching!} I am definitely going to sign up! AMAZING article! I am all about digging into as much good science and research as I can to help people better understand health in general and particularly keto. This article is right up my ally! Thank you, thank you, thank you! ❤️


The ADA has recommended since 2013 we use our best clinical judgement in recommending a low carbohydrate diet for people with diabetes, recognizing it needs to be individualized. 60-75 grams is the carbohydrate amount I would give to a very tall, large boned man or perhaps an active teen or young adult. I would never recommend that many carbohydrates for an average size man who was trying to lose weight; he would get 45-60 grams of carbohydrates per meal and 15-30 grams for snacks. A women trying to lose weight would get 30-45 grams of carbohydrates per meal and 15 grams for snacks.
Researchers believe that genetics likely plays a role here, making some people more susceptible to liver problems when following low-carb, high-fat diets. Is the keto diet bad for your kidneys? According to an article released by Harvard Medical School, “Patients with kidney disease need to be cautious because this diet could worsen their condition.”
I, too, am finding the keto diet to be beneficial. My weight is moving down. My recent A1c was 5.7. I am consistently below 90 each morning when I check my blood. I am learning to adapt my cooking to the needs of maintaining this way of eating. I have incorporated walking because now I FEEL like it. I don’t feel deprived. I feel empowered. No medications for diabetes!
Roxy, I started at 283 in February 2018. I am now 212 with the hope to make 100lbs lost by Feb 2019. KETO is a life choice and comes with changes that have to be made! My mantra at difficult times in the beginning was to be different i must do different! Also most modern foods pizza and tacos can be adapted to keto way of eating. Just takes research and a little planning. I have tacos weekly!

Once the medical community acknowledged the keto diet’s effectiveness in reducing seizure episodes, they decided to look further and study its impact on neurological diseases in general. Neurological diseases share a common problem – a deficiency in energy production. Ketones provide that energy for normal brain cell metabolism, and may even be a more efficient   when the body is in starvation mode. When patients were put on the keto diet, the number of mitochondria (energy powerhouse) in brain cells increased. Ketones may also act as an antioxidant by inhibiting the formation of reactive oxidant species, which is why they may have promising effects in the treatment of certain cancers in conjunction with chemotherapy.
Such great info. Husband has been seizure free 11 months. Was having 2-3 per month. Learning new and great awesome recipes. There is one side affect, I have lost 40#, our daughter, has lost 70#. However, my husband has not lost any weight. His body was at the correct weight before we started. My goal is not weight loss, that’s just lagniappe, my goal is better health. This is such an awesome journey.
Ketosis is different, because, when in the state of ketosis, the brain will prefer ketones over glucose. For the dieter this is good! The body will not have to break down protein for energy. In turn the body will be forced to use its fat reserves, a.k.a. your love handles, for its energy. This is why a low-carb diet is such a good method of dieting.
I suggest you or other readers who are not familiar with Dr Wahl's work and research into autoimmune disease and brain biology get a copy of 'The Wahl's Protocol'. Medicine and nutrition are ever-changing sciences and sadly we can't rely on our standard medical practioners (or registered dieticians) to share important research we should all be able to access.
No one is trying to diminish your success, but it does not work for everyone, and studies show it can have long term negative effects on your overall health. If you look at the Meta-analysis it shows a calorie restricted diet and Keto for 12 weeks had the same weight loss. There are also many studies that suggest looking back at people after one year those on a calorie restricted diet kept more of their weight off. The only one it does better than is just a low fat diet, which Dieticians stopped suggesting long ago. And as Health Care professionals we read the “REAL SCIENCE” not the internet articles, You Tube, Blog, book writers. One of the books written about it by Dr. Jason Fung. Have you looked him up on PUBMED? He has not written one article published in a real medical journal to be such an expert. It is not magic, it is not a cure. If you like the diet and it does not mess up your cholesterol then so be it but promoting it to others not knowing their medical history can be dangerous. What people don’t realize is that for year’s we have known that if you lose 7-10% of your own body weight your blood sugars will improve, cholesterol, and blood pressure. But you don’t have to do the fasting and put more burden on your Liver or potentially increase your risk for cardiac problems eating such high fat. If you do high fat at least do plant fats and not animal fats. But of course everyone is happy with your success but just keep a tab on your lab work.
Hypothyroid Related Issues. Thyroid hormones and cholesterol levels are intimately linked. When our thyroid hormone levels are low, LDL receptors will be less active, leading to high cholesterol levels and an increased risk of heart disease. If you have a history of hypothyroid issues, you may be struggling with unhealthy cholesterol levels — and the keto diet can make them even worse. However, for those of you who are being treated for your hypothyroid condition or who have an autoimmune thyroid condition, you may be able to follow the keto diet without any problems. In fact, many keto dieters with autoimmune thyroid conditions have found that the keto way of eating improves their quality of life more than any other diet.

As Mark Sisson puts it, doing a keto reset restores our “factory settings,” which is our flexibility to alternate between different types of fuels and stored fats for energy, depending on what’s available. This flexibility has allowed humans to thrive for millions of years because hunter-gatherers didn’t always have access to constant abundance and variety of foods that we have today.
Diabetes is actually a metabolic problem. It’s characterized by the hormone insulin no longer exerting its important actions appropriately. Your cells and tissues don’t ‘hear it knocking’ so to speak. So you produce more and more insulin, which eventually fatigues your pancreas. This deluge of insulin (hyperinsulinemia) you now find yourself bathing in also causes your fat stores to release fat inappropriately. This ultimately swamps your liver with excess fat (energy). To reduce the excess energy, your liver handles starts frantically producing and pumping out lots of blood glucose. This task (gluconeogenesis) is costly and momentarily solves your liver’s crisis of energy excess. The longer-term cost however are serious consequences like high blood sugars, unstable energy levels, damaged tissues (via glycation and ROS), neurodegeneration and worse body composition (with fat usually stored in the wrong places), etc.

Although this may repel people away, it also provides you with a clear sign that you are on your way to reaping all the benefits of keto and ketosis. As your body continues to produce ketones, it will become more efficient at creating and using the energy-shuttling ketone bodies, beta-hydroxybutyrate and acetoacetate, which will help reduce acetone levels and normalize your breath. In the meantime, while your body is adapting to ketosis, make sure you have breath-freshening gum or spray that you can use throughout the day to cover up keto breath (if you have it).


To be clear, most of the hype you’ll hear about how the ketogenic diet can ward off cancer is taking things too far. While there is a fair amount of research regarding cancer, studies have been limited to animals. One review published in Redox Biology highlighted some of them, indicating promising results for colon, gastric, and prostate cancers. Maybe more interesting are the few case studies involving human subjects. Bear in mind, we’re talking about a handful of people. In these cases, implementing a ketogenic diet seemed to halt disease progression.
Although the ketogenic diet has been a source of controversy and debate, one cannot dispute its astounding health benefits. Initially, it was created by specialists at John Hopkins Medical Center, particularly for individuals who have epilepsy. The researchers established that fasting enhanced the number of seizures the patients experienced. Nonetheless, since fasting isn’t an accomplishable purpose nowadays, a diet has been developed that would trick the body into believing it was in that process.
The walking around part is not true in my experience, exercise alone will not help an obese person. I’ve been doing Keto and most things I’ve read have come true, I found this article to be unbiased. I will say this however, I agree I too have been eating many green veggies and the bad stuff I do use I use very little for flavor (like bacon) what I found that is utterly ridiculous on the part of the folks that did the diet rankings was saying Keto was unsustainable. The way I feel from being on Keto is insanely well. I want to keep eating this way! Unsustainable its the only diet I can do intermittent fasting on. I was type 2….
Protein: A typical recommended keto protein intake is between one and 1.5 grams per kilogram of your ideal body weight. To convert pounds to kilograms, divide your ideal weight by 2.2. It’s important to note that Kidney Disease: Improving Global Outcomes (KDIGO) recommends that adults with diabetes limit their protein intake to less than one gram per kilogram of body weight each day and that adults with chronic kidney disease avoid protein intake greater than 1.3 grams per kilogram per day.

It’s also common for people starting the diet to experience flu-like symptoms, such as headaches and fatigue. This side effect is so common that there’s a name for it: the keto flu. “You shed a ton of water weight at first, which can lead to dehydration,” Nisevich Bede explains. This can worsen the symptoms of the keto flu. To counter it, she recommends staying hydrated and loading up on electrolytes through electrolyte tablets.

There have been many attempts at studying the link between type 2 diabetes and the keto diet. In one study, a strict low-carbohydrate diet was administered in obese patients with type 2 diabetes. After 14 days of being on the diet, the glucose levels of participants normalized, their hemoglobin A1C decreased from 7.3% to 6.8% and insulin sensitivity improved by 75%. Some of this study’s limitations include the short duration, the small sample size and the weak control group. In another study, 84 obese patients with type 2 diabetes were randomized to either a low-carbohydrate keto diet or a low-glycemic reduced calorie diet. At the end of the study, both groups experienced improvements in glycemic control however the low carb keto group had greater improvements in hemoglobin A1c and higher HDL levels compared to the low-glycemic group. A more recent 2017 study in the journal of Nutrition and Diabetes found that a low carbohydrate ketogenic diet for 12 months led to greater reductions in HbA1c and body weight. These results suggest that low carbohydrate interventions may be effective at improving glucose control.


OK, so this is the one most people probably actually care about. The great thing about the keto diet is that most dieters report not feeling hungry at all, likely because ketosis tends to suppress the hunger hormone, ghrelin, which helps tame our hangry monster within. So when you combine a satiating diet with the fact that you’re just cutting out a lot of foods, it makes perfect sense then that you’ll lose weight. One meta-analysis found that participants lost more weight on a very low-carb diet (like keto) compared with those on a low-fat diet.


“You can spend two hours in the gym but ruin it with a bad meal,” said Sowers. “Incorporating all the food groups in proportioned sizes throughout the day is the best way to not only lose weight, but to also control appetite. Restaurants are also making it easier to eat healthier with calorie counts on the menu. Now people are able to make mindful choices when they go out to eat.”

Dr. Campos, it is so discouraging to see that you disparage the ketogenic diet based on your assumption that it is very heavy in poor quality processed meats. No diet that relies on processed foods can be viewed as “healthy”. Become better informed by getting up to speed with what Jeff Volek, RD, PhD, calls a “well-formulated ketogenic diet.” Also, learn more about the potential of the diet to slow cancer progression (my specialty). You owe it to your patients who are depending on you for advice. Present them with facts, not opinions.
While the science of nerve signaling and genetic mutations is incredibly complex, it makes sense that a therapy, the ketogenic diet, that has been used successfully in epilepsy for 100 years might be helpful in conditions that share some similar features. Could changing the brain’s fuel, help change the malfunctions in its nerve cell firings and neuron excitability?
This effect can also be demonstrated by researchers at Kraft Foods, published in the American Journal of Clinical Nutrition. For 12 weeks one group ate a low fat, calorie restricted date, and the other ate a low-carb, high-fat diet without restriction… other than low carb of course. After 12 weeks, the low-fat group lost 5.5 pounds and the low-carb group lost 10.8 pounds.
Walking, stretching, or doing gentle yoga or other mind-body exercise should be fine and may even help you feel better. But when your body is already under stress from trying to adapt to a new fuel system, don’t place an additional burden on it by attempting any type of strenuous workout. Take it easy for the first few weeks and then slowly increase your exercise intensity.
If you're healthy and eating a balanced diet, your body controls how much fat it burns, and you don't normally make or use ketones. But when you cut way back on your calories or carbs, your body will switch to ketosis for energy. It can also happen after exercising for a long time and during pregnancy. For people with uncontrolled diabetes, ketosis is a sign of not using enough insulin.
It’s important we distinguish between the process of ketoacidosis seen in type 1 diabetes and this ketosis that so many people on the keto diet are striving for. If someone with diabetes lacks enough insulin and/or does not eat enough carbohydrates, they risk entering a state known as ketoacidosis. For those with uncontrolled diabetes, this can increase the levels of ketones in the blood, increasing the acidity of the blood, and potentially leading to a coma or even death. In ketosis for a healthy individual, the level of ketones in the blood never reaches these crazy high levels so it’s generally safe for the average healthy individual.
Let me introduce myself. My name is Mark Sisson. I’m 63 years young. I live and work in Malibu, California. In a past life I was a professional marathoner and triathlete. Now my life goal is to help 100 million people get healthy. I started this blog in 2006 to empower people to take full responsibility for their own health and enjoyment of life by investigating, discussing, and critically rethinking everything we’ve assumed to be true about health and wellness...
If you are seeking fat loss but do not want to follow a strict ketogenic diet, you will be pleased to know that this study found that the weight loss benefits came purely from a low carb diet – whether it was ketogenic or not. If you need help transiting to a lower carb diet, be sure to download my free diet plan or better yet, be sure to view the most effective way to lose fat and keep it off on this page. 

On keto, I’ve adjusted my basal rates and I barely need to bolus at all. My blood glucose numbers have definitely improved and what I find really extraordinary is that I’m needing about 60% less total daily insulin, than I did before starting keto. What’s even more fascinating to me is seeing a steady straight line across my pump for 6, 12, and even 24 hours – no crazy spikes or dips in my blood sugar.


I suffered through a year on 20 grams of carbs per day and it was the worst year of my life. Yep, I lost weight, but at my current weight of 130 lbs and eating 30 carbs per meal and remaining in a prediabetes state for 15 years, I am healthy AND happy now. None of us know the long term effects of most of what is offered to us…medications, diet drinks, processed foods, restrictive diets. The point I was trying to make was eating healthier, more natural foods will be better in the long run, I believe we all have the common sense to agree on that, even if we can’t agree on how many carbs we will eat!
“The human digestive tract is simply not well designed for digesting grains. The proteins in grain, especially the gluten, are very difficult to digest, even if you don’t have apparent gluten problems. Too much grain, especially of the highly refined kind, is behind many of the cases of food allergies, irritable bowel, chronic indigestion, and yeast overgrowth that I see every day.”

2 days from grains my stomach bloat was gone and I knew at that point everything this article and American diet was a lie. I’ve been on keto for over 16 months. Down 50lbs. In 6 months. I am ripped. Haven’t lost any muscle mass. I eat greens protein and healthy fat. I whole juice to get macros and yes I add watermelon or berries fo palatability purposes. I still eat carbs just healthy choices. I’ve become carb tolerant.. your liver will produce all glucose without ever eating 1 carb. This is biased and poor representation of keto lifestyle. When your starving and no carbs to choke keto will still thrive on either or fuel.
Lots of apps and websites offer keto diet challenges—basically, a blueprint for the keto diet with a fixed starting and ending point (they typically last for a week to a month, though some may be longer). Speaking of apps, plenty of keto-centric ones are right at your fingertips (a.k.a., your smartphone), like the KetoDiet app, which can help you calculate your macros and track your keto diet effectively.
Essentially, the keto diet for beginners works by “tricking” the body into acting as if its fasting (while reaping intermittent fasting benefits), through a strict elimination of glucose that is found in carbohydrate foods. Today the standard keto diet goes by several different names, including the “low-carbohydrate” or “very-low-carbohydrate ketogenic diet”(LCKD or VLCKD for short).
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)
No Pete, this is not true. What you have mentioned is based on the seven country epidemiological study done by Ancel Keys in the 1970s. This entire study was based on flawed science. Ancel Keys cherry picked the data that supported his argument for the foundation for his hypothesis. Although this hypothesis was never backed by scientific evidence the mainstream medical system took it as gospel in creating standards for the health professionals.
Other causes of diarrhea on the keto diet include consuming a diet low in fiber (fiber helps ward off diarrhea by bulking up stool) and eating processed low-carb foods like shakes and bars that may contain sugar alcohols. These sugar alcohols can ferment in the gut and cause gastrointestinal discomfort. Yawitz suggests limiting foods labeled “sugar free” if you’re prone to gas or diarrhea when you eat them. And you may want to gradually adjust your carbs downward and your fats upward. “Also build your diet around [naturally] high-fiber, low-carb foods like avocado and nonstarchy vegetables such as broccoli, cauliflower, and asparagus,” she says. Other keto-friendly ways to get more fiber include chia seeds, almonds, and coconut.
In another study on women, researchers confirmed that the ketogenic diet resulted in favorable changes in LDL particles consistent with lower cardiovascular disease risk. However, the total LDL cholesterol did not change. This is why it is important to test the levels of different LDL particles. Looking at the LDL number itself may be misleading, especially on the ketogenic diet.

What happens is that fats get stored in your body if you do not have enough physical activity every day to break them up. As they get stored, they show in the form of belly fat. As a result of that, you appear obese. To make the body slim, you have to use up the daily fat as soon as you ingest it. Otherwise, it accumulates in the body and makes you obese.


Reduced hunger. Many people experience a marked reduction in hunger on a keto diet. This may be caused by an increased ability of the body to be fueled by its fat stores. Many people feel great when they eat just once or twice a day, and may automatically end up doing a form of intermittent fasting. This saves time and money, while also speeding up weight loss.

Thanks for posting this Edward. While I agree that the thought of a lifetime without any sweets or any grains sounds miserable, it’s even more miserable every time I see a number above 120 on my meter, which is guaranteed to happen every time I eat even a few bites of one of those foods. Yeah, it’s stressful (and cortisol is just as much of a pain as T2D), but I want a better life and a life off of drugs. I was on three orals and two shots of insulin daily.
Just as people can vary dramatically in their response to carbs, I would not be surprised if that’s the case for some people. Might this be another case of copy numbers of AMY1 SNPs? But most people need to assume that WB/Undoctored is not a full-time KD. The goal of the 50g/day, 15g/interval is not for elevated ketone levels; it’s for ideal average and peak blood sugars.
Dementia and Alzheimer’s Disease A small study published in February 2013 in the journal Neurobiology of Aging found that older higher-risk adults on a keto diet experienced better memory functioning after just six weeks. (11) Some experts, like Richard Isaacson, MD, director of the Alzheimer’s Prevention Clinic at Weill Cornell Medicine and NewYork–Presbyterian in New York City, support low-carb diets for patients as one way to delay brain aging and possibly Alzheimer’s disease, the most common form of dementia.
Of course, there are over 160 research papers currently on Pubmed with the words “diabetes” and “ketosis” or “ketogenic” in the title alone. It’s beyond clear that ketogenic dieting is extremely effective for many people with both type I and type II diabetes for all the reasons discussed above related to keeping blood sugar levels and insulin in check.
Ketosis, similarly to fasting or caloric restriction, turns on a group of genes called Sirtuins. When scientists activate Sirtuins in animals, they found that these animals live longer. In addition, Sirtuins can help keep you lean and energetic during the day and sleeping well at night. More research is needed to know if this effect is the same in humans, but evidence seems strong that spending some time in ketosis is beneficial.
Every reduced-calorie diet is catabolic, meaning the diet can cause you to lose muscle. 'This is largely due to the fact that you are consuming less energy, so your body relies on other tissue (i.e., protein) to serve as an energy source. Added to that, some dieters do copious amounts of aerobic exercise when dieting, which can cause further breakdown of muscle. The brain can also call on protein to create more glucose for energy needs—a process called gluconeogenesis.
Early research suggests that the keto diet may slow the growth of cancerous tumors. “Cancer cells have plenty of insulin receptors on them, making them flourish in environments high in blood sugar and insulin,” says Brandon Olin, host of The Deskbound Podcast, which focuses on overcoming the damage of a sedentary lifestyle. “It’s essentially giving cancer cells a source of fuel to feed on and grow.” The research suggests ketone bodies may provide energy for your body without feeding the tumors.
He also told me that I was in horrible shape, that I would need a lot of medication, and that because I was T2, insulin would do nothing for me. I still remember walking out of the building after. I felt like shooting myself. My brother had just gone blind from retinopathy 2 months earlier. There was no hope for me. High numbers were inevitable. Complications were inevitable.
Disagree. I’ve been eating like this for ten months. I still enjoy carbs on the rare occasion but stick to a ketogenic diet most of the time. Ive lost 94lbs. I understand people lose weight in other ways but for me this worked. I eat 10x as many green vegetables as I ever have (at least 2 meals a day). My blood pressure dropped drastically in the first month. My cholesterol, triglycerides and blood sugar all normalized within the first 90 days. I don’t see any reason not to continue. I find this way of eating empowering and not restrictive. Before you call something a fad, because you obviously don’t fully understand this, you ought to read something from people other than the people you agree with. This is the problem I have with dieticians and most doctors. You don’t think for yourselves. You follow whatever the accepted guidelines are and spout them off without ever asking if they are right. It’s easier to stand with the crowd. I get that. But do not use your expertise as a means to criticize real progress. I would think as an expert your would be a proponent of what works! Have you ever been morbidly obese? Do you know what it is like to think your going to die from a heart attack at a young age? Do you know what it’s like to know your going to get type 2 if you can’t overcome your weight? Eating this way got me out of all of that and gave me my life back. Come down from the Ivory tower… Just maybe a little less judgement, a little more open minded

Thank you for your wonderful comments Marcia. To share more about me personally with you all…I am not a completely non-diabetic Certified Diabetes Educator. I found out I had Prediabetes 15 years ago when I became a Diabetes Educator. I tested my own A1c and found it was 5.8%. The incredible news? There have been years when my A1c dropped to a normal level of 5.4%…out of the prediabetes range. My last A1c in May was 5.8%, so I still have Prediabetes 15 years later, but not diabetes, and without any medication, just the sensible diet I’ve discussed and exercise, so I really am living with this. I feel it everyday, I wonder what my A1c is going to be just like you every 6 months when I go to have it drawn.
Of the many benefits of a keto diet, weight loss is often considered No. 1., as it can often be substantial and happen quickly (especially for those who start out very overweight or obese). The 2013 study published in the British Journal of Nutrition found that those following a keto diet “achieved better long-term body weight and cardiovascular risk factor management when compared with individuals assigned to a conventional low-fat diet (i.e. a restricted-energy diet with less than 30 percent of energy from fat).” (2)
Iwould hope to meet a diabetic nurse in the uk who was open minded about keto, but that has not been my experience as a patient. As a nurse speaking to colleagues as an equal and frmy experience has been very different. I have not spoken to one nurse with personal/professional interest in this subject that has said if they were diabetic they would follow the guidance of our health service. All have said they would do keto.
Your article started off well when you began to explore the science behind the diet. However you missed the mark by saying that the reason to stay away is because it’s being done wrong and theorizing that people are doing it because their friends are. Rather you should have explored the proper way to adhere to the diet and then made an informed decision about its benefits or negatives. You cannot start and article with science and end with personal feelings or opinions

There are various ways to practice intermittent fasting on keto, including some that are less likely to trigger side effects like fatigue or cravings. Crescendo fasting gives you a break from fasting throughout your week, but is still very helpful for achieving the benefits of IMF. Dr. Cabeca and other experts, such as Amy Shah, M.D., advise their patients to check their urinary ketone levels (using ketone strips) and to aim for testing positively for ketones about three days per week.

The average person's diet contain about 55% carbohydrates, 30% fat, and 15% protein. On the keto diet, you eat a whole lot more fat, and a lot less carbs: 80% of the diet is comprised of fat, 15% is protein, and a mere 5% of calories come from carbohydrates. For someone on a 1,500-calorie diet, that translates to 19 grams of carbohydrates per day, which is less than what you find in one medium-sized apple.
While there have not been large studies that show the relationship between the ketogenic diet and cancer, we will be publishing a case study about that topic. The author failed to comment that pediatric patients with epilepsy are on the diet for usually about 2 years with no harmful effects. Before the false studies about heart disease and fat, the low carb diet was a respected way to lose weight. Studies into our metabolism show we can use both fat and carbohydrate as fuel. So stepping away from our high carb diet- I am sorry to say that we eat more carbs since the 70s with most of it processed and we now use high fructose corn syrup to sweeten products and we have a wide spread childhood obesity problem. If cholesterol is a concern try plant sterols and stenals to block cholesterol from the receptors in the body. So much more can be said about a keto diet than this article states
