Our body needs some time to get used to ketones being elevated in the blood stream to begin using them effectively and efficiently for cellular energy.  By consuming an exogenous ketone supplement, you get the body adapted to ketones faster and using them as an energy source before the body has built the metabolic machinery to produce its own ketones effectively. 

What about heart health and the keto diet? Previous older schools of nutrition would purport that a diet rich in fats (specifically saturated fats) would be detrimental for heart health, but more recent research suggests that saturated fat is not as bad as previously believed.  There is actually a tiny little bit of evidence that a keto diet may improve triglyceride, HDL and LDL levels. Like here and here. An even more recent study found that a keto diet improved triglyceride, HDL and LDL levels. We’ll definitely have to wait to see how that research unfolds because there is definitely a lot of competing elements at play.
When Steve contacted TheDiabetesCouncil, he wanted to know where to find information on meal plans for the Ketogenic Diet. There are many resources online where you can search for meal plans for the Ketogenic Diet. There are also many books you can purchase at your local bookstore. The Atkins Diet is the most well- known Ketogenic Diet in its Induction Phase which is the first 2 weeks in this diet.
One way to find out if the keto diet is not be ideal for your cardiovascular health is by checking if your total-to-HDL cholesterol ratio is above 4 and/or your LDL-P remains high or increases after starting the keto diet. If this is the case for you, then you may fare better with a low to moderate fat diet with plenty of whole foods, fiber, monounsaturated fats, polyunsaturated fats (especially omega 3s), and limited saturated fats.
A related clinical diet for drug-resistant epilepsy is called the medium-chain triglyceride ketogenic diet, in which MCT oil is extensively used because it’s more ketogenic than long-chain triglycerides. (13) Another dietary therapy for epilepsy called Low Glycemic Index Treatment (LGIT) was developed in 2002 as an alternative to the keto diet. LGIT monitors the total amount of carbohydrates consumed daily, and focuses on carbohydrates that have a low glycemic index.) (14)
The ketogenic diet is a low-carb, high-fat diet, similar to a number of popular diets such as the Atkin’s diet. It is primarily known as a weight-loss diet, as it can help boost the metabolism and speed up the burning of calories. While many people think of a high-fat diet as being unhealthy, it is all about the type of fats that you consume. In a ketogenic diet, for example, your protein intake will be quite high, rather than having a carb-heavy diet. Both carbs and fats can be used by the body for energy, but when fat is the primary source of energy metabolism, the body enters a state known as ketosis.
All of our cells need fuel to function. This fuel comes from three sources: fat, carbohydrates and protein, called macronutrients. Too much protein without fat puts us at risk for a handful of complications, so protein can never healthily serve as a primary source of fuel. We are left then with fat and carbohydrates as the main providers of energy – the energy that allow us to do everything from breathing and blinking as we veg out on the couch to swimming the English Channel. Our cells’ preferred fuel comes from carbohydrates, which are easily converted to glucose, which, in turn, is readily converted to energy. This is why athletes “carb load” before they compete. Peak performance occurs when the body has plenty of glucose and glycogen stores available at hand. When glycogen runs out, that’s when the body turns to fat. When there is no more blood sugar for our cells to consume, they seek an alternative form of energy. This energy comes from ketones, which are compounds our body produces from stored fat. So a ketogenic diet is one that is high in fat and very low in carbohydrates, resulting in the production of ketones to be used for fuel instead of glucose.
Obesity has become a serious chronic disease in both developing and developed countries. Furthermore, it is associated with a variety of chronic diseases (1–4). It is estimated that in the United States alone approximately 300,000 people die each year from obesity-related diseases (5,6). Different methods for reducing weight using reduced calorie and fat intake combined with exercise have failed to show sustained long-term effects (7–9). Recent studies from various laboratories (10,11), including our own (12), have shown that a high fat diet rich in polyunsaturated fatty acids (ketogenic diet) is quite effective in reducing body weight and the risk factors for various chronic diseases. The ketogenic diet was originally introduced in 1920 (13). In this diet, the fat to carbohydrate ratio is 5:1. While there was a significant decrease in the weight of obese patients who were on a ketogenic diet (12), the reverse occurred when the diet changed to one high in carbohydrates (14).

The only evidence I could find for the long-term safety of a keto diet is from one 12 month trial. As a result of the study, the researchers found that overweight adults with elevated A1c that followed the keto diet experienced more significant reductions in A1c, lost more weight, and decreased their medications more than those instructed to follow a moderate-carbohydrate, calorie-restricted, low-fat diet.
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!”  

Despite its explosive popularity, there’s a lot of confusion about what the ketogenic (keto) diet really is. “Many people think they’re following a keto diet when they’re really just consuming a low-carbohydrate diet,” says Patti Urbanski, MEd, RD, CDE, a certified diabetes educator with St. Luke’s Hospital in Duluth, Minnesota. “So one person’s ‘keto diet’ may look very different than another’s.”
Try to be patient. Although some people get into ketosis relatively quickly, it can take others a while. Unfortunately, people who are insulin resistant often have a longer journey. Put in a solid month of consistent keto eating, and try to ramp up your physical activity, if possible. Within four weeks, you should definitely be in ketosis and experiencing its benefits.
Note: Because you'll be excluding some major food groups on the keto diet (grains, many fruits) you should definitely think about taking a multivitamin—especially one that contains folic acid, which helps your body make new cells and is often found in enriched breads, cereals, and other grain products, says Julie Upton, R.D., cofounder of nutrition website Appetite for Health.
The side effects of extreme low-carb diets are still a mystery. "The first major drawback is the fact that we really don't have any long-term research about how keto followers fare 10, 20, 30 years down the line," Turoff says. "What will the results look like? Will they regain the weight? Will they suffer health consequences? We also thought smoking and diet pills were a good idea, until long-term studies showed us that we were wrong."

Ketogenesis has existed as long as humans have. If you eat a very low amount of carbohydrates, you starve your brain of glucose, its main fuel source. Your body still needs fuel to function, so it taps into your reserve of ketones, which are compounds the liver creates from fat when blood insulin is low. This process is known as ketosis: It’s like when a hybrid car runs out of gas and reverts to pure electricity.


We are all supposed to be eating 5 servings of fresh fruit and vegetables per day. That provides you with all the essential vitamins and nutrients needed to run a healthy body along with the protein you choose to consume alone with them. I guess if you can fit those into a Ketogenic diet and make that work for you for a lifetime, I would have to say that is absolutely wonderful! I just know, I have a lot of willpower and I only made it 1 year back when I tried. It was just too restrictive. I see too many stories like that. The blogger I wrote about, all the studies, most participants had dropped out at 6 months. No study I have seen has shown anyone who has stayed on it for 10 years, 15, 20, 30, 40 years. If you know one, please let me know!
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.
Recommendations: If you have high levels of LDL particles and VLDL particles, consider adopting a carbohydrate-restricted diet. To optimize your LDL cholesterol levels, consider adopting a diet high in healthy monounsaturated fats and low-carb vegetables. Some examples of keto-friendly foods that are high in monounsaturated fats are olive oil, avocado, and macadamia nuts.
Clinical improvement was observed in Alzheimer’s patients fed a ketogenic diet, and this was marked by improved mitochondrial function. (15) In fact, a European Journal of Clinical Nutrition study pointed to emerging data that suggested the therapeutic use of ketogenic diets for multiple neurological disorders beyond epilepsy and Alzheimer’s, including headaches, neurotrauma, Parkinson’s disease, sleep disorders, brain cancer, autism and multiple sclerosis. (16)
The typical American consumes about 52% of calories from carbs, 33% from fat, and 16% from protein, according to a study published in The American Journal of Clinical Nutrition. This macronutrient breakdown is fairly close to current dietary recommendations from the United States Department of Agriculture, which recommend 55 to 60% complex carbs, 30 percent fat and 15% protein to help prevent cardiovascular disease.
Produced by the liver, cholesterol is also derived from our diet. People often assume eating foods rich in cholesterol will raise cholesterol levels and increase the likelihood of a heart attack. But it’s more complicated than that. Cholesterol-rich foods feature heavily in the keto diet (butter, eggs, red meat); but there are two types of cholesterol. “Bad” LDL cholesterol (think L = lethal) is linked to clogging of the arteries. “Good” HDL cholesterol (think H = healthy) clears cholesterol from the blood.
If you haven’t already jumped on the keto diet bandwagon, I’ll give you a brief introduction. Basically, the ketogenic diet is a super high in fat (65-75% of your diet is fat), a super low carbohydrate (<5% of your diet) and moderate in protein (15-20% of your diet). Surely, not the most balanced of diets considering Health Canada   your diet should contain 10-35% of protein, 45-65% of carbohydrate and 20-35% of fat. So how to you meet that skewed macronutrient distribution? Well, you load up on keto diet staples like meat, fish, butter eggs, cheese, heavy cream, oils, nuts, avocados, seeds and low carb green vegetables. And you cut out all your go-to carb sources like grains, rice, beans, potatoes, sweets, milk, cereals, and fruits. These kinds of restrictive diets tend to make nutrition professionals like dietitians run for the hills but I’m going to give it my honest unbiased account.
The kidneys play an important role in metabolizing protein, and it’s possible that eating too much of the nutrient can have a negative impact on kidney function. While ketogenic diets are supposed to be much higher in fat than they are in protein, many keto eaters make the mistake of loading up on lots of meat, Mancinelli says. The result? You could end up eating way more protein than you actually need.

Practicing intermittent fasting. This works wonders to help patients get into ketosis. Ideally, you’ll go 13.5–15 hours between dinner and breakfast to help your body find energy reserves beyond stored glucose. (Your body can only store reserves for about 24 hours, so if you are eating much less, intermittent fasting will allow you to drop your storage levels way down, requiring your body to burn fat instead.)

Researchers believe that the ketogenic diet can also help patients with schizophrenia to normalize the pathophysiological processes that are causing symptoms like delusions, hallucinations, lack of restraint and unpredictable behavior. One study found that the keto diet lead to elevated concentrations of kynurenic acid (KYNA) in the hippocampus and striatum, which promotes neuroactive activity. Some studies even point to the elimination of gluten as a possible reason for improved symptoms, as researchers observed that patients with schizophrenia tended to eat more carbohydrates immediately before a psychotic episode. (19)
Hi Eric, nice to see you. Some do well on whey instead of protein powders. They do have carbs so be careful. I have learned every little change helps and no beating up allowed. Every improvement helps. It takes 2 weeks to get sugars out of the body. Then cravings will be gone. Good foods also lessen the craving. Apples are great, lol. Good health to you.

Imagine your body is a home with a fireplace in the middle and the heat required to keep it at a comfortable\livable temp is keeping the fireplace burning at a manageable and constant pace. To do this you have two fuel-types at your disposal: Kerosene and Charcoal. (in this analogy Kerosene is carbohydrates and coal is fat). American diets are high in carbs, which is like throwing a bucket full of kerosene on that fire. Will it keep the house warm? Sure, but it burns down fast so you have to keep throwing bucket after bucket on it to keep it going, consuming tons of kerosene, and you get these huge spikes in heat. It is much harder to control the strength of the flame, and thus much harder to keep the house at a constant, comfortable temp.

There’s many suggested interventions for these short-term keto side effects on the internet, but know that there are potential pitfalls of these dietary supplements. While there are benefits for some specific cases, many of us will experience nausea, vomiting, diarrhea, and constipation as a result. Plus, unless they’re prescribed to you by a physician, dietary supplements come with their own safety gamble.


Once the body gets used to manufacturing ketones as the main energy substrate, the body actually has more energy than it previously had, and you won't have to be fighting through all those low-blood-sugar crashes your high-carb meals previously gave you. Additionally, hydration should be an area of high priority, especially before, during, and after exercise.
It has been known for more than a decade that bipolar disorder shares a number of clinical, biochemical and physiologic features with epilepsy and that a similar neurobiology may underpin both disorders. Both conditions cycle, both are risk factors for each other, and anticonvulsant drugs used in epilepsy have been found to be effective in helping manage bipolar illness. 
Diabetes, whether type 1 or 2, are diseases extremely susceptible to the therapeutic level effects of diets that lower insulin. If those diets are also nutrient dense, evolutionarily matched to humans and produce a more generally preferable shift in metabolism, then all the better. This sort of dietary treatment for diabetes holds great promise in their potential for helping out in other diseases like cancer, Parkinson’s and Alzheimer’s disease.

People claiming huge benefits of these supplements – despite the lack of solid scientific support – may sometimes have a financial reason to believe in the supplements. Some of these products are sold under a multi-level marketing arrangement, where sales people are paid based on commission. For example, the company Prüvit sells drinkable ketones, called KETO//OS with a multi-level marketing structure.
A ketogenic diet elevates the levels of ketone bodies in the system—these are the byproducts of the body breaking down fat for energy when carbohydrates are in short supply, a process called ketosis. The average American gets most of their energy from glucose, which comes from carbs and sugars. When you’re in ketosis, though, your body goes into hyper fat-burning mode, also using up stored body fat, which is why it’s effective as a weight-loss strategy.  
Insulin resistance is caused by several mechanisms, one of which is chronically elevated insulin levels. So what increases insulin levels? Mainly sugar. A poor nights sleep can do it too, but sugar is a big one. This can be sugar that is part of our diet or carbohydrates that are broken down to glucose or other simple carbs. Proteins put together with fats can also be converted into sugar, a process called gluconeogenesis. However, it is really the effect of dietary refined sugars and starches (flour) causing blood sugar and insulin spikes (not protein). These insulin spikes from added sugars and flour are then often followed by a blood sugar crash, leading to a sense of discomfort, even sweating, and usually a craving for more high-carb foods.
“Tremendous Results”….guess that’s why the diabetes nationwide gets worse every year, because of the stellar advice your kind is giving out. I’ve been on the virta clinic for two months and already went off insulin, Janumet and Jardiance, which I’ve been on for 10 years, with blood sugars between 80 and 150. The advice you give makes people get sick slower. The ketogenic approach deals with the real issue, carbohydrate intolerance. If you are lactose intolerant you stop ingesting lactose. Type two diabetes is simply carbohydrate intolerance. Stop eating the carbs and the symptoms go away. I think you meet to cite some of the other research out there I’ve read in other books and the work the Virta Clinic has done. In my opinion you’ve cherry picked data to suit your preconceived beliefs.

I think you should give Keto a 3 month trial. You will notice that any inflammation you have will disappear. The best bonus for me is that I now only eat one meal per day. I’m 57 like you. I figure I save 1 hour per day in food prep, eating and shopping. By the time I’m 100 I will have spent 15,000 fewer hours messing with food. That’s like adding 3 years to your life!
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.
Two, exercise, perhaps our most reliable and potent booster of mitochondrial biogenesis in the brain, is downright nootropic. Exercise increases blood flow to the brain, which provides more oxygen and energy but also reduces free radical damage and enhances memory. It stimulates the creation of new neurons and the production of brain-derived neurotrophic factor (BDNF), a chemical that is instrumental in neuron preservation and formation. Exercise also promotes gene expression that supports plasticity, the brain’s crucial power to alter neural pathways.
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 majority of scientists believe the exact opposite. They believe that it was our high fat content in our foods in the caveman days that caused the evolution of man intellectually. The human brain seems to thrive on fat, which might explain Keto’s potential when it comes to neurological impairments like epilepsy, and now studies are being done on patients with autism, and alzheimers. One of the most common side effects people seem to claim to experience is mental clarity and improved focus.


The end result of the “ketone diet” is staying fueled off of circulating high ketones (which are also sometimes called ketone bodies) — which is what’s responsible for altering your metabolism in a way that some people like to say turns you into a “fat-burning machine.” Both in terms of how it feels physically and mentally, along with the impact it has on the body, being in ketosis is very different than a “glycolytic state,” where blood glucose (sugar) serves as the body’s energy source.

Because SO much brain development and growing happens in 0-5, I think that having an abundance of calories, even if they are stored as fat for a while, is a good problem to have.  More often than not, a growth spurt, picking up a new fascination with a sport or activity, and normal development will even out children’s weight as they approach school age.
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.[20][21][22][23][24] 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.)  
And what benefit you will have with “moderate” diets that let you eat bread and others carbohydrates but high insulin ? remember that it is critical to not only look after glucose levels on blood, it is very very important to reduce your intake of insulin to avoid a lot of diseases including metabolic syndrome for high insulin and insulin resistance.
If you’re wondering why iron is at risk on a meat-based diet, hear me out. Many grain foods provide a considerable amount of iron, because wholegrains naturally contain iron in their inner layer called the ‘germ’. Another reason is that some grain products can have iron added to them during manufacturing. So, once you cut grains out, your iron status could suffer, which can lead to unpleasant symptoms like tiredness and lethargy. It can even compromise your immune system.
I have enough carbs in a day for all my needs. Just eating proteins alone raise the insuline level, enough for muscles preservation. And I top it with vegetables. I have more than enough. I just to be clear, I don’t think the human body is dumb enough to burn a lot of muscles when you have 100 pounds of stored fat. Why the body don’t store proteins, if it prefers that? Modern nutrition take our body – and us – for fools!
Polycystic Ovary Syndrome (PCOS) Because women with the infertility condition PCOS are at a greater risk for diabetes and obesity, some clinicians recommend the keto diet, says Taylor Moree, RD, LD, of Balance Fitness and Nutrition in Atlanta. But PCOS is no different from most health conditions mentioned here: Long-term research on the safety is needed.
Has adding more water, salt and fat not helped very much? Are you still feeling achy, tired and off? We recommend you try to endure it for a few more days until the symptoms pass. Research has shown that a very-low-carb diet is best for weight loss and metabolic issues like type 2 diabetes.Keto flu symptoms are only temporary – they’ll be long gone when you are a fat burner.
Seek Nutritional Ketosis, Not Higher Ketone Levels. To gain the most benefit from this diet, you’ll want to aim for a level of ketosis between 1.5-3.0 mol/L on a blood ketone meter. You’ll be there when you are eating well-designed meals that carry you through to the next meal without hunger or other adverse symptoms (ie, nausea, insomnia, crankiness, inability to exercise). Higher ketone levels suggest you have more circulating ketones in your blood but don’t confuse this with efficient fat burning, which is the goal of this diet.
The aim is far broader than suggested by the article here: It’s not just about what you put in your mouth – it’s also about timing and exercise. There are three ways to be in ketosis – which simply means that “fat burning” and not being dependent on sugars. Fasting puts a man into ketosis in 3 days and a woman by 2 days. Endurance exercise gets you there in a couple of hours. Eating a high fat diet will do it too. The goal however is hidden by the detail – it is to acquire a “Flexible Metabolism”. The aim is to switch on the full fat burning capacity and keep it running – which takes from between 4 to 12 weeks physical adaptation (for the muscles to fully be able to use ketones). The heart runs approximately 27% more efficiently on ketones than on glucose! The brain works better too – Alzheimer’s being referred to by researchers as “diabetes 3”. Once you have a Flexible Metabolism you can consume carbs during or after exercise without dropping out of ketosis – though this depends on your own bio-individuality. I can eat quite a lot of carbs – without losing ketosis – my partner cannot.

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.


The understanding of “What is a Keto Diet” has become blurred thanks to the proliferation of Keto Diet “experts”. Many of these “experts” recommend several variants of Keto Diet and lifestyles which they claim can be modified to any walk of life. However, in most instances what they are actually recommending are Low-Carb lifestyle programs. These are neither weight loss programs, nor Ketogenic. With that said, there’s nothing wrong with adopting a Low-Carb lifestyle, but if your goal is weight loss, then changing your eating lifestyle should come after you’ve achieved your weight loss goals.
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.
There are different reasons people might want to achieve ketosis. For certain medical conditions, such as epilepsy, it might be necessary to see the benefits of the diet. For everyday dieters, it might be for the more anecdotal side effects, such as a clearer head. But it can be risky for certain folks, like those with kidney issues, according to experts at the Keck School of Medicine of USC.

The keto diet can be an effective way to reduce excess body fat but there are several cons that should be noted by anyone wanting to follow this eating plan, says Ms. Zarabi says. In fact, the keto diet has serious risks. For one thing, it’s high in saturated fat, which has been linked to heart disease. Additionally, a nutrient deficiency and constipation could occur since the keto diet is very low in fibrous foods such as fruits, vegetables, and whole grains.
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.

To ensure you are getting enough potassium, include avocados and leafy greens like spinach in your daily diet. Sprinkle some unrefined salt on every meal and in your water to replenish your sodium levels as well. Some ketogenic dieters suggest getting at least 5 to 7 grams of salt per day (one teaspoon to a teaspoon and a half per day) during your first week on the ketogenic diet.
Despite its explosive popularity, there’s a lot of confusion about what the ketogenic (keto) diet really is. “Many people think they’re following a keto diet when they’re really just consuming a low-carbohydrate diet,” says Patti Urbanski, MEd, RD, CDE, a certified diabetes educator with St. Luke’s Hospital in Duluth, Minnesota. “So one person’s ‘keto diet’ may look very different than another’s.”

In a survey of both children and adults, researchers found that a very low carbohydrate diet promotes “exceptional glycemic control” in those with type 1 diabetes mellitus. When it comes to type 2 diabetes, the Journal of American Medical Association recently published a review examining the effective use of the ketogenic diet in those with type 2 diabetes.


Financial disclosures: There were no conflicts of interest reported except for Dr Bernstein who has received royalties for books on the management of diabetes (which were used by members of the online social media group surveyed in this study). Dr. Hallberg who holds stock options and receives research support from Virta Health, and consulting fees from Atkins. Dr. Rhodes is the site principal investigator in clinical trials for pediatric type 2 diabetes that are sponsored by Merck and AstraZeneca. Dr. Westman has an ownership interest in companies using low-carbohydrate principles, and he receives royalties for books related to low-carbohydrate diets. Dr. Ludwig has received royalties from books on nutrition and obesity; and Dr. Galati is author of Eating Yourself Sick: How to stop obesity, fatty liver, and diabetes from killing you and your family (2018).
Keto-adaption is a state, achieved through significant reduction of carbohydrate intake (typically to less than 50 grams per day), where the body changes from relying on glycogen as its main source of energy to relying on fat.  Specifically, the brain shifts from being primarily dependent on glucose, to being primarily dependent on beta-hydroxybutyrate.  This has nothing to do with what a diabetic patient is experiencing in DKA, but does illustrate how poorly informed and quick to react the medical community is.   DKA and nutritional ketosis (or keto-adaptation) have as much in common as a house fire and a fireplace.
However, we need to consider that most of these studies failed to equate for both calories and protein, and it is likely that if similar weight loss was achieved, these health outcomes would look similar regardless of the diet used. This is supported by the Johnston study from Arizona state which saw similar outcomes when calories and protein were equated.
Controls glucose and reduces diabetic symptoms. In a randomized study of overweight adults with type 2 diabetes, the participants were divided into two groups. The first group followed a 32-week ketogenic diet program while the second group followed the conventional low-fat, diabetes diet plan. At the end of the study, the ketogenic diet group improved their glycemic control and lost more weight than the other group. The research showed that the ketogenic diet improved the participants’ blood glucose levels while also reducing the need for insulin.

Jalali says people following the diet have the best chance of keeping the weight off if they stay on it long term. And that’s not always easy to accomplish. The weight may come back if you go back to your regular eating habits. And regaining weight may lead to other negative effects. “Chronic yo-yo dieting appears to increase abdominal fat accumulation and diabetes risk,” notes Clark.
Experts are split on whether the keto diet is a good idea. On the one hand, Lori Chang, registered dietitian and a supervisor at the Center for Healthy Living at Kaiser Permanente West Los Angeles, says using a “cleaner” source of energy—ketones rather than quick-burning carbohydrates—can improve mood and energy levels. When you eat refined carbohydrates or just too many carbs in general, the blood is flooded with excess insulin, Chang says. "This can lead to a blood sugar rollercoaster that stresses the body and negatively impacts energy levels and mood. When you’re in a state of ketosis, however, ketone bodies don’t require insulin to cross the blood-brain barrier, which wards off unfavorable blood sugar levels."
The problem comes when people remain ketotic for extended periods. We know with confidence that long-term ketosis poses substantial risk for health complications because thousands of children have followed ketogenic diets over the years as a means of suppressing intractable grand mal seizures unresponsive to drugs, seizures that can lead to irreversible brain damage if not stopped. A ketogenic diet reduces seizures by approximately 55%. Because seizures are a chronic problem, these kids maintain ketosis for months to years.
I have patients that have lost tons of weight on keto. They do go off some meds. I also have people who eat a moderate amount of good carbohydrates, and they have lost tons of weight, and been taken off meds, had improved markers, even reversal. I think both approaches work, as I have seen in practice. Many people cannot stay on a keto diet forever. I for one, prefer to have some carbohydrates. I try to pick the right ones. If this works for you, then just be sure to have some medical supervision, which it sounds as though you are doing.
I’ve lost 30 pounds in 2 months, I feel better than I ever have, energy levels are up, my skin issues have cleared up, and I am training to run a 5k with my 14 year old. This is the only diet I’ve tried that has been easy to stick to. For me I could never do a diet if I didn’t like the food. Not a chance I could go vegan. Anyone reading this I strongly suggest you do your own research. No offense to the writer but nobody should only look to one opinion as the be all and end all on any topic. Mark Sisson is an amazing resource, has been eating keto for a long time and *gasp* is a marathon runner. On Netflix check out The Magic Pill for some eye opening stuff. Just do as much research as you can before either jumping in or dismissing it. There are some amazing and delicious foods that are keto-friendly, you just gotta put in the time to find them. Keto is not just a diet, it’s a lifestyle that includes proper exercise (to avoid loss of muscle mass among many other health benefits), stress management and proper sleep. Be informed.
Second, the ketogenic diet suppresses insulin like growth factor (IGF-1). This molecule is associated with the formation and progression of cancerous cells. IGF-1 levels are increased when we eat more carbohydrates. Because the ketogenic diet is much lower in carbohydrates, scientists suspect that this suppresses IGF-1 production, slowing the formation of cancerous cells.
I was diagnosed in 2004 with Brittle Type 1 diabetes, peripheral and autonomic neuropathy, and Hypothyroidism. A short time later with Gastroparesis due to the nerve damage from diabetes. Since then, I had followed every guideline and rule that the Endocrinologist and Primary Care Doctors had told me to follow. NOTHING WAS GETTING BETTER. In fact, I was gradually getting worse. So many ups and downs. Extreme highs (250-500 bgl ) to seizures from crashes (drop from 300 to 13 in no time). It was a constant battle with adjustments in insulin intake (and different insulins NPH, R, Novolog, Humalog, Lantus), carb intake, exercise and one contributing factor was the Gastroparesis. Meds were taken for the Gastroparesis but I always had side effects from meds. To my point. I was kicking a dead horse and I told them this. My sister and mom had come across the ketogenic way of eating and it dramatically improved thier lives. Mom was diagnosed way back with Type 2 and within a week or two she was off of her meds completely. I was totally interested. So, I decided to go for it on April 17, 2017. I did go through some rough patches of what they call Keto Flu. It did pass after a couple weeks. I was gaining so much energy like never before as well as mental focus. The even greater aspect of this all was, I had DRAMATICALLY LOWERED MY INSULIN INTAKE TO ALMOST NONE! My Lantus was always being adjusted from 30-40 units daily (and changed from AM to PM to splitting it to half AM, other half PM). I was on a sliding scale of Humalog or Novolog. From 4-6 units per meal and then there were the corrections throughout my day (some daily totals could be up to 40 UNITS)! Very exciting for me to only take 2 units of Lantus in the AM and daily totals of Humalog/Novolog….1.5-3 units! Other great things I began to notice, neuropathy pains were fading and finally GONE. No more nights up stinging, burning and RLS (restless leg syndrome). So, in my life, there are no questions or hardships on whether I can get off of this way of eating. It’s either do or die. If someone truly wants to have a better life, they can. The sad thing is, doctors and nutritionists aren’t being educated in the real facts. My primary care doctor isn’t willing to help me with all the labs I need nor listen. Always telling me “You need carbohydrates and insulin to live.” All that know me see the dramatic change for the better. I’m doing the Ketogenic way of eating with intermittent fasting for the rest of my life. The alternative IS NOT WORTH a lifetime of illnesses and suffering.
Oh how I miss you, delicious high-fat smoothie 😫 🌿🌱🍃Day 15 on carnivore and I am feeling quite amazing though! 🥩 ~ UPDATE: I don’t have “recipes” I make food to taste but if I recall this was something like: -a handful of blueberries -half a carton of coconut milk -macadamia nuts -a couple glugs of @perfectketones MCT oil -some chunks of cacao butter -some chunks of coconut butter -half avocado -spinach, kale, cabbage -some ice and maybe a little water to get consistency right MUST use a badass blender (I use blendtec) -toppings: you can see them. Put what you like to eat on top.
We are brazilian, living in Brazil. My daughter, Isabel, 21y. o., born in 1996, has syndrome of deficiency of Glut1. She was diagnosed around her first year of life. At that time her baby bottle, her begining diet meal, was 50ml water plus 50ml oil plus vitamin. Since then, which means, for 20 years, she is under this diet. For almost 18 years under 4:1 proportion. At this right moment 3:1. The only problem she had since started the diet were kidney stones in 2002. Nothing else. Grateful to the diet she doesn’t take any kind of medicine to avoid seizures. Her health is perfect, no colesterol at all. We are at your will for any issues related to her health.
The ketogenic diet is a high-fat, adequate-protein, low-carbohydrate diet that in medicine is used primarily to treat difficult-to-control (refractory) epilepsy in children. The diet forces the body to burn fats rather than carbohydrates. Normally, the carbohydrates contained in food are converted into glucose, which is then transported around the body and is particularly important in fueling brain function. However, if little carbohydrate remains in the diet, the liver converts fat into fatty acids and ketone bodies. The ketone bodies pass into the brain and replace glucose as an energy source. An elevated level of ketone bodies in the blood, a state known as ketosis, leads to a reduction in the frequency of epileptic seizures.[1] Around half of children and young people with epilepsy who have tried some form of this diet saw the number of seizures drop by at least half, and the effect persists even after discontinuing the diet.[2] Some evidence indicates that adults with epilepsy may benefit from the diet, and that a less strict regimen, such as a modified Atkins diet, is similarly effective.[1] Potential side effects may include constipation, high cholesterol, growth slowing, acidosis, and kidney stones.[3]
I’m in ketogenesis now – 3 weeks in. Lost over 10kg. Protein shakes. Great. But what I wanted to add was that i’m Diabetic (2) and quite badly so. I was Injecting insulin twice a day – Novomix (part immediate, part slow acting). But since I went into keto, my blood sugar has been steady between 5-9, normal range. No injections needed. And no hypo attacks either – that occurs below a reading of 4, for me. This is NOT a cure of course – it’s directly related to low carb intake. But I do wonder if discontinuing insulin is partly responsible for my improvement in alertness, activity level and so on. Magnesium tabs, 1000 units twice a day, have also been helpful – I suffer leg and foot cramps due to spinal arthritis – but they had worsened until I upped the dose.

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.

If someone tries to tell you that the Keto diet is dangerous because of high protein consumption you can pretty much stop them right there.  The calling card of the keto diet is “Low carb, moderate protein, high fat” and the recommended protein dosage usually falls between 60-120g/protein per day depending on your weight and lean body mass.  This is not a high protein diet.  Anyone eating significantly more protein than they require is probably kicking themselves out of ketosis and is therefore not following a keto diet.
There are different reasons people might want to achieve ketosis. For certain medical conditions, such as epilepsy, it might be necessary to see the benefits of the diet. For everyday dieters, it might be for the more anecdotal side effects, such as a clearer head. But it can be risky for certain folks, like those with kidney issues, according to experts at the Keck School of Medicine of USC.
In part, keto diet weight loss is a real thing because high-fat, low-carb diets can both help diminish hunger and boost weight loss through their hormonal effects. As described above, when we eat very little foods that supply us with carbohydrates, we release less insulin. With lower insulin levels, the body doesn’t store extra energy in the form of fat for later use, and instead is able to reach into existing fat stores for energy.

But when you consume a high-carbohydrate diet, your brain often can't convert enough glutamate into GABA because it's using glutamate as an energy source. This imbalance can lead to neurotoxicity, and this impaired functioning could potentially lead to brain fog. For reasons not completely understood, ketosis seems to favor an increased production of GABA, which can lead to reductions in neurotoxicity and, therefore, brain fog.

Note that although the front label on a potassium supplement may list 595 mg as the dosage, each tablet only contains 99 mg of pure potassium, which can be verified on the detailed “Supplement Facts” label on the back of the container. Taking up to 1000 mg of supplemental potassium per day should be safe for most people who aren’t able to meet their needs through food alone.

Researchers are divided over whether the keto diet is good for people who don’t need to follow it for medical reasons. Since it doesn’t differentiate between saturated and unsaturated fats, dieters are at risk of raising their cholesterol levels. And because the heavily restrictive diet cuts out most fruits and vegetables, it can also lead to nutrient deficiency. The Harvard Health Letter warned that with so much fat and protein to metabolize, keto practitioners may experience liver and kidney problems as well.  
There are seemingly endless options to curate a diet to meet every notion or need. However, those living with diabetes may find that these diets don’t always work to balance glycemic control and blood sugar. So what about the ketogenic diet? Is it a fad that will one day be supplanted by the next newest way to eat, or will the science behind it ensure it keeps a lifelong and loyal following? And if the latter, what role can it play in the lives of those living with diabetes?

“Despite its temporary side effects, we have always suspected that the ketogenic diet is relatively safe long term, and we now have proof,” says senior investigator Eric Kossoff, M.D., a pediatric neurologist and director of the ketogenic diet program at Hopkins Children’s. “Our study should help put to rest some of the nagging doubts about the long-term safety of the ketogenic diet,” he adds. 
By going on a ketogenic diet, you are far more likely to increase your level of fiber intake, primarily through fruits and non-starchy vegetables. This increase in dietary fiber will help aid digestive health by promoting peristaltic motion and easing the passage of bowel movements. This can lower your risk of indigestion, constipation, diarrhea, bloating, cramping, gastric ulcers and even colorectal cancer.
Eating slightly more carbs may potentially slow down weight loss and mute rapid, dramatic health improvements, but it can still lead to better health, especially if you are cutting out sugar and processed foods. And keto flu will no longer be an issue. Once you’ve adapted to low-carb eating, feel free to try eating less than 20 grams of carbs again to see whether your body prefers this or slightly higher carb intake.
Healthy fats are crucial on a ketogenic diet, but people who have been following the official dietary advice don’t know what healthy fats are. In short: all natural fats that you find in fish, meat, nuts, olives, coconut, and full-fat raw dairy products are healthy for diabetics. On the other hand, oxidized seed oils and the trans fats in margarine should be avoided. Learn more about good fats vs bad fats here.
The ketogenic (or keto) diet was initially designed to treat severe epilepsy in infants and children. As an intervention diet, it was intended to be administered for short periods of time under the supervision of a medical team. Now popular for it’s rapid weight-loss side effects, the diet has moved to the mainstream public as an alternative low-carb diet.
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.

The key of these miraculous healing effects relies on the fact that fat metabolism and its generation of ketone bodies (beta-hydroxybutyrate and acetoacetate) by the liver can only occur within the mitochondrion, leaving chemicals within the cell but outside the mitochondria readily available to stimulate powerful anti-inflammatory antioxidants. The status of our mitochondria is the ultimate key for optimal health and while it is true that some of us might need extra support in the form of nutritional supplementation to heal these much needed energy factories, the diet still remains the ultimate key for a proper balance.”
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.
If you are pregnant or are nursing, you should not follow a Ketogenic diet. You will not receive enough of the recommended carbohydrates, vitamins and nutrients necessary for yourself and your growing baby on this diet. Your obstetrician will recommend how many carbohydrates you should consume per meal and for snacks during each phase of your pregnancy. They will likely refer you to a Certified Diabetes Educator for nutritional counseling as well. Please check out The Diabetes Council’s FAQ’ About Gestational Diabetes for all your gestational diabetes related questions.
Louella you are absolutely wrong. It’s actually funny to me that this dietitian talks about the keto diet to such an extent but neither you nor her ever mention Gluconeogenesis. Yes your brain has specific areas that can only use glucose, but the human body is a wonderful thing and can use a few different substrates to synthesize glucose without you ever having to eat it yourself. Look up Gluconeogenesis. Your body has the ability to convert the amino acids you find in protein into usable glucose for your brain. The fact that you don’t know this shows me how uneducated you are about the ketogenic diet in general. Perhaps you should read up on the subject before you start trying to sound like a scientist who clearly has no idea what she is talking about. Thanks.
While a ketogenic diet helps normalize blood sugar (glucose) levels and can help you maintain or reach a healthy weight, an alkaline diet is beneficial for its anti-aging effects— especially lowering inflammation, boosting detoxification, and promoting hormonal balance, immunity and more. Traditional ketogenic diets usually miss the important factor of restoring alkalinity. For many patients the key is to reach an alkaline pH first before beginning keto in order to prevent feeling agitated, anxious, uncomfortable or overly hungry.
To be on the safe side, be sure to discuss with your doctor whether the keto diet is right for you before you drastically change your eating habits. While the diet has roots in medicine, its widespread use is still new, and not every doctor understands the keto diet. For more information, you can look to national programs that are gaining steam. Two examples: Virta Health, where they are studying the diet’s role in prediabetes and type 2 diabetes treatment, and the Cleveland Clinic’s Functional Ketogenics Program.
Once the body gets used to manufacturing ketones as the main energy substrate, the body actually has more energy than it previously had, and you won't have to be fighting through all those low-blood-sugar crashes your high-carb meals previously gave you. Additionally, hydration should be an area of high priority, especially before, during, and after exercise.
