The keto diet involves a very high consumption of dietary fats, and very low carbohydrate consumption. Through these nutritional changes, the body reduces its use of glucose for fuel, and increasingly uses ketones (derived from fats). The diet was first used to control epileptic seizures, but there is growing body of research showing positive effects on Alzheimer’s disease, Parkinson’s disease, traumatic brain injury, inflammation1, and diabetes.
If you’re on a very high fat, very low carb diet – like a traditional Inuit diet – your brain will eventually be able to use fat-derived ketones for about 50-75% of its energy requirements. Most ketones are produced in the liver, but astrocytes in the brain also generate ketones themselves for use by neurons. You think we’d have that kind of set up in our brains if ketones weren’t useful to have around? If all we could do was burn glucose up there, what would be the point of even having localized ketone factories? 
I’m discouraged to see that nowhere in the article nor in the comments is there a mention of a diet’s best fit to genetics. Consider if someone is an APOE E2 carrier and/or has certain polymorphisms of the APO5 gene. These are quite rare in Okinawa but much more prevalent in the USA (12% of the population). According to a number of well-designed studies, these genetic characteristics point to a higher fat, lower carbohydrate diet as beneficial and even a “moderate” carb diet as problematic.
If the liver is resistant to insulin, that's a bad sign for the rest of the body and could mean there's an increased risk of developing type 2 diabetes, the researchers said. What's more, these results are concerning because overweight patients seeking to reduce their risk of type 2 diabetes by following a ketogenic diet could unintentionally be increasing their risk for developing the disease, at least in the first few days of their diet. 
The following measurements were made every other week: anthropometric and vital sign measurements; urine testing for ketones; and assessment for hypoglycemic episodes and other symptomatic side effects. Weight was measured on a standardized digital scale while the participant was wearing light clothes and shoes were removed. Skinfold thickness was measured at 4 sites – the average of 2 measurements at each site was entered into an equation to calculate percent body fat [12]. Waist circumference was measured at the midpoint between the inferior rib and the iliac crest using an inelastic tape; 2 measurements were averaged in the analysis. Blood pressure and heart rate were measured after the participant had been seated quietly without talking for 3 minutes. Certified laboratory technicians assessed urine ketones from a fresh specimen using the following semi-quantitative scale: none, trace (up to 0.9 mmol/L [5 mg/dL]), small (0.9–6.9 mmol/L [5–40 mg/dL]), moderate (6.9–13.8 mmol/L [40–80 mg/dL]), large80 (13.8–27.5 mmol/L [80–160 mg/dL]), large160 (>27.5 mmol/L [160 mg/dL]). Hypoglycemic episodes and symptomatic side effects were assessed by direct questioning of the participant and by self-administered questionnaires.
Carbohydrate facts: Simple = bad, complex = good? Carbohydrates provide energy for the body, but the health benefits they offer depend on the type of carbs we consume. Complex carbs, found in brown rice, for example, contain more nutrients than simple carbs, such as white rice. Refined carbs, such as sugary drinks, are best avoided, as their nutritional value is low. Read now
“If not done right, this diet can cause havoc on our bodies,” says Mancella. “As a society, we’ve turned to a culture of restriction and extremes in order to obtain unrealistic beauty and aesthetic standards without considering the long-term consequences. This diet doesn’t only affect metabolism, but also every other component of our bodies. By introducing potential vitamin and mineral deficiencies, we’re possibly trading the present moment for quality ones in the future.”
In the first few days of the keto diet, it’s not uncommon for people to experience the “keto flu,” a brief period in which you may have headaches, fatigue, confusion, and nausea. These symptoms are a sign that your body is making the switch from burning glucose (sugar from carbs) for energy to burning fat—a process called ketosis. The changeover can leave you feeling depleted for a day or two, but once you break through to the fat-burning phase, you may find you have much more energy and greater endurance. “You are able to do more without hitting ‘the wall,’ says Carrie Burrows, PhD, a health and fitness expert. “When we use fat as fuel, our endurance improves and is more sustainable.” That extra energy will carry over to your workouts, Dr. Burrows says. Here are more things you need to know before starting the keto diet.
According to Dr. Cabeca, “Fasting is a key aspect of a healthy diet and has many anti-aging effects.” In particular Dr. Cabeca recommends fasting to women during or after menopause due to it’s anti-aging effects. For example, a 2016 study published in the Journal of the American Medical Association found that when women went 12.5 hours between dinner and breakfast (a common form of fasting), the overnight fast seemed to help improve immune system functioning to the point that it reduced their risk for breast cancer.

In a March 2018 blog post, Dr. Ede provides a range of very helpful tips for anyone already on mood-altering or psychiatric medications who want to try a ketogenic diet, such as how to talk with your psychiatrist or mental-health provider and what laboratory metabolic tests the doctor should order to help monitor your response to the diet. Most importantly, she provides details about some specific medications — notably specific antipsychotic medications, anticonvulsant medications, and lithium — that should be carefully monitored.
But more than that, people just don’t like giving up carbs. Dr. Kevin Fontaine, a Professor of Health Behavior at the University of Alabama at Birmingham School of Public Health and an expert on the ketogenic diet points to this as one of the main drawbacks of the diet. “Many people find it very difficult to give up carbs, and may be unwilling to do it. Plus, if you’re on the diet and eat a few carbs, you feel physically terrible. It’s hard to stick with this diet, especially while traveling.”

The problem is: it flies in the face of the way we have been taught. Our society (as an American), and our medical community, have preached for years that FAT is bad, and you should limit it. However, recent FACTS beg to differ. So many people rail against the keto diet because they just feel that it can’t be good…after all, you eat so much fat on it, it can’t be good for you! Facts are facts…they don’t care about your feelings. Fat is not the enemy. Sugar is.
"The diet was introduced in the 1920s as a way to treat epilepsy and then sort of fell out of popularity with the introduction of anti-seizure drugs," Turoff says. What's more, ketosis (the goal of keto, a state where the body uses fat for energy instead of carbs) is something seen in people during periods of starvation—including in people with anorexia nervosa. "The body is deprived of carbohydrates and thus has to turn to ketone bodies as a fuel source," Turoff explains. "People really need to understand that it's not just a low-carbohydrate, high-fat diet—it actually changes the way your body uses fuel."

If a person does not like his or her body, he or she will not be able to have the same amount of confidence as someone who loves their body. It is very important to be confident for a person to do well in his life. Without confidence, no one really takes you seriously and you are unable to impress anyone or show your talents to the world. To make this happen, this formula increases confidence in the user so that they can be more inspired from their own bodies rather than others.


“Keto diets should only be used under clinical supervision and only for brief periods,” Francine Blinten, R.D., a certified clinical nutritionist and public health consultant in Old Greenwich, Connecticut, told Healthline. “They have worked successfully on some cancer patients in conjunction with chemotherapy to shrink tumors and to reduce seizures among people suffering from epilepsy.”
Beyond the short-term effects of the keto flu, the diet can also negatively impact your digestion and gut in the long run. One 10-year study conducted on using keto to manage pediatric epilepsy found the following GI side effects over time: constipation, high triglyceride levels, high cholesterol, diarrhea, lethargy, iron deficiency, vomiting, and kidney stones.
"On a ketogenic diet, your intake of fruits and vegetables is extremely limited, and we all know how important the fiber, vitamins, minerals, and other compounds in fruits and veggies are," says Libby Parker, R.D., a dietitian who specializes in treatment and prevention of eating disorders. It's true: There are a lot of healthy but high-carb foods you can't eat on the ketogenic diet. That's one of the reasons keto is usually pretty low in fiber, which isn't so great long-term. "Fiber is not only protective against many gastrointestinal cancers, it is also a big factor in fullness and weight loss," Parker explains. "Furthermore, constipation is very common on low-fiber diets like the keto diet." (That said, These Healthy, High-Fat Foods Can Help You Feel Full Longer.)
“When you start the keto diet, you lose sodium and other electrolytes in the urine due to reductions in insulin,” says Yawitz. “This is a major contributor to symptoms of keto flu.” So it’s important to replenish sodium through the diet, especially if you exercise or sweat a lot. “This can help ward off more serious side effects that are seen with long-term sodium deficiencies,” says Yawitz. These include lethargy and confusion — and in extreme cases, seizures, coma, and death, according to the Mayo Clinic.
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.
Constipation is a common side effect of low-carb eating plans, including the ketogenic diet. Severely curbing your carb intake means saying goodbye to high-fiber foods like whole grains, beans, and a large proportion of fruits and vegetables, says Ginger Hultin, MS, RDN, Seattle-based nutritionist and spokesperson for the Academy of Nutrition and Dietetics.
This process of burning fat provides more benefits than simply helping us to shed extra weight — it also helps control the release of hormones like insulin, which plays a role in development of diabetes and other health problems. When we eat carbohydrates, insulin is released as a reaction to elevated blood glucose (an increase in sugar circulating in our blood) and insulin levels rise. Insulin is a “storage hormone” that signals cells to store as much available energy as possible, initially as glycogen (aka stored carbohydrates in our muscles) and then as body fat.

The researchers hypothesized that the positive effects that the ketogenic diet has on migraines are due to how ketone bodies inhibit neural inflammation and enhance brain mitochondrial metabolism. The ketone bodies do this by blocking high concentrations of glutamate (commonly found in both migraine and epilepsy sufferers) and reducing oxidative stress.


Why not just rest on the opinion that it is not a fad diet and has been around for a long time as a diet that works for some people. Some of our youth on reddit may be doing it because they have diabetes (like my Son) Many of these kids are getting this from the poor American diet and low activity because of computers and phones. So if they can take a break from that and try to take an active and creative interest in this diet (which is a good diet for some) then why not just be respectful of that. My Sons doctor put him on this diet, we are doing it as a family and loving it! His blood sugar is normal after 1 1/2 months and we have all lost weight. BTW most if not all the foods you tried I would def eat! ???? There is def some concern about doing this way of eating carefully and making sure we are in balance with our nutrients. We have cheat meals once a week, so not feeling deprived at all!
Inadequate calories: Keto’s satiating qualities are a double-edged blade. They help us eat less and lose body fat without really even trying, but they can also sometimes lead us to eat too little. This can cause a reaction in your body to slow down metabolic function and make you feel generally less energetic at rest. One solution is to cycle periods of generally increased caloric intake, and increased intake of nutritious carbs by default. This suggestion is totally different from the suggestion to engage in purposeful carb refeeds, where you binge on nutrient-devoid carbs in the name of a cheat day. This is never advised for any reason.
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.
Keto Ultra Diet burns fat in the user’s body. It does so by two different ways. As mentioned above, the supplement plays a role in the mobilization of fats in the body. Consequently, the fats are burnt for energy. As long as these fats are kept in their stored form, they are not used up. Keto Ultra Diet removes excess fat from the body so that the user can be slim.
Case in point, Steve Richert has Type 1 Diabetes and his September 1, 2015 blog The Ketogenic Diet and Type 1 Diabetes: What I Eat. He gave it the good old college try and has fearlessly came back and showed us all his results. His cholesterol increased, which just like mine, was due genetic factors, but was exacerbated by the Ketogenic Diet. So, what’s the best part of Steve’s story? He’s coming close to being right in line with what I would recommend for him! Moderation and the mediterranean diet; he’s currently trying a modified ketogenic diet or really a modified mediterranean diet. Brilliant and exactly what we all should be doing!

Hello Dr. Jockers, in the past few months I have been working on cleaning up my diet. Eating gluten & dairy free as much as possible. I started taking exogenous ketones at the same time. I got a juicer for Christmas and about 3 weeks ago I added celery juice ( 1st thing in the AM) and a carrot, apple, turmeric juice in the afternoon. Some days I am fine and other days I have sudden diarrhea within an hour of drinking the celery juice. I’ve read so much about the benefits of drinking it but am wondering if the ketones are reacting to it adversely? Please let me know your thoughts on this.

My son started the Keto Diet (not perfectly) with the ok of his Dr and a Different Oral Chemo at the same time. Last Tuesday an MRI indicated no new growth or no new tumors. We don’t know if the new Chemo, Keto diet, lots of prays or what has stopped the tumors from growing.I found your site after looking for possible adverse reactions to Keto Diets, and appreciate your research. His platelets are low now and never have been low before. This is stopping the next Chemo treatment. I understand that being on Chemo for 12 months could have created the low platelets and now the possibility that the Keto Diet could also be causing low platelets is frustrating. They will do a new blood test Tuesday to see if the platelets have increased. Any suggestions about how if possible to increase the platelets on the Keto Diet would be helpful.

To put it roughly, various supporters of the ketogenic diet affirm that it is highly effective in fighting cancer. Although the studies in this area are extensive, one has to note that they have been limited to animals alone. The studies developed on human subjects, however, highlighted that following the ketogenic diet prevents diseases such as gastric, colon and prostate cancer from progressing. Although this diet cannot cure cancer, it could prevent it from further advancing, while having other notable health advantages.
The same is true for meat. You’ve probably been told to avoid red meat when in fact you should not. Meat is an integral part of any diet including the ketogenic diet. There is no reason to avoid it (OK you’re excused if you’ve been bitten by a lone star tick!). The ketogenic diet reduces cardiovascular risk factors and improves the lipid profile by increasing HDL and lowering triglycerides [9,10].
Ultimately, we understand that there’s no magical diet and that some prefer to eat more fat while dieting. We have dealt with over 15k clients, many of which have medical restrictions and require different parameters while in a caloric restricted state. No matter what your limitations, preferences or needs are while on a diet plan. We can build you a Macro Blueprint that will help you lose unwanted fat.

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.

Adequate food records were available for analysis in a proportion of participants at each of the 4 timepoints (Table ​(Table2).2). Participants completed food records at a mean of 2.5 and a median of 3 timepoints. In general, comparing baseline to subsequent timepoints, mean carbohydrate intake decreased substantially and energy intake decreased moderately while protein and fat intake remained fairly constant.
Hydroxycitric acid is the most important ingredients used in ultra diet shark tank pills. This acid will help you to control your appetite. The main reason behind belly fats is that people feel more hungry and take a lot of food, but when you consider this diet, it will help you more and let you fill less hungry, cause Keto ultra is in rich of hydroxy citric acid. It will help in the digestive system and is more responsive for controlling appetite and hunger.
The whole area of calcium supplementation is rife with misinformation. Mainstream docs assume that osteoporosis is due solely to lack of calcium, ignoring that you need to have adequate Vit D levels to absorb the calcium in the first place (and their idea of adequate D blood levels are absurdly low) as well as Vit K2. Since bone is made of calcium phosphate, you also need adequate phosphate as well. Milk contains calcium phosphate – no surprise since it is designed to build the bones of the growing animal – so dairy is your best source of calcium. You also need protein since bone is calcium phosphate within a protein matrix. To rebuild osteoporotic bone you need 1.2gm/Kg of body weight, 50% more than the RDA of 0.8gm/Kg.
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.”
Reduce daily net carb intake to less than 20 grams: Although it’s possible that you may not need to be this strict, eating fewer than 20 grams of net carbs every day virtually guarantees that you’ll achieve nutritional ketosis. What does 20 grams of carb look like? Use our visual guide to find out, or simply try our keto recipes and meal plans that limit carbs to less than 20 grams per day.
A great long-term benefit of the ketogenic diet is reduced cravings for sugar and other unhealthy foods. However, you might initially have stronger cravings for carbs during the transition period. This can last anywhere from one to two days to around three weeks. But stick it out! At the end, you’ll be pleased with the reduced, and often eliminated, cravings.
I can buy clothes off the rack. Better than being obese. My brain is sharper. I get more stuff done. I don’t sit around. I feel like I can feel the fat melting off. I have trouble sometimes eating enough. After 40 years if being very obese on and off, I think I am better off. I hope to use it when I need it after I reach my goal. The blood tests will prove it.
Click here to join my newsletter and I’ll keep you posted when I get new articles up (FYI: as a heads up, I also write about entrepreneurship and web development. I started writing about fat metabolism and ketogenic dieting here at KetoSchool out of pure hobby interest, as there are relatively few resources out there that teach the underlying science).
Many people and even some doctors confuse nutritional ketosis with (diabetic) ketoacidosis. Ketoacidosis occurs in uncontrolled diabetes when the pancreas cannot secrete enough insulin to exert its action in cells, so blood glucose levels and blood ketones both skyrocket to dangerously high levels. Ketoacidosis has nothing to do with nutritional ketosis which is when ketones are produced from all the dietary fat you’re relying on and can thus keep your blood sugar levels under control at low and stable levels.

After seeing thousands of patients now for years and from personal experience, I still believe it comes down to staying away from processed foods and cooking at home whenever possible. Eating a variety of fresh fruits, vegetables, proteins, and fiber. Also, cutting out any sugary liquid calories; staying away from sodas, juices and the infamous sweet tea! Keeping stress levels under control and incorporating exercise into your routine will also be key to breaking through challenging times when you are having trouble with continued weight loss.


The crazy thing is it is not hard, if it matters. Sure I can see it being hard for someone who does it to lose weight, then when they get closer to their ideal, they want to have treats, etc. Well, for a type one diabetic there’s no end in sight, this is it, and it’s a relatively complication free life (many people reverse their complications when they bring their A1C down to normal) vs. one with inevitable complications. So, perhaps it was too hard for you after a year (you didn’t say, but I assume you are not a type one diabetic), but that is a choice you can make. Not I.
This diet also entails weight loss because it gets rid of excess water content in the body due to a lower amount of insulin produced. The food is broken down into simple sugars, with excess energy stored as complex sugars. The pancreas produces insulin that helps regulates sugar breakdown in the body. The body needs less sugar in switching to higher intake of fat. The liver can break down fatty acids to energy in ketogenic diets. Due to eating less carbohydrate or sugars, the production lowered. In a study, 90% of all type 2 diabetics were able to lower or completely eliminate their diabetic medication after 6 months of being on a low carbohydrate diet.
"Electrolyte imbalances can also be common if keto followers aren't aware of hydration needs," Turoff says. It's important to stay hydrated on keto, she says, especially in the beginning. "As you limit carbohydrates, your body produces less insulin, and glycogen stores (how carbs are stored) in the muscles and liver are depleted. For every 1 gram of glycogen that's depleted, you lose about 3 grams of water." This causes the kidneys to flush out more water, and along with it, electrolytes your body needs like magnesium, calcium, sodium, and potassium. "Imbalanced electrolytes can lead to muscle cramps, irregular heartbeat, fatigue, cognitive distortions, and lack of body temperature control," Turoff says. Some people may also be more likely to get kidney stones while on keto due to inadequate hydration, according to Turoff. (PS: These Are the Hydration Tips Every Fit Girl Needs.)

“What many diabetics aren’t aware of, is that it is the fat that is the problem when it comes to type 2 diabetes. Nearly 100 years ago, healthy volunteers were split into two groups – half were fed a fat-rich diet, and the other half on a carb-rich diet. Within just two days, the fatty diet groups’ glucose intolerance skyrocketed to amounts twice as high as those fed a carbohydrate-rich diet (9).
Yes you can lose fat on a low carb because it’s just another low calorie diet. How do I know this? I’ve done low carb, (Atkins, etc) high carb, (Slimming Word) moderate carb etc and log my food and was shocked each time to see they were all low calorie. After the initial week or so the rate of fat loss is same as any other diet. It’s calories in calories out. Simple. It’s what some call indirect deficit diet placing silly restriction, rules can eat must eat etc. and of course you lose weight but nothing to do with low carb. It works because it’s a low calorie diet.
And that’s the kicker -- most people “going keto,” may not actually be following a true ketogenic diet since it’s hard to know for sure if your body’s in ketosis. Mancella explains that the only formal and valid method of determining if your body is in ketosis is if there are ketone bodies being excreted in your urine. “There are strips for purchase at local drug stores that are available to determine this,” she says. “Otherwise, we’re not actually sure if we’re in ketosis, and we’re just following a ‘low carbohydrate’ diet.”
In the first week, many people report headaches, mental fogginess, dizziness, and aggravation. Most of the time, this is the result of your electrolytes being flushed out, as ketosis has a diuretic effect. Make sure you drink plenty of water and keep your sodium intake up.6One of the fathers of keto, Dr. Phinney, shows that electrolyte levels (especially sodium) can become unbalanced with low carb intake.

Several comprehensive studies and meta-analyses have demonstrated that after a few months or even a year of a low carb diet versus a moderate/high carb diet, there are no significant differences in the amount of weight lost (2,3,4,5).  I will say, however, most of these diets are NOT keto and are simply lower carb (i.e. 20%).  Also, long-term effects (beyond 1 year) are not often studied due to budgetary constraints, so interpret results as you wish.

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.


I agree!! I too..have /had Diabetes II..at age 66 and retired RN, we were taught for so long the WRONG way to eat and I taught that way, the high carb, grains, etc, way to eat. KETO saved me. Dropped my A1C and I feel great. The author of this page is wrong when saying 5-10 percent of our diet, carb eating, should be root veggies like ‘carrots”…so wrong. For goodness sakes, get KETO right by educating yourself, Tammy Shiflet~ Horribly wrong! There are so many studies and physicians, brain scientists, etc out here who understand what this diet is about. Read, and educate yourself….Please! Diabetes is a symptom of the Government’s education mistakes. Sugar, Wheat, Grains…horrible for us. Get with it, we live in 2018 and the information is out there; if you need a list, just ask.
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.

The keto diet dates back to the 1920s, explains Michelle Hyman, MS, RD, CDN a registered dietitian at Simple Solutions Weight Loss. "The original keto diet was designed for patients with forms of epilepsy that were resistant to standard treatments. The macronutrient breakdown was designed to mimic the fasting state — which seemed to help with relieving seizures — yet provide energy and nutritions to function," Hyman says.
Tammy, just because someone follows a keto diet doesn’t mean they can’t have their sweet treats. There are dozens of websites with hundreds of keto sweet treats and “fat bombs” made with stevia or other natural non-caloric sweeteners which will not raise blood sugars. One of my favorites is Keto Mocha Mousse https://www.ruled.me/keto-mocha-mousse/ which has 5 g net carbs per servings. We don’t have to be deprived on keto.
At any given intensity, a keto-adapted athlete burns more fat and less glycogen than a sugar-burning athlete. Long-term elite keto athletes can burn up to 2.3 times more fat at peak oxidation and 59% more fat overall than non-keto athletes, and they do it at higher intensities. They remain in the predominantly fat-burning zone at 70% of VO2max, whereas non-keto athletes switch over from predominantly fat burning to a spike in sugar-burning at 54.9% VO2max.
On May 24, 2018, I had a 90-day follow-up appointment with my doctor. When he came to the exam room with my chart he immediately started to fist pump me with praise of congratulations, he was ecstatic. I am now at 233 pounds (106 kg)! I have lost 51 pounds (23 kg) and my girlfriend has lost 25 pounds (11 kg). I went from a 42-inch (107 cm) waist to a 38-inch (96 cm) waist. But, here’s the best part, my A1c came down to 5.7 and all my health markers have improved. He called me his poster child for being on the path to curing my Type 2 diabetes.

7. I should mention ALL my health markers have DRASTICALLY improved including cholesterol and inflammation markers? My fatty liver is resolving and my cardio markers are perfect! The study where you cited there were not significant changed in diabetes markers in two months, well it takes longer! Check it out at 6 and 8 months. Most people will show a VERY different story than what you are reporting!

Although many proponents recommend this high fat version of Keto for weight loss, it first gained notoriety as a treatment method for Epilepsy. Going as far back as the 1920’s, medical professionals have recommended high fat Keto Diets as a treatment method for difficult to control seizure disorders. However, a diet that includes a high percentage of fats as part of its eating program increases the daily caloric intake. More calories means slower fat loss. Therefore, the higher calorie count is why this Ketogenic Diet type is considered a slower weight loss model for dieters and is why the Ideal Protein Protocol is a more effective Keto Diet for weight loss.

Ketoacidosis most commonly arises with people with diabetes. Diabetic ketoacidosis occurs in response to a severe lack of proper insulin activity whereas alcoholic ketoacidosis is a harmful metabolic condition arising when someone consumes alcohol but no food, explains Michael J. Gonzalez-Campoy, MD, PhD, medical director and CEO of the Minnesota Center for Obesity, Metabolism, and Endocrinology, in Eagan, Minnesota. Either way, this is a dangerous situation.
The problem is the SAD diet (Standard American Diet) and eat less move more advice. Tell that to a baby boomer with a hi bmi. Keto if done properly allows over weight people a way to lose weight without having to do hours in a gym. It is recomended to do a 15 minute walk now and then to keep a level of fitness. The weight is coming off even if one doesnt excercise. No sugar highs and lows, no cravings of carbs. Easier to do intermittent fasting to break plateus. Having the control over food and not being a slave to it. Reduction in sugar levels. The chance of autophahy. No brain fog. The chance to reverse type 2 diabetes. We have an obesity problem world wide. Yes you do have bad breath. Yes you can get constipated. Shall I stop because of a couple of negatives. Both negatives are treatable. The keto wave is coming. Empowering people to take control of thier own bodies by controlling thier insulin levels by keeping all sugar derivied products to a low level. The food companies drug companies are worried.
The researchers hypothesized that the positive effects that the ketogenic diet has on migraines are due to how ketone bodies inhibit neural inflammation and enhance brain mitochondrial metabolism. The ketone bodies do this by blocking high concentrations of glutamate (commonly found in both migraine and epilepsy sufferers) and reducing oxidative stress.

A keto diet has shown to improve triglyceride levels and cholesterol levels most associated with arterial buildup. More specifically low-carb, high-fat diets show a dramatic increase in HDL and decrease in LDL particle concentration compared to low-fat diets.3A study in the long-term effects of a ketogenic diet shows a significant reduction in cholesterol levels, body weight, and blood glucose.

If you experience symptoms like fatigue, intense hunger and cravings, light-headedness, or heart palpitations, this may be a sign your blood sugar has dropped too low. Use a blood glucose monitor to track your body’s response to the diet change and make sure your body is adapting properly. If necessary consult your physician for necessary medication changes.
One study from 2005 followed 22 people with Type 1 Diabetes for 12 months. The difference here however is they consumed 70-90 grams of carbohydrates per day versus the restrictive less than 20 grams per day on the Ketogenic Diet. Remember my motto? Moderation is the key! The results were positive; less hypoglycemia, insulin requirements were reduced and their A1c dropped from 7.5% to 6.4%.
The trick to reaping the benefits of the keto diet is to stay in ketosis, which means keeping your carbs at 5% or less of your calories. The 5% can fall anywhere between 20-50 grams a day. However, if an insulin shot is missed while in deep ketosis, there’s a good chance you will find yourself quite sick, so it’s probably best to avoid the risk and keep carbs on the upper end of this spectrum.
I’m not Edward, but I’ve been on a keto diet for 3 weeks. I don’t find it difficult at all. I’ve attended 2 birthday parties, and it’s easy to say “No thank you” when I’m offered cake because my health is my top priority. Drinking a lot of water to support the kidneys is an absolute must. Also, supplementing sodium, potassium and magnesium keeps electrolytes in balance. A Naturopathic doctor is a great source of information on true lifestyle modifications.
ME: There is a sort of three-phase process the body goes through as it adapts to burning fat as its primary fuel. After two to three days, you will show elevated ketones [the buildup of chemicals created by the body when it burns fat for energy] in the blood. Energy will be low for the first week or two, but keeping electrolytes up such as sodium, magnesium, potassium [by using sea salt liberally and considering a supplement if necessary] and drinking water usually help. After about four to six weeks, the body actually makes more mitochondria [the powerhouses of our cells], and that is when your energy starts to soar. You also start seeing amazing mental clarity and focus, cravings go away more and more.
A well-balanced keto diet includes enough fat so that you are not hungry after a meal, can go for several hours without eating, and have ample energy. Make sure to increase your intake of fat at the start of your keto journey until your body adapts to using fat and ketones for most of its energy needs. Once you’re fat adapted, let your appetite guide you in cutting back on fat a bit until you reach the point where you can easily maintain the balance between hunger and satiety.
I am beside myself. I’m at the point that I’m afraid to eat anything. It goes right through me!! I’ve had liquid diarrhea for 3 weeks now and don’t know what to do. I’m up through the night and it’s really messing with my sleep. I have breast cancer and I really need to do this diet. I’m very worried. I have been taking psyllium husks but I’m afraid to go overboard. Is it ok to take that every day? Thanks you!
Originally developed in 1924 to treat epilepsy, the ketogenic diet has most recently rose in popularity as the latest and greatest miracle weight-loss plan. Additionally, proponents of the ketogenic diet—or keto diet, as it’s commonly known—advertise health benefits ranging from glucose control to treatment of Alzheimer’s. But, what does the research really show?
But wait, there’s one loophole. Have polycystic ovary syndrome (PCOS)? Then the keto diet may help regulate your periods. “Women with PCOS have high insulin levels, which cause sex hormone imbalances,” notes Yawitz. In a small study published in the journal Nutrition & Metabolism, subjects with PCOS following a ketogenic diet for six months noted improvements in their menstrual cycles — and a small number of women became pregnant, overcoming previous infertility obstacles. “This study was very small, so we can’t make recommendations for all women with PCOS based on its findings,” says Yawitz. “And really, any diet that leads to weight loss should help in PCOS.”
You’re a diabetic counselor and are talking about being worried about not being able to eat birthday cake? Hell I’ve been on keto since July 2016 and haven’t felt any urge to go back, simply because I feel so much better. Also the diet is really not all that restrictive, you can make desserts using stevia/erythritrol, coconut/almond flour, etc. I had ketogenic pizza the other night and it turned out great. Lots of great resources out there for food options. I’m not diabetic myself, but I used to be prone to hypoglycemia and keto has eliminated the issue since I’m not dependent on glucose. There are a lot of wrong ways to do keto though, and doing the diet correctly has a moderate learning curve.
Just this week, a 25,000-person study presented at the European Society of Cardiology Congress in Munich suggested that people on the lowest-carb diets had the highest risk of dying from cancer, cardiovascular conditions, and all other causes. Another study, published this month in the Lancet, also found that people who followed diets that were low in carbs and high in animal proteins had a higher risk of early death compared to those who consumed carbs in moderation. (The opposite was true, however, for low-carb dieters who opted for plant-based proteins over meat and dairy.)

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.
The level of total cholesterol showed a significant decrease from week 1 to week 24 (Figure 3). The level of HDL cholesterol significantly increased (Figure 4), whereas LDL cholesterol levels significantly decreased with treatment (Figure 5). The level of triglycerides decreased significantly after 24 weeks of treatment. The initial level of triglycerides was 2.75±0.23 mmol/L, whereas at week 24, the level decreased to 1.09±0.08 mmol/L (Figure 6). The level of blood glucose significantly decreased at week 24. The initial blood glucose level and its level at the eighth, 16th and 24th week were 7.26±0.38 mmol/L, 5.86±0.27 mmol/L, 5.56±0.19 mmol/L and 5.62±0.18 mmol/L, respectively (Figure 7). The changes in the levels of urea (Figure 8) and creatinine (Figure 9) were not statistically significant.

Instead of thinking about the total carbs you’re eating, assess what those carbs provide to you. Do the majority of your carbs come from fruit and vegetables, with a payload of fiber and disease-fighting antioxidants? Fantastic. Or are you consuming them in the form of added sugars (cookies, candy, soda) or refined flour? If you are, you know what to do.
Look for natural sources of electrolytes or take an over-the-counter supplement. “Avocados, leafy greens, asparagus, and cruciferous veggies are great for providing important electrolytes, says Josh Axe, DNM, DC, CNS, a certified doctor of natural medicine and clinical nutritionist. Dr. Axe also suggests a magnesium supplement to help you sleep and avoid cramps or constipation.
A typical keto diet is comprised of 80 percent fat, 15 percent protein, and a mere 5 percent of calories from carbohydrates. If you consume 2,000 calories a day, that means just 100 of them are coming from carbs—including healthy carbs like fruits and vegetables. When you eat this way, it triggers ketosis, which means your body has burned through all its carbs and needs to begin burning fat for energy.
The primary drawback of keto for the general population is how restrictive the diet is. “It requires more thought than some other diets,” Santos-Prowse says. And whenever a diet requires too much thought or effort, the likelihood of effectively sticking with it becomes diminished. People just don’t like having to think about how, when, and where to get their next meal when they’re so used to grabbing something quick from the nearest fast food joint.
They focus on what to eat instead of what not to eat, according to Dr. J. Michael Gonzalez-Campoy, medical director and CEO of the Minnesota Center for Obesity, Metabolism, and Endocrinology, who worked on healthy eating guidelines with the American Association of Clinical Endocrinologists, the American College of Endocrinology, and The Obesity Society.
Then in 1994, Dateline ran a story about Charlie Abrahams, a toddler with severe epilepsy whose parents turned to the ketogenic diet in desperation. It worked so well that Charlie was reportedly seizure-free (and drug-free) within a month. In 1997, Charlie’s father, Hollywood producer Jim Abrahams, adapted their story into the TV movie ...First Do No Harm, starring Meryl Streep. The saga of the Abrahams reignited interest in a ketogenic diet as a possible treatment for everything from migraines and sleep disorders to autism and Alzheimer's disease. In more recent years, with growing interest in the similar Atkins diet, keto started being touted as a weight-loss strategy, too.
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!
“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. 
The keto diet is a low-carb, high-fat dietary regimen which has been linked to improvements in insulin sensitivity and higher rates of weight loss — both positive factors in managing type 2 diabetes. Lowering carb intake induces a metabolic state known as ketosis, through which the body produces ketones which burn fat — rather than carbohydrates — for energy.
It takes more work to turn fat into energy than it takes to turn carbs into energy. Because of this, a ketogenic diet can help speed up weight loss. And since the diet is high in protein, it doesn't leave you hungry like other diets do. In a meta-analysis of 13 different randomized controlled trials, 5 outcomes revealed significant weight loss from a ketogenic diet.

You even have root vegetable and a picture of a carrot. Carrots are not part of a keto diet and as far as I have seen never were. They have 2 much sugar content and are discouraged except in very small amounts. Are you sure you tried it? Sorry. Great article in many ways but outdated in others. I don’t think people go into thinking they will “do it forever” How long can I last? I think that is missing the point entirely. So many people are getting their triglycerides down, losing weight reducing stroke possibilities lengthening their very lives. It is just not fair to not at least point out a few of these things as much as the risks you made sure to point out. albeit they are very important. How about the risks of not doing something? How about the list of people that found this and turned their lives around. Also, I know several people who have been doing keto for years.
And, it's important to recognize that both study teams acknowledge that as exciting as their findings seem, a large, randomized controlled trial is still needed to more closely assess a variety of components that may be contributing to the successes found in both studies before the findings can be recommended to anyone outside the study groups1,2  he says.
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….

So one study looked at the long-term effects of a keto diet in obese patients and after 24 weeks, patients lost weight, reduced their total cholesterol, LDL, triglycerides and increased their HDL. Another study conducted on 132 obese patients found that the low carb (keto) group lost more weight than the low fat group while improving biomarkers like decreased triglycerides, improved insulin sensitivity, and decreased fasting glucose. This all was confirmed in a 2013 meta-analysis, 13 RCTs (1,569 participants) found that patients assigned to a very low carbohydrate diet resulted in greater weight loss compared to those assigned to a low-fat diet.
After seeing thousands of patients now for years and from personal experience, I still believe it comes down to staying away from processed foods and cooking at home whenever possible. Eating a variety of fresh fruits, vegetables, proteins, and fiber. Also, cutting out any sugary liquid calories; staying away from sodas, juices and the infamous sweet tea! Keeping stress levels under control and incorporating exercise into your routine will also be key to breaking through challenging times when you are having trouble with continued weight loss.

It’s no secret that carbs—especially refined ones like sugary cereals, white bread and pasta, or sweet drinks—cause your blood sugar to spike and dip. So it makes sense that eating less of them can help keep things nice and even. For healthy people, this can translate to more steady energy, less brain fog, and fewer sugary cravings, Mancinelli explains.
Weight loss is the primary reason my patients use the ketogenic diet. Previous research shows good evidence of a faster weight loss when patients go on a ketogenic or very low carbohydrate diet compared to participants on a more traditional low-fat diet, or even a Mediterranean diet. However, that difference in weight loss seems to disappear over time.

To lower your heart risks while following a keto diet, be mindful of the types of fats you’re eating. “Most nutritionists encourage people to get their fat from heart-healthy mono- and polyunsaturated fats,” Urbanski says. So even though going keto may sound like a license to load up on bacon and butter, reach for unsaturated fats from foods such as olives, nuts, seeds, and avocados, and olive, canola, and nut oils.
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.
The study concludes, “The ketogenic diet appears to improve glycemic control. Therefore, diabetic patients on a ketogenic diet should be under strict medical supervision because the LCKD can significantly lower blood glucose levels.” Previous research has also shown that for patients with type 2 diabetes, long-term administration of the keto diet lowered body weight, improved blood sugar levels and can result in a smaller needed dose of antidiabetic medication.
Now, there’s even evidence that a low-carb, high-fat regimen (as the keto diet is) helps you live longer, compared to a low-fat diet. In a study by the medical journal The Lancet that studied more than 135,000 adults from 18 countries, high carbohydrate intake was associated with higher risk of total mortality, whereas total fat and individual types of fat were related to lower total mortality. Total fat and types of fat were not associated with cardiovascular disease, myocardial infarction or cardiovascular disease mortality.

Great article Doc! Question: One of the world top experts in high fat low carb diet, Dr Tim Noakes has stated that top level athletes actually perform better on keto, as himself an extreme marathoner , cured his type 2 diabetes by going keto. In the light of what we know today about keto, would you still assert that athletes shouldn’t adopt ketosis as their desired state?
Unlike some restrictive eating plans, the ketogenic diet actually has some wiggle room. Authority Nutrition highlights four different variations, which allow varying proportions of fat, protein, and carbs. No matter which variation someone chooses, they can expect to eat a lot of meat, fish, eggs, dairy, and nuts. It’s time to take a closer look at some of the health benefits of the ketogenic diet.
Nine most popular diets rated by experts 2017 There is a wide variety of diets for losing weight, gaining weight, or living healthily. This article looks at nine of the most popular diets based on how many articles cover them, how popular they are, and how much feedback we receive about them. Diets include the ketogenic diet, the Zone diet, and the raw food diet. Read now
In another study looking at ketogenic diets as a treatment for cancer,5 this research team concluded, “based on the results of rigorous preclinical and clinical studies performed thus far, the KD would appear to be a promising and powerful option for adjuvant therapy for a range of cancers. Cancer-specific recommendations await the findings of randomized controlled clinical trials.”
Even if you don't have a history with eating disorders, keto can still leave some people (although certainly not everyone!) with negative feelings around food. "For the vast majority of people, keto is not sustainable, meaning they don't stick with it for more than a few months," Brown says. "Not 'succeeding' with this diet and returning to one's usual eating habits can trigger feelings of guilt and failure." Those two feelings can actually trigger disordered eating in some people in the worst-case scenario, says Brown. (Also, We Seriously Need to Stop Thinking of Foods As "Good" and "Bad")
Although many proponents recommend this high fat version of Keto for weight loss, it first gained notoriety as a treatment method for Epilepsy. Going as far back as the 1920’s, medical professionals have recommended high fat Keto Diets as a treatment method for difficult to control seizure disorders. However, a diet that includes a high percentage of fats as part of its eating program increases the daily caloric intake. More calories means slower fat loss. Therefore, the higher calorie count is why this Ketogenic Diet type is considered a slower weight loss model for dieters and is why the Ideal Protein Protocol is a more effective Keto Diet for weight loss.
Here’s another controversial yet promising area of study: Research suggests that when patients with diabetes take on a low-carb diet (like keto), they experience improvements in insulin sensitivity by up to 75 percent, as well as a reduction in blood sugar control medications. What we aren’t sure of, however, is whether these improvements are due specifically to the effects of ketosis or to weight loss in general, so similar results could theoretically be found with any successful diet.
It’s best to approach this change in eating as a way to feel better and become healthier, rather than as a “fad diet” or weight loss quick-fix. Dr. Cabeca recommends giving it six months to test the effects, keeping in mind that some trial and error is expected along the way. The diet should ideally be approached in step-wise fashion, focusing on alkaline first before adding in fasting and the keto aspect.
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.
A growing body of research is finding that behind many psychiatric and neurological issues — such as bipolar disorder, epilepsy, migraine — are malfunctions in the work of sodium, potassium and calcium ion channels in brain neurons, which pass the electric charge between nerve cells. As noted above, two thirds of the brain’s energy is used to help nerve cells “fire,” or send signals between cells. Another nerve cell signaling chemical (neurotransmitter), called GABA (Gamma-aminobutyric acid) has also been found to be disordered in bipolar, epilepsy and schizophrenia. A 2017 genetic study also found common genetic and biochemical pathways between bipolar disorder and epilepsy that create “excessive circuit sensitivity” in the neurons of both conditions.
Yancy has seen similar results in his practice. “Carbohydrate intake is the main driver of blood sugar. So if you’re able to lower blood sugar by reducing carbohydrate intake, then you may be able to reduce diabetes medication,” he says. “We’ve seen people come off of hundreds of units of insulin just by changing the way they eat, and that can happen really quickly, in just a few weeks.”
Type 2 diabetics may be on a range of medications that only treat symptoms, have serious side-effects and leave root causes unaddressed. Medications like Metformin may still make sense to use while reversing diabetes with a ketogenic diet. However, most if not all drugs like insulin and sulfonylureas can and should be discontinued. A note of caution though, changing doses or discontinuing medications is something you should do with the help of your doctor (or at the keep them informed).
Parkinson’s Disease Because these patients are at a higher risk for dementia, researchers like Robert Krikorian, PhD, professor of clinical psychiatry and the director of the division of psychology at the University of Cincinnati College of Medicine in Ohio, are studying how inducing nutritional ketosis may be used to preserve cognitive functioning.
The low-carb diet induces ''nutritional ketosis," Dr. Saslow tells EndocrineWeb, which is not the same as ketoacidosis. Ketones are a chemical your body produces when you burn stored fat; if you are on a low-carb diet you may be ''in ketosis.'' Ketoacidosis is different; it is a life-threatening condition in which levels of ketones and blood sugar are dangerously high, which may occur in people who have poorly controlled diabetes.
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.
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. 
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.

WOW. I guess I must be a very special, highly motivated patient then. I, of course, would never have said that about myself. My high motivation is trying to get over the hatred of food that being Diabetic gave me. I don’t feel that way anymore, and am finally happy cooking, again. (My doctor DID tell me exactly that, BTW. Even to the extent of telling me to not include the tsp of agave that I was having in my coffee once a day because sugar is sugar.)
Ketoacidosis most commonly arises with people with diabetes. Diabetic ketoacidosis occurs in response to a severe lack of proper insulin activity whereas alcoholic ketoacidosis is a harmful metabolic condition arising when someone consumes alcohol but no food, explains Michael J. Gonzalez-Campoy, MD, PhD, medical director and CEO of the Minnesota Center for Obesity, Metabolism, and Endocrinology, in Eagan, Minnesota. Either way, this is a dangerous situation.
I am curious about what has been referred to as “keto rash”. I decided to shift from a GAPS Diet to a ketogenic one. I wasn’t tracking my carbs specifically and was doing well. Then I developed this rash on various parts of my body. I originally thought it might have been either pecan or MCT (C8) that I started having, but I have eliminated both of those. Then I did some research and realized that others have also experienced this rash after starting a strict Ketogenic Diet. There are a few solutions running about–most of which include introducing carbs at higher levels. Antibiotics were also listed. Anyway, I was wondering if you have run across this type of rash as it relates to starting a low-carb diet? Any thoughts, Dr. Jockers?

My son started the Keto Diet (not perfectly) with the ok of his Dr and a Different Oral Chemo at the same time. Last Tuesday an MRI indicated no new growth or no new tumors. We don’t know if the new Chemo, Keto diet, lots of prays or what has stopped the tumors from growing.I found your site after looking for possible adverse reactions to Keto Diets, and appreciate your research. His platelets are low now and never have been low before. This is stopping the next Chemo treatment. I understand that being on Chemo for 12 months could have created the low platelets and now the possibility that the Keto Diet could also be causing low platelets is frustrating. They will do a new blood test Tuesday to see if the platelets have increased. Any suggestions about how if possible to increase the platelets on the Keto Diet would be helpful.


The initial weight loss is usually short-lived as carbohydrates hold onto fluid in the body. Beyond that, we need fat on our bodies in order to function and survive. Fat is essential and plays a vital role in many basic physiological functions of our body. This notion of ‘burning’ as much fat off our bodies as we can can be downright dangerous because biologically, we need fat. Having too little body fat can lead to issues such as:
Our bodies run well on glucose (carbs)–they give us the necessary energy we need to function on a daily basis. When our body doesn’t get enough glucose (either because we’re cutting carbs too low, OR we haven’t eaten in too long), our body kind of freaks out and looks for other forms of energy to satisfy that role. That’s where the fat comes in. Without carbs, our insulin levels drop and fat is released from our cells. The fat overwhelms the liver which turns it into ketones, our body’s second choice to carbs for energy.

The keto diet is an ultra-low-carb and high-fat diet that restricts total carbohydrate numbers to just 20 or 30 net grams of carbohydrate per day. That’s the equivalent of a single piece of fruit or half a bagel. When you cut carbs, your body’s preferred source of energy, you require your body to suddenly shift to fat for fuel. This raises blood levels of ketones and puts you in a state of ketosis—hence the name “keto diet.” Once this shift, happens, you will lose weight, but you may also have experience so negative side effects. This is commonly referred to as the keto “flu.”
Unless you’ve already been eating a paleo or primal diet and are somewhat keto-adapted (burning ketones for fuel), it is a good idea “reset” the body in order to regain the metabolic flexibility to go into ketosis or even stay in ketosis despite eating some carbohydrates. Intermittent fasting is one efficient way to do this. During a water fast, ketosis can occur in days instead of weeks or months and often sustains for a while after the fast.
This general “muscle wasting” assertion often comes from trainers and dietitians who really have not studied the science on muscle preservation. They will tell you that the brain requires at least 100 grams of carb per day and if you don’t get those carbs in the diet, your body will break down your muscles to get it. This is true when one’s diet is high carb, and no ketone bodies are available as an alternative source of brain fuel.

Related to this research, some serious attention has been given to ketogenic dieting and Alzheimers Disease. Scientists have discovered increased cognition and enhanced memory in adults with impairments in these areas, and a growing body of research shows improvement at all stages of dementia. Ketosis has been shown to be effective against Parkinson’s disease as well.

Either there are very few participants in the studies, they don’t have an even number of males vs. females, or they don’t last but a few months. One study only looked at 28 people; only 21 completed the study and 20 of these participants were men. On top of this, they were only followed for 16 weeks. Okay, so we see that 20 men can limit their carbohydrates severely for 4 months and lose weight which automatically makes their A1c come down. Great! So, the real question is, how long can these 20 men stay on this diet for the rest of their lives? How long would you like to go without eating any fresh fruit? I’m craving some now, so I’m taking a break to go grab a snack now!

During ketosis, your body produces ketones, or byproducts of the fat-burning process. Your body uses several tactics to remove the ketones from your body, including exhalation. When ketones are excreted by your lungs, they leave as foul-smelling acetone. Because of this fat-burning process, you may develop bad breath while you’re in ketosis. Drink plenty of fluid to help your mouth stay hydrated and reduce the risk for bad breath. If the situation becomes particularly smelly, you can turn to sugar-free mints or gum to mask the situation.
Since carbohydrates do increase insulin and insulin is a storage hormone many people have made large leaps of logic to point the finger at carbohydrates as the primary cause of fat gain and obesity as opposed to overall caloric intake. They also point out that in a keto diet, carbohydrates are not being used as fuel hardly at all whereas fats become the primary fuel.
Thank you for this comment. It is truth! I keep telling people about this diet. It is literally the best diet I have ever been on. I can eat good food, I feel full, my weight is dropping, I feel better and I can actually feel the difference. While it is great for a professional to be skeptical of emerging diet trends (and lets face it, most diet trends are garbage peddled by snake oil salesmen), this one actually has science from some prestigious institutions behind it, not a marketing scheme.
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.  
The alluring promise of the keto diet, potentially filled with as much bacon, butter, eggs, and avocado as you can eat, sounds like the grown-up version of scoring a golden ticket to Willy Wonka’s Chocolate Factory. I mean, who wouldn’t want to chow down on bacon and butter at every meal? Especially if you ended up dropping a few pounds along the way?
Examples include non-starchy fruits and vegetables such as leafy greens, mushrooms, bell peppers, and berries. The trace minerals and vitamins found in grains can also be obtained at higher percentages in good-quality meats and dairy products. Moreover, compounds such as phytates and tannins in grains hinder the bioavailability of several minerals.13
Depriving the body of dietary carbohydrates for a period, long enough to deplete the body of its glycogen reserves, produces a ketogenic state. This depletion typically takes three to seven days to occur. During this time, you will notice that your energy level becomes consistently diminished as your body consumes energy with no new source of fuel added. You will also find that you begin to drop water-weight, as glycogen is bound to water and then excreted.
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. 

Early humans probably were on an LCHF diet. But when did humans become the “intelligent” species that they are? Can that be related to invention of agriculture? When humans began settling down on river banks to grow their crop, be it rice or wheat or maize, may be the rich alluvium, elevated mineral contents and higher glucose levels associated with grains might have given them increased brain activity leading to their cultural and intellectual development. My only worry is, this”new found” ketogenic diet shouldn’t push us back to stone age, though on a positive note, that might save our planet from anthropogenic destruction!
