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.
You say keto is a highly controversial topic. For those of us following a keto diet, there is no controversy whatsoever because the diet proves itself efficacious very quickly. I think the real controversy comes in because the ADA has been recommending dangerous levels of carbs for decades now, and they would lose face if they had to change their recommendation and admit they’ve been wrong for so long. You say there are not many studies on the keto diet, and I disagree with you. You’ll find the evidence if you look for it. Eric Westman, Steve Phinney, Jeff Volek and many other researchers have written volumes about this.
Your glycogen stores can still be refilled while on a ketogenic diet. A keto diet is an excellent way to build muscle, but protein intake is crucial here. It’s suggested that if you are looking to gain mass, you should be taking in about 1.0 – 1.2g protein per lean pound of body mass. Putting muscle on may be slower on a ketogenic diet, but that’s because your total body fat is not increasing as much.5Note that in the beginning of a ketogenic diet, both endurance athletes and obese individuals see a physical performance for the first week of transition.
This type of information has also been on the Internet. When I first saw what the consequences could be if this is planned by the person following the Keto diet as being for a lifetime thing, I immediately sent the article to my brother & his wife . They’ve been on this for some time & have lost weight on it. All good, but may not be well for my brother, who has one kidney. It was removed because it was no longer functioning at full capacity.
My pick for the healthiest meal plan for diabetes? My favorite is the Mediterranean Diet. It’s high in fiber, low in saturated fats and includes no processed foods which is the challenge for all of us at this point in history. If we could all eat like they do in Italy and Greece! Think of Sicily and the coasts of Greece where their diet consists of fresh fish, fresh fruits and vegetables, nuts, beans, seeds, olives and olive oil, lean meats such as chicken and pork, some eggs and little red meat. The American Heart Association recommends it as well as the American Diabetes Association as being one healthy diet choice for people with diabetes.
I have been a type 1 diabetic for most of my life. I live a very active lifestyle of long distance running and hiking. I’ve always had a very healthy diet, but would still have those after meal blood sugar spikes that would leave me feeling unwell. I decided to try the keto diet to see how my blood sugar did It’s been amazing. I’ve cut my insulin in half and my head is clear. I no longer have the brain fog. I sleep better and have more energy. I have been doing it for a year and have no desire to go off of it.
Another organ that plays an essential role in blood sugar regulation is the liver. It stores excess glucose as glycogen, and when glucose levels are low, glycogen is broken down to provide glucose [6]. This process is regulated by two hormones: insulin and glucagon. Insulin normally promotes glycogen synthesis and interferes with glucose release from the liver.
Although studies have shown that the keto diet can reduce seizures for children with epilepsy, there is no evidence indicating that keto helps with other brain disorders or improves mental cognition, according to Harvard Health Publishing. Some studies show that keto may lower blood sugar for people with type 2 diabetes, but there is not enough long-term research to determine whether it’s safe and effective for diabetics.

Eating cholesterol has very little impact on the cholesterol levels in your body. This is a fact, not my opinion.  Anyone who tells you different is, at best, ignorant of this topic.  At worst, they are a deliberate charlatan. Years ago the Canadian Guidelines removed the limitation of dietary cholesterol. The rest of the world, especially the United States, needs to catch up.


Holy cow Batman i started keto diet on the 9th of January within 4 days I was no longer on bydureon (weekly insulin) levemir 60units 2x daily and no more Novolog 25 units3x daily all that and metformin 10002x and this all didn’t have my sugars under control amazingly keto diet got sugars in check within four days I’ve been on diet now for 15 days and have honestly never fealt better I’m still green on diet and have had some issues while my body is healing itself (keto flu,low electrolytes very sluggish) ..

High-protein ketogenic diet (HPKD): This version of the keto diet is often followed by folks who want to preserve their muscle mass like bodybuilders and older people. Rather than protein making up 20 percent of the diet, here it’s 30 percent. Meanwhile, fat goes down to 65 percent of the diet and carbs stay at 5 percent. (Caution: folks with kidney issues shouldn’t up their protein too much.)
I’m desperate to find some answers~I have no history of sensitivity to anything, no allergies. I understand allergies can happen at any time. I started the Keto diet and in a one month time I had four separate episodes of my tongue swelling~each episode worse than the one before. I LOVED this diet~felt great, handled it with ease. The last episode almost put me in the hospital~my tongue was so swollen it was coming out of my mouth making it difficult to swollen and breath. I had no choice but to narrow it down to Ketosis. All the foods were the same that I have eaten all my life. No new meds. The last episode I took 2 Benadryl and pulled myself out of Ketosis with consuming a Dr.Pepper, and 2 pieces of white toast. I was terrified. Everyone on Facebook in all these Keto sites tell me it has nothing to do with Ketosis….but I’ve tried literally everything I consumed when a was on that WOE and I’ve had no reaction in days. My body feels horrible, I have no energy, my entire body aches. I want back on the Keto diet because my body was responding really well to it~except for my tongue.

All in all not a bad article. Not going to get into real specifics but like many “trendy diets” some of your claims, despite your applauding effort to site seemingly legitimate sources, are simply inaccurate. First of all MDs are not Nutritionist, they specialize in medicine. Holistic Health coaches specialize in Herbs and using the body to heal itself. Nutritionist/Dietitians focus on proven legitimate evidence to support claims of a basic diet consisting of all 5 food groups for living a healthy lifestyle. Can you live a healthy lifestyle outside of eating the 5 food groups, sure; but you better be well versed on preparation for attempting it. Truth is, any diet, and I mean any reputable diet, on the market can and will work if followed correctly. However, since the beginning of time, civilization has ate wheat as its primary food source and in fact it is still the primary food source worldwide. To eliminate it or complete-whole grains entirely is usually not wise for long term sustainable benefits. Coconut oil is terrible, period. Please never give that advice again. Saturated fat in any form causes arteriosclerosis, cite any heart health clinic or organization in the world for that evidence. Also through starvation, which can occur if the body consistently lacks its basal metabolic needs can and will develop ketoacidosis in a perfectly functioning pancreas. Basically meaning ketosis can develop into ketoacidosis. Again, just trying to provide some further information and clean up your claims. I feel you did a pretty good job touching on a lot of questions/concerns most people have with Keto diets. Like I said, I’m not selling my diet or anything for that matter. I simply want people to realize anything you do requires work, effort and discipline. All in all, it seems more people jumping on the Keto bandwagon are looking for quick results and should be well advised, as you mentioned, on the proper way to eat the right combination of food groups to prevent further deterioration. The right fats, greens and complementary proteins for BCAAs and so on. Truth is a long term Keto diet has not been studied enough to really know if the body is suffering damage long term. At the end of the day moderation, variety and a balanced lifestyle of diet and exercise in combination with the holistic approach (Physical, emotional, spiritual and societal well-being) is the key to long term vitality. Its your lifestyle, not diet that affects your health.
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.
Also, as I believe is mentioned, this diet has been around for along time and was the only way to treat diabetes. And some people did die. However, people still end up dead from t2d even after all the diet advice from educators and with all that pharmacy has to offer. An industry which gains nothing if people just choose to eat less. But has lots to gain if we just keep taking the tablets.
To get into and stay in ketosis, you must restrict carbs and sugar – less than 50 grams per day. This initiates your body to burn the remaining carbohydrates present, after which it moves on to stored glucose (glycogen), and finally it taps into ketones. Ketones are produced by the liver and readily used by the body for potent energy production and critical brain-related functions.
"Muscle loss on the ketogenic diet is an ongoing area of research," Clark told Everyday Health. "Small studies suggest that people on the ketogenic diet lose muscle even when they continue resistance training. This may be related to the fact that protein alone is less effective for muscle building than protein and carbohydrates together after exercise."
Ketosis: What is ketosis? Ketosis is a metabolic process, and it involves the body burning stored fat instead of glucose. Some people try to induce this with a low-carb diet, which can be healthy. However, ketosis also produces acid, and high levels of this can cause severe complications, especially for people with diabetes. Learn more here. Read now
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.”

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 many physiological reasons for eating enough carbohydrates throughout the waking hours to maintain a steady blood glucose level…a couple of important reasons are to minimize the hepatic release of glucose (from the liver) and to help prevent hypoglycemia which can be very dangerous and lead to hypoglycemic unawareness over a short period of time. Each person is different of course..if you aren’t taking insulin, or pills that lower your blood glucose levels, you may not have to worry about low blood sugars. The reality is, most people with diabetes do; it can be very dangerous for some to not get enough carbohydrates at each meal.


Dr. Campos, it is so discouraging to see that you disparage the ketogenic diet based on your assumption that it is very heavy in poor quality processed meats. No diet that relies on processed foods can be viewed as “healthy”. Become better informed by getting up to speed with what Jeff Volek, RD, PhD, calls a “well-formulated ketogenic diet.” Also, learn more about the potential of the diet to slow cancer progression (my specialty). You owe it to your patients who are depending on you for advice. Present them with facts, not opinions.
This effect can also be demonstrated by researchers at Kraft Foods, published in the American Journal of Clinical Nutrition. For 12 weeks one group ate a low fat, calorie restricted date, and the other ate a low-carb, high-fat diet without restriction… other than low carb of course. After 12 weeks, the low-fat group lost 5.5 pounds and the low-carb group lost 10.8 pounds.
Given all the buzz, adopting a ketogenic diet may be the perfect weight loss plan, especially if you have diabetes, or want to try this approach to lose those troublesome extra pounds. After all, it’s a very low-carb meal plan that promises effective weight loss while also lowering your blood sugar to the point where you could possibly stop taking medication. By all accounts, the “keto” diet, as it’s widely known, may even reverse type 2 diabetes, at least for some lucky individuals.

Keto cycling is a way to cycle in and out of ketosis while enjoying a more balanced diet on your "days off." One keto cycling approach includes five days of traditional keto diet and two non-keto days per week. Some people choose to save their off days for special occasions holidays, birthdays, and vacations. For best results, eat wholesome carbohydrate-rich foods on your off days, including fruits, starchy veggies, dairy products, and whole grains (rather than added sugars or highly-processed fare).
In a recent study in the Journal of Sports Medicine and Physical Fitness, Weiss and his colleagues found that participants performed worse on high-intensity cycling and running tasks after four days on a ketogenic diet, compared to those who’d spent four days on a high-carb diet. Weiss says that the body is in a more acidic state when it’s in ketosis, which may limit its ability to perform at peak levels.
WY conceived, designed, and coordinated the study; participated in data collection; performed statistical analysis; and drafted the manuscript. MF assisted with study design, performed data collection, and helped to draft the manuscript. AC analyzed the food records. MV assisted with study/intervention design and safety monitoring. EW participated in the conception and design of the study, and assisted with the statistical analysis. All authors read and approved the final manuscript.
The low-carb, high-fat approach to the keto diet limits the types of foods you can have, and entire food groups are eliminated entirely. Beans, legumes, and whole grains are out, as are many fruits and vegetables. Many of these foods carry vitamins, minerals, and other nutrients you can’t get from any other source, and without them, you may start to experience nutritional deficiencies.
As ketosis begins, your body will start dumping its stores of glycogen, a substance in your fat and muscles that carries excess weight. This will increase how often you urinate and can lead to an inevitable loss of electrolytes, Dr. Rahnama says. Electrolytes are essential to cardiac function and normal heart beating. “The loss of electrolytes, such as sodium, magnesium, and potassium will put the dieter at risk of a cardiac arrhythmia,” Dr. Rahnama adds.

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.


Twenty-one of the 28 participants who were enrolled completed the study. Twenty participants were men; 13 were White, 8 were African-American. The mean [± SD] age was 56.0 ± 7.9 years and BMI was 42.2 ± 5.8 kg/m2. Hemoglobin A1c decreased by 16% from 7.5 ± 1.4% to 6.3 ± 1.0% (p < 0.001) from baseline to week 16. Diabetes medications were discontinued in 7 participants, reduced in 10 participants, and unchanged in 4 participants. The mean body weight decreased by 6.6% from 131.4 ± 18.3 kg to 122.7 ± 18.9 kg (p < 0.001). In linear regression analyses, weight change at 16 weeks did not predict change in hemoglobin A1c. Fasting serum triglyceride decreased 42% from 2.69 ± 2.87 mmol/L to 1.57 ± 1.38 mmol/L (p = 0.001) while other serum lipid measurements did not change significantly.
