He has been on keto diet for at least 3 years now. I think that he is some proof that yes, it does work. And it may be that some people do need keto. However, I don’t believe that everyone needs keto diet to get reversal. I have had reversal with regular ADA diet in my clinic. Not just a few! Many have reversed. However, I just want for keto dieters to find a clinical trial. We do need more information. We must understand what happens in the long term on keto diet. I personally did Atkins years ago, which was 20 grams. I had a very hard time to stay on it. I lost 20 pounds, and then I did gain it back. I just could not live without some more carbohydrates than this allowed. I don’t know about being on 60 to 70 carbs, and staying in ketosis. It seemed I was out of it at 22 carbs. Anyway, this was not for me. Maybe it is for you. No one is saying that one should never go on a keto diet, but we are wary of it. We need more science behind it. Therefore, I am just going to put this out here now. I will paste it down the page so that others may see it. They are taking participants. If you fit the criteria, please help us to get more than people’s opinion about this diet. Then we can be more positive about it, and recommend it if the science is there. Here is the link to the clinical trial. Thanks for your comments:
Using the Bulletproof Diet, including Brain Octane Oil every day for long periods of time, and eating carbohydrates some of the time but not always, avoiding inflammatory foods, and using Bulletproof Intermittent Fasting, I was able to recently test with perfect insulin sensitivity — I scored a one on a scale of 1 to 120 (see my numbers below). I also had above average glucose tolerance. That’s metabolic flexibility by the numbers!
Some people have trouble with the concept of high-fat and a moderate amount of protein. I have to admit. It was hard for me to wrap my head around it at first. Now I have even given up artificial sugar substitutes and diet products of any kind. It's even hard for me to call this a diet. After researching this eating style, I've learned it's a way of life.
With the high intake of fat, are we concerned about the high intake of cholesterol? YEP. A study using the keto diet as a form of treatment for epileptic seizures in children found that after 6 months of administering the diet, triglyceride levels increased, total cholesterol levels increased, and HDL and LDL increased. These results suggest that over time, a keto diet may lead to an increased risk of hypercholesterolemia and hypertriglyceridemia. In the same ten-year study, 40% of patients developed hypertriglyceridemia and 29% of patients experienced hypercholesterolemia. So, if heart disease runs in your family, you may want to bow out now.

I must tell you when looking at this link they say the American Diabetes Association Guidelines call for 60-75 carbohydrates per meal and that is simply not true. 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.
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.
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.

Common complications of diabetic ketoacidosis include very low blood sugar, or hypoglycemia, and swelling of the brain (cerebral edema). As such, when a person is in ketoacidosis, there is such a high level of ketones produced that can push a person into cardiac arrest (heart attack) or kidney failure. Hence, the very important reason for taking occasional keto breaks go give your body a bit more nourishing carbs. 
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.
The fact is that compared to many vegetables, fruit is actually a pretty poor source of vitamins and minerals.  And grains?  Not only can the trace vitamins and minerals in grains be found more richly in meats, dairy and other keto friendly foods–there is speculation that phytates and tannins found in grains can block absorption of some vitamins and minerals.
Also, to the author I do appreciate you stating you are bias up front, but I do get to indulge with some fruit/berries when I want. You dont give up everything forever but you learn to fit them into your macros. I have learned to make Keto ice cream and fat bombs if the urge comes along. I have learned to take keto friendly foods along to potlucks that everyone loves. Keto can be a way to follow forever but everyone has their own needs for their bodies. I am new to this but finding it easier and easier to remain keto

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.
This is ALL so confusing and overwhelming. I am not diabetic. I am trying to be proactive about it. I am borderline obese (by US standards) and obese (by Asian standards). I am 50 years old. I was addicted to fat and sugar (especially combined!) through my teens and twenties. I decided to get healthy in my 30s, so I became a Vegan (but an unhealthy/careless one, so my weight yo-yo’ed a lot in my 20s and 30s). In my 40’s I reintroduced animal products into my diet and a number of my health issues went away, but I am still fat. I am considering Keto/Carnivore, but I am concerned that I may just be falling prey to more extreme diets which could set me up for problems (e.g. diabetes) down the road. I guess I am what most would refer to as pre-diabetic (metabolic syndrome). Should I try keto or am I taking too much of a risk?
Roxy, I started at 283 in February 2018. I am now 212 with the hope to make 100lbs lost by Feb 2019. KETO is a life choice and comes with changes that have to be made! My mantra at difficult times in the beginning was to be different i must do different! Also most modern foods pizza and tacos can be adapted to keto way of eating. Just takes research and a little planning. I have tacos weekly!
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.

In 2006, Czech researchers placed men on either a diet containing red meat or one without red meat, then had them sweat. Women smelled and rated the sweat. Across the board, the red meat dieters produced less attractive body odor. When they had everyone switch to the other diet, the results persisted: Those who had switched to a no-red meat diet produced better-smelling sweat.
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.
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.
