  1. Dr Hyman thank you for doing these videos. I want to ask why most insurance companies will not pay for us to go to a functional medicine doctor. Here in The Tucson AZ area functional medicine doctors don’t take insurance and are concierge doctors. What are doctors doing to change that so we can have true health or is it just the money like so many other things in medicine are? Why are doctors moving away from caring for us?

  2. I have been doing ketogenic diet, when I started I was 60 pounds heavier and my A-1 C was 12.5 now I am just at 200 pounds I’ve lost 60 pounds in my A-1 C is it 5.6 I don’t even need insulin the other health benefits aside of lowering my blood pressure improved improved cognitive function just for the blood sugar affect only do I recommend this to anyone with diabetes type two .many doctors do not like it because they don’t get the insulin sales they used to .all kidding aside ketogenic diet deals with insulin resistance ,not putting a Band-Aid on a broken spine. But fixing the problem and all of the cascading other issues the insulin resistance brings with it I have been on every other diet known to man they all made me lose some weight but they were impossible to stay on and none of them zero not one touched my blood sugar issue .

  3. Ur oversimplifying the case, fat is not the enemy, and neither is carbohydrates. The ketogenic diet is a fad diet created by marketing, that will eventually fade. ANIMAL meat, Dairy products, cheese, bacon and egg are classified as carcinogens..Yet these are foods that dominate a keto diet..Saturated fats and cholesterol are the main culprit in heart disease and hypertension and yet ur promoting a diet high in fats..This is not sustsinable..Why mortgage ur body by doing keto, and fasting, when u can go to a plant based diet and get all the benefits without the hassles of starving urself..U dont need to be in ketosis to be healthy,syop misleading people by promoting a diet obviously funded by the meat and dairy industry…Not for everybody? But u guys are promoting it for every body..No, .You cant seriously do a vrgsn diet by being keto at the same time..Based on meta anslysis, the long term bad effects of keto like coronary heart disease and artheriosclerosis, far outweighs the short term benefits..BESides,not only does keto cure the top 15 killer disease, it enhances most of these chronic ailments like cancer.. Define carbohydrates? fibers are carbohydrates and yet ur saying eating bacon and fatty meat are healthier??? Cut the crap..Your the one confusing the science….

  4. I wish Mark had occasionally looked at the interviewer instead of only addressing the camera. It looks real uncomfortable for the interviewer and watching was uncomfortable for me. He's not giving a lecture or a talk so he comes off as dismissive of her once the question is asked. I've never seen him not engage with an interviewer in any other video.

  5. For those of us who love the topic of health, ketogenic diets, overall feeling of wellness, and all the like…. but keto just feels awful!!!! You’ve mentioned some people don’t do well on keto. How do we make it work for us? If there’s no way, what is the next best thing? I already eat almost all whole food items with an every now and then tortilla or something. I just can’t shake the headache on keto.

  6. At minute 15 the statement regarding the health benefits for a person suffering from T2D is profound. I am on Keto and have lost weight and have checked my blood…I am still on statins however….I'd like to come off of them but will need to try it with my doctors supervision. I'd love to hear what you think the acceptable ranges for HDL/LDL etc., would be considering the perspective that the Keto diet has turned the food pyramid upside down…are our target numbers for HDL/LDL also a bit out of date with reality?

  7. I am 81 years old. In 1957 I had an autoimmune event. I have reactive hypoglycemia (see, no ads, no promotion). In 1964 I took a glucose tolerance test. The dumb specialist said I was prediabetic. Boy was he wrong. I took the test because I had all the symptoms of episodes of very low blood sugar. My test showed me that I was getting them 3 1/2 hours after eating too much sugar/starch/alchol. i modified my diet but not enough. About 16 years ago I put myself on a sever low carb diet. With this diet most of my symptoms slowly cleared but I gained weight. I was not eating a ketogenic diet. With that my weight would have ballooned. I cut the fat in the diet and lost weight. About 3 years ago I figured out what must be happening. Among the things it explained why women with my genetics get gestational diabetes. Why we do not lose weight on a low carb diet (unless we starve). What actually causes type 2 diabetes. See

  8. How about whole food plant based?? Much better, and a lot more research behind it, and isn't super unsafe and unhealthy, like keto is. Keto is not good for you; it creates intramyocellular lipids increasing which just increases insulin resistance… gosh. Y'all have some of the best plant-based docs there (Esselstyn) with years of research as evidence for those ways of eating, yet you guys keep pushing fad stuff… but keto will keep those cardiologists in business 😉

  9. Hello I'm cambell by name, I'm giving a testimony about Dr.Abumere the great Herbalist, he has the cure to all manner of diseases, he cured my herpes disease, though I went through different website I saw different testimonies about different spell casters and herbalist, I was like: 'Many people have the herpes cure why are people still suffering from it?' I though of it, then I contact Dr. Abumere via email, I didn't believe him that much, I just wanted to give him a try, he replied my mail and Needed some Information about me, then I sent them to him, he prepared it (CURE) and sent it to Airfreight Online Courier Service for delivery, he gave my details to the Courier Office, they told me that 3-5 days I will receive the package and i took the medicine as prescribed by him and I went for check-up 2 weeks after finishing the medicine, I was tested herpes negative, if you are herpes positive do me a favor for you to contact him and I will try my possible best to make sure you get cured, when you contact him, make sure you tell him that I referenced you.. contact him via: [email protected] or WhatsApp +2349021975055
