Dr. Michael Greger gets fact-checked by MD PhD doctor (debate)

Published 2022-12-05
Do Dr. Michael Greger´s views on diet and health match the science? A TV debate with Dr. Michael Greger covers heart disease reversal, animal and plant protein, diabetes etc. A critique of Dr. Greger´s claims.

We got a ton requests from you to comment on Dr. Michael Greger. This week viewers sent us a new video with dr. Greger, let’s take a look

It´s a tv show, Greger is in a debate. Greger will argue the vegetarian diet. Reversal of heart disease. Dr. Esselstyn and the Ornish trial.

Ornish trial: diet, stopping smoking, stress management (meditation etc), exercise

Many diets “reverse” diabetes, normalize glucose. low fat diets can reverse diabetes, low carb diets can reverse diabetes. elimination diets cut junk food, weight loss improves glucose

overt deficiency of protein or kwashiorkor virtually nonexistent in the west. we can avoid overt deficiency and not be at optimal level. true: main threats are diseases of excess. Heart disease, obesity, diabetes, even cancer: diseases of eating too many calories, too much of the wrong foods

Red meat intake reduced, diabetes went up. People eating more calories and more junk food. red meat not the cause of this rise in diabetes but red meat could raise risk of diabetes. reduction of red meat and even bigger increase of refined carbohydrates, overall more calories, risk of diabetes goes up but in theory both foods could be diabetogenic

does not imply more diabetes due to less meat

  • 25 years ago at age 55 I had back to back severe heart attack soon diagnosed with heart failure and given less than two years to live I went plant base diet now I am looking forward to celebrating my 80 birthday soon.
  • @slaffkas
    I can tell you one thing... I am over 50, plant based for 6 years after my heart surgery, and my cardiologist loves it. Prediabetis is gone, blood work is excellent. That is all I need. I am physically active as well.
  • I am an Interventional Cardiologist. I have observed so many of my patients who strictly follow plant based diets regressed their plaques on their follow up CT scan and Coronary Angiography. Well less moneys for an Interventional Cardiologist but good for them. Therefore so many cardiologists are reluctant to advice such diets which not only decrease the plaques but also doctors income. LOL.
  • @pravoslavn
    MY STORY: Twenty-five years I was on crutches due to crippling gout and my physician had me on kidney-destroying Alopurinol. The Internet had just come around and we were becoming able to educate ourselves beyond just what our physicians told us. I "went vegan" and started using Turmeric daily (slightly cooked in olive oil + a little black pepper.) In six weeks, I was off the Alopurinol, lost a bunch of weight, my BP and cholesterol numbers went down, and now, at age 78, I am healthy as a horse and have no more inflamatory symptoms or pathologies of any kind. My Doctor was scandalized that I had thrown away his medicine, but later, when his own mother was laid low with arthritis, he asked me to write for her an essay on how I had treated myself with Vegan diet + Turmeric. HA! You folks eat all the meat you want, but I prefer to be healthy !
  • You are, without a doubt, the voice of reason in the storms of diet controversy. Thank you for always providing thoughtful and well-researched analysis of these two viewpoints!
  • Great video, and I agree. My anecdote: At age 41 I had a heart attack. In the hospital, I was then also diagnosed with diabetes with an A1C of 7.2. My triglycerides were 13. My total cholesterol was 212.7mg/DL and my LDL was 243.6mg/dL. I resisted ALL the medications prescribed for me and went on a whole-foods plant-based diet with nearly zero oils. I cured my diabetes in weeks. My LDL cholesterol went down to 104.4mg/dL (a drop of nearly 140 points!!!). After those results, I continued to lose weight until I tapered off at a BMI of 21.3. I have kept all of that weight off for over 2.5 years now, without even trying. I love my body now. I look and feel great. My gout disappeared. My sleep apnea disappeared. My diabetes has never returned. My chronic heartburn disappeared. My average blood pressure is 115/75 despite having a high-stress job that does crank that up during periods of high stress. Often, I test at 110/70. My mood has been much more stable. I've been happy for the first time in a many years. I did great on all my stress tests. I remain on NO medications at all. I ran a marathon and my cardio level is very good without trying much. It's been an amazing journey. The reason some people on this diet can seem pushy at times is that they get passionate about spreading the news! Eventually, after 2 years of just this diet, and walking a lot, I started lifting weights. I don't feel sore after a workout, or the next day, or the day after that. It's pretty wild, because in the old days while eating meat I would be very sore after intense workouts. I have hit my maximum bicep curl weight, for example, and have had no trouble building this muscle mass, and never feel sore. ... Anyway, this video is great and I agree with the points made, but sometimes you have to go with what appears the most sensible on a balance of evidence. In my opinion, that's a diet primarily based on whole plant foods. Add a LITTLE animal protein? Maybe... but then you also have to consider things like the bacteria that raw chicken brings into your house, etc. I don't think you need meat or fish for any reason.... I choose to stick to a WFPB diet, but will keep tabs as science develops, always being wary of who FUNDED the studies as well...
  • I believe it’s the decrease in vinyl record sales that have caused the increase in diabetes.
  • @skippy6462
    Myself and my husband's h health improved following Dr. Greger's DAILY DOZEN. Best book on nutrition is How Not To Die.
  • @voicedbird
    I would be lost in so much nonsense if it weren't for this channel. Thanks so much for all your hard work!
  • @mayurim9839
    I think the best thing about this channel is that it never attacks the people and there's no emotion attached to any statement made from either party. Thank you for the video; found it super helpful! 🙂
  • @leeduli
    Dr. Greger's daily dozen has been instrumental in me staying healthy and getting the nutrients I need as a vegan. Thank you for fact checking him and keeping us all informed; I've always had the feeling he was motivated. Your videos are the best I've seen on youtube for fact-based and balanced nutrition information.
  • @RodKruz
    Dr. Greger "said there's one diet ever proven to reverse the progression of heart-disease", he didn't mention it was the only thing you have to do. He actually talks a lot about not smoking and exercising in his website.
  • @sandeepnij
    Regarding that chart showing red meat consumption going down when diabetes risk was going up, it's worth pointing out that cigarette consumption was also going down at the same time. Perhaps we should restart smoking to prevent diabetes? 😊
  • I'd like to see Dr. Greger on your show to hear his side of the story.
  • @robertusga
    Michael Greger helped me turn my horrible diet around to a healthier one. Gil Carvalho helped me see that when it comes to health claims, we should focus on outcome based data from quality studies in humans and not trying to bend / misrepresent those studies to fit a certain agenda. Thanks Gil!
  • @jhunt5578
    I appreciate you scrutinising Vegan doctors. I'm a Vegan myself, have been for 5 years. It's good to hear a balanced perspective.
  • Dr Gregor grandmother reversed her heart disease after she was sent home to die at the age of 65 and she died age 95 after changing her diet and going for long walks. There are many people getting better on a low fat high fiber diet, with exercise.
  • @C2C.
    Thanks again for your continued evidenced-based discussions. While I agree that Dr. Gregor could have done a better job in presenting his arguments, it's clear that Ivor Cummings was engaged in systematic factual misrepresentation and distortions to an egregious degree. This video would have been better presented as a review of the flaws in this type of sensational media "debate," as well as the types flaws and fallacies debaters will resort to. A better way to address Dr. Greger's positions would be to review a compilation of comments he's made in his videos. Here, most of the problematic claims were actually made by Cummings.
  • I am in diabetes prevention in a Native American community in the US, and I find your channel immensely helpful. Thank you!
