I just read through some of his blog posts, seems pretty down on Ornish and how he manipulated his study cohort to get more favorable results.
Also very much pro high fat diet. Says don't worry about your cholesterol numbers except for LDL particle size, eat lots of coconut oil.
Personally I think he is more right than wrong, but he does seem to against a lot of what you preach here.
I agree that Hyman is way more fat friendly and much less worried about cholesterol than Peak is. Yet, there is lots of agreement that the best anti-aging diet is largely vegetarian. Lots of agreement that blood sugar is a very important risk factor. I would guess that Hyman would fully endorse at least 90% of what Peak writes about here.
Hyman is big into functional medicine. So his angle is that he is looking for what works. So sure he is selling books and stuff. I personally don't really begrudge anyone from making money. I think he uses his reasearch to further his role as director of Functional Med at the Cleveland Clinic.
I also admired his work on the fat summit. He brought in well known experts, who often held very different viewpoints and gave them all a pretty fair hearing. So he is not afraid to have sticks and stones thrown at his own ideas. It was a very intellectually honest move to have other viewpoints come on his show.
