Harvard Professor: “I Tried Every Diet. This Is By Far The Worst.” - Daniel Lieberman - #1137

0:00You've spent years researching every major diet and trying many of them yourself.

0:05I want to go through and review all of those.

0:07But first off, what was that journey like?

0:11Well, it was fun.

0:12I mean, I've been working for quite a few years on a book about the evolution of diet.

0:17And I thought rather than just simply studying them, which was the majority of the book, I thought I should try them as well.

0:24So kind of, you know, on and off as I was working on the book, my wife, who joined me for many of these diets, kept trying some of these, you know, diets, some of them, some of them better, some of them worse, but just kind of give a little, first of all, some participant observations.

0:37So I got a sense of what these diets are like, but also to kind of add context and experience them for myself.

0:44What did you start that journey believing about food that you no longer agree with?

0:51Gosh, I changed my opinions about so many things.

0:55I mean, the reason I started this book and this journey, as you say, is that I'm actually, my research is mostly on physical activity.
