I saw a couple of videos' through the UCSF web portal by this guy (Lustig) a few years ago. I can summarize what he said about various diets. The Paleo and Atkins diets work not because what they include but by what they exclude; processed carbs, sugar, and booze.
Another comment. Dr Lustig is a pediatric endocrinologist. If you start looking though the literature. Doctors, nutritionists, etc are all doing research to prove low fat diets work. And high fat diets are bad. And it's all about will power. The pediatric endocrinologists started working the processed carbs, sugar (fructose) are bad angle about ten to fifteen years ago. Probably about five years ago they became absolutely convinced this is correct.
