As someone who works out daily; the point at which I was in the best shape of my life was when I was consuming large amounts of fats. Peanut butter, olive oil, etc. I also find it really really hard to believe that protein would cause obesity; I've heard the exact opposite.

People have been posting similar studies of Indian and Asian countries, basing their recommendations for everyone off that subset of the population, and then completely discount that of traditional European, African, and American diets.
