I really like that guy and that video, he seems nice and like he is interested in the truth. My only question is, if insulin makes you fat and carbs control insulin levels, then why can some people eat carbs and not get fat? I personally can attest to being able to eat lots of carbs and not get fat, and I'm sure we all know someone in our lives that eats pasta and cereals and rice etc. and is skinny.
So there must be more to it, but that is an interesting video. Obviously amount of food does not dictate weight, something we were talking about in another thread. I eat way more than some heavier people I know.
