This guys says a lot of things that go along with what Mark says, and like other people, he says stuff that doesn't agree with what Mark says. The one thing I am interested in is what he says about calories. He says that they don't matter because the way we figure out calories is by burning them which is way more simple than how our body processes food. If you want to watch the whole thing, it's about an hour long. What do you guys think? And Mark, I would love to hear what you have to say too.
