I don't buy into any of that hogwash. They put that out to sell tickets. It's just a classic horror movie, with the Greek drama formula of good versus evil, and lots of fear.
I eat 230 grams of protein daily, 308 grams of carbohydrates, maybe 70 grams of fat. I can have one cheat meal a week but it can't be that I eat until I'm stuffed; I eat until I'm satisfied.
