He's not going to listen to or learn anything from any of you. He will be back to eating deep fried snickers bars ala mode for a midnight snack within a week. The point of this thread is not, "help me plan and stick to a diet". Just like the point of "I am desperate and alone, and turned down by annoying, fat, hairy chicks" is not him asking you for dating advice. The sooner you realize that, the less tine you'll waste trying to "help" him.
