if you want to gain weight, all you need to do is intake more calories than you burn off. i'd say eat an extra 500 calories a day (if can be healthy foods if you want) na dhtat will put on weight in a healthy time span ( 1 - 2 pounds a week). all my sports med and nutrition classes go over this and say the same thing.

When my time comes, I want to be burried face down. That way, anyone that doesn't like me, can kiss my ass!
