Project X - Lose Weight!

I am 6 ft 4 in and go from 285-295 lbs depending on my eating habits, when I am in shape I weigh 260lbs.... when I see that a large frame guy at my height you should weigh no more than 220 lbs I just shake my head. In my defense I am one of the types that weigh more than what it looks. I have a friend who does weigh around 215 and is about 6ft 3in and we look about the same weight (when I weigh 260) I havnt been to the gym in about a yr
