Check out this site, I know this guy is the real deal. I've been reading the magazine Muscle Media for years and he won their transformation contest back in 97 or 98.
Basically you need to eat consistently. 5 to 6 meals a day, high protein and up your caloric intake to 3000+ calories a day. It's hard, when I was eating 6 meals a day I was always full, but I noticed changes quick. If you want it bad enough you can do it, the info is out there, you just need to apply it. Good luck.
