Dude i have a friend who is a fairly ripped 160lbs and he needs 4000kcal to bulk even a little. You cant make assumptions like that based on peoples weight alone. From what i've seen Overclocka is a very lean/skinny type and could well need huge caloric intake to make any headway, hopefully he has sense enough to back off if he starts gaining fat. On the plus side naturally skinny guys will drop weight like nothing if needed so fat gain is less of a worry
160lbs and needs 4000kcal to bulk even a little? Either he's not ACTUALLY taking in 4000kcal or he's 12 and spends all day running around mate.
How many lbs is he putting on a week @ "4000kcal"?
I know a lot of people who claim to be taking in this and that, but if you actually speant a day with them or worked out their diet they are normally way off.
