yes they do. heard a pro at my gym talking that he ate 22 flank steaks in 2 days. 9 meals one day and
8 the next. i see him at the grocery store too, with cart loaded.
Watch a 320lb guy eat for a few days. It'll blow your mind.
Thing is taht guy I know holds back, he'd eat even MORE if he could afford it!
Ive watched him Devour a pile of steaks about 6" high, w/ Potatoes, broccoli, bread & butter, pie, milk...
Hes not a BBer, but if he had higher lean mass - He have to eat even more!
