maybe it worked for him but not others..besides hes an athlete...im pretty most of us guys dont have all the time athlete does...he has all the time to burn off that ice cream and pbj...you dont want to eat those...atleast not every night....its good to eat it once in awhile for like say a reward for your hard diet....besides when your in your teens your hormones are still developing and you still have alot of testosterone...guys that are older lack that stuff thats why they made testosterone boosters...well anyways when in your teens you always have energy to burn...its a part of growing up...now if you really want to pack on some meat try eating a good protein meal say...steak and whole chicken....you dont want to eat something with bad calories but good ones..heheh...
