the whole feeling fuller longer and counter productivity is a good point my friend..
yet if you wanna grow, u gotta leave a coupla things behind..
1. your ego
2. your taste buds for the most part
3. your "feelings" of hunger or fullness
you follow a routine... u eat ever 2 1/2 hours..
you stuff your face untill u cant stuff your face anymore to the limitations of what your nutritional needs will be in that certain case.. then you stuff your face some more..
you get used to the feeling of full... to the point that you feel uncomfortable that you dont feel full..
EAT!!! GROW!!
it's about changing old habits... it's about the 150lb guy starting to eat like a 200lbs guy who's lean and ripped (just a point being made guys, dont take it literally..)
ask any larger guy what it takes to get big... he'll say the same thing.. go home and stuff your face... just stuff it with the right ingredients...
