however, when hypertrophy (as well as muscle mass maintenance), performance, and/or endurance are your goals, you need more protein, period.
even the vegan BBs need to supplement with a lot of powders/shakes in order to achieve the minimum requirements of a lifter; if you can stomach pea, rice, and wheat pro blends (pretty hardcore stuff by the way) everyday, then more power to you
and the claims of humans being 'natural plant eaters' is hooey perpetuated by PETA wackjobs
