LOLOL.
The dumb thing about bodybuilders is that they don`t realize there is Zero Evidence of effectiveness for increasing protein and that RDA Protein recommendations, based on the individuals body weight, is high, to cover a humans needs. The average requirement for protein is 0.6 grams per kilogram of body weight; the RDA is 0.8 grams which has statistically proven to meet 97.5%-99% of the population's needs.
Lemon, in Medicine and Science in Sports and Exercise (19:5, S179-S190,1986), states:
"Several types of evidence indicate that exercise causes substantial changes in protein metabolism. In fact, recent data suggests that the protein recommended dietary allowance might actually be 100% higher for individuals who exercise on a regular basis. Optimal intakes, although unknown, may be even higher, especially for individuals attempting to increase muscle mass and strength."
So if I understand that correctly, there is some evidence after all...
