To be a pro, eat a high-protein sports nutrition diet! The RDA for protein is .8 gram per kilogram of body weight (.36 g per pound). This is for sedentary people. Active people require more protein in their sports nutrition regimen.
Endurance athletes need 1.2-1.4 g/kg (.55-.64/lb). Strength athletes need 1.4-1.8 g/kg (.64-.81/lb). You can safely eat 2 g/kg (1 g/lb), but more than that is unlikely to be absorbed and utilized, though this varies with the individual.
