How much protein do we actually need? It varies from person to person. In my patients I typically set 1.6 g/kg/day as the minimum, which is twice the RDA. The ideal amount can vary from person to person, but the data suggest that for active people with normal kidney function, one gram per pound of body weight per day (or 2.2 g/kg/day) is a good place to start—nearly triple the minimal recommendation.
