Verdict on whether eating more protein than the official recommended amount preserves muscle and supports healthy aging: Leaning for. Most adults, and especially those over 50, do better on more protein than the 0.8 g/kg RDA: about 1.2-2 g/kg a day, paired with resistance training. The worry that high protein shortens life rests on keeping IGF-1 and mTOR low; exercise steers IGF-1 toward muscle, and muscle loss is the bigger risk with age.
