Resistance training mitigates the diminishing returns of high protein intake (>1.3 g/kg/day) on lean body mass gains.

If you are eating more than 1.3 grams of protein per kilogram of body weight, you should be doing resistance training. Without training, your body becomes less efficient at turning that extra protein into muscle. Training keeps the 'bang for your buck' high even when you eat a lot of protein.
