Meta-Analysis
Pro
Morton RW et al. · 2018British Journal of Sports MedicineLarge meta-analysis of 49 studies (1863 participants) found that dietary protein supplementation significantly augmented resistance training-induced gains in muscle mass and strength. The analysis identified a breakpoint at 1.62 g/kg/day beyond which additional protein did not further contribute to resistance training-induced gains in fat-free mass.

Cermak NM et al. · 2012American Journal of Clinical NutritionMeta-analysis of 22 RCTs showed that protein supplementation during prolonged resistance-type exercise training augmented gains in fat-free mass (+0.69 kg, 95% CI 0.47-0.91) and 1-RM leg press strength compared to placebo. Effects were observed in both younger and older populations.

Bandegan A et al. · 2017Journal of NutritionIndicator amino acid oxidation studies estimated that the protein requirement for young male bodybuilders was approximately 1.7-2.2 g/kg/day during periods of intensive training. This exceeds the general population RDA by a substantial margin, supporting the claim that athletes engaged in resistance training benefit from higher protein intakes.
