How much protein is needed for muscle gain?

Meta-analyses (Morton et al. 2018, Stokes et al. 2018) suggest 1.6 g/kg/day maximizes muscle protein synthesis for most people. Going up to 2.2 g/kg is safe and may help in caloric deficits.

Does protein need to be distributed throughout the day?

Yes. Studies show spreading protein across 3-5 meals of 20-40 g maximizes MPS stimulation better than two large meals. Each meal should contain enough leucine (2-3 g) to trigger MPS.

Does more protein than 2.2 g/kg help?

Evidence beyond 2.2 g/kg shows minimal additional muscle gain benefits for natural athletes. However, higher intakes are harmless for healthy individuals and help satiety during fat loss phases.
