Beyond about 1.6 g protein/kd/d it doesn't matter what protein you eat to support muscle mass gains https://t.co/Rd17RadTIN and protein is

what it claims

Beyond 1.6 g of protein per kilogram of body weight per day, additional amounts matter little for muscle mass gain; resistance training remains the absolute priority, well ahead of protein intake or supplements.

Stuart Phillips, a recognized expert in muscle physiology, relies here on solid data. A major meta-analysis published by Morton et al. (2018) in the British Journal of Sports Medicine effectively confirms that the benefit of protein intake on hypertrophy plateaus at around 1.6 g/kg/day. The idea that training is the primary driver of change is also validated by scientific literature: mechanical stimulus is essential to signal muscles to grow. The statement is therefore very accurate and aligned with the current consensus. There is no exaggeration here; the creator simply puts protein back in its rightful place, that is, as a supportive tool rather than a miracle factor. It is a rational perspective that helps prioritize efforts rather than focusing on minor nutritional details.

What the graded evidence says

Evidence
B+
Effect
muscle hypertrophy and 1RM strength, low-load vs high-load resistance training — hypertrophy similar between low and high loads when sets taken to/near failure; 1RM strength significantly favors heavier loads
Measured on
healthy adults, trained and untrained

What’s uncertain

Light loads match heavy loads for size only when sets are taken close to failure; for pure maximal strength, heavier loads have the edge, and body-weight training eventually needs harder variations to keep progressing.
