When you eat a big protein meal (100g) after working out, a larger portion of the protein building blocks for your muscles comes directly from that meal (27%) compared to a smaller meal (9%).
Scientific Claim
The ingestion of protein after resistance exercise results in a greater contribution of exogenous-protein-derived amino acids to muscle protein synthesis with higher protein doses, with 27% of myofibrillar protein synthesis coming from dietary protein after 100g protein ingestion in healthy young men.
Original Statement
“We observed that exogenous-protein-derived amino acids contributed 9% and 27% to total amino acid incorporation following the ingestion of a meal-like amount of protein (25PRO) and the large amount of protein (100PRO), respectively (Figure 6H).”

Assessment Explanation
The study directly measured the contribution of dietary protein to muscle protein synthesis using isotope tracers. The quantitative data is presented with specific values and statistical significance.
