Eating more protein after working out makes your whole body build more protein - the more protein you eat, the more protein your whole body builds.

Scientific Claim

The ingestion of protein after resistance exercise results in a greater increase in whole-body protein synthesis rates with higher protein doses in healthy young men.

Original Statement

“We observed a further increase in both whole-body protein synthesis and amino acid oxidation rates following the ingestion of 25 and 100 g protein, respectively (Figures 2G and 2H).”

From study:The anabolic response to protein ingestion during recovery from exercise has no upper limit in magnitude and duration in vivo in humans

Evidence Quality Assessment

Claim Status

appropriately stated

Study Design Support

Design supports claim

Appropriate Language Strength

definitive

Can make definitive causal claims

Assessment Explanation

The study directly measured whole-body protein synthesis rates using isotope tracers and found statistically significant dose-dependent increases. The causal language is appropriate for this study design.

Similar Assertions

Eating a big protein meal (100g) after working out makes your body make more plasma proteins than a smaller meal (25g) - about 14-20% more over 4-12 hours.

94%

Eating a big protein meal (100g) after working out makes your muscles keep building for longer than a smaller meal (25g), at least for 12 hours.

93%

Eating protein after working out only increases the building of connective tissue in muscles for about 4 hours - after that, the building rate goes back to normal.

91%

Eating protein after working out doesn't change how fast your muscles break down protein - it just helps build more muscle without affecting the breakdown process.

90%

Eating protein after working out doesn't make your body burn more protein as fuel than it needs for building muscle - most of the protein goes toward building muscle instead of being burned for energy.
