causal
neutral effect

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.

Scientific Claim

The ingestion of protein after resistance exercise does not significantly impact muscle protein breakdown rates in healthy young men.

Source Excerpt

“Protein ingestion has a negligible impact on whole-body protein breakdown rates or amino acid oxidation rates.”

Evidence from Studies

Supporting Studies

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

Evidence Assessment
Supported

The study measured whole-body protein breakdown rates using isotope tracers and found no significant differences between protein ingestion conditions. The data indicates protein ingestion primarily affects synthesis rates rather than breakdown rates.

Similar Assertions

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.

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.

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.

90% similar

Eating protein after working out doesn't change most amino acid levels in your muscles, but it does increase the levels of branched-chain amino acids like leucine, especially with bigger protein meals.
