When young, active people eat more protein after working out, their bodies don’t just steadily build more muscle — instead, the way their body handles protein changes in a more complicated, up-and-down way involving both making and breaking down protein.

Whole Body Net Protein Balance Plateaus in Response to Varying Protein Intakes During Post‐Exercise Recovery: Identification of a Maximal Anabolic Intake

Cross-Sectional Study

Human

The study found that eating more protein after exercise doesn’t keep improving muscle repair forever—there’s a limit, and it’s not just because the body makes more protein, but because of small changes in both making and breaking down protein.

Similar Assertions

After working out, your body builds muscle best when you eat protein and carbs in a certain mix — about 1 part protein to 3.2 parts carbs. Eating more carbs beyond that might not help you build more muscle.

If you're a healthy, active young person working out, eating more protein helps your muscles recover — but only up to a point. After about 1.6 grams of protein per kilo of body weight each day, your body can't use any extra to build more muscle.

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.

79%

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.

Eating more protein after working out leads to a better overall protein balance in your body - the more protein you eat, the more positive your protein balance becomes.
