Protein Across the Day: Does Distribution Matter?

Some research suggests spreading protein across meals supports muscle maintenance. The evidence is mixed.

Many people eat most of their daily protein at dinner. A line of research asks whether spreading it more evenly helps muscle maintenance.

Short-term laboratory studies show muscle protein synthesis responds to individual meals, which led to the even-distribution hypothesis.

Longer trials measuring actual muscle mass or strength have produced mixed findings, and total daily protein appears to matter more.

For most adults, meeting general protein recommendations through a varied diet is the more evidence-backed priority.
