The Claim

In healthy older adults, an even distribution of daily protein intake has no significant effect on muscle protein fractional synthesis rate (FSR) when compared to a skewed distribution of daily protein intake, despite differences in whole-body protein net-balance.

Source: Even or skewed dietary protein distribution is reflected in the whole-body protein net-balance in healthy older adults: A randomized controlled trial.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect
1 study reviewed
In plain English

In healthy older adults, spreading protein intake evenly throughout the day does not change the rate at which muscle proteins are synthesized compared to consuming most protein in one meal, even though overall protein balance differs between the two patterns.

See the scientific wording

In healthy older adults, an even distribution of daily protein intake does not significantly alter muscle protein fractional synthesis rate (FSR) compared to a skewed distribution, despite differences in whole-body protein net-balance.

Why this might work

When protein is spread evenly across meals, amino acids stay at steady levels in the blood, which tells the body to slow down the breakdown of existing proteins. This keeps more protein in the body overall, but it does not make muscles build new protein any faster. The muscles respond the same way whether protein is spread out or concentrated in one meal.

  1. Study: Even or skewed dietary protein distribution is reflected in the whole-body protein net-balance in healthy older adults: A randomized controlled trial.

    Evenly spreading protein across meals doesn’t make older adults’ muscles build protein faster, even though it helps their bodies hold onto more protein overall.
