# Less protein may support longevity, major review finds

> A review of more than 350 studies suggests that restricting protein may improve metabolic health and influence biological ageing, with FGF21 and the amino acids methionine, isoleucine and valine highlighted as possible mechanisms. Some human trials found improvements in weight, body fat and fasting blood sugar, but the evidence does not establish that protein restriction extends human lifespan.

## Why it matters

The findings could influence dietary guidance and demand for high-protein foods or supplements, but they do not provide a clear near-term animal-feed demand signal. The benefits and risks of lower protein intake in people remain uncertain.
