Description

Shulin Zhang and co-authors lay out a trial protocol on appetite in older adults in this 2026 paper. Branched-chain amino acids are building blocks found in protein foods and supplements. Mouse work suggested they can drive overeating, depending on which other amino acids come along. No human trial had tested that idea in older people.

The trial enrolled 110 adults aged sixty-five to eighty for four weeks. Groups received no supplement, the amino acids alone, or mixes with tryptophan or methionine. Appetite reports, food intake, body measures, and blood markers are tracked. One hundred participants finished, and results are expected in 2027. The protocol shows how mouse findings get a careful human test.
