exercise does not increase appetite

In plain terms: Does moderate exercise fail to reliably increase hunger in most people?

consensus score 0.57

Largely true — acute exercise doesn't reliably raise hunger or food intake and often briefly suppresses it, though a subset of people do compensate by eating more, so 'never' is too strong.

What the evidence shows

Acute exercise does not reliably raise hunger or food intake and often briefly suppresses it: pooled trials show suppressed acylated ghrelin, raised satiety hormones and a trivial effect on absolute energy intake, with no compensation for the energy spent. Longer training is less settled — an eight-week trial raised fasting GLP-1 and PYY alongside appetite changes.

Disagree, or know a study we missed?

We grade by evidence, not opinions. The way to weigh in is to point us to a study we haven't cited (check the evidence table above first), or to flag a problem with one we have. Every submission is reviewed; if it holds up, the grade updates and shows in Science Changes Its Mind.
