exercise does not reliably increase appetite
In plain terms: Does moderate exercise fail to reliably increase hunger in most people?

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.

| Murano S et al 2026 · study_type: observational | observational | supports | low | Cross-sectional study of 35 female university athletes: 74.3% reported post-exercise appetite LOSS (not increase), unrelated to sport type; poor sleep quality was associated with higher odds of appetite loss (OR=11.6). |
| França E et al 2026 · study_type: RCT | RCT | supports | moderate | Crossover RCT in 12 sedentary overweight men: sprint exercise (with or without leucine) reduced subjective appetite and food intake versus no-exercise sedentary conditions; leucine alone lowered perceived appetite but its effect on food int |

| Salton J et al 2026 · study_type: observational | observational | contradicts | moderate | UK population survey (n=1054 regular exercisers): 24% reported eating more on exercise days (mainly after exercise, 17%), associated with 'food as reward' beliefs, internal motivation, strength training, and disinhibition traits. |
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.
Opens a short form. You'll sign in with Google so submissions are tied to a real account — we don't display your identity, and we only accept a link we can verify (PubMed, DOI, ClinicalTrials.gov).
