How regular exercise improves the body’s ability to regulate eating.
What the evidence says
- Acute exercise suppresses appetite without triggering compensatory eating[1]
- Chronic exercise may improve appetite regulation systems toward better satiety[1]
- Appetite responses to exercise vary dramatically between individuals[2]
- Individual variation is reproducible, not random noise — some are “compensators,” others aren’t[2]
- 12 weeks of aerobic exercise improves perceived fullness in overweight men[3]
- Aerobic training increases satiety; resistance training does not produce the same effect[3]
- Neither adiposity nor sex predicts who will compensate for exercise[1]
- Habitual exercisers may have better-calibrated appetite systems[1]
- Mean energy compensation averages ~18% of exercise calories, but with massive individual variation[4]
- Compensation increases over time: short-term low, long-term (~80 weeks) approaches 84%[4]
- Exercise improves leptin sensitivity in the brain independent of fat mass changes[5]
- This leptin effect cannot be replicated by calorie restriction alone[5]
- A 15-minute brisk walk significantly reduces sugary snack cravings in overweight individuals[6]
- Exercise attenuates craving responses to both stress induction and food-cue exposure[6]
- Exercise-induced improvements in affect (pleasure and activation) may mediate the craving reduction[6]
