Can exercise curb appetite better than diet alone in teens?
NCT ID NCT04734639
First seen Aug 07, 2026 · Last updated Aug 07, 2026
Summary
This trial investigates how different ways of creating an energy deficit affect appetite and food intake in adolescents with obesity. Participants will experience three conditions: exercise combined with dietary restriction, dietary restriction alone, and a rest control. Researchers will measure hunger feelings, food reward, and how much they eat at a buffet meal to see if adding exercise changes appetite responses.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Behavioral interventions: exercise plus dietary restriction versus dietary restriction alone, compared with a rest control condition
- What this could lead to
- If successful, this could help design more effective weight-management programs for adolescents with obesity by understanding how different energy-deficit strategies affect appetite.
- What could go wrong
- This is a small, early-stage study with only 17 participants, so results may not apply broadly. Appetite responses can vary widely among individuals, and the findings may not lead to a definitive conclusion.
