Exercise vs. diet: which tames teen appetite?
NCT ID NCT04739189
First seen Aug 05, 2026 · Last updated Aug 06, 2026 · Updated 1 time
Summary
This trial compares how burning calories through exercise versus cutting calories through diet affects appetite and food intake in adolescents with obesity. Participants (aged 12-16) will undergo both conditions—an exercise session and a dietary restriction—and their hunger, food reward, and actual food consumption at a buffet meal will be measured. The goal is to understand whether exercise or dieting is more effective at regulating appetite, which could inform better weight-management approaches for teens.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Exercise-induced energy deficit versus dietary restriction
- What this could lead to
- If exercise proves better at controlling appetite than diet alone, it could inform more effective weight-management strategies for teens with obesity.
- What could go wrong
- This is a small, early-stage study (20 participants) that measures short-term appetite responses, not long-term weight loss. Results may not apply to all adolescents.
