One bike ride, big appetite shift? exercise may rewire food cravings in teens
NCT ID NCT06017440
First seen Aug 05, 2026 · Last updated Aug 06, 2026 · Updated 1 time
Summary
This study looks at whether a single 30-minute cycling session can alter how adolescents with obesity experience hunger and food reward after a fixed meal. Researchers will measure appetite feelings, food preferences, and how much they eat at a later dinner. The goal is to understand the connection between exercise and eating behavior in this age group.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- A single session of cycling exercise
- What this could lead to
- If exercise reliably changes how teens with obesity perceive hunger and food reward, it could inform simple, non-drug strategies to help manage appetite and weight.
- What could go wrong
- This is a small, early-stage study with only 16 participants, so results may not apply broadly. The effect of exercise on appetite can vary widely between individuals.
