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.
