Summary

This study tests whether limiting food intake to an 8-hour window each day (between 10am and 6pm) for 2 months helps children and teens with obesity lose weight. Researchers will also check if any benefits last and explore how the gut microbiome and body clock might play a role. The study involves 67 participants and compares the time-restricted eating plan to standard lifestyle advice.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Time-restricted feeding (eating only between 10am and 6pm, 6 days a week)
What this could lead to: If it works, this could offer a simple, drug-free way for children with obesity to lose weight and improve their health.
What could go wrong: This is a small, early-stage study with only 67 participants. The results may not apply to all children, and the 2-month program may be hard to stick with long-term.
