Summary

This study looks at whether eating all meals within a 6-hour window (early time-restricted eating) changes appetite and hunger-related hormones compared to eating over 12 hours. Twelve healthy men without obesity will try both eating patterns on separate days. Researchers will measure hormone levels and how much they eat afterward to see if meal timing affects appetite.

What this could mean

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

Active substance: early Time-Restricted Eating (eTRE)
What this could lead to: If successful, this could provide insights into how meal timing affects appetite and energy balance, potentially informing future dietary guidelines.
What could go wrong: This is a very small, early-stage study in healthy men only, so results may not apply to women or people with health conditions. The intervention lasts just one day, so long-term effects are unknown.
