Summary

This study looks at how eating and sleeping at mismatched times (like shift workers do) affects weight regulation. Researchers will track 42 adults with overweight or obesity, measuring energy use, body composition, and brain responses to food. The goal is to understand whether aligning meal and sleep times helps control weight, independent of how long you sleep.

What this could mean

What this could lead to: If successful, this study could provide clear guidance on how timing meals and sleep can help manage weight, especially for shift workers or people with jet lag.
What could go wrong: This is a small, early-stage observational study (42 participants) that measures effects over a short period. Results may not apply to everyone, and it does not test a treatment or intervention.
