First seen Jun 27, 2026 ยท Last updated Jun 27, 2026

Summary

This study looked at whether eating only during a 9-hour window each day (time-restricted eating) affects bone health, weight, and gut bacteria in overweight or obese older women. 49 postmenopausal women were randomly assigned to either eat within a 9-hour window or a 12-hour window, while also reducing calories. The goal was to see if the timing of meals makes a difference beyond just cutting calories. No treatment or medication was tested.
