Summary

This study tested whether restricting eating to a 10-hour daily window improves blood sugar, appetite, and body clock function in night shift workers. Twenty-two healthcare workers followed the eating schedule for 8 weeks, then their usual diet for another 8 weeks. The goal was to see if time-restricted eating helps regulate glucose and reduce inflammation.
