What this Trial Is About
Researchers are studying the effects of Time-Restricted Eating (TRE) on the 24-hour Activity Cycle (24-HAC) in college-aged women. TRE limits eating to a daily 8-hour window without changing diet quality and has shown benefits such as weight and fat loss, better glucose control, and reduced inflammation. However, its impact on physical activity, sedentary behavior, and sleep—the key parts of the 24-HAC—has not been well studied, especially in healthy young adults like college students, whose schedules and circadian rhythms can make TRE adherence challenging.
