Time-Restricted eating: a simple fix for better sleep and more movement?
NCT ID NCT07520786
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether limiting food intake to an 8-hour window each day can improve sleep, physical activity, and reduce sitting time in college-aged women. Thirty-six female students at the University of Georgia will either follow this eating pattern or receive basic nutrition advice for three weeks. Their activity and sleep will be tracked with a wrist monitor to see if time-restricted eating makes a difference.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Time-restricted eating (8-hour daily eating window)
- What this could lead to
- If successful, this could show that time-restricted eating is a feasible way to improve daily activity patterns and sleep in young women.
- What could go wrong
- This is a small, early-stage study with only 36 participants, all college women, so results may not apply to other groups. Adherence to the eating window may be low.

Inclusion Criteria: * Female undergraduate and graduate students * Enrolled full-time at University of Georgia * Aged 18-26 years Exclusion Criteria: * having one of the following chronic diseases that maybe impacted by the diet changes: type 1 and 2 diabetes mellitus, cancer, cardiovascular diseases, hypertension, thyroid dysfunction, hepatic/renal impairment, inflammatory bowel disease and other gastrointestinal diseases, * report use of nicotine, thyroid medications, antidepressants, or anti-anxiety medications, melatonin * having clinically diagnosed sleep disorders * alcohol intake exceeds two drinks per day * clinically diagnosed or undiagnosed eating disorders * division-1 student athletes * pregnant or lactating or plan on getting pregnant within 6 months * report major ambulatory disorders, * recently (within the past two weeks) engaged in caloric restriction, timing-based dietary changes, weight loss regimens, or adhered to specialized diets such as ketogenic or paleo diets, * required to take medication with food, as these factors may interfere with sleep and physical activity outcomes or pose risks to participant health during restricted eating protocols. Students whose habitual eating time windows are \<10 hours will also not be eligible.
