NCT ID NCT07385716
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether time-restricted eating (eating only during certain hours) combined with a Mediterranean diet could help women with polycystic ovary syndrome (PCOS). Fifty-five women with PCOS and a BMI between 25-35 took part. The goal was to see if these diet changes improved their quality of life and body composition.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Mediterranean diet and time-restricted feeding
- What this could lead to
- If effective, this dietary approach could offer a simple, drug-free way to improve quality of life and body composition for women with PCOS.
- What could go wrong
- This is a small, completed study with no phase designation, so results may not be generalizable. Dietary interventions are hard to standardize and long-term adherence is uncertain.
