First seen Jun 27, 2026 · Last updated Aug 11, 2026 · Updated 2 times
Summary
This study tests whether eating only during a specific window each day (time-restricted feeding) can improve metabolic health in postmenopausal women who have metabolic syndrome or are prediabetic. Researchers will measure changes in insulin sensitivity, body weight, and blood fats. The goal is to find a simple lifestyle change to reduce disease risk without medication.
