Eating Within Set Hours Versus Standard Calorie Counting for Weight Loss

This research trial is testing whether limiting the *hours* you eat (called time-restricted feeding) works better than simply counting calories for weight loss. Women in the study will be randomly assigned to one of three groups: some will follow a calorie-restricted eating plan with no time limits, while others will restrict both their calories and the hours they eat—choosing either a morning schedule (8 a.m. to 4 p.m.) or an evening schedule (12 p.m. to 8 p.m.). Researchers want to understand if eating within a specific time window makes weight loss easier or more effective than traditional calorie counting alone.

Many people struggle with weight loss using standard calorie-counting diets alone. This trial exists to explore whether giving your body a daily eating and fasting schedule—a newer approach that's become popular—offers an added benefit over traditional methods, and to see if timing matters for women managing overweight or obesity.
