Eight-Hour Eating Window Helps Maintain Weight Loss for 12 Months

A 12-week randomized trial with 99 overweight adults on a Mediterranean diet found that an eight-hour eating window (16:8) helped maintain weight loss 12 months after the intervention, with both early (9:00–17:00) and late (13:00–21:00) fasting outperforming a longer usual eating window; early fasting also reduced fat mass, and about one in three participants continued intermittent fasting during follow-up, indicating feasibility of TRE for long-term obesity management.
