A delayed-morning, earlier-evening time-restricted feeding (TRF) protocol (10:00–18:00 h) improves nocturnal glycemic control in men with overweight/obesity compared to extended feeding (07:00–22:00 h), while maintaining positive subjective adherence.

For men with overweight or obesity, shifting your eating window to start at 10:00 AM and end by 6:00 PM can significantly improve blood sugar levels during sleep compared to eating from 7:00 AM to 10:00 PM. This approach is metabolically effective and more socially sustainable than extreme early-fasting protocols, provided you maintain your total calorie and macronutrient intake.

Why this rating

Small sample size (n=11), short duration (5 days), and crossover design reduce generalizability, though the controlled lab setting minimizes confounding.
