Early Time-Restricted Feeding

Meaning

Early Time-Restricted Feeding (eTRF) is a specific dietary intervention where all caloric intake is intentionally confined to an early-day feeding window, typically lasting 6 to 10 hours and concluding well before the evening. This strategy leverages the body’s naturally higher insulin sensitivity and more efficient metabolic capacity during the morning and early afternoon hours. The practice is designed to align nutrient intake with the optimal timing of peripheral organ clocks, promoting metabolic flexibility and improving glucose tolerance. eTRF is often utilized clinically to enhance cardiometabolic health and support healthy weight management.
