5 Diets That Naturally Stimulate GLP-1: The Injectable-Free Path to Sustainable Weight Loss

Another highly effective strategy is Intermittent Fasting (IF), which involves confining eating to a small, specific window of time each day. The periods of fasting—when the stomach is empty—are essential for modulating hormone levels. During these non-eating intervals, the body naturally increases the secretion of GLP-1. This ensures that when the eating window begins, the hormone is active, slowing digestion and enhancing the feeling of fullness to prepare the body for the next meal, ultimately aiding in calorie reduction.
