Gastric emptying is the process by which the stomach delivers chyme into the duodenum at a controlled rate, coordinated by gastric motility, pyloric tone, and duodenal feedback so that nutrient delivery matches the small intestine’s digestive and absorptive capacity. In nutritional psychology, gastric emptying rate is a key determinant of satiety, postprandial glucose dynamics, appetite-hormone release, and vagal gut-brain signaling, and it is modulated by stress, emotion, and cognitive-sensory factors as well as by meal composition and pharmacologic agents such as GLP-1 receptor agonists.
