The stomach empties more slowly after meals rich in fats and proteins compared to carbohydrate-rich meals. This is because the presence of these macronutrients in the duodenum stimulates the release of hormones, such as cholecystokinin (CCK), and activates the enterogastric reflex. These responses inhibit gastric motility and contraction, allowing more time for the complex digestion and absorption of fats and proteins in the small intestine. Carbohydrates, being simpler, are processed more quickly.
