How do fats affect gastric emptying?

Fats play a significant role in the process of gastric emptying, primarily by slowing it down. When fats are consumed, they stimulate the release of certain hormones, including cholecystokinin (CCK), which helps to slow gastric motility. This slowdown allows for a more gradual digestion and absorption process, as fats take longer to be broken down compared to carbohydrates and proteins. Additionally, the presence of fats in the stomach contributes to a feeling of fullness, which is linked to the slow release of the stomach contents into the small intestine.

This characteristic is important for regulating food intake and maintaining energy balance. It also enhances nutrient absorption and may affect overall digestion efficiency. Overall, understanding the influence of fats on gastric emptying is crucial for nutritional and dietary planning.
