Fatty meals delay gastric emptying because fatty acids entering the duodenum stimulate release of cholecystokinin (CCK) from intestinal I cells. CCK inhibits gastric motility, reduces the pyloric pump, and increases pyloric sphincter contraction. This slows delivery of chyme into the duodenum, allowing sufficient time for fat digestion and absorption.
