Fat in the duodenum is the most potent stimulus for inhibition of gastric motility. This is because fat takes longer to digest and absorb, which means that it needs to stay in the small intestine for a longer period of time. In order to allow for proper digestion and absorption of fat, gastric motility needs to be slowed down. The other factors listed (acid in the duodenum, acid in the stomach, distention of the stomach) can also inhibit gastric motility to some extent, but fat in the duodenum is the most potent stimulant.
