The greatest degree of satiety would be expected for the situation involving distension of the stomach by an inflatable bag, in combination with infusion of nutrients directly into the duodenum. This is because satiety depends not only on the amount of food in the stomach but also on the release of satiety hormones and neural signals that occur during the digestion of nutrients in the intestines. Infusing nutrients directly into the duodenum bypasses the stomach and triggers the release of these satiety signals, while the distension of the stomach by the inflatable bag mimics the physical sensation of fullness. This combination is likely to produce the strongest satiety response.
