Aerated drinks such as foams have been shown to increase satiety, but intragastric mechanisms have not been explored. This study investigates the intragastric behavior of two foamed beverages with different stabilities compared to a non-aerated liquid control. Total gastric volumes and foam volumes were measured using MRI and correlated to behavioral scores, demonstrating mechanism of hunger suppression.
