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.
