Obese People Release Less PYY After Meals — Explaining Their Reduced Satiety

Obese subjects had attenuated PYY3-36 release after meals compared to lean controls, with the blunted PYY associated with reduced subjective satiety — explaining why obese individuals feel less full after eating.

What This Study Found

Obese subjects demonstrated attenuated postprandial PYY3-36 release compared to lean controls, with reduced PYY correlating with diminished subjective satiety — PYY deficiency contributes to impaired meal-related fullness signaling in obesity.
