Peptide YY and Satiety
PYY is a gut hormone that curbs appetite after protein- and fiber-rich meals. Volume and whole foods support stronger signaling than processed snacks.
Peptide YY (PYY) is released from the gut after eating—especially meals with protein and fiber—reducing appetite for hours. Low PYY responses may contribute to hunger soon after processed, low-volume meals.
Volume eating with vegetables and adequate protein supports stronger PYY signaling without magic supplements.
