Hormonal

Colonic SCFA mixtures increase plasma Peptide YY (PYY) concentrations, a satiety-stimulating hormone, in both fasting and postprandial states.

Eating fiber-rich foods stimulates the release of Peptide YY (PYY), a hormone that signals fullness to your brain. To manage appetite, ensure your diet includes sufficient fermentable fibers (found in vegetables, fruits, and whole grains) to support natural PYY production.
