Key finding: One subgroup showed fast gastric emptying, stronger postprandial hunger, and lower plasma PYY and GLP-1, with reduced PYY gene expression in colonic mucosal samples and greater weight loss on tirzepatide at six months in a retrospective comparison.
A 2026 study of 483 adults with obesity profiled gut hormones including peptide YY and grouped participants by gastric emptying speed and GLP-1 levels after a meal.
