The Biology of Why Obese People Eat More: Disrupted Peptide Signaling in Obesity
Obesity involves disrupted appetite peptide signaling at multiple levels — reduced satiety responses (GLP-1, PYY), altered reward processing (endorphins), and ghrelin dysregulation — creating a biology that drives overeating.
Quick Facts
What This Study Found
Eating behavior in obesity reflects disrupted multi-level peptide signaling: blunted gut satiety peptides (GLP-1, PYY, CCK), altered opioid reward processing, ghrelin dysregulation, and impaired central neuropeptide circuits — biology driving behavioral excess.
