Fasting and postprandial plasma pancreatic polypeptide (PP) levels in obesity

Twenty-three morbidly obese and 17 control subjects were studied with a breakfast meal. Neither fasting nor postprandial plasma pancreatic polypeptide (PP) levels differed significantly between the two groups, whereas postprandial serum insulin and blood glucose were significantly higher in the obese subjects. Our results do not support the suggestion that PP participates in the appetite regulation or the development of obesity.
