BackgroundThe glycemic-independent actions of glucagon-like peptide 1 (GLP-1) in the prandial state in humans are largely unknown. Protein ingestion stimulates beta-cell secretion without changing plasma glucose concentration. We examined the contribution of endogenous GLP-1 to glucose metabolism and beta-cell response to protein ingestion under basal glucose concentrations, and whether these responses are affected by rerouted gut after gastric bypass (GB) or sleeve gastrectomy (SG). MethodsIns...
