Actions of glucagon-like peptide 1 (26)

Brain	Induces feeling of satiety
	Reduces food intake
Gastro intestinal tract	Delays gastric emptying
	Delays food absorption
Pancreas	Stimulates glucose-dependent insulin secretion
	Suppresses glucagon secretion
	Increases beta-cell sensitivity
	Increases beta-cell mass (animal studies only)
Liver	Decreases hepatic glucose output because of reduced glucagon secretion
Fat/muscle	Stimulates glucose uptake
Heart	Increases myocardial protection
	Improves endothelial function
	Decreases blood pressure
	Improves left ventricular function
