Group description: Exenatide 10 micrograms injected subcutaneously twice daily for 6 months

Exenatide: Type 2 diabetic subjects will be randomized to receive either Exenatide 10 micrograms twice daily injected subcutaneously or glipizide 5 mg twice daily orally for 6 months. All subjects will receive baseline measurements of fasting plasma glucose, free fatty acids, plasma adipocytokines, plasma lipids, and glycosylated hemoglobin (HbA1c) as well as measurement of liver and myocardial fat content and left ventricular function with magnetic resonance imaging/spectroscopy. All subjects will also undergo measurements of monocyte inflammatory proteins at baseline. All subjects will undergo repeat measurements of fasting plasma glucose, Free Fatty Acids, adipocytokines, HbA1c, monocyte inflammation, as well as hepatic/myocardial fat content determination and left ventricular function at the end of the 6 months.
