* Have used insulin therapy (outside of pregnancy) any time in the past 2 years, except for short-term treatment of acute conditions, and up to a maximum of 4 weeks; any insulin use within 3 months prior to the first study visit
* Have been treated with drugs that promote weight loss within 3 months of the first study visit
* Are receiving chronic (greater than 14 days) systemic glucocorticoid therapy or have received such therapy within the 4 weeks immediately prior to the first study visit
* Have had any of the following cardiovascular conditions within 2 months prior to the first study visit: acute myocardial infarction, New York Heart Association Class III or Class IV heart failure, or cerebrovascular accident
* Have a known clinically significant gastric emptying abnormality (such as, severe diabetic gastroparesis or gastric outlet obstruction) or have undergone gastric bypass (bariatric) surgery or restrictive bariatric surgery
* Have acute or chronic hepatitis, signs and symptoms of any other liver disease, or alanine transaminase level greater than or equal to 3 times the upper limit of normal
* Have a history of chronic pancreatitis or acute idiopathic pancreatitis or were diagnosed with any type of acute pancreatitis within the 3 month period prior to the first study visit
* Have a serum creatinine greater than or equal to 1.5 milligrams/deciliter (mg/dL) (male) or greater than or equal to 1.4 mg/dL (female), or a creatinine clearance less than 60 milliliters/minute (mL/minute)

4. An underlying disease known to have important effects on glucose metabolism
5. Active infections
6. Renal disease (serum creatinine ≥1.4 mg/dl for men; ≥1.3 mg/dl for women) or serum potassium abnormality (\<3.4 or \>5.5 mmol/l)
7. Anemia (hemoglobin \<11g/dl in women, \<12 g/dl in men) or known coagulopathy
8. Cardiovascular disease, including uncontrolled hypertension and symptomatic congestive heart failure. Participants must be able to safely tolerate administration of fluid/volume challenges during clamp studies.
9. Serum AST \>3 times upper limit of normal in local clinical lab

    1. unable or unwilling to give informed consent
    2. unable to adequately communicate with clinic staff

    5. likely to move away from participating clinic in next 2 years
    6. current (or anticipated) pregnancy and lactation.
    7. major psychiatric disorder that, in the opinion of clinic staff, would impede the conduct of the study
    8. weight loss \>5% in past three months for any reason except postpartum weight loss.
13. additional conditions may serve as criteria for exclusion at the discretion of the local site
D: Inclusion Criteria:
