(BMI values should be calculated to one decimal point precision and then assessed in terms of the required range.) * History of at least one self-reported unsuccessful dietary effort to lose body weight. * Group 1: Have a diagnosis of T2DM, with HbA1c \< 10% (86 mmol/mol) (measured at central lab during screening) and are on stable treatment for T2DM for at least 90 days prior to screening. * Group 2: No diagnosis or signs/symptoms of T2DM and HbA1c \< 6.5% (48 mmol/mol), measured at the central lab during screening. Exclusion Criteria: * T1DM, or a history of ketoacidosis, or hyperosmolar state/coma requiring hospitalization at any time prior to screening. * Have had 1 or more episode(s) of severe hypoglycemia in the 6 months prior to screening (Level 3 ADA 2025) defined as a severe event characterized by altered mental and/or physical status requiring assistance for treatment of hypoglycemia irrespective of glucose level, or has a history of hypoglycemia unawareness or poor recognition of hypoglycemic symptoms. Any participant that the investigator feels will not be able to communicate an understanding of hypoglycemic symptoms and the appropriate treatment of hypoglycemia should also be excluded. * History of stroke with residual neurological deficit within 2 years or transient ischemic attack within 6 months prior to Day 1. * History of acute coronary syndrome (ACS) including unstable angina, acute myocardial infarction (both ST segment elevation and non-ST segment elevation) within 6 months prior to Day 1. * Diagnosis of congestive heart failure (CHF) or clinical evidence suggesting CHF including history of orthopnea, exertional dyspnea, pedal edema, pulmonary rales, hepatosplenomegaly or cardiomegaly at the discretion of the Principal Investigator.
