About this trial
More than 40% of young adults with type 1 diabetes (T1D) also have overweight or obesity. Each of these diagnoses increase the risk of adverse cardiovascular events. Investigators aim to obtain reference data for individuals with T1D who do not have overweight obesity, to understand how close GLP-1 analogue obesity treatment in those with overweight/obesity brings physiologic markers of cardiometabolic risk to those with BMI in the normal range. Specifically, investigators will describe how drivers of gluconeogenesis and lipemia (specifically measured as visceral fat ratio, insulin resistance, and postprandial lipemia,) that contribute to cardiometabolic risk in T1D change over time.
