About this study
This observational study aims to collect detailed metabolic and physiologic data from adults with insulin-dependent type 2 diabetes mellitus following consumption of a mixed meal tolerance test. Participants will undergo frequent blood sampling over a 4-hour period after consuming a standardized liquid mixed meal to measure glucose, insulin, glucagon, C-peptide, and triglyceride responses. Participants will also use continuous glucose monitoring and wearable physical activity tracking devices during free-living conditions. The purpose of this study is to develop mathematical models and digital representations ("digital twins") of people with type 2 diabetes mellitus. These models may help researchers better understand metabolic responses to meals, physical activity, and diabetes treatments, and may support future development of personalized diabetes technologies and therapies.

- ✓ Able to provide informed consent
- ✓ Able to comply with and perform the procedures requested by the protocol (including dietary restrictions, consumption of study foods, records of food diary, sample collection procedures, and study visit schedule)
