Study of Patients Being Treated With Anti-obesity Medication

The goal of this observational study is to learn about the real-world effects of selected obesity medications in adults undergoing medical weight management. The main outcomes of interest are changes in body composition, routine clinical markers, muscular performance, and nutritional intake over the course of treatment. Additionally, the influence of lifestyle factors on changes in these outcome variables will be examined. Participants beginning treatment with selected obesity medications will undergo periodic body composition and muscular performance testing, as well as complete online surveys about their nutritional intake and physical activity and exercise participation. Additionally, routinely collected clinical information will be evaluated.
