Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this study is to use advanced MRI scans to track changes in both muscle and fat in the body and heart over a 12-month period in individuals starting semaglutide. By doing so, we hope to gain a clearer understanding of how semaglutide affects muscle health and function. Our goal is to ensure the medication supports long-term well-being, particularly for people who may be at higher risk of muscle loss.

This study involves (3) in-person study visits. At each visit, participants will be asked to:

* Undergo magnetic resonance imaging (MRI) while resting and during exercise to take pictures of their heart, abdomen, and legs.
* Complete tests to assess balance, sit-to-stand, walking speed, and handgrip strength.
* Complete questionnaires (related to demographics, health information, physical activity, and nutrition).
* Have a blood sample collected.
* Have blood ketone levels assessed through two finger pricks.
* Complete three days of food records.
