Summary

This study will enroll 20 adults with severe obesity who are scheduled for weight-loss surgery. Researchers want to see if advanced tools like MRI and 3D body scans give a clearer picture of health changes than just measuring weight or waist size. Participants will be followed for up to one year after surgery to track changes in muscle, fat, and strength.
