First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether a personalized diet program and exercise, alone or together, can help older adults with sarcopenic obesity (muscle loss plus excess fat) improve their body composition and physical function. About 380 people aged 65 and older will take part. The goal is to find effective ways to manage this condition and reduce health risks.
