Body Composition Improvement

Meaning

Body composition improvement is a clinical objective defined as a favorable shift in the ratio of lean body mass—including muscle, bone, and water—relative to fat mass, independent of changes in total body weight. This metric is a far more accurate and clinically relevant indicator of metabolic health and longevity than simple body mass index. Achieving this improvement is crucial for enhancing physical function and reducing the risk of chronic, age-related diseases.
