Body Composition Changes

Meaning

Body composition changes refer to measurable shifts in the relative proportions of the body’s primary constituents, specifically fat mass, fat-free mass (including muscle, bone, and water), and bone mineral density. These alterations are fundamental indicators of metabolic health, longevity, and overall physical function, extending far beyond simple body weight fluctuations. Clinically, monitoring these changes, particularly the progressive decline in lean muscle mass and increase in visceral adipose tissue, provides crucial insight into the aging process and the efficacy of hormonal or lifestyle interventions.
