Body composition

Topic

In physical fitness and medicine, body composition refers to the relative proportions of different components—such as fat, bone, water, and muscle—that make up the human body. It is a key indicator of overall health and physical fitness, as two individuals of the same weight and height can have vastly different body types and health profiles depending on their ratio of fat to lean mass. Common methods for measuring body composition include bioelectrical impedance analysis (BIA), dual-energy X-ray absorptiometry (DEXA), and skinfold measurements.
