Body composition assessment measures the fat and lean compartments of the body separately. Body weight cannot distinguish them, and a given weight change may comprise very different proportions of each.[1]

The reference methods are dual-energy X-ray absorptiometry and multi-compartment models combining several measurements. Field methods — bioimpedance, skinfolds, circumference-based equations — are more accessible and considerably less precise.[1]
