Body composition measurement focuses on the proportion of fat, muscle, and bone in the body, rather than just body weight like traditional weight assessments. Assessing body composition provides a clearer understanding of health and fitness by distinguishing between these components, which can influence metabolism and health risks. Body weight alone can be misleading, as it doesn’t account for muscle mass, which weighs more than fat. Therefore, body composition is critical for creating more effective health and fitness strategies that reflect one’s true physical status.
