The concept of body composition refers to the proportion of different components within the human body, mainly focusing on the ratio of fat mass to lean body mass (muscle, bones, organs). Understanding body composition goes beyond just measuring body weight; it provides insights into overall health, fitness levels, and metabolic processes. A higher proportion of lean mass often correlates with better health outcomes, such as improved physical performance and metabolic rate. Conversely, excessive body fat can lead to various health risks, including cardiovascular diseases and metabolic disorders. Therefore, assessing body composition is essential for tailored health and fitness interventions.
