Calculating lean body mass (LBM) is a crucial step in assessing body composition and health status, particularly for men. LBM represents the metabolically active tissue in the body, excluding fat mass.
Understanding LBM is essential for fitness professionals, nutritionists, and individuals seeking to optimize their health. It provides insights into muscle mass, bone density, and overall metabolic function. Historically, the development of bioelectrical impedance analysis (BIA) in the 1990s significantly improved the accuracy and accessibility of LBM measurements.
