Lean body mass, or LBM, is a measurement of the amount of muscle, bone, and organs in your body. Measuring LBM is important for understanding your overall body composition and health. A higher LBM is associated with better health outcomes, including increased strength, mobility, and metabolism. In the past, measuring LBM was limited to expensive lab equipment and procedures. However, today there are several methods that can be used to measure LBM at home.
Advancements in technology have made it possible to estimate LBM using home scales and handheld devices. These devices use bioelectrical impedance analysis (BIA), which sends a small electrical current through your body to measure the amount of resistance. BIA devices are relatively inexpensive, easy to use, and can provide a reasonable estimate of LBM.
