 Bioelectrical impedance analysis

Bioelectrical impedance analysis (BIA) is a method used to estimate body composition, particularly the proportion of fat mass and lean body mass (which includes muscle, water, and bone). The technique is based on the principle that different tissues in the body conduct electricity differently due to their composition. ### How It Works: 1. **Electrical Current**: A low-level electrical current is passed through the body using electrodes placed on the skin. This is safe and generally painless.
