How does the body resistance depend the body fat?

Body resistance, or impedance, is influenced by body fat because fat tissue has a lower water content compared to lean tissue, which is more conductive. Higher body fat percentage typically results in increased resistance to electrical flow in the body. This is why bioelectrical impedance analysis (BIA) can be used to estimate body composition; as body fat increases, the resistance measured also tends to increase. Thus, body resistance provides insights into the proportion of fat versus lean mass in an individual.
