Tanita's bioelectrical impedance analysis (BIA)

Tanita's bioelectrical impedance analysis (BIA) measures body composition by sending a safe, low-level electrical current through your body. Since different tissues—like muscle, fat, and water—conduct electricity differently, the device detects resistance to the current. By analyzing this resistance along with your personal data (age, height, gender), Tanita estimates various metrics such as body fat percentage, muscle mass, and hydration levels. This method provides a quick, non-invasive way to assess body composition accurately, helping individuals track health and fitness progress over time.
