Tanita Body Fat Monitor/Scales use BIA (Bioelectrical Impedance Analysis) technology. This method of body fat analysis is very accurate and easy to use; however, changes in hydration levels can affect readings. If your body is dehydrated, you will likely experience a higher fat percentage than normal. If you are over-hydrated, you could experience a slightly lower fat percentage.
