Bioelectrical impedance is clinically proven. It works by sending a small, imperceptible electrical signal through the whole body–from arm to arm or foot to foot–to calculate total body water.
Given the ratios of the water in your upper and lower body change throughout the day – as gravity pulls more water into your lower extremities – the electrical impedance of the body also varies.
Typically, these types of measurements could only be taken by a doctor or physical trainer. With Omron, you can get them at home, anytime you want.
