Electronic body fat scales are devices that can measure weight and body composition at home. "Body composition" refers to the relative percentage of body fat, muscle, and water. So is the body fat scale accurate?

    The main advantage of using a body fat scale at home is convenience. In addition, as long as the weight measurement is accurate, even if the body fat measurement is biased, it can help the user to roughly track the effect of exercise or diet.

    Body fat scales are relatively accurate, but there are certain systematic errors in body fat scales, which are unlikely to be 100% accurate.

    The principle of the body fat scale is that the body fat rate is indirectly calculated or estimated, rather than directly measured like body weight, which fundamentally leads to the existence of errors.

    The scale body of the body fat scale sends a weak current into the human body through the electrode sheet. The micro current enters the human body from one foot, and after conduction in the body, the data is transmitted back to the electrode sheet under the other foot. The human body and the scale body form a closed In this way, an electrical impedance value is obtained, and then the electrical impedance value is combined with data such as height and weight to calculate the body fat percentage. There are many ways to measure body fat, the common ones are: skinfold measurement, girth measurement, dual energy X-ray absorptiometry, water densitometry, air displacement plethysmography, 3D body scan and body fat scale.
