The Accuracy Of Electronic Body Fat Scales Is Not Foolproof

    At present, most of the common weight scales on the market use the "BIA bioelectrical impedance analysis method". Because the electrical conductivity of different parts of the body, such as muscle and fat, is different, fat has extremely poor electrical conductivity because it contains almost no water. When a person stands on the scale with both feet, the skin-skin electrodes contact to generate a microcurrent, which circulates throughout the body, thereby obtaining the body fat and fat content of the body. This is why we need to stand on the scale with both feet at the same time when using the scale. the foot position. In this way, the measured microcurrent can be effectively generated.

    The smart body fat scale does not focus on the number of test results, but on the improvement of the accuracy of the existing data. To this end, the smart body fat scale is equipped with a high-precision BIA chip to accurately measure human bio resistance and is equipped with up to 4 high-precision pressure sensors, which improves the detection accuracy by 5 times. On this basis, the intelligent body fat scale will also use the model algorithm to analyze the data to obtain the final indicator data, so as to customize a more reasonable training plan for the user.

    The accuracy of the body fat scale is determined by the accuracy of the algorithm for calculating the body fat percentage based on the bioimpedance value, so the manufacturer will compare the results of the measurement of the body fat scale with the underwater weighing method, dual-energy X-ray method, CT or The standard body fat rate is measured by MRI technology for comparison and verification. If the consistency is high, this body fat scale is accurate.

    But in any case, there is a certain systematic error in the body fat scale, and it is unlikely to be 100% accurate. For example, your actual body fat rate is 20%, and the body fat scale says 21%. In fact, you don’t need to worry about the 1% error.
