What is the principle of body fat weighing? Is it necessary to buy it?

The measurement principle of body fat scale, known as BIA bioelectrical impedance measurement in the industry, is a common measurement method for almost all body fat scales, body composition meters and other measurement tools on the market at present. The specific principle is that the scale body sends out a weak current through the electrode sheet and forms a closed loop with the human body. Through the principle that muscle is easy to conduct electricity and fat is not, an electrical impedance value is obtained, and then the body fat rate is calculated by combining the data such as height and weight.

Many people think that the body fat scale is deceptive, and many data are calculated. But in fact, with the current international body fat measurement technology, it is very complicated and difficult to accurately measure body data.

This is also the main reason why BIA measurement method is widely used in industry. The answers to some questions are quite right. The use of body fat scale mainly depends on a change amount and trend, which can prove that exercise and fitness are effective. In addition, the use scene of the body fat scale is located at home. It can be weighed anytime and anywhere, and the convenience, accuracy and reference value of obtaining data are very high.

Let's talk about the main significance of the existence of intelligent body fat scale. One is to upgrade and optimize the family weighing scale. Weighing scale has a single function, and the price of body fat scale is slightly higher than that of weighing scale, but it is not outrageous. Why not choose a body fat scale with more reference data? In addition, it can also be recorded directly through the mobile APP, and it has long-term curve observation, which is an absolute advantage over the traditional weighing scale.

In addition, many friends are concerned about accuracy, and the first is whether the weight is accurate. If a weigher is not sure about the weight and the measurement error before and after is very large, it is really not fun.

Followed by data such as body fat rate, here we want to promote a dry product. Some friends think that the measurement of body fat varies greatly in different postures, such as squatting, standing normally, or standing with both feet on the ground, because the scale is not accurate, it is a fake scale.
