What is the body fat scale based on to detect the body fat rate?

Muscle contains more water such as blood, which can conduct electricity, but fat can't. Because the channel conductor of current in the body is muscle, the weight of muscle can be known from the difficulty of current passing, so as to judge the proportion of muscle in the weight.

Matters needing attention in the use of body fat scale

1, if wearing shoes or socks, standing on the weighing scale can also measure body fat, it means that weighing scale will not emit electricity at all. The real body fat scale can't measure the body fat rate through shoes, socks or plastic bags.

2. Real body fat scale, whether feet are wet or not will also lead to abnormal resistance during measurement, which will lead to a sudden change in body fat rate.

3. The body fat rate measured by normal body fat scale will change greatly in the morning and evening.

Extended data:

A healthy body lies in the balance of body fat. Too much fat accumulation is harmful to the body, leading to various diseases. Human fat is an important part of the human body, which has important functions and functions in the human body, such as providing energy, protecting internal organs, maintaining body temperature, assisting the absorption of water-soluble vitamins, and participating in human metabolic activities. However, too much fat will affect human health, leading to diabetes, cardiovascular and cerebrovascular diseases.

According to the above principle, the electronic body fat scale uses the electrode on the surface of the body fat scale to contact the user's leg, and measures the human body resistance through a certain safe current. Then, based on the input user data and the measured human resistance, we can accurately measure human body components such as body fat percentage, body water percentage, body muscle percentage and bone weight by using a large number of formulas obtained from experiments.
