Body fat scale can measure not only weight, but also fat, moisture and so on. Most body fat scales in the market use bioelectrical impedance method. The principle is: assuming that the human body has only two components, namely muscle and fat, muscle has high water content and is easy to conduct electricity, while fat has low water content and is not easy to conduct electricity, so the resistivity of muscle and fat is different. When low frequency or direct current passes through biological tissue, the current will bypass the cell tissue, while high frequency current will pass directly through the cell. When a person stands barefoot on the weighing scale, as long as a fixed current is input, the fat and muscle content of the human body can be judged by the difficulty of the current passing through.

A correct view of health

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.

In addition, obese patients often face various troubles such as fear of heat, influence on body shape and fatigue. Therefore, doctors and experts suggest keeping your body shape within a certain range.

With the improvement of people's living standards, health problems are paid more and more attention, which also promotes the development of human body composition measurement science.
