How is the body fat rate measured?

Body fat scale mainly uses BIA (Bioimpedance Analysis) bioelectrical impedance measurement principle to measure our body fat. That is, when the human body stands on the electrode plate of the body fat scale, the body fat scale will send out a weak current through the electrode plate and form a closed circuit with the human body.

This circuit will pass through muscles, fat and other parts of the human body, but only muscles and water can conduct electricity in the human body, not fat. At this time, the body fat will get an electrical impedance value according to the strength of the current in this closed circuit, and then calculate the prepared body fat rate according to the gender, age, height and weight of the tester.

Extended data:

The percentage of body fat can be calculated by calculating the body mass index. Calculation method of body mass index:

1, body mass index = weight (kg) ÷ (height × height) (m)

2. Body fat rate: 1.2× body mass index +0.23× age -5.4- 10.8× sex (male 1, female 0).

The body fat rate of normal adults is 15%~ 18% for men and 25%~28% for women. The body fat rate should be kept within the normal range.

If the body fat rate is too high and the weight exceeds 20% of the normal value, it can be regarded as obesity.
