1. Body fat scale, also known as body fat scale, refers to a model that can measure weight like traditional weighing scale. More importantly, it adopts BIA bioelectrical impedance measurement method, and accurately measures body components such as body fat percentage, body moisture percentage, body muscle percentage, bone weight, etc. according to the information data input by users and the measured human resistance, using a large number of formulas obtained from experiments. Widely used in families, hospitals, health clubs and so on.
2. Measurement method of body fat scale: The user stands barefoot on the body fat scale (because human skin is in contact with the measuring electrode), and a weak current passes. According to the law that the body fat is not conductive and the body water is conductive, a resistance value is measured, and then it is calculated according to the user's height, age and gender, and brought into the big data sample model. Of course, the current passing through the human body is very weak and harmless to the human body.
3. At present, there are many methods to measure human body composition, especially human body fat, mainly including underwater weighing method, skinfold meter method and bioelectrical impedance analysis method. In addition, there are dual-energy X-ray absorption, computed tomography and magnetic resonance, which have developed rapidly in recent years, but these methods require expensive equipment and professional training, and patients are vulnerable to radiation, so they are not suitable for home use. BIA method is convenient to use, accurate in measurement results and relatively low in price, which is favored by consumers.
4. According to BIA theory, BIA is a technology to design and estimate body composition according to different conductive characteristics of different body tissues. When a current with a frequency greater than 50kHz is applied to the body tissue, the current can pass through the extracellular fluid. But part of the current will be absorbed by the cell membrane (resistance, R); Part of the current slows down because the cell membrane is temporarily charged, which is the reaction. Impedance (z) is the sum of resistance and resistance, and usually resistance accounts for more than 90%.
5. According to the above principle, the electronic body fat scale uses the electrode sheet 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 body resistance, we can accurately measure human body components, such as body fat percentage, body moisture percentage, body muscle percentage, bone weight and so on, by using the formulas we have obtained in a large number of experiments.
6. When users use the body fat scale, data such as body fat, muscle rate and moisture will be presented. But display is not the purpose, the real meaning lies in the comparison of trends. For example, due to many factors such as diet, exercise and intestinal contents, users will have several kilograms of weight fluctuations all day. Depending on whether you are thin or fat, people will deliberately choose the same time and weigh under the same conditions. So most users choose to get up in the morning or go to bed at night to see the fluctuation of weight data.
How does the body fat scale measure energy on time? It is to get up early on an empty stomach, go to the toilet to clean, wear thin clothes, keep your hands and feet dry and then weigh. In this case, the measurement is relatively accurate. If you want to know if you are really fat, use this method to measure the body fat rate for three days in a row, and then take an average and compare it with the body fat rate three days ago. It is higher than three days ago, and the probability of gaining weight is high; It's lower than three days ago, and it's possible to lose fat.
