Body fat scales are not an IQ tax, but the results are for reference only.
Many body fat scales sales page introduces at least 10 functions to start, not only can measure weight, BIM, body fat rate, moisture rate, muscle content, bone content, visceral fat, etc., but also based on the measurement data and records to generate charts and graphs report, "electronic personal trainer" will provide personalized fitness, The "electronic personal trainer" will provide personalized fitness, weight loss, plasticity, muscle building and other recommendations.
But because most home body fat scales use "bioelectrical impedance analysis", the different conductivity of fat and body weight to deduce the body's fat and muscle content. Drinking water, eating, and limited human contact with the electrode pads will all affect the test data, and the data model of different products will also affect the results.
So, for this type of smart device as a body "management", the industry suggests that it can be used for daily understanding of their own body's basic condition, and the APP's analysis of the data is only helpful for exercise and dietary reference.
Scientific use of body fat scales
Be careful not to do strenuous exercise before each measurement, and do not take measurements after eating, drinking and bathing.
While bioresistive body fat scales are subject to error, we can try to create "fixed" conditions to record changes in body fat percentage to achieve the desired results. For example, we can fix the test in the morning when we wake up with an empty stomach; we can fix the test with our feet and arms slightly open without twisting our body, and so on.
It is important to note that if your body is equipped with an electronic medical device, such as a pacemaker or respirator, it is not suitable to use a body fat scale, so as to avoid its output of low-frequency current affecting the normal operation of the medical device. It is also not necessary for pregnant women to use a body scanner, as body fat and water are generally higher during pregnancy.
