Description

Body fat analyzer and measuring method {A BODY IMPEDANCE MEASURING DEVICE AND THE BODY IMPEDANCE MEASURING METHOD}

The present invention relates to an apparatus and a method for measuring a body fat analyzer, and more particularly, to a body fat analyzer and a method for measuring body fat, which is easy to carry and facilitates measurement of body fat of a user through a palm-to-palm of a user.

The body consists of four main components: body water, protein, body fat, and minerals. In general, obesity refers to a state of overweight, but precisely, a state in which a relatively large amount of fat is broken due to a balance between two components of energy-using muscle and energy-releasing body fat. Obesity is often diagnosed as the ratio of body fat mass to body weight, ie body fat percentage. Excluding body fat, body weight is mostly determined by skeletal and muscle mass, so body fat percentage is determined by the ratio of muscle mass and body fat mass.

If the amount of body fat is higher than the standard value or the muscle mass is lower than the standard value, the body fat rate increases. Obesity is not just determined by weight alone, and slim young women may be judged as obese if they lack muscle mass despite low weight. Therefore, it is also used as a means of quantitatively measuring the components constituting such a body and measuring the mutual ratio of them repeatedly to determine the therapeutic effect.

Hereinafter, a conventional body fat analyzer and a measuring method will be described.

By measuring in this way, it is possible to remove the unnecessary resistance value that may occur in the measurement process, the user can measure the body fat meter in a comfortable posture.

The main control unit 104 calculates the body fat percentage of the user by calling the body fat analyzer data according to the resistance value stored in the memory unit 105 based on the received resistance value. The main controller 104 interlocks the display unit 106 and generates a control signal to display the calculated user body fat result value on the display window 150. In this case, the main controller 104 may store the calculated data in the memory 105, and the present invention is not limited only to the embodiment.
