Working PrinciplesAs electrical signal of certain frequency transmits through human body, theimpedance of fat is stronger than that of muscle or other human tissues.Through the use of biological resistance analysis, this product will pass asafe frequency of low voltage electrical current through human body, thus,the Fat% will be reflected according to the resistance differences when theelectrical signal transmitting through human body.3.

Calorie & Losing WeightControl the calorie intake combined with proper exercise is an effective wayto lose weight. This is a very simple theory. As the daily energy intake cannot support the energy consumption of the human body, the saccharide andfat stored inside will decompose and provide energy to human body.That leads to weight loss.Calorie: Energy UnitThe data reading indicates the energy you need to sustain the daily metabolismand ordinary activities required for your weight, height, age and sex.Cleaning & Maintenance1.
