Functionality

The body fat scale displays the percentage of muscle mass, body fat, body water and
bone mass in relation to total body weight. The standing area of the scale has electrodes
which measure body fat by means of the body's electric resistance. Lean body tissue has
a lower resistance than fatty body tissue. The scale automatically compares the body fat
measured to the person's body height, age, sex and total weight. This results in the body
fat value.

Body fat

Too much body fat is unhealthy. What is more important is that a high body fat level is
usually accompanied by an increased blood fat level and this dramatically increases the
risk of various illnesses, such as diabetes, coronary artery disease, high blood pressure,
etc.
However, if the body fat percentage is too low this is also unhealthy. In addition to
subcutaneous fat tissue, the body also creates important fat deposits to protect internal
organs and safeguard important metabolic functions. If these essential fat reserves are
used, it can lead to metabolic disorders, for instance, an increased risk of osteoporosis.
The normal body fat level varies with age and gender. The normal value for women is
around 10% higher than for men. As we get older, our bodies break down muscle mass
and this increases the body fat level.
