Information on Measuring Body Fat
WARNING:
Do not use the scales if you use a pacemaker or another
medical implant with electronic components. The function
of the implant may be impaired by the measurement.
NOTE:
The device can only function correctly if you stand on the
contact surfaces with bare, dry feet!
The main principle of this device is based on the measure-
ment of the electric impedance within the human body. In
order to determine the actual body data, the device leads a
weak, unnoticeable electric signal through your body.
The signal is generally safe! However, please read our special
safety instructions!
The method of measurement is referred to as “bioelectric
impedance analysis” (BIA), a factor which is based on the re-
lationship between body weight and associated body water
percentages as well as on other biological data (age, gender,
body weight).
There are heavy persons with a well-balanced percentage
between fat and muscle mass, and there are seemingly slim
persons with significantly high body fat values. Fat is a factor
that puts serious strain on the body, in particular the cardio-
vascular system. Therefore, controlling both values (fat and
weight) is a prerequisite for health and fitness.
Body Fat
Body fat is an important component of the body. From
protecting the joints as a vitamin repository to regulating the
body temperature, fat plays a vital role in the body. Thus the
goal is not to radically reduce the proportion of body fat, but
rather to achieve and maintain a healthy balance between
muscle and fat.
The Importance of Water for our Health
Approximately fifty-five to sixty percent of the human body
consist of water, depending on age and gender in varying
amounts.
Water has to fulfill several tasks within the body:
• It is the building block of our cells. That means that all the
cells in our body, whether skin cells, gland cells, muscle
cells, brain cells or others, are functional only if they con-
tain enough water.
• It is a solvent for important substances in our body.
• It is a means of conveyance for nutrients, the body’s own
substances and metabolic products.
Reference values for your fitness profile can be seen in the
benchmark table. It shows the dependency of body fat data
on age and gender. Always pay attention to your body’s
water balance, which, as well as the fat level, undergoes
strong fluctuations throughout the day. Therefore, to obtain
consistent data, always measure at the same time of day.
The calculated results of the body fat and water level should
only be considered as reference values. They are not recom-
mended to be used for medical purposes. Please always con-
sult a doctor if you have questions about a medical treatment
or a diet in order to achieve a normal body weight.
