1. Interesting facts

The measuring principle of the diagnostic scale

This scale determines the body weight, body water and the percentage of muscle according 
to the principle of Bioelectric Impedance Analysis (BIA). With this process, an imperceptible, 
completely safe and harmless current enables the determination of body tissue proportions 
within seconds. This measurement of electrical resistance (impedance) and the inclusion of 
constants and/or individual values (age, height, sex, activity levels) can be used to determine 
the percentage of fat, water and muscle in the body. Muscle tissue and water have good 
electrical conductivity, and therefore a lower resistance. On the other hand, fatty tissue has a 
low conductivity, as the fat cells hardly conduct the current due to their very high resistance.

Weighing correctly

If possible, always weigh yourself at the same time of day (ideally in the morning), after going 
to the toilet, on an empty stomach and without clothes to achieve comparable results.
Only the long-term trend counts. 
Short-term weight fluctuations within a few days are usually only due to a loss of liquid. 
However, body water plays an important role in your well-being. The interpretation of the re-
sults depends on the changes in the:
1. total weight
2. percentage of fat
3. percentage of water
4. percentage of muscle
and on the length of time during which these changes take place. Rapid changes over sev-
eral days should be distinguished from mid-term changes (over several weeks) and long-term 
changes (months). As a basic rule, SHORT-TERM weight changes almost exclusively repre-
sent changes in water content, while mid-term and long-term changes can ALSO concern 
the percentage of fat and muscle.
•  If you experience a short-term drop in weight, however the percentage of body fat increas-

es or remains the same, you have only lost water, e.g. after a training session, going to the 
sauna or following a diet limited to rapid weight loss.

•  If you experience a mid-term weight increase, while the percentage of body fat drops or 

remains the same, you might have built up your muscle mass or your body may have re-
tained more water (e.g. as the result of taking medication or a weaker cardiac function in 
elderly people).

•  If your weight and percentage of body fat drop simultaneously, your diet is working and 

you are losing fat mass. Ideally, you can support your diet with physical exercise, fitness or 
power training. This can result in a mid-term increase in the percentage of muscle in your 
body. 

And remember: Physical exercise is the basis for a healthy body.
