Body mass index (BMI)

The body mass index (BMI) is a number that is often called upon to evaluate body weight. The figure is calculated
from body weight and height. The formula is: body mass index = body weight : height². The measurement unit for
BMI is [kg/m²]. According to the BMI, weight is classified for adults (20 years and over) using the following values:
Category
Underweight
Normal weight
Overweight
Obese (overweight)

Results in relation to time

Note: Remember that only long-term trends are important. Short-term fluctuations in weight over a few
days are usually the result of a loss of fluid.
The interpretation of the results will depend on changes in your overall weight and body fat, body water and mus-
cle percentages, as well as on the period during which these changes take place. Sudden changes within days
must be distinguished from medium term changes (over weeks) and long term changes (months).
A basic rule is that short term changes in weight almost exclusively represent changes in water content, whereas
medium and long term changes may also involve the fat and muscle percentages.
• If your weight reduces over the short term, but your body fat percentage increases or remains the same, you
have merely lost water – e.g. after a training session, sauna session or a diet restricted only to rapid weight loss.
• If your weight increases over the medium term and the body fat percentage falls or stays the same, then you
could have built up valuable muscle mass.
• If your weight and body fat percentage fall simultaneously then your diet is working – you are losing fat mass.
• Ideally you should support your diet with physical activity, fitness or power training. This way you can increase
your muscle percentage over the medium term.
• Body fat, body water or muscle percentages should not be added (certain elements of muscle tissue also con-
tain body water).

7. Cleaning and care of the unit

The unit should be cleaned occasionally.Clean using a damp cloth, to which you can apply a little detergent if
necessary.

IMPORTANT:

• Do not use aggressive solvents or cleaning agents!
• Never immerse the unit in water!
