9. Evaluating the results

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)
Body fat percentage
The subsequent body fat percentages serve as a guideline (for further information ask your doctor).
Male
Age Low Normal
10-14 <11% 11-16%
15-19 <12% 12-17%
20-29 <13% 13-18%
30-39 <14% 14-19%
40-49 <15% 15-20%
50-59 <16% 16-21%
60-69 <17% 17-22%
70-100 <18% 18-23%
A lower value will often be determined in the case of athletes. Depending on the sporting activities performed,
the training intensity and the physical constitution, the results may still be below the stated standard values.
Please note, however, that there may be a risk to health in the case of extremely low values.
Body water content
The body water content in % is normally within the following ranges:
Male
Age Poor
10-100 <50%
Body fat contains relatively little water, therefore body water content may be below the standard values in
persons with a high body fat percentage. On the other hand, endurance athletes may exceed the standard
values due to having low levels of fat and a high muscle percentage.
The body water calculation performed using this scale is not suitable for drawing medical conclusions,
for example in the case of age-related water retention. Consult your doctor where necessary. A high body
water content is generally desirable.
