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 per-
formed, the training intensity and the physical constitution, the results may still be below the stated stand-
ard 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.
