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 BMI
Underweight Severely underweight < 16
Underweight 16-16.9
Slightly underweight 17-18.4
Normal weight 18.5-25
Overweight Overweight 25.1-29.9
Obese (overweight) Class I obesity 30-34.9
Class II obesity 35-39.9
Class III obesity ≥ 40
Body fat percentage
The subsequent body fat percentages serve as a guideline (for further information ask your doctor).

40-49 <15% 15-20% 20.1-25% >25.1% 40-49 <20% 20-25% 25.1-30% >30.1%
50-59 <16% 16-21% 21.1-26% >26.1% 50-59 <21% 21-26% 26.1-31% >31.1%
60-69 <17% 17-22% 22.1-27% >27.1% 60-69 <22% 22-27% 27.1-32% >32.1%
70-100 <18% 18-23% 23.1-28% >28.1% 70-100 <23% 23-28% 28.1-33% >33.1%
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 Female
Age Poor Good Very good Age Poor Good Very good
10-100 <50% 50-65% >65% 10-100 <45% 45-60% >60%
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.
