Note that with very muscular physiques (body builders), the BMI interpretation will show overweight.
The reason for this is that no account is taken of well above average muscle mass in the BMI formula.

Body fat

The following body fat percentages are guide values (contact your physician for further information).
A lower value is often found in athletes. Depending on the type of sports, training intensity and physical constitu-
tion, values may result which are below the recommended values stated. It should, however, be noted that there
could be a danger to health in the case of extremely low values.

Body water

According to the World Health Organization (WHO 2001), the percentage of body water should normally lie
within the following ranges:
Women: 50 – 55 %
Men: 60 – 65 %
Children: 65 –75 %
Body fat contains relatively little water. Therefore people with a high body fat percentage have body water per-
centages below the recommended values. With endurance athletes, however, the recommended values could
be exceeded due to low fat percentages and high muscle percentage.
This scale is unsuitable for measuring body water in order to draw medical conclusions concerning age-related
water retention, for example. If necessary ask your physician. Basically, a high body water percentage should
be the aim.
