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 per-
sons 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 exam-
ple in the case of age-related water retention. Consult your doctor where necessary. A high body water content is
generally desirable.
Muscle percentage
The muscle percentage is normally within the following ranges:
Male
Age Low Normal
10-14 <44% 44 – 57 %
15-19 <43% 43 – 56 %
20 – 29 <42% 42 – 54 %
30 – 39 <41% 41– 52 %
40 – 49 <40% 40 – 50 %
50 – 59 <39% 39 – 48 %
60 – 69 <38% 38 – 47 %
70-100 <37% 37 – 46 %
Bone mass
Like the rest of our body, our bones are subject to natural growth, shrinking and ageing processes. Bone mass
increases rapidly during childhood and reaches its peak between the ages of 30 and 40. As we age, our bone
mass then begins to reduce. You can combat this reduction to an extent with the help of a healthy diet (particu-
larly calcium and vitamin D) and regular physical exercise. The stability of the skeleton can be further increased
by means of targeted muscle build-up. Please note that this scale does measure minerals of bones. It is very
difficult to influence the bone mass, although it does fluctuate within the scope of influencing factors (weight,
height, age, gender). There are no recognised guidelines or recommendations.
Important
Please do not confuse bone mass with bone density. The bone density can only be determined by means of a
medical examination (e.g. computer tomography, ultrasound). It is therefore not possible to draw conclusions on
changes to bones and bone hardness (e.g. osteoporosis) using this scale.
BMR
The basal metabolic rate (BMR) is the amount of energy required by the body at complete rest in order to main-
tain its basic functions (e.g. lying in bed 24 hours a day). This value is primarily dependent on weight, height and
age. It is displayed on the diagnostic scale in the unit kcal/day and calculated using the scientifically recognised
Harris-Benedict equation.
