Body fat percentage

The following body fat percentages are guide values (contact your physician for further information).
Men
Age Low Normal High
10 –14 <11 11–16 16.1– 21 >21.1
15 – 19 <12 12 –17 17.1– 22 >22.1
20 – 29 <13 13 –18 18.1– 23 >23.1
30 – 39 <14 14 –19 19.1– 24 >24.1
40 – 49 <15 15 – 20 20.1– 25 >25.1
50 – 59 <16 16 – 21 21.1– 26 >26.1
60 – 69 <17 17– 22 22.1– 27 >27.1
70 –100 <18 18 – 23 23.1– 28 >28.1
A lower value is often found in athletes. Depending on the type of sports, training intensity and physical con-
stitution, 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 percentage

The body water percentage is normally within the following ranges:
Man
Age poor good
10 –100 <50 50 – 65
Body fat contains relatively little water. Therefore people with a high body fat percentage have body water
percentages 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.
Note:
If your body water proportion is rated as "poor", a
Tip: Increase your daily water intake in accordance with your physician's advice.

Muscle percentage

The muscle percentage is normally within the following ranges:
Men
Age Low Normal High
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 the natural development, degeneration and aging processes.
Bone mass increases rapidly in childhood and reaches its maximum between 30 and 40 years of age. Bone
mass reduces slightly with increasing age. You can reduce this degeneration somewhat with healthy nutri-
tion (particularly calcium and vitamin D) and regular exercise. With appropriate muscle building, you can also
strengthen your bone structure. Note that this scale will not show you the calcium content of your bones, but
will determine the weight of all bone constituents (organic substances, inorganic substances and water).
