Body water percentage
The body water percentage is normally within the fol-
lowing ranges:
Man
Age poor
10 –100 <50 %
Woman
Age poor
10 –100 <45 %
Body fat contains relatively little water. People with a
high proportion of body fat may therefore have a pro-
portion of body water below the guideline values. With
endurance athletes, however, the recommended val-
ues 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 percent-
age should be the aim.
Proportion of muscle
The muscle percentage is normally within the follow-
ing ranges:
Man
Age low
10 –14 <44%
15 –19 <43%
20 – 29 <42%
30 – 39 <41%
40 – 49 <40%
50 – 59 <39%
60 – 69 <38%
70 –100 <37%

Bone mass
Like the rest of our body, our bones are subject to the
natural development, degeneration and ageing pro-
cesses. 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
nutrition (particularly calcium and vitamin D) and reg-
ular 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 measure the weight of all bone constit-
uents (organic substances, inorganic substances and
water). Little influence can be exerted on bone mass,
but it will vary slightly within the influencing factors
(weight, height, age, gender).
There are no recognised guidelines or recommenda-
tions relating to bone mass measurement.
Important
Please do not confuse bone mass with bone density.
Bone density can be determined only by means of a
medical examination (e.g. computer tomography, ultra-
sound). It is therefore not possible to draw conclusions
concerning changes to the bones and bone hardness
(e.g. osteoporosis) using this scale.
BMR
The basal metabolic rate (BMR) is the amount of ener-
gy which the body requires to maintain its basic func-
tions when completely at rest (sufficient for e.g. lying
in bed for a period of 24 hours). This value essentially
depends on weight, height and age. The diagnostic
scale displays this in kcal/day and calculates it using
the scientifically recognised Harris Benedict formula.
This is the amount of energy that your body requires as
an absolute minimum which must be supplied to the
body in the form of food. If you consume less energy
than this in the long term, it can have a detrimental ef-
fect on your health.
AMR
The active metabolic rate (AMR) is the amount of ener-
gy required daily by the body in its active state. The en-
ergy consumption of a human being rises with increas-
ing physical activity and is measured on the diagnostic
scale in relation to the degree of activity entered (1 – 5).
To maintain your existing weight, the amount of energy
used must be reintroduced into the body in the form
of food and drink. If less energy is introduced than is
used over a longer period of time, your body will obtain
the difference largely from the amount of fat stored and
your weight will decrease. If, on the other hand, over a
longer period of time more energy is introduced than
the total active metabolic rate (AMR) calculated, your
