Muscle percentage
The muscle percentage measurement measures the skeletal muscle mass. No organ muscles are taken into
account. 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. Note that this scale identifies the mineral content of the bone. 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
Mifflin St. Jeor equation.
This is the amount of energy that is required by your body under all circumstances and must be re-supplied to
the body in the form of food. If your energy intake is below this level in the longer term, this can result in damage
to health.
AMR
The active metabolic rate (AMR) is the amount of energy that the active body consumes each day. An individual's
energy requirement increases when the level of physical activity increases; the diagnostic bathroom scale calcu-
lates this by means of the activity level (1–5) that has been entered.
To maintain the current weight, the energy that the body uses must be replaced in the form of food and drink. If
less energy is taken in than is used over a long period of time, the body primarily takes the difference from the fat
stores with resulting weight loss. However, if the amount of energy taken in exceeds the calculated active meta-
bolic rate (AMR) for a longer period, the body cannot burn off the excess energy. The excess is stored in the body
as fat, leading to weight gain.
