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
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 natural growth, deterioration and ageing processes.
Bone mass increases rapidly during childhood and reaches its maximum value between the ages of 30
and 40. As we age, our bone mass then gradually reduces. A healthy diet (particularly one rich in calcium
and vitamin D) and regular exercise can slow down this process. The stability of the skeletal structure can
also be boosted by targeted muscle build-up.
Please note that this scale shows the mineral content of bone and not any organic substances such as
proteins or cells. It is virtually impossible to influence bone mass; yet there may be distinct fluctuations
due to certain influential factors (such as weight, height, age, gender). There are no recognised guidelines
or recommendations.
BMR
The basal metabolic rate (BMR) is the amount of energy required by the body at complete rest in order to
maintain its basic functions (e.g. when lying in bed 24 hours a day). This value is primarily dependent on
weight, height and age.
This is the amount of energy that is required by your body under all circumstances and must be re-sup-
plied 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 calculates this by means of the activity level (1–5) that has been entered.
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 metabolic 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.
Temporal context of the results
Please note that only the long-term trend is important. Brief deviations in weight within a few days
are normally caused by loss of fluids.
The interpretation of the results is based on changes in total body weight, percentage of body fat, body water
and muscle content, as well as on the length of time over which these changes occur.
Rapid changes within the scope of a few days are to be considered separately from medium-term
changes (in the scope of weeks) and long-term changes (months).
• If your weight drops in the short term but your body fat percentage increases or stays the same, you
have only lost water, for example following a training session, visit to the sauna or a diet aimed only at
fast weight loss.
• On the other hand, if your weight increases in the medium term and your body fat percentage drops
or stays the same, you may have built up valuable muscle mass.
