Assessing the measured values
Body fat percentage (BF)
The values for the body fat are shown on the display and assessed as 'low', 'normal', 'high' or 'very high' and depend on your age and sex. The per-
centage of body fat is normally within the following ranges (please contact your doctor for more information):
Male
low
Normal
Age

10–14
<11

70–100
<18
18–23
A lower value is often measured for athletes. Depending on the type of sport, the intensity of training and your physical constitution, values can
be measured that are further below the guidelines indicated. Please note that there may be health risks associated with extremely low values.
Body water percentage
The percentage of body water is normally within the following ranges:
Male
low
normal
good
<50
50–65
>65
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

Bone mass
Like the rest of our body, our bones undergo natural processes of growth, breakdown and ageing. Bone mass increases rapidly during childhood and
reaches its peak between 30 and 40 years. As you age, your bone mass starts to gradually decline. If you have a healthy diet (particularly calcium and
vitamin D) and regularly exercise, you can slow this process down. You can also strengthen the stability of your skeletal structure using targeted muscle
growth. Please note that this scale does measure minerals of bones. Bone mass is very difficult to modify but does vary slightly as a result of influencing
factors (weight, height, age, sex). There are no recognised guidelines and recommendations available.
Do not confuse bone mass with bone density. Bone density can only be determined using a medical examination (e.g. computed tomography,
ultrasound). Drawing any conclusions about changes to the bone and bone hardness (e.g. associated with osteoporosis) is not possible using this
scale.
Active metabolic rate (AMR)
The active metabolic rate (AMR) is the quantity of energy that the body consumes each day in the active state, that is, the calorie requirements in kcal per
day used for activity. The energy consumption of a human rises with increasing physical activity and is determined by the level of activity (1–5) entered on the
scale. To maintain your current weight, the energy consumed must be supplied to the body in the form of food and drink. If over a longer period less energy is
supplied than is consumed, the body essentially obtains the difference from the fat stores and the weight decreases. If, however, more energy is supplied than
the calculated active metabolic rate (AMR) over a longer period, the body cannot burn up the excess energy. The excess is stored by the body as fat and the
weight increases.
Time dependence of the results
Please note that only the long-term trend is important. Short-term weight variations over a few days are usually caused by loss of fluid.
The importance of the results is determined by the changes in the total weight and the percentage of fat, water and muscle in the body as well as the
time over which these changes occur. Rapid changes over a few days must be differentiated from moderate changes (over weeks) and long-term chang-
es (months). The basic rule is that short-term changes in weight almost exclusively reflect changes in the water balance while medium-term and long-
term changes can also reflect the fat and muscle percentage.
