Body fat contains relatively little water. Therefore people with a high body fat percentage have body water per-
centages 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.
Muscle percentage
As the percentage of muscle differs from individual to individual, there are no generally valid guidelines.
Bone mass
This feature indicates the amount of bone (bone mineral level, calcium or other minerals) in the body. 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 nutrition (par-
ticularly calcium and vitamin D) and regular exercise. With appropriate muscle building, you can also strengthen
your bone structure.
Do not confuse bone mass with bone density. Bone density can be determined only by means of a medical
examination (e.g. computer tomography, ultrasound). It is therefore not possible to draw conclusions concerning
changes to the bones and bone hardness (e.g. osteoporosis) using this scale. Only small changes to bone mass
are possible by individuals, but it will vary slightly within the influencing factors (weight, height, age, gender).
Active metabolic rate
The Active Metabolic Rate (AMR) is the amount of energy required daily by the body in its active state. This AMR
value is displayed automatically as soon as you select your user data symbol
under settings.
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 reduce. If, on the other hand, over a longer
period of time more energy is introduced than the total active metabolic rate (AMR) calculated, your body will be
unable to burn off the excess energy, and the excess will be stored in the body as fat and your weight will increase.
8. Interpretation of results
Remember that only long-term trends are important. Short-term fluctuations in weight over a few days are usually
the result of fluid change, due to fluid intake or loss. Interpretation of the results will depend on changes in your
overall weight and body fat, body water and muscle percentages, as well as the period in which these changes
take place. Sudden changes within days must be distinguished from medium-term changes (over weeks) and
long-term changes (months).
A basic rule is that short-term changes in weight almost exclusively represent changes in water content, whereas
medium and long-term changes may also involve the fat and muscle percentages.
• If your weight reduces over the short term, but your body fat percentage increases or remains the same, you
have merely lost water – e.g. after working out, a sauna session, or a diet focused solely on rapid weight loss.
• If your weight increases over the medium term and the body fat percentage falls or stays the same, then you
may have increased valuable muscle mass.
• If your weight and body fat percentage fall simultaneously, then your diet is working – you are losing fat mass.
• Ideally you should support your diet with physical activity, fitness or power training. This way you can increase
your muscle percentage over the medium term.
• Body fat, body water, or muscle percentages should not be added (certain elements of muscle tissue also
contain body water).
