Bone mass
Like the rest of our body, our bones are subject to natural growth, shrinking and aging processes. Bone
mass increases rapidly during childhood and reaches its peak between the ages of 30 and 40. As we age,
our bone mass begins to decrease. You can combat this reduction to an extent with the help of a healthy
diet (particularly calcium and vitamin D) and regular physical exercise. The stability of the skeletal system
may be increased through muscle buildup. Note that this scale does not measure calcium content of bones;
instead, it calculates the weight of all the components that make up the bones (organic matter, inorganic
matter and water). It is very difficult to influence bone mass, although it does fluctuate within the scope of
influencing factors (weight, height, age, gender). There are no recognized guidelines or recommendations.
IMPORTANT:
Do not confuse bone mass with bone density.
Bone density can only be determined by a medical examination, so you cannot 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
maintain its basic functions. This value primarily depends on weight, height and age. It is displayed in kcal/
day and calculated using the scientifically recognized Harris-Benedict equation. This is the amount of energy
that is required by your body under all circumstances and must be resup plied to the body in the form of food.
If your energy intake is below this level long term, it can affect your health.
AMR
The active metabolic rate (AMR) is the amount of energy that an active body consumes each day. An indi-
vidual's energy requirement increases when the level of physical activity increases; the scale calculates 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 takes the difference from its
fat stores, and weight loss results. 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.
Context of results over time
NOTE:
Only long-term trends are important. Brief deviations in weight within a few days are normally caused
by loss of fluids.
Interpretation of these results is based on changes in total body weight, percentage of body fat, body water
and muscle content, as well as the length of time over which these changes occur. Rapid changes within the
