Bone Mass
Like the rest of our body, 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 (particu-
larly 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 affect your 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.
AMR
The active metabolic rate (AMR) is the amount of energy that an active body consumes each day. An individual'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
Body Mass Index (BMI)
BMI is a number often used to evaluate body weight. The figure is calculated from body weight and height.
The formula is: body mass index = body weight/height². The measurement unit for BMI is [kg/m²]. According to
BMI, weight is classified for adults (20 years and over) using the following values:
