Bone mass

Like the rest of our body, our bones are subject to natural growth, shrinking and ageing processes. The bone mass 

increases rapidly during childhood and reaches its peak between the ages of 30 and 40. As we age, our bone 

mass then begins to reduce. 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 skeleton can be further increased by 

means of targeted muscle build-up. Please note that this scale does not identify the calcium content of the 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 the bone mass, although it does fluctuate within the scope of influencing 

factors (weight, height, age, gender). There are no recognised guidelines or recommendations.

 IMPORTANT:

Please do not confuse bone mass with bone density.

The bone density can only be determined by means of a medical examination (e.g. computer tomography, ultra-

sound). It is therefore not possible to draw conclusions on changes to bones and bone hardness (e.g. osteoporo-

sis) 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 (e.g. when lying in bed 24 hours a day). This value is primarily dependent on weight, height and age.

It is displayed on the diagnostic scale in the unit kcal/day and calculated using the scientifically recognised Harris-

Benedict equation.

This is the amount of energy that is required by your body under all circumstances and must be re-supplied 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.

Body mass index (BMI)

The body mass index (BMI) is a number that is often called upon 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 the BMI, weight is classified for adults (20 years and over) using the following values:

Category

BMI

Underweight

Severely underweight

< 16

Underweight

16-16.9

Slightly underweight

17-18.4

Normal weight

18,5-24,9

Overweight

Overweight

25-29,9

Obese (overweight)

Class I obesity

30-34.9

Class II obesity

35-39.9

Class III obesity

≥ 40
