Bone mass

Like the rest of our body, our bones are subject to the natural development, degeneration and ageing pro-

cesses. 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 (particularly calcium and vitamin D) and regular exercise. With appropriate muscle build-

ing, you can also strengthen your bone structure. Note that this scale will not show you the calcium con-

tent of your bones, but will measure the weight of all bone constituents (organic substances, inorganic 

substances and water). Little influence can be exerted on bone mass, but it will vary slightly within the in-

fluencing factors (weight, height, age, gender). No recognised guidelines or recommendations relating to 

bone mass measurement.

 Attention

Please 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.

AMR

The active metabolic rate (AMR) is the amount of energy required daily by the body in its active state. The 

energy consumption of a human being rises with increasing physical activity and is measured on the diag-

nostic scale in relation to the degree of activity entered (1-5). 

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 decrease. If, on the oth-

er 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.

Results in relation to time

Remember

 that only long-term trends are important. Short-term fluctuations in weight over a few 

days are usually the result of a loss of fluid.
The interpretation of the results will depend on changes in your overall weight and body fat, body water 

and muscle percentages, as well as on the period during which these changes take place. Sudden chang-

es 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 a training session, sauna session or a diet restricted only to rapid 

weight loss.

•  If your weight increases over the medium term and the body fat percentage falls or stays the same, then 

you could have built up 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 in-

crease 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).

Note 

regarding “ideal weight”:

The ideal weight is calculated from the body height and the BMI (Body Mass Index).
