Bone mass

Like the rest of our body, our bones undergo natural processes of growth, breakdown and ageing. Bone 

mass increases rapidly during childhood and reaches its peak between 30 and 40 years. As you age, your 

bone mass starts to gradually decline. If you have a healthy diet (particularly calcium and vitamin D) and 

regularly exercise, you can slow this process down. You can also strengthen the stability of your skeletal 

structure using targeted muscle growth. Please note that this scale does measure minerals of bones. Bone 

mass is very difficult to modify but does vary slightly as a result of influencing factors (weight, height, age, 

sex). There are no recognised guidelines and recommendations available.

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 recog-

nised Harris-Benedict equation.

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

plied 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.

AMR

The active metabolic rate (AMR) is the amount of energy that the active body consumes each day. An indi-

vidual’s energy requirement increases when the level of physical activity increases; the diagnostic 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 the fat 

stores with resulting weight loss. 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.

Temporal context of the results

Please note that only the long-term trend is important. Brief deviations in weight within a few days 

are normally caused by loss of fluids.

The interpretation of the results is based on changes in total body weight, percentage of body fat, body water 

and muscle content, as well as on the length of time over which these changes occur.

Rapid changes within the scope of a few days are to be considered separately from medium-term 

changes (in the scope of weeks) and long-term changes (months).

It can be said as a basic rule that short-term changes in weight are almost entirely changes in water content, 

whereas medium-term and long-term changes may also relate to the fat percentage and the muscle percentage.

•  If your weight drops in the short term but your body fat percentage increases or stays the same, you 

have only lost water, for example following a training session, visit to the sauna or a diet aimed only at 

fast weight loss.
