A lower value is often found in athletes. Depending on the type of sports, training intensity and physical 
constitution, values may result which are below the recommended values stated.
It should, however, be noted that there could be a danger to health in the case of extremely low values.

Body water

The body water percentage is normally within the following ranges:

Man Woman

Age

poor

good

very good

10  -100

<50  %

50  -  65   %

>65  %

Age

poor

good

very good

10-100

<45  %

45  -  60   %

>60  %

Body fat contains relatively little water. Therefore persons with a high body fat percentage have body wa-
ter percentages below the recommended values. With endurance athletes, however, the recommended 
values could be exceeded due to low fat percentages and high muscle percentage.
Body water measurement with this scale is not suitable for drawing medical conclusions, for example con-
cerning age-related water retention. If necessary ask your physician.
Basically, a high body water percentage should be the aim.

Muscle percentage

The muscle percentage is normally within the following ranges:

Woman

Bone mass

Like the rest of our body, our bones are subject to the natural development, degeneration and ageing 
processes. 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 
 building, you can also strengthen your bone structure.
Note that this scale will not show you the calcium content of your bones, but will measure the weight of all 
bone constituents (organic substances, inorganic substances and water). 

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.
Little influence can be exerted on bone mass, but it will vary slightly within the influencing factors (weight, 
height, age, gender). 

BMR

The basal metabolic rate (BMR) is the amount of energy required by the body at complete rest to maintain 
its basic functions (e.g. while lying in bed for 24 hours). This value largely depends on weight, height and 
age. It is displayed on the diagnostic scale in kcal/day units using the scientifically recognized Harris-Ben-
edict formula.
Your body requires this amount of energy in any case and it must be reintroduced into your body in the 
form of nutrition. If you take on less energy over the longer term, this can be harmful to your health.
