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%
Body fat contains relatively little water. Therefore persons with a high body fat percentage have body water 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 concerning age-related water retention. If
necessary ask your physician. Basically, a high body water percentage should be the aim.
Muscle percentage

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 = Basal Metabolic Rate /
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-Benedict 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.
