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:
Man
Woman
Age low normal high
10-14 <44% 44-57% >57%
15-19 <43% 43-56% >56%
20-29 <42% 42-54% >54%
30-39 <41% 41-52% >52%
40-49 <40% 40-50% >50%
50-59 <39% 39-48% >48%
60-69 <38% 38-47% >47%
70-100 <37% 37-46% >46%
Age low normal high
10-14 <36% 36-43% >43%
15-19 <35% 35-41% >41%
20-29 <34% 34-39% >39%
30-39 <33% 33-38% >38%
40-49 <31% 31-36% >36%
50-59 <29% 29-34% >34%
60-69 <28% 28-33% >33%
70-100 <27% 27-32% >32%
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 buil-
ding, 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-Be-
nedict 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.
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 dia-
gnostic 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 reduce. If, on the other
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.
