NOTES­ON­MEASUREMENTS
Total­body­water
Water is an essential part of the body. The
amount of water in the body may vary between
35% and 70%. It helps all the essential biochemi-
cal reactions necessary for normal bodily func-
tions. Water transports waste products out of the
cells and discharges them in sweat and urine.
Water also maintains a constant body tempera-
ture. The amount of water in the body depends
on the proportion of water loss, for example due
to heat or physical activity and sweating. There-
fore, it is very important to check the proportion
of water in the body and ensure that it remains
constant.
Notes
The following tables give you a reference
7
which can help you to judge your body fat and
body water yourself. There is no standard ref-
erence data for muscle mass or bone weight.
It is important to see and follow the develop-
7
ment of your body fat, body water, muscle
mass and bone weight over a period rather
than concentrate on the body weight only.

Body­fat­composition
Checking the body fat composition is particularly
important. A high fat mass can lead to high blood
pressure, high cholesterol, heart disease and
other illnesses. The American College of Sports
Medicine have made the following recommenda-
tions for body fat mass:
Notes
Measure body weight, body fat percentage
7
and water proportion at the same time every
day, preferably in the evening.
Use the scales when you are undressed if pos-
7
sible. This will give you more exact results.
The results are not suitable for diagnosing medi-
7
cal problems. If in doubt, seek medical advice.
Your feet should always be clean and dry.
