6.1 What is body fat percentage?
The body fat percentage is derived from the ratio between body
weight and body fat.
6.2 Measurement of the body fat percentage
To determine the body fat percentage, the BIA-method
(bioelectrical impedance analysis) has been developed.
The resistance of the body is measured while a small and
harmless electric current is sent through the body. The
resistance is higher in adipose tissue while the current flows
more easily in fat-free mass. Due to the measurement of
resistance with the body size of the person, its age and sex, it is
possible to estimate the percentage of fat and water of the
body.
The percentage of fat is influenced by the hydration of the body.
Some hours after standing up, the percentage of body fat is
influenced by the supply of water. And when you measure
yourself at different times of the day, you will also realize a
slight difference between the measured data.
