For a Correct Measurement

Body fat is affected by the change of water
content in the body.
A person's hydration level and blood circulation may have an effect
on their body fat reading. In the table below are some situations
which could affect the reading.
Cause of Fluctuations
Water and food intake
Changes in blood circulation
Change in posture (during
measurement)
The diagram below shows an example of the changes in body fat throughout
the day caused by a change of water content in the body. The changing pattern
of body fat percentage varies for each person. In order to obtain highly reliable
readings, please note the following pages.
