Overview of measuring
To get the most accurate absolute values, measurements should be taken while wearing
no clothing, preferably in the evening, and after urinating. If you do not undress, always
remove your socks or stockings, and be sure the soles of your feet are clean before step-
ping on the measuring platform. Stand erect on the platform. If used after bathing, the
body must be completely dry.
NOTE: Accurate measurement will not be possible if the soles of your feet are not clean, or if
your knees are bent or you are in a sitting position.
It is best to take measurements at the same time each day, preferably in the evening. If
doing so is not convenient, remember to wait about three hours after rising, eating, or
hard exercise before taking measurements. While readings taken under other conditions
may not have the same absolute values, they are accurate for determining the percentage
of change as long as the readings are taken in a consistent manner. To monitor progress,
compare weight and body fat percentage measurements taken under the same conditions
over a period of time.
