electrical resistance. Eating and drinking habits dur-
ing the course of the day and individual lifestyle
affect the water balance. This is noticeable by the
fluctuations in the display.
In order to ensure that the results of analysis are
a accurate and consistent as possible, keep the
measurement conditions constant, as only in this
way will you be able to observe changes over an
extended period.
Other factors can affect water balance:
After a bath, the body fat reading may be too low
and the body water reading too high.
After a meal, readings can be higher.
Women may experience fluctuations due to the
menstrual cycle.
