2. How is percentage Body Fat (%BF) estimated?
The percentage of BF is measured by a method called Bioelectrical Impedance Analysis
(BIA). The use of BIA to estimate body fat has been used since 1970. It was only in the past
decade that the estimation of body fat using BIA technology was successfully offered to
the consumer as a compact bathroom scale. With BIA technology, a low intensity electrical
signal is sent through the body. The signal is very low and causes no bodily harm.
Depending on the amount of body fat of the individual, the electrical signal will flow with
a different degree of difficulty. The difficulty in which a signal flows through the body is
called electrical impedance. Hence, by measuring the electrical impedance and applying
to the data a proprietary algorithm, %BF can be estimated. Please note that the percentage
of body fat and body water do not add up to 100%.
Please be reminded that the %BF estimated with the scale represents am approximation of your
actual body fat. There are clinical methods of estimating.
