IMPORTANT INFORMATION TO KNOW
BEFORE USING YOUR BODY FAT SCALE
Before using the scale, you should know...
ABOUT BODY FAT
1. Why is it important to monitor percentage body
fat (%BF)?
The absolute weight traditionally determines whether
or not a person is obese. Weight change in itself does
not indicate whether it was the weight of body fat or
muscle that had changed. In weight management, it
is desirable that muscle mass be maintained while
body fat is lost. Thus, monitoring the percentage fat
of the body is an important step toward successful
weight management and body health. The optimal
%BF of an individual varies according to age and
gender.
The table that follows may be used as a guide:

2. How is percentage body fat (%BF) estimated?
%BF is measured by a method called Bioelectrical
Impedance Analysis (BIA). The use of BIA to estimate
body fat has been pioneered since the seventies. It
was only in the past few years that the estimation of
body fat using BIA technology was successfully offered
to the consumers as a compact bathroom scale.
With the 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 with
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 be reminded that the %BF estimated with
the scale represents only a good approximation of
your actual body fat. There exist clinical methods
of estimating body fat that can be ordered by your
physician.
ABOUT BODY WATER
3. Why is it important to monitor percentage
Total Body Water (%TBW) in the body?
Water is an essential component of the body and its
level is one of the health-indicators. Water makes up
approximately between 50-70% of the body's weight.
It is present proportionally more in lean tissue
compared to fat tissue. Water is a medium for
biochemical reactions that regulate body functions.
Waste products are carried in water from cells for
excretion in urine and sweat. Water provides form to
cells; helps to maintain body temperature; provides
moisture to skin and mucosa; cushions vital organs;
