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 of
fat in 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 as follows may be used as a guide:

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 pioneered since the
seventies. 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owwithadifferent
degreeofdifculty.Thedifcultywithwhichasignalows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 will not add up to 100%.
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.
The optimal %TBW and average %SM of an individual varies according to
age and gender. The table as follows may be used as a guide:
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; lubricates joints and is a component of many
bodyuids.Theamountofwaterinthebodyuctuateswiththehydrationlevel
of the body and state of health. Monitoring the level of body water can be a
useful tool for one's health maintenance. Similar to body fat estimation, the %TBW
function provided in this scale is based on BIA.
The estimated %TBW may vary according to your hydration level, that is, how
much water you have drunk or how much you have sweated immediately prior
totheestimation.Forbetteraccuracy,avoiductuationinhydrationlevelprior
to the estimation. The accuracy of the scale in estimating TBW will also decrease
with individuals suffering from diseases that tend to accumulate water in the
body.
Please be reminded that the %TBW estimated with the scale represents only a
good approximation of your TBW. There exist clinical methods of estimating total
body water that can be ordered by your physician.
