Why measure Body Fat and Water?
Obesity is the excess accumulation of fat in the body.
Ordinary weighing scales
will show if a person is heavy, but not if they are obese. For example,
a heavy sportsperson probably has a higher proportion of muscle to fat in their
body and is not obese.
To judge obesity, the amount of body fat needs to be
measured.
Losing weight can make you fatter! Men A & B in the chart below, were the
same height and had the same body fat percentage when they started to diet
on a health programme. Each lost a total of 7 kilograms.
Although the results appear identical, Man A simply cut the number of calories
he ate. He lost weight, but his body fat percentage increased - he is actually
"fatter". Man B combined cutting calories with an exercise program. He lost the
same amount of weight as Man A but more importantly, his body fat dropped.

Proper hydration is essential for maintaining a healthy body and a good level of
energy and concentration. It is commonly accepted that if you feel thirsty, your
body is already mildly dehydrated and you need to drink some fluid, preferably
water.
Monitoring your body water percentage helps you maintain a good
level of hydration.
About body fat, water, muscle, bone percentage and BMI measurement
The Propert Glass Body Analysis Scale measures body fat, water, muscle and
bone content using Bioelectrical Impedance Analysis (BIA).
In simple terms, a
low electrical impulse (which cannot be felt) is sent through the body. It passes
easier through fluids in muscle tissue & blood than through fat tissue, which has
a higher electrical resistance. Using a formula and the information on your
gender, height, age and your calculated weight, the scale is able to compute
your body fat, water, muscle and bone mass content.
As shown in the accompanying tables, the percentage of body fat in the body
can vary dramatically depending on gender & age.
The bone mass reading is an estimate of the calcium content in the bones.
It is
not a precise medical figure and is only meant to give an indication of bone
mass.
BMI is defined as the key index for relating a person's body weight to their
height and correlates strongly (in adults) with total body fat content.
It is a
widely used diagnostic tool to identify weight problems and associated health
risks, Some muscular people may have a high BMI without undue health risks.
BMI = Body weight in kilograms / height in meters squared.
Using a Body Analysis Scale
To get the most accurate readings, please take into account the following
points:
e
Take measurements more than 3 hours after waking up in the morning.
During sleep in the prostrate position, water distribution changes in the body,
so that electrical resistance in the arms & legs increases. Some movement is
required after waking up to give a stable water distribution in the body.
e
Take measurements more than 3 hours after a meal. It takes 2 to 3 hours
for a meal to be digested and distributed in the body.
e
Excessive drinking of alcohol or excessive exercise will cause dehydration,
so also take measurements more than 24 hours later.
e
Ifthe flesh of the legs touch together, a short circuit could result, so the user
needs to put some thin form of insulation between the legs to make sure the
current goes right up the legs & into the body.
e
With the Scale being used by many different people, it is advisable to wipe
the foot pads clean with methylated spirits between each user.
In general, it is best to measure your body fat, water, muscle and bone
percentage in the evening, preferably wearing only underwear, and without
having partaken of excessive eating & drinking, alcohol consumption and
exercise beforehand. Ensure that you make repeated measurements under the
same conditions.

Note:
The data tabled were gained by sampling and are only for reference.
If you have any questions about your health, please consult your doctor.
IMPORTANT:
If your body fat exceeds 50%, this scale cannot process any of the body analysis
functions.
In this case, use the scale for weighing only until body fat is reduced
to below 50% of total weight.
WARNING
Do not use this product if you have a pace maker or other internal electronic
devices.
Artificial joints may contribute to a skewed reading but the scale can still
be safely used.
Using the scale whilst pregnant:
Whilst there is no known, documented health risk,
we would advise pregnant women
to use the body analysis scale for weighing only
and use the full range of body analysis functions after delivery of the baby.
