HOW DOES THE GoWISE USA BODY FAT SCALE WORK?
This GoWISE USA body fat scale uses Bio Impedance Analysis (BIA) technology which passes an
electrical current through the body to body fat mass, total body water, lean mass, and
bone mass. The electrical current is small and may not be felt. Contact is made with the body
via stainless steel pads on the m of the scale.

NOTE: This device is a personal monitor and should be used in a consistent manner for the
most accurate readings. While readings ohis analyzer might be differen han that of other
scales (hydro-densitometry or hand held calipers), your changes in body fat percentage shown
by this product will be reflected accurately.
IMPORTANT: The informaon provided by this device is NOT meano treat, cure, or prevent
any disease or illness. This device should NOT be used by anyone who is acutely or chronically ill,
suffering from a disease, or taking medicaons that affect your water levels. The accuracy of
readings for these paents has not been verified.Specific medical advice should be obtained
from a physician.
CAUTION:This scale is NOT intended for use by pregnantwomen or childrenunder the age of 18.
It should also NOT be used by anyone with an implanted medical device (such asapacemaker,
metal plates or screws; or contracepve devices). Ifin doubt, contact your physician.
This analyzer will work accurately as a scale for anyone, within the specificaons and warnings
noted above, and give accurate body fat readings for the majority of people.
BODY FAT – WHAT DOES IT MEAN?
Human body is made up of, among other things, a percentage offat. Body fas an important
component of a healthy and funconing body because it protects vital organs, helps regulate
body temperature, stores vitamins, and helps the body sustain itself when food is scarce.
However, too much body fat or too lile body fat can cause damage to your health. Isdifficult
to gauge how much body fat we have in our bodies simply by looking at ourselves in the mirror.
This is why is importano measure and monitor your body fat percentage. Body fat
percentage gives you a beer measurement offitness than weight alone; the composion of
your weight loss could mean you are losing muscle mass rather than fat—you could sll have a
high percentage offat even when a weight-only scale indicates ‘normal weight’.

1. Ideal body fat contens NOT the same for all people. Age, sex, and heredity are
variables in this measurement. The table thaollows is a general guide. Consult your
physician to determine whas mosdeal for you.
2. Is recommended to measure body fat and weight daily ahe same me.
3. Use this product without clothing for best accuracy. Clothes can vary in weight and
affec he percentage calculaon.
4. Feet must be bare and clean. For best readings, they should also be slightly damp.
BODY WATER – WHY MEASURE IT?
Body water is the single mosmportant component oody weight. It represents over half of
your total weight and almoswo thirds of your lean body mass (predominantly muscle).
Water performs a number ofimportant roles in the body. All the cells in the body (whether in
the skin, glands, muscles, brain, or anywhere else) can only funcon properly ihey have
enough water. Water also plays a vital parnregulang the body’s temperature balance,
parcularly through perspiraon. The combinaon of your weight and fat measurement could
appear to be ‘normal’, but your body hydraon level could be insufficien or healthy living.
LEVEL OF HYDRATION
This scale measures your weight and the electrical impedance between your feet--and then
combines those readings with the personal informaon you entered (Height, Age, Gender). It
then automacally calculates your body fat percentage. Your level o ydraon (water content)
varies throughouhe day and affects your impedance measurement. If you are dehydrated,
there is a greater chance for fluctuaon in the body fat percentage displayed by this scale than
when you are fully hydrated.
For best results, choose a consistenme to use this analyzer, such as in the morning. By
establishing the paern of your body’s fluctuaon over a period of one month, you can
determine your average level oody fat. Women will have more fluctuaon in water content
than men and need to monitor their reading over a longer period to establish a personal
average. You must determine this as a reference point before measuring progress in a health
program.
You must wait severalhoursbefore taking a bodyfat readingwhen:Drinking coffee or alcohol,
taking diurecmedicaons, or exercising. These all affect your level o ydraon and the
accuracy ohis scale.

Body water measurement results are influenced by the n of body fat and muscle. If
the n of body fat is high, or the n of muscle is low, then the body water
results will tend to be low.
It is important to remember that measurements such as body weight, body fat and body water
are tools for you to use as part of your healthy lifestyle. Since short term s can be
normal, we suggest that you chart your progress over , rather than focus on a single day’s
reading. Consult your physician to determine what is most ideal for you.
MUSCLE MASS – WHY SHOULD I KNOW IT?
According to the American College of Sports Medicine (ASCM), lean muscle mass may decrease
by almost 50 percent between the ages of 20-90. An y lifestyle can cause loss
of lean body mass while body fat increases. It’s also important to know your muscle mass
percent during weight At rest, the body burns approximately 110 calories
for each kilo of muscle gained. Benefits of gaining muscle mass include:
Reversing the decline in strength, bone density, and muscle mass with aging.
Maintenance of flexible joints.
Guide weight r n when combined with a healthy diet.

IMPORTANT CAUTION: Proper calorie intake and nutrion are importano maintain a healthy
body. Consultaphysician before undertaking any exercise or diet program.
BONE MASS – WHY MEASURE IT?
Regular exercise and a balanced diet can help maintain healthy bones. Like muscle, bone is a
living ssue that can respond to exercise by becoming stronger. For most people, bone mass
peaks in their thires. Then people begin to lose bone. Regular exercise can help prevenhat
loss.
Calcium and vitaminD(good sources include dairy products, green leafy vegetables, and fish)
contribute to healthy bones.
The bone mass readings given by this product are an esmaon ohe amount oone in your
body. Individuals with osteoporosis or low bone densies may not get accurate esmaons. If
you have any concern regarding your bones, please consult your doctor.
USING YOUR BODY FAT SCALE
In order to measure body fat and body mass index, you musirst enter your height, age and
gender (in athlete mode if applicable). The scale uses these parameters to calculate your
measurements. Screen prompts will lead you through programming your personal informaon
into the scale. The scale will then use the data to compute your measurement results.
NOTE: Athlete mode uses addionalsoware to calculate more accurate results for highly fit
individuals—persons who do 10 hours or more per week of aerobic acvity and have a resng
heart rate of 60 beats per minute. The scale is not calibrated for professional athletes or body
builders.
Bare feet are required for the analyzer to funcon properly:
Remove your shoes and socks before beginning the measurement. In order to gehe most
accurate and consistent reading, wipe your feet with a damp cloth, leaving them slightly damp
before stepping onto the scale.
REMINDER:The scale needs to be inializedaerbaeryinstallaon. The scale may also need
to be inialized ifis moved or bumped. At all other mes, you may directly proceed with the
following instrucons for programming your personal data into the scale. To inialize the
scale, simply press firmly on the scale plaorm. The display will show “0.0” and automacally
turn off. Your scale is now ready for use.

CARE AND MAINTENANCE
Clean exposed parts with a so, slightly damp cloth. To remove stains, use a mild soap.
Never use detergents, excess water, treated cloths, harsh cleaning agents, or sprays.
Do nommerse scale in water.
Treat your scale with care to ensure the best performance. It contains sensive
electronic parts. Avoid rough treatment. Do not jump on, drop or kick the scale.
Do not aemp o lubricate, disassemble, or open the scale casing as this will void
warranty.
Always weigh yourself on the same scale placed on the same floor surface.
Do not compare weight readings from one scale to another as some differences will
exist due to manufacturing tolerances.
Place your scale on a hard even floor to ensure the greatest accuracy and consistency.
Is recommended that you measure ahe same me ohe day, preferably early
evening before a meal, for the most consistent results.
Your scale rounds up or down to the nearesncrement.
If you weigh yourselwice and gewo different readings, your weight lies between the
two.
Do not dispose o aeries in fire. Baeries may explode or leak. Remove baeries from
the scale ifit will not be used for a long period.
TROUBLESHOOTING
1. You must have bare feeo take this measurement. In order to gehe most accurate and
consistent reading, wipe your feet with a damp cloth, leaving them slightly damp before
stepping on the scale. Repeat measurements again, maintaining maximum contact between
your feet and metal sensors.
2. The condion ohe skin on the boom of your feet can affec he reading. The natural
effects of aging or acvity can make the skin hard. Take the reading with clean and slightly
damp feeor best accuracy.

MORE QUESTIONS AND ANSWERS
The GoWISE USA Digital Body Fat Scale uses a measurement method known as Bioelectrical
Impedance Analysis (BIA). A minute electrical curren s sent through your feet and legs. This
current flows easily through the lean muscular , which has a high fluid content, but not
easily through fat. Therefore, by measuring your body’s impedance (i.e. its resistance to the
current), the y of the muscle can be determined, from which the y of fat can then
be
What is the value of the current passing through me when the measurement is taken? Is it
safe?
The electrical current is less than 1mA. You may not be able to feel it. Please note however that
this device should not be used by anyone with an internal electronic medical device, such as a
pacemaker, as a n against n to that device.
Replace the = Overload Warning. The maximum
weighing capacity of the scale has been
exceeded. Remove the weight
immediately; otherwise, permanent
damage to the scale will occur.

13
Why is the Athlete mode necessary?
It has been found that body fat esmaon using BIA could overesmate the percentage body
fat of adult elite athletes. The physiological variaon of athletes in bone density and level of
hydraon are two ohe reasons said to accounor the difference. The Athlete mode is
selectable only for adults 18 years of age or older.
Whas the definion of an Athlete?
The general consensus among researchers is that a quantave dimension could be used to
define an athlete. An athlete is considered to be a person who does 10 hours or more per week
of aerobic acvity and has a resng heart rate of 60 beats per minute. These individuals should
select Athlete Mode for the most accurate measurement results. This body fat scale is not
calibrated for professional athletes or body builders.
If I measure my body fat at a differenme during the day, it can vary quite considerably.
Which value is correct?
Your body fat percentage reading varies with body water content, and body water content
changes throughouhe day. There is no right or wrong me of day to take a reading; however,
for best results is suggested that you take measurements at a regular me of day, when you
consider your body to be normally hydrated. Avoid taking readings aer having a bath or sauna,
following extensive exercise, or within 1-2 hours of drinking in quanty or eang a meal.
My friend hasabody fat scale made by another manufacturer. When I used it, I get a
different body fat reading than when I use my GoWISE USA Body Fat Scale. Why is this?
Different body fat scales take measurements around different parts ohe body and use
differentmathemac algorithms to calculate the percentage oody fat. The best advice is not
to make comparisons from one device to another, buo use the same device each me to
monitor any change.
How do I interpret my body fat percentage readings?
Refer to the secon at beginning ohis manual, BODY FAT – WHAT DOES IT MEAN? The table is
a general guide to body fat readings (relave to your age and sex). Consult your physician for an
interpretaon thaakes your personal health history into consideraon.
Why are the body fat percentage ranges for men and women so different?
Women naturally carry a higher percentage offahan men, because the make-up ohe body
is different being geared towards pregnancy, breaseeding, etc.

14
Why should I avoid using the GoWISE USA Body Fat Scale while pregnant?
During pregnancy, a woman’s body composion changes considerably in order to supporhe
developing child. Under these circumstances, body fat percentage readings could be inaccurate
and misleading. PREGNANT WOMEN SHOULD CONSULT THE DOCTOR BEFORE USE.
