HOW DOES THE GoWISE USA BODY FAT SCALE WORK?
This GoWISE USAR body fat scale uses Bio Impedance Analysis (BIA) technology which passes an
electrical current through the body to estimate 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 platform 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 of this analyzer might be different than 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 information provided by this device is NOT meant to treat, cure, or p revent any
disease or illness. This device should NOT be used by anyone who is acutely or chronically ill,
suffering from a disease, or taking medications that affect your water levels. The accuracy of
readings for these patients has not been verified. Specific medical advice should be obtained
from a physician.
CAUTION: This scale is NOT intended for use by pregnant women or children under the age of 18.
It should also NOT be used by anyone with an implanted medical device (such as a pacemaker,
metal plates or screws; or contraceptive devices). If in doubt, contact your physician.
This analyzer will work accurately as a scale for anyone, within the specifications and warnings

BODY MASS INDEX (BMI) –WHY MEASURE IT?
Maintaining proper weighti s essential to healthy living. Obesity has been linked to a higher risk
ofh eart disease, diabetes, and some forms of cancer. The Body Mass Index (BMI) is calculated
based on a person’s weight and height, and is the most widely accepted measurement of
weight according to health professionals. Use the chart below to determine your own BMI by
matching your heighti n the lefthand column with your weighti n the center. Anyone, male or
female, with a BMI of 25-29 is considered overweight and a body mass index of 30 is considered
obese. Remember to eat right and exercise.

BODY FAT –WHAT DOES IT MEAN?
Human body is made up of, among other things, a percentage offat. Body fati s an important
component of a healthy and functioning 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 little body fat can cause damage to your health. Iti s difficult
to gauge how much body fat we have in our bodies simply by looking at ourselves in the mirror.
This is why iti s importantt o measure and monitor your body fat percentage. Body fat
percentage gives you a better measurement offitness than weight alone; the composition of
your weight loss could mean you are losing muscle mass rather than fat—you could still have a
high percentage offat even when a weight-only scale indicates ‘normal weight’.
1. Ideal body fat contenti s NOT the same for all people. Age, Sex, and heredity are
variables in this measurement. The table thatf ollows is a general guide. Consult your
physician to determine whati s mosti deal for you.

2. Iti s recommended to measure body fat and weight daily att he same time.
3. Use this product without clothing for best accuracy. Clothes can vary in weight and
affectt he percentage calculation.
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 mosti mportant component ofb ody weight. It represents over half of
your total weight and almostt 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 function properly ift hey have
enough water. Water also plays a vital parti n regulating the body’s temperature balance,
particularly through perspiration. The combination of your weight and fat measurement could
appear to be ‘normal’, but your body hydration level could be insufficientf 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 information you entered (Height, Age, Gender). It
then automatically calculates your body fat percentage. Your level ofh ydration (water content)

5
varies throughout the day and affects your impedance measurement. If you are dehydrated,
there is a greater chance for fluctuation in the body fat percentage displayed by this scale than
when you are fully hydrated.
For best results, choose a consistent time to use this analyzer, such as in the morning. By
establishing the pattern of your body’s fluctuation over a period of one month, you can
determine your average level of body fat. Women will have more fluctuation 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 several hours before taking a body fat reading when: Drinking coffee or alcohol,
taking diuretic medications, or exercising. These all affect your level of hydration and the
accuracy of this scale.
A guide to normal healthy range of total body water (TBW) percentage for MEN:
BF %Range Optimal TBW %Range
4 to 14% 70 to 63%
15 to 21% 63 to 57%
22 to 24% 57 to 55%
25 and over 55 to 37%
A guide to normal healthy range of total body water (TBW) percentage for WOMEN:
4 to 20% 70 to 58%
21 to 29% 58 to 52%
30 to 32% 52 to 49%
33 and over 49 to 37%
Body water measurement results are influenced by the proportion of body fat and muscle. If
the proportion of body fat is high, or the proportion 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 fluctuations can be
normal, we suggest that you chart your progress over time, 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 inactive/sedentary lifestyle can cause loss
of lean body mass while body fat increases. It’s also important to know your muscle mass

6
percent during weight reduction. At rest, the body burns approximately 110 additional 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 reduction when combined with a healthy diet.
IMPORTANT CAUTION: Proper calorie intake and nutrition are importantt o maintain a healthy
body. Consult a physician 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 tissue that can respond to exercise by becoming stronger. For most people, bone mass
peaks in their thirties. Then people begin to lose bone. Regular exercise can help preventt hat
loss.
Calcium and vitamin D (good sources include dairy products, green leafy vegetables, and fish)
contribute to healthy bones.
The bone mass readings given by this product are an estimation oft he amount ofb one in your
body. Individuals with osteoporosis or low bone densities may not get accurate estimations. If
you have any concern regarding your bones, please consult your doctor.

USING YOUR BODY FAT SCALE
Normal Hi gh
In order to measure body fat and body mass index, you must first 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 information
into the scale. The scale will then use the data to compute your measurement results.
NOTE: Athlete mode uses additional software to calculate more accurate results for highly fit
individuals—persons who do 10 hours or more per week of aerobic activity and have a resting
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 function properly:
Remove your shoes and socks before beginning the measurement. In order to get themost
accurate and consistent reading, wipe your feet with a damp cloth, leaving them slightly damp
before stepping onto the scale.

MORE QUESTIONS AND ANSWERS
The GoWISE USA Digital Body Fat Scale uses a measurement method known as Bioelectrical
Impedance Analysis (BIA). A minute electrical currenti s sentt hrough your feet and legs. This
currentf lows easily through the lean muscular tissue, 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 quantity oft he muscle can be determined, from which the quantity offat can then
be estimated.
What is the value o f
safe?
the current passing through me when the measurementi s taken? Is it
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 precaution against disruption to that device.
Why is the Athlete mode necessary?
It has been found that body fat estimation using BIA could overestimate the percentage body
fat of adult elite athletes. The physiological variation of athletes in bone density and level of
hydration are two of the reasons said to account for the difference. The Athlete mode is
selectable only for adults 18 years of age or older.
What is the definition of an Athlete?
The general consensus among researchers is that a quantitative 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 activity and has a resting 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 different time 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 throughout the day. There is no right or wrong time of day to take a reading; however,
for best results it is suggested that you take measurements at a regular time of day, when you
consider your body to be normally hydrated. Avoid taking readings after having a bath or sauna,
following extensive exercise, or within 1‐2 hours of drinking in quantity or eating a meal.
My friend has a body 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 of the body and use
different mathematic algorithms to calculate the percentage of body fat. The best advice is not
to make comparisons from one device to another, but to use the same device each time to
monitor any change.

How do I interpret my body fat percentage readings?
Refer to the section at beginning of this manual, BODY FAT –WHAT DOES IT MEAN? The table is
a general guide to body fat readings (relative to your age and sex). Consult your physician for an
interpretation that takes your personal health history into consideration.
Why are the body fat percentage ranges for men and women so different?
Women naturally carry a higher percentage of fat than men, because the make‐up of the body
is different being geared towards pregnancy, breastfeeding, etc.
Why should I avoid using the GoWISE USA Body Fat Scale while pregnant?
During pregnancy, a woman’s body composition changes considerably in order to support the
developing child. Under these circumstances, body fat percentage readings could be inaccurate
and misleading. PREGNANT WOMEN SHOULD CONSULT THE DOCTOR BEFORE USE.
