such as date and month, will not be
affected.
How the Body Fat Monitor
Works
When you step on the scale, a weight
measurement is taken. The GR101 can
also help you to automatically calculate
your Body mass index (BMI) and Body
Fat Percentage, two internationally
accepted indicators of health and obesity
levels.
Weight alone is not a good enough
indicator of health because it does not
differentiate between muscles, tissues,
bones, and fat. As such, when a person
loses weight, it may be a result of the
loss of muscles or body water but not fat.
In order to better understand your body
composition and current health level, both
the BMI and Body Fat Percentage should
be observed.
Neither the BMI nor the Body Fat
Percentage, taken individually, gives
the complete picture of your health. For
example, bodybuilders often have high
BMI (considered obese) but low Body
Fat Percentage (considered healthy).
The BMI, in this case, does not take
into account that the extra weight is
from muscles and water but not fat.
Conversely, a very thin person may have
low Body Fat Percentage (considered
healthy) but also lower-than-accepted
BMI (considered unhealthy). This means
that the person is still at risk health-wise,
despite the low Body Fat Percentage.
Consult your physician before you
begin a new diet or exercise program.
BODY MASS INDEX
What is Body Mass Index (BMI)?
Body mass index (BMI) is a widely used
international standard that measures
height to weight ratio to determine
obesity. BMI is expressed by the following
terms:
BMI = Body weight (kg)
[Body height (m)]2
The BMI is only a general indicator of
your health level. As such, accuracies
may vary depending on your body type
and composition. Consult your physician
to nd out more about your current health.
Refer to WEIGHT CONVERSION
TABLE to convert between weight units.
How to Interpret BMI
Use the resulting BMI value with the chart
below to determine your current level of
health:
Asians have a separate BMI range
due to their different body composition.

Consult with
your doctor
to develop a

*Asian
BMI:
30.0 or
greater
BMI should not be used as a
guideline for health risks for the following
groups:
Group Reason
Children
and
teenagers
BMI ranges are only
based on adult heights.
Athletes
and body-
builders
BMI does not
differentiate between
fat and muscle, thus
making it inaccurate
for persons with high
muscle volumes.
Pregnant
or nursing
women
This group generates
naturally high fat
reserves as part of the
pregnancy.

BODY FAT PERCENTAGE
What is Body Fat Percentage?
Body Fat Percentage is a measurement
of the total percentage of fat in your body.
For example, if you weigh 70 kg and your
Body Fat Percentage is 15%, then you
are retaining 10.5 kg of fat. The remaining
weight is composed of muscles, bones,
tissues, and water weight.
Among overweight people, it is excess fat
and not weight alone that carries health
risks. Since the body comprises elements
of varying densities, weight or BMI cannot
fully measure exactly how much excess
fat a person carries. For example, two
people of the same weight and BMI may
have big differences in body composition.
One may carry excess fat while the other
carry acceptable level of fat needed to
regulate the body. As such, a Body Fat
Percentage measurement is an effective
assessment of your current health level.
Essential fat is necessary for bodily
functions, since it helps to maintain body
temperature an insulate organs and
tissues.
How Body Fat is Measured
The GR101 uses the
method of Bioelectrical
Impedance Analysis
(BIA) to measure body
fat. This method is
completely safe, and is
widely used in the
medical eld. The
principle of BIA is as
follows: GR101 sends
a low, harmless
electrical signal through
your body that ows
freely through uids but
not fat. As such, the
machine measures the
opposition to the signal
and uses this to
calculate the body fat
percentage (along with
the person’s age,
height, and weight).

Body Fat
Standard
Reason
Very High Percent fat at this level
indicates the person
is seriously obese
to a degree that this
can have adverse
health consequences.
Maintaining this level of
fat for a long period of
time places the person at
risk of hypertension, heart
disease, and diabetes.
Consult your doctor on a
long-term weight loss and
exercise program.
High It is likely that the
person is obese. Careful
implementation and
monitoring of diet and
exercise is recommended.
Optimal This is the ideal level of
body fat for the average
person.
Low For athletes, this is a
desirable level of body
fat. For regular persons,
a regular diet should be
considered to improve
the balance of body
composition.
Very Low The level of body fat is too
low. Consult a physician
for advice.
How to Interpret Body Fat Level
Indication
In addition to displaying your Body Fat
Percentage, the GR101 provides a Body
Fat Level Indication on the LCD screen
to help you immediately gauge your level
of body fat without referring to the chart
above.

calculations, and computer
applications.

How Body Fat Percentage Fluctuates
It is recommended that you choose a
time slot to measure body fat and then
monitor it regularly at the same condition.
Ideally, body hydration level is most stable
during late afternoon, right before dinner.
Please note the many factors may alter
an individual’s body fat reading, including
alcohol consumption, taking a bath or
exercising, waking up, eating, fever and
illnesses.
BODY WATER
What is Body Water?
Total Body Water is the amount of water
retained in the body, and comprises
between 50%-70% of the total body
weight. Generally, men tend to have
higher water weight than woman due to a
greater amount of muscle. Athletes also
tend to have 5-8% more Total Body Water
