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 field. The
principle of BIA is as
follows: GR101 sends
a low, harmless
electrical signal through
your body that flows
freely through fluids 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).
How to Interpret Body Fat Levels
Use the resulting Body Fat Percentage
value with the chart below to determine
your current level of health:

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.
