Information on Body Composition

Principle of body composition calculation
Body fat has low electric conductivity
The BF206-BT measures the body fat percentage by the Bioelectrical Impedance (BI) method. Muscles, blood
vessels and bones are body tissues with a high water content that conducts electricity easily. Body fat is tissue that
has little electric conductivity. The BF206-BT sends an extremely weak electrical current of 50 kHz and less than
500 μA through your body to determine the amount of fat tissue. This weak electrical current is not felt while operating
the BF206-BT.
In order for the scale to determine body composition, it uses the electrical impedance, along with your height,
weight, age and gender information to generate results based on OMRON's data of body composition.
Recommended measurement times
Understanding the normal changes in your body fat percentage can help you in preventing or reducing obesity.
Being aware of the times when the body fat percentages shift within your own daily schedule will assist you in
obtaining an accurate trending of your body fat. It is recommended to use this unit in the same environment and
daily circumstances. (See chart)

Avoid Taking Measurements Under the Following Conditions:
- Immediately after vigorous exercise, after a bath or sauna.
- After drinking alcohol or a large amount of water, after a meal (about 2 hours).
If a measurement is taken under these physical conditions, the calculated body composition may differ significantly
from the actual one because the water content in the body is changing.
What is BMI (Body Mass Index)?
BMI uses the following simple formula to indicate the ratio between weight and height of a person.
The OMRON BF206-BT uses the height information stored in your personal profile number or when entering
information in the Guest Mode to calculate your BMI classification.
If the fat level revealed by BMI is higher than the international standard, there is an increased likelihood of common
diseases. However, not all types of fat can be revealed by BMI.
After waking up
Before lunch and about 2 hours or
more after breakfast
In the afternoon about 2 hours or
more after lunch and before taking
a bath or eating dinner
Avoid measurement immediately
after eating or bathing.
Before going to bed and about 2
hours or more after dinner or bath
BMI = weight (kg) / height (m) / height (m)
