17. Information on Body Composition
Principle of body composition calculation
Body fat has low electric conductivity
HBF-222T 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 unit 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 unit.
In order for the scale to determine your 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
signicantly 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.
BMI = weight (kg) / height (m) / height (m)
The OMRON HBF-222T uses the height information stored in your personal number or when entering
information in the Guest Mode to calculate your BMI classication.
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.
