BODY MASS INDEX AND IDEAL WEIGHT
Everybody is concerned about their weight. But what is the basis for determining your ideal weight?
The key is Body Mass Index.
How to Calculate BMI
BMI is short for Body Mass Index. This index uses the following simple formula to indicate the ratio
between weight and height of a person.
×
BMI = weight (lb) / height (inch) / height (inch) 703
The OMRON HBF-500 uses the height information stored in your Personal Profile Number to
calculate your BMI classification.
Let’s look at an example

Let’s look at an example
When most people think of body fat, they have a
negative image of it. However, body fat serves a
vital role in storing energy, protecting internal
organs, etc. While too much body fat may be
unhealthy, having too little may also be unhealthy.
The distribution of body fat in men and women is
different, so the basis of classifying the body fat
percentage for males is different than for females.

USEFUL INFORMATION
VISCERAL FAT
Body fat is classified as subcutaneous fat or visceral fat, depending on where it is located in the body.
Visceral fat = fat surrounding the internal organs
Too much visceral fat is thought to be closely linked to increased levels of fat in the bloodstream, which can lead to
common conditions such as high cholesterol, cardiovascular disease and diabetes. In order to prevent or improve
conditions of these common diseases, it is important to try and reduce the visceral fat levels to an acceptable level.
Subcutaneous fat = fat below the skin
Subcutaneous fat not only accumulates around the stomach but also around the upper arms, hips and thighs, and can
cause a distortion of the body’s proportions. Although not directly linked to increased risk of disease, it is thought to
increase pressure on the heart and may be associated with other complications. Subcutaneous fat is not displayed
separately in this unit, but is included in the body fat percentage.

RESTING METABOLISM & SKELETAL MUSCLE
Skeletal muscle is muscle that is connected to bone and used to move parts of the body.
The maintenance and increase of this skeletal muscle is closely linked to resting metabolism.
What is resting metabolism?
Regardless of your activity level, a minimum level of energy is required to sustain the body's everyday
functions. Resting metabolism, the amount of calories needed to supply the body with the minimum
level of energy, differs between individuals depending on variables such as age, weight, body
composition, and energy expenditure.
60-70% of daily energy use is for
resting metabolism
Let’s look at an example
The total amount of energy burned by the body in
a typical day is as follows.
Energy required to
Resting metabolism
maintain vital functions.
Energy used for daily
activities such as
Daily activity metabolism commuting to work,
household chores,
RESTING METABOLISM
hobbies, etc.
Diet-induced
thermogenesis
Energy emitted after
eating a meal.
Example of display:
• Resting Metabolism:
1186 kcal
The ratio of these is 60%-70% for resting
metabolism, 20%-30% for daily activity, and 10%
for diet induced thermogenesis. This means that
resting metabolism accounts for most of our daily
energy consumption.
If our daily food intake exceeds the amount of
energy required for these activities, the additional
energy is stored as fat.

USEFUL INFORMATION
What is skeletal muscle?
Muscle is divided into two types, muscle in internal organs, such as the heart, and muscle attached to
bones that is used to move the body. Skeletal muscle can be increased through exercise and other
activity.
Resting metabolism reduces as we get older
Resting metabolism level peaks in the late teenage years and then gradually reduces over the years.
This leads to reductions in the body’s functions as we get older and in particular, it is one of the main
causes for muscle reduction as we get older.
Even when not being used to move parts of the body, muscles burn energy throughout the day to
generate heat for the body which is part of the resting metabolism. As the amount of muscle decreases,
so does the amount of energy burned. If people continue to eat the same amount of food as when they
are younger, then they develop “middle-age spread.”
In order to avoid this, it is important to know your resting metabolism and maintain muscles through
exercise.

USEFUL INFORMATION
LONG-TERM PLANNING FOR SUCCESSFUL WEIGHT LOSS
Ignoring a balanced diet and simply reducing food intake to lose weight can lead to a decline in muscle
and bone. So even though your weight goes down, your resting metabolism is reduced making the
body more prone to putting on fat.

*This is an extreme case of the effect.
Repeated dieting and regaining weight leads to increased visceral fat levels
It is easy to regain weight after sudden diets. This regained weight tends to appear as visceral fat rather
then subcutaneous fat. Increased visceral fat levels are thought to increase the likelihood of common
diseases. Repeated dieting and subsequent regaining of weight may lead to increased visceral fat levels.

USEFUL INFORMATION
PRINCIPLE OF BODY COMPOSITION CALCULATION
What is the Bioelectrical Impedance Method?
The HBF-500 estimates the body fat percentage by the Bioelectrical Impedance (BI) method.
Muscles, blood vessels and bones are body tissues with high water content that conduct electricity
easily. Body fat is tissue that has little electric conductivity. The HBF-500 sends an extremely weak
electrical current of 50 kHz and less than 500 µA through your body to determine the amount of each
tissue. This weak electrical current is not felt while operating the HBF-500.
How to Calculate the Body Composition
The following methods have been the established method for accurate evaluation of body composition.
Body Fat Percentage: This is based on the DXA (Dual Energy X-Ray Absorptiometry) method,
which uses two different x-rays to make a quantitative assessment of the amount of fat in the body.
Resting Metabolism: This is based on exhalation analysis, where the composition of exhaled air is
analyzed. This makes it possible to calculate the resting metabolism by measuring the consumption of
oxygen in exhaled air.
Visceral Fat Level: This is based on MRI (Magnetic Resonance Imaging) analysis, which uses
nuclear magnetic resonance to make non-intrusive images of the body. This makes it possible to
calculate the area of visceral fat at cross section of abdomen.
Skeletal Muscle Percentage: This is based on MRI (Magnetic Resonance Imaging) analysis,
which uses nuclear magnetic resonance to make non-intrusive images of the body. This makes it
possible to calculate the amount of skeletal muscle in the body.
Omron has developed a formula referring to the above methods. The body composition is calculated
by a formula that includes five factors: electrical resistance, height, weight, age and gender.
Measures the whole body to avoid the influence of fluctuations
The ratios of the water in your upper body and lower body may change through the day. This means
that the electrical impedance of the body also varies. Since the HBF-500 uses electrodes for both the
hands and feet to take measurements, it can reduce the influence of water movement on measurement
results.

USEFUL INFORMATION
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. Reference the chart below:
Avoid Taking Measurements Under the Following Conditions
If a measurement is taken under the following physical conditions, the calculated body composition
may differ significantly from the actual one because the water content in the body is changing:
Immediately after vigorous exercise, after a bath or sauna, after drinking alcohol, after drinking a large
amount of water or after a meal (1 to 2 hours).

USEFUL INFORMATION
The reason calculated results may differ from actual body fat percentage
There are certain conditions when significant differences may occur between the estimated and the
actual body fat values. These differences may be related to changing ratios of body fluid and/or body
composition.
The body fat percentage measured by this monitor may significantly differ from the actual body fat
percentage in the following situations:
• Elderly people
• People with a fever
• Body builders or highly trained athletes
• Persons undergoing dialysis
• Persons with osteoporosis who have very low bone density
• Pregnant women
• Post-menopausal women
• Persons with edema (Swelling in the body)
• Children in growth stage
