Everybody is concerned about their weight. But what is the basis for determining your
ideal weight?
The key is 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.
The Ideal BMI is 22
Maintaining an ideal weight can help prevent obesity or weight loss and other
diseases, and lead a longer life. The ideal weight for a BMI of 22 is calculated as
follows.
Ideal Weight (kg) = 22 × height (m) × height (m)
Example: For a person 1.55 m tall...
22 × 1.55 × 1.55 = 52.855 -> Approx 52.9 kg
However, this method of ideal weight calculation may not be applicable for
professional athletes and body builders, who have higher muscles ratio in their
bodies.
The OMRON Body composition monitor uses the Height information stored in
your personal profile number to calculate your BMI.
BMI = weight (kg) / height (m) / height (m)
BMI & IDEAL WEIGHT
The above-mentioned indices refer to the values for obesity judgment proposed by the WHO, the World Health
Organization.
Interpreting the BMI Result

BODY FAT
Body fat serves a vital role in storing energy and protecting internal organs. We carry
two types of fat in our bodies: 1) essential fat which is stored in small amounts to
protect the body and 2) adipose tissue (stored fat) provides cushion and insulation
to internal organs, covers the nerves, moves vitamins throughout the body and is the
largest reserve of stored energy available for activity. While too much body fat may be
unhealthy, having too little fat can be just as unhealthy. Also, the distribution of body
fat in men and women is different, so the basis for classifying the body fat percentage
is different between the genders.
What is Body Fat Percentage?
Body fat percentage refers to the amount of body fat mass in regards to the total body
weight expressed as a percentage.
Body fat percentage (%) = {Body fat mass (kg) / Body weight (kg)} × 100
Our device uses BI method to estimate your body fat percentage.
Depending on where fat is distributed in the body, it is classified as visceral fat or
subcutaneous fat.

INFORMATION ON BODY COMPOSITION
VISCERAL FAT
Visceral fat is found in the abdomen and surrounding vital organs. It is different from
fat found directly underneath the skin, which is referred to as subcutaneous fat.
Visceral fat can go largely unnoticed because it's not visible to the naked eye. One
way visceral fat can be seen is through Magnetic Resonance Imaging (MRI).
Interpreting the Visceral Fat Level Result
* The data referenced by OMRON Healthcare.
NOTE: Visceral fat levels are relative and not absolute values.
What is Subcutaneous fat?
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 other complications.
Subcutaneous Fat
Visceral Fat
Spine
MRI Cross Section at the Navel Level
Too much visceral fat is thought to be closely linked to increased levels of fat in the
bloodstream, which may lead to conditions such as high cholesterol, heart disease
and type 2 diabetes. In order to prevent or improve these conditions, it is important to
try to reduce the amount of visceral fat levels to an acceptable level.
Visceral Fat Level Level Classification
0.5 - 9.5 0 (Normal)
10.0 - 14.5 + (High)
15.0 - 30.0 ++ (Very High)

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
Resting metabolism Energy required to maintain vital functions.
Daily activity metabolism Energy used for daily activities such as
commuting to work, household chores,
hobbies etc.
Diet-induced thermogenesis Energy emitted after eating a meal.
The total amount of energy used by the body in a typical day is as follows:
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 caloric intake exceeds the amount of energy required for these activities,
the additional calories can be stored as fat.

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.
What is skeletal muscle ratio … Refers to the amount of skeletal muscle mass in regards to the total body
weight expressed as a percentage.
Skeletal muscle ratio (%) = {Skeletal muscle mass (kg) / Body weight (kg)} × 100
This product uses BI (Bioelectrical Impedance) to calculate your skeletal muscle mass.
Keep skeletal muscle and strengthen it to make corporeity not easily become fat.
This product's feature is the measurement of skeletal muscle ratio.
If you strengthened skeletal muscle and improved basal metabolism, you can throw your energy fleetly and not
easily get fat. and muscle will be strengthened to enjoy active life.

BODY AGE
Body age is based on your resting metabolism. Body age is calculated by using your
weight and body fat percentage to produce a guide to judge whether your body age
is above or below the average for your actual age. To know your body age is useful to
improve your health condition.
Body age varies according to Body composition and resting
metabolism, even if your height and weight is the same
The figures below shows some examples of body age.
The example on the left has a body age of 30, or average body composition for the
actual age.
The example in the middle has a lower body fat percentage than average and higher
resting metabolism, which results in a body age of 25 that is younger than the actual
age.
The example on the right has a higher body fat percentage than average and lower
resting metabolism, which results in a body age of 35 that is older than the actual
age.

Feature of body composition monitor
Measuring principle of body composition monitor
Calculate body fat in accordance with resistance value.
KaradaScan measures body resistance by using weak currency flowing through both hands and
both feet (RI method*).
* BI method (Bioelectrical Impedance/ biological resistance method) .
Tissues with more water content in human body tend to conduct electricity (such as muscle and
vein) easily. Fat tissue almost conducts no electricity. The body feature is used to calculate rate of fat
tissue and non-fat tissue.
Currency flowing through human body is very weak (50 kHz, 500μA) , which is not stimulant and is
very safe to human body.
In order to obtain body fat and other data from resistance between both hands and both feet,
The five items, i.e., (1) resistance value, (2) height, (3) weight, (4) age and (5) gender are required,
which are obtained in accordance with basic human data collected by the company independently.
Is the method of whole body measuring, which is not subject
to daily variation.
1 Water content in our body tends to accumulate in our leg during day. That's why we usually feel
dropsy at the feet at dusk or in the evening.
In the morning and dusk, body resistance distribution will change, as water proportion in upper
body and lower body changes.
KaradaScan measures whole body resistance by using electrode of both hands and both feet.
Therefore, it is less subject to variation of water content distribution in human body.
Basic data used to establish body composition formula,
Collect by using measuring method and measuring device
most suitable for various body compositions.
Body fat: weighing method in water (Submerge your head into water pool and exhaust all air in
your lung before measuring body weight. The method to calculate body fat in accordance
with body density is based on Archimedes principle. )
Resting metabolism: breath analyzing device (used to analyze air composition in breath). It
can be used to measure oxygen consumption of breath at quiet time to calculate resting
metabolism.)
Subcutaneous fat and skeletal muscle: DXA (Dual Energy X-Ray Absorptiometry) method
(measuring body composition at different parts by quantifying bone quantity and body
composition of 2 kinds of X rays with different wave length without the need of resolving body
to calculate weight.)
MRI (Magnetic Resonance Imaging System) (large number of hydrogen atomic nucleus
contained in human body resonate with magnetic field and electric wave. Image hydrogen
atomic nucleus and nuclear magnetic resonance to calculate human body composition.)

Q&A of Body Composition Monitor
■ What is correct weight reduction?
If you lose weight by going on a diet instead of taking exercise and neglect nutrition balance,
even if your weight is reduced, resting metabolism will decrease as muscle (skeletal muscle)
decreases and you are more likely to become fatter.
In order to avoid reversing,
You should build up non-fat physique by increasing skeletal
muscle and improving resting metabolism.
Extreme weight losing is most likely to reverse your body weight. When body
weight is reversed, visceral fat is more likely to accumulate in human body than
subcutaneous fat. Visceral fat is the major cause of life habit related disease. It is
body weight reversion that leads to visceral fat obesity.
■ Those who is concerned about their health...
Pay attention to visceral fat level ( page 32)
■ If you want to be a person not tending to be fat...
You should lay emphasis on resting metabolism ( page 33)
For example, in case of weight reduction by 10 kg, Internal change of body is different.
Reduced fat: 3kg
Reduced fat: 9kg
Reduced non-fat: 7kg
