INFORMATION ON BODY COMPOSITION
PRINCIPLES OF FULL BODY SENSING CALCULATIONS
What is Full Body Sensing?
Full Body Sensing provides a comprehensive understanding of your body composition to help you reach and/or maintain your fitness goals. Unlike other body composition monitors that rely on foot-to-foot measurements, Omron’s monitor measures the whole body (arm to foot) which provides a clinically-proven accurate profile.
How Omron calculates your body composition:
Omron’s algorithm focuses on the Bioelectrical Impedance Method as well as height, weight, age and gender.
Bioelectrical Impedance Method: The Omron Full Body Sensor Body Composition Monitor and Scale estimates the body fat percentage by the Bioelectrical Impedance Method. Muscles, blood, bones and body tissues with high water content conduct electricity easily. On the other hand, body fat does not store much water, therefore has little electric conductivity. The Omron Full Body Sensor Body Composition Monitor and Scale sends an extremely weak electrical current of 50 kHz and less than 500 µA through your body to determine the amount of water in each tissue. You will not notice or feel the electrical current.
The ratios of the water in your upper and lower body change throughout the day – as gravity pulls more water into your lower extremities. This means the electrical impedance of the body also varies – if more water is in your legs, other monitors such as foot-to-foot may show incorrect body fat readings. The Omron Full Body Sensor Body Composition Monitor and Scale takes measurements from both hands and feet – which reduces the influence water movement makes on your body composition results.

INFORMATION ON BODY COMPOSITION
BODY MASS INDEX
Body Mass Index (BMI) is a number calculated from a person’s weight and height. BMI is a reliable indicator of body fatness for people. BMI does not measure body fat directly, but research has shown that BMI correlates to direct measures of body fat. BMI is used as a screening tool to identify possible weight problems for adults.
BMI is calculated by using the following formula based on a ratio between your weight and height:
BMI = weight (lb) / height (inches) / height (inches) × 703

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) stored fat which is stocked for energy during physical 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.

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).

Subcutaneous Fat 
Visceral Fat 
Spine
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.

INFORMATION ON BODY COMPOSITION
RESTING METABOLISM
Regardless of your activity level, a minimum level of caloric intake is required to sustain the body’s everyday functions. Known as the resting metabolism, this indicates how many calories you need to ingest in order to provide enough energy for your body to function.
60-70% of daily energy use is for resting metabolism
The total amount of energy used by the body in a typical day is as follows:
Resting metabolism |
Energy required to maintain vital functions. |
|
Energy used for daily activities such as |
Daily activity metabolism |
commuting to work, household chores, |
|
hobbies etc. |
|
|
Diet-induced thermogenesis |
Energy emitted after eating a meal. |
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.

INFORMATION ON BODY COMPOSITION
SKELETAL MUSCLE
Skeletal muscle is the type of muscle that we can see and feel. When you work out to increase muscle mass, skeletal muscle is being exercised. Skeletal muscles attach to the skeleton and come in pairs -- one muscle to move the bone in one direction and another to move it back the other way. Increasing skeletal muscle will increase your body’s energy requirements. The more muscle you have, the more calories your body will burn. Building skeletal muscle can help prevent “rebound” weight gain. The maintenance and increase of skeletal muscle is closely linked to resting metabolism rate.

BODY AGE
Body age is based on your resting metabolism. Body age is calculated by using your weight, body fat percentage and skeletal muscle percentage to produce a guide to whether your body age is above or below the average for your actual age.

INFORMATION ON BODY COMPOSITION
WARNING
Contact your physician or healthcare provider before beginning a weight reduction or exercise program.
LONG-TERM PLANNING FOR SUCCESSFUL WEIGHT LOSS
There are lots of reasons for people to lose weight. To be healthier. To look better. To feel better. To have more energy.
No matter what the reason, successful weight loss and healthy weight management depend on sensible goals and expectations. If you set sensible goals for yourself, chances are you'll be more likely to meet them and have a better chance of keeping the weight off.
The foundation of a successful weight loss program remains a combination of a healthy diet and exercise customized for you. Simply reducing food intake to lose weight can lead to a decline in muscle mass and bone density. So even though your weight goes down, your resting metabolism is reduced making the body more prone to putting on fat. More skeletal muscle can prevent “rebound” weight gain.
The Omron Full Body Sensor Body Composition Monitor and Scale tracks your progress by monitoring weight, skeletal muscle, body fat, BMI and resting metabolism rate to help you reach your goals.
Here’s a comparison of losing weight quickly versus slowly:

Going to bed
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.
12
INFORMATION ON BODY COMPOSITION
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 for the following people:
•Elderly people
•People with a fever
•Body builders or highly trained athletes
•Persons undergoing dialysis
•Persons with osteoporosis who have very low bone density
•Persons with edema (swelling in the body)
•Children in growth stage
