Information on Body Composition
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
The 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.
What is Visceral Fat Level?
Visceral fat = fat surrounding 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 diseases such as hyperlipidemia and
diabetes, which impairs the ability of insulin to transfer energy from the bloodstream
and using it in cells. In order to prevent or improve conditions of common diseases,
it is important to try and reduce visceral fat levels to an acceptable level. People
with high visceral fat levels tend to have large stomachs. However, this is not
always the case and high visceral fat levels can lead to metabolically obese.
Metabolically obese (visceral obesity with normal weight) represents fat levels that
are higher than average, even if a person's weight is at or below the standard for
their height.
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 is not displayed in
this unit, but is included in the body fat percentage.
What is Skeletal Muscle?
Muscle is divided into two types, muscle in internal organs, such as the heart, and skeletal muscle attached to
bones that is used to move the body. Skeletal muscle can be increased through exercise and other activity.
Increasing the ratio of skeletal muscle means that body can burn energy more easily, which means that it is less
likely to turn to fat, and makes it easier to lead an energetic lifestyle.
What is 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.
The reason calculated results may differ from actual body fat percentage
The body fat percentage measured by this unit may significantly differ from the actual body fat percentage in
the following situations:
Elderly people (over 81 years old) / People with a fever / Body builders or highly trained athletes / Patients
undergoing dialysis / Patients with osteoporosis who have very low bone density / Pregnant women / People
with swelling
These differences may be related to changing ratios of body fluid and/or body composition.
