3. Useful information
What is BMI?
Body Mass Index (BMI) is a simple index of weight-for-height that is commonly used
to classify underweight, overweight and obesity in adults.
BMI uses the following simple formula to indicate the ratio between weight and
height of a person.
BMI = weight(kg) / height(m) / height (m)
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.
BMI Designation by the WHO
Less than 18.5 Underweight
18.5 or more and less than 25 Normal
25 or more and less than 30 Overweight
30 or more Obese
The above index refers to the values for obesity judgment proposed by WHO(World
Health Organization).
What is Body Fat Percentage?
The body fat content is shown as the amount of stored fat as a percentage of total
body weight. There is no generally accepted set value as this varies signicantly ac-
cording to gender (due to the different build) and age.
Body fat is vital for basic body functions. It’s protecting organs, cushioning joints,
regulating body temperature, storing vitamins and serves the body as energy storage.
As essential for women a minimum body fat proportion between 10% and 13%
and for men between 10% and 13% is requested with the exception of competitive
athletes.
Body fat is not a clear indicator for health. Too high body weight and a too high
body fat proportion are linked to the incidence of many civilization diseases such as
diabetes, cardiovascular diseases, etc.
Lack of movement and improper nutrition are often the prime course for these diseas-
es. There is an obvious direct relationship between overweight and lack of movement.

Body Fat Fluctuations in a Day
Hydration levels in the body may affect body fat readings. Readings are usually high-
est in the early waking hours, since the body tends to be dehydrated after a long
night's sleep. For the most accurate reading, a person should take a body fat percent-
age readings at a consistent time of day under consistent conditions.
Besides this basic cycle of uctuations in the daily body fat readings, variations may
be caused by hydration changes in the body due to eating, drinking, menstruation,
illness, exercising, and bathing. Daily body fat readings are unique to each person,
and depend upon one's lifestyle, job and activities.
