Obesity or overweight has a different meaning for everyone. For most women and men, obesity
means being overweight far exceeding the desired weight.
Sometimes we often have been confused with the understanding of obesity and overweight,
although the two terms have different understanding. Obesity is a condition where there is an
excessive accumulation of body fat, so that someone’s weight is far above normal and might be
harmful to health. Meanwhile overweight is a condition where someone’s weight exceeds the
normal weight.
Obesity definitions according to the doctors are as follow:• A condition in which body fat is in abundance• A chronic disease that can be treated
• An epidemic disease• A condition associated with other diseases and can reduce quality of life• Obesity treatment requires a very high treatment costs
Obesity occurs because there is an imbalance between the energy that comes in and comes out.
Body Mass Index (BMI) has been recognized as the most practical method in determining the
level of overweight and obesity in adults under the age of 70.

Currently estimated at more than 100 million worldwide people suffer from obesity, and this
number will remain continue to increase rapidly. If this situation continues, in the year of 2230
will be estimated that 100% of U.S population will become obese.
In many countries found that men tend to suffer from overweight (BMI 25-29.9), whereas women
tend to suffer from obesity (obese - BMI> 30).
With the advancement of developing countries, then overweight and obesity are also growing intoa global health problem that is very important. But because the data on these very rare, so the
handling on the development and overweight problems in developing countries become
obstructed, this might be due to geographical location and distribution of public social level.

Body Mass Index (BMI)The term “normal”, “overweight”, and “obese” can be different, each country and culture has itsown criteria, therefore, WHO set up a measurement / classification of obesity that does notdepend on cultural biases.
The most useful method and widely used to measure the level of obesity is a BMI (Body MassIndex), which is obtained by dividing weight (kg) by square of height (meters). BMI value obtaineddoes not depend on age and gender.
BMI limitations are can not be used for:
• Children who are in the growth period
• Pregnant women
• The person who is very muscular, for example athletes
BMI can be used to determine how likely a person can be exposed to the risk of certain diseases
caused by weight. Someone categorized as obese and needed treatment when having BMI
above 30, or in the other words the person excess 20% of body weight.
