Obesity is such a medical condition of a body in which the body fat has reached to that extent that it will may have bad and adverse effect on health which are undesired and unlike. If a person's weight is at least 20-25% higher than it should be, then the person is considered obese. This all measurement is done by the Body Mass Index (BMI). The BMI measurement is a comparison between person's weight and height and sometimes it is of age also. If the BMI level is between 25 and 30 then person is considered over weight but if it is 30 or above then obese.

Obesity is not only a single problem for an obese person, but it also increases the likelihood of other diseases in which heart disease, certain type of cancers, diabetes, breathing problem and osteoarthritis are particular. Obesity is caused by some common activities, which have been adopted by a lot of people of this modern world, which includes our lazy routine, lack of physical exercise, dietary calories which means eating too many or imbalance calories, not enough sleep and obesity could also be genetically. There are also some cases in which obese people say that they eat little but they gain too much wait, this could be due to slow metabolism but most of the time obesity causes due to the over eating especially of junk food which makes the energy imbalance inside the body.

The obese people after coming to the obese stage starts looking for something which makes them quick weight loss. They try shortcuts for the sake of quick weight loss because they think that they want to be smart as soon as they got obese. With this thought they try too many different products claiming quick weight loss but they do not know that the primary treatment for them is the dieting and physical exercise. The anti-obesity or weight loss drugs should only be used when this all fails and if these also don't work then in this severe case either the surgery is performed or to reduce stomach volume the an intragastric balloon is used which is placed in the body.

Obesity, for no doubt, is a leading problem worldwide and it is cause of death globally. Only in the USA 34% adults are considered overweight and other 31% are obese.

The USA government should take steps for overcoming this situation by running useful campaigns for the fitness and providing enough infrastructure which can be used to weight loss of the obese and over weight people. There is also increase of obesity in other regions of the world like recently the higher increase is in the Asian countries.
