Obesity causes

Many people think of obesity as an excess of total body weight whereas in fact, it is excess body weight as fat. Being overweight may also be defined in terms of how someone feels about him or herself, and psychological factors play an important role in obesity and weight loss.
Many people, particularly young women, think they are overweight when they may actually be underweight. For many people the optimum weight may not be as low as they would like.

Obesity causesAn ideal or optimum weight is difficult to define. A commonly used way to assess body weight is the body mass index (usually abbreviated as BMI). A person's BMI is calculated by dividing their weight in kilograms by the square of their height in meters. A BMI within the range 20 to 25 is considered normal. A value of between 25 and 30 is considered overweight and a value over 30 is defined as obese.

Factors contributing to obesity

Obesity causes are an enormously complex problem; there are various theories as to the cause. It is likely that there are several factors contributing to the weight problem of a particular person. For years the prevailing scientific view was that in order for weight loss to occur, energy (or calories) in needed to be less than the energy (or calories) out. This usually means either eating less or exercising more, and the best results seem to happen when someone does both.

However, new research suggests that weight management is more complicated than this and other factors contributing to obesity mean that a calorie is not the same for everyone.
Some people seem to have higher metabolic rates and burn up food more efficiently than others.
Obesity causes This may be due to a combination of genetic and psychological factors, gender, hormonal imbalances, poor liver function, food allergies and in some cases, medication use.
