Obesity can be defined as the generalized accumulation of excess fat in the body. We come across obese in every ten people and according to many surveys the figure is increasing every year. At the same time many people are trying to keep them fit by following dietary guidelines for weight lose to achieve the ideal body weight. The desirable body weight is dependent on body frame size of a person. For example the desirable body weight is different for a marathon runner and a wrestler. So, body mass index (BMI) is the easy way to express obesity.
