Description

Obesity is due to positive energy balance, the intake of calories is more than expenditure of energy. It is a state in which there is generalised accumulation of excess adipose tissue in body leading to more than 20% of desirable weight. Overweight is a condition where the body weight is 10-20% greater than mean standard weight for age, height and sex.

Traditionally, a two-compartment model divides the body into fat mass, the fat from all body sources including the brain, skeleton, and adipose tissue, and fat-free mass(FFM), which includes water, protein, and mineral components.The proportions of FFM are relatively constant from person to person.
