What is the meaning of Obesity?

Obesity is a condition resulting from accumulation of excess body fat. The fat deposition takes place because over a period of time, people consume diets which provided much more energy than they were able to expend for their metabolism, physical activity and growth. The prevalence of obesity in developing countries has increased. This is because communities have emerged from a life style of subsistence towards a life style of affluence. In all over the world, there has been an increased migration of the rural population to urban areas. This shift also has been a contributing factor to life style changes including significant reduction in physical activity leading to changes in weight.
