What do you mean by Obesity?

Obesity, also called corpulence or fatness, is a condition characterised by abnormal or excessive fat accumulation to an extent that it may have a negative effect on health.

It is usually caused by the consumption of more calories than the body can use.

If one consumes high amounts of energy by eating food particularly rich in fat and sugars, but do not burn it off through exercise and physical activity, then much of the surplus energy will be stored by the body as fat and results in Obesity.
