WHAT IS OBESITY?

Obesity is a medical condition in which there is excess body fat. It is an energy imbalance disorder which results when your energy intake (the amount of calories you eat) is greater than your energy expenditure (the number of calories used by your metabolism, during physical activity and given out as body heat) over a long period of time.

Someone who is obese weighs at least 20% heavier than the ideal weight for their height.
