Difference between obesity and being overweight: Obesity is a condition of excess accumulation of fat in the body. It is different from being overweight as that weight may come from muscle, bone, fat, etc. Overweight and obesity are defined as abnormal or excessive fat accumulation that may impair health. Body mass index (BMI) is a simple index of weight-for-height that is commonly used to classify overweight and obesity in adults. It is defined as a person’s weight in kilograms divided by the square of his height in meters (kg/m2).
For adults, WHO defines overweight and obesity as:
- overweight is a BMI greater than or equal to 25; and
- obesity is a BMI greater than or equal to 30.
For children under 5 years of age:
- overweight is weight-for-height greater than 2 standard deviations above WHO Child Growth Standards median; and
- obesity is weight-for-height greater than 3 standard deviations above the WHO Child Growth Standards median.
For children aged between 5–19 years:
- overweight is BMI-for-age greater than 1 standard deviation above the WHO Growth Reference median; and
- obesity is greater than 2 standard deviations above the WHO Growth Reference median.
Obesity is a complex disorder involving an excessive amount of body fat. It increases the risk of diseases and health problems, such as cardiac problems, diabetes and high blood pressure. Even discreet weight loss can expand or avoid the health problems associated with obesity.

India has the third-highest number of obese and overweight people (11 % of adolescents, and 20 % of all adults) after US and China, a recent study mapping global malnutrition trends has revealed.
