Obesity related deaths are on the increase. Body mass index (BMI) = weight in kg divided by the square of height in meters.

BMI for adults:

Normal BMI: 18 – 25
Overweight: 25 – 30
Obesity: BMI 30 – 40
Morbid obesity: BMI > 40

To avoid obesity, ban eating in front of television. Food should be served only in the dining room. Encourage healthy eating habits and outdoor games. Bariatric surgery is only for the morbidly obese with comorbidity. On the preventive aspect, both low birth weight and high birth weight are to be prevented as they are fore runners of obesity. Obesity is the after effect of easy availability of inexpensive food and sedentary jobs.
