Body Mass Index

Body mass index (BMI) is a person’s weight in kilograms divided by the square of height in meters. BMI is an inexpensive and easy screening method for weight category—underweight, healthy weight, overweight, and obesity.

• BMI may not be the best indicator for risks related to obesity in certain ethnic populations, including Indians. Some individuals who look thin and have fat located around their stomach may still be at increased risk. It is important to take into account your central adiposity, measured by factors such as waist-hip circumference ratio.
• It may overestimate body fat in athletes and others who have a muscular build.
• It may underestimate body fat in older persons and others who have lost muscle.

Therefore it is wiser to consult your doctor for proper interpretation of your BMI.
