BMI- Body Mass Index

The most common measure of obesity is the body mass index or BMI. A person is considered overweight if his or her BMI is between 25 and 29.9; a person is considered obese if his or her BMI is over 30."Morbid obesity" has a BMI of 40 or higher, or is sufficiently overweight to severely interfere with health or normal function.The calculation of body mass index (BMI) has also been used in the definition of obesity.

 The body mass index (BMI) equals a person's weight in kilograms (kg) divided by their height in meters (m) squared.

Since BMI describes body weight relative to height, it is strongly correlated with total body fat content in adults. "Obesity" is defined as a BMI of 30 and above.The BMI is a statistical measurement derived from your height and weight. Although it is considered to be a useful way to estimate healthy body weight, it does not measure the percentage of body fat.
