BMI is a measure of a person's weight. The BMI formula is applicable to both men and women and is only applicable to adults (over 18 years old), not applicable to pregnant women, athletes, the elderly and varies between countries.

BMI helps you determine whether your body is currently obese or malnourished and to what extent. BMI is calculated based on height and weight data. Once you know your BMI, you can plan to lose weight or supplement appropriate nutrition.
