Am I Obese?

Obesity is often measured using BMI, waist-circumference and/or waist-to-hip ratio.

Body Mass Index (BMI)


Body Mass Index (BMI) is a mathematical calculation involving height and weight. It does not take into account family history, gender, age or race.

BMI is calculated by dividing a person's body weight in kilograms by their height in meters squared (weight [kg] height [m]²) or by using the conversion with pounds (lbs) and inches (in) squared.

BMI can be a misleading number for very muscular people, and for pregnant or lactating women.

Waist Circumference

Waist circumference is another widely used measurement to determine abdominal fat content. An excess of abdominal fat, when out of proportion to total body fat, is considered a predictor of risk factors related to obesity. Men with a waist measurement exceeding 40 inches are considered at risk. Women are at risk with a waist measurement of 35 inches or greater. Waist-to-hip ratios are often predictors for increased risk of myocardial infarction, stroke, and premature death.
