Calculating Your BMI

Healthcare professionals around the world often use Body Mass Index (BMI) when determining whether patients are underweight, healthy weight, overweight or clinically obese. People who are clinically obese have a greater risk of developing diabetes, stroke, some cancer, and cardiovascular diseases.

BMI has its drawbacks however. It does not take into account the patient's body fat content versus lean tissue (muscle) content. A 6 feet 2 inch athlete may have a higher BMI than a couch potato of the same height - but the couch potato may be overweight while the athlete is definitely not.

Your BMI is based on your height and weight. It's one way to see if you're at a healthy weight.

Underweight: Your BMI is less than 18.5

Healthy Weight: Your BMI is 18.5 to 24.9

Overweight: Your BMI is 25 to 29.9

Obese: Your BMI is 30 or higher
