Body Mass Index

Obesity in the United States has been on the rise over the past 20 years or so. More than half of the states in the country have an obesity rate of over 25% of the state's population. The most accurate way to calculate or quantify obesity is through the Body Mass Index (BMI). BMI is calculated by dividing one's actual body weight by their height. Obesity is the result of an excess accumulation of fat beyond what the body naturally requires.
Morbid obesity is defined as having a body weight 100 pounds or greater over your ideal body weight and a BMI of 40+ or a BMI of 35 while experiencing other severe health issues such as diabetes or high blood pressure.

Please note: BMI does not distinguish between fat and muscle. A heavily muscled person could have a BMI in excess of 25 without having any increased health risks.
