What is my Body Mass Index and what does it mean?
Guidelines on the identification, evaluation, and treatment of overweight and obesity in adults released by the National Heart, Lung, and Blood Institute (NHLBI), in cooperation with the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), use the following definitions:
- A BMI of less than 18.5 is considered underweight.
- A BMI of 18.5 to 24.9 is considered healthy.
- A BMI of 25 to 29.9 is considered overweight.
- A BMI of 30 or more is considered obese.
Because BMI does not show the difference between fat and muscle, it does not always accurately predict when weight could lead to health problems. For example, someone with a lot of muscle (such as a body builder) may have a BMI in the unhealthy range, but still be healthy and have little risk of developing diabetes or having a heart attack.
BMI also may not accurately reflect body fatness in people who are very short (under 5 feet) and in older people, who tend to lose muscle mass as they age. But for most people, BMI is a reliable way to tell if your weight is putting your health at risk.
