BMI Calculator for Adults
The term BMI is often used when discussing the obesity epidemic, but what is BMI?
BMI stands for Body Mass Index. It is a number that shows body weight adjusted for height. BMI can be calculated with simple math using inches and pounds. For adults aged 20 years or older, BMI falls into one of these categories: underweight, normal, overweight, or obese. Click on the link located below the table to find out how to calculate BMI for your children or teens.
|18.5 - 24.9||Normal|
|25.0 - 29.9||Overweight|
|30.0 and Above||Obese|
BMI correlates with body fat. The relation between fatness and BMI differs with age and gender. For example, women are more likely to have a higher percent of body fat than men for the same BMI. On average, older people may have more body fat than younger adults with the same BMI. Highly trained athletes may have a high BMI because of increased muscularity rather than increased body fatness.
So you have calculated your BMI and found which weight category your BMI matches. What does this all mean?
BMI is not the only indicator of health risk.
BMI is just one of many factors related to developing a chronic disease (such as heart disease, cancer, or diabetes). Other factors that may be important to look at when assessing your risk for chronic disease include:
- Waist Circumference
- Physical Inactivity
- Blood Pressure
- Blood Sugar Level
- Family History of Disease
All persons who are obese or overweight should try not to gain additional weight. In addition, those who are obese or who are overweight with other risk factors should consider losing weight. Even a small weight loss (just 10% of your current weight) may help to lower the risk of disease. A complete health assessment by a physician is the best way to decide the right steps for you.
Remember, your BMI is only one piece of your health profile. It is important to talk with your doctor about other measures and risk factors. (e.g., waist circumference, smoking, physical activity level, and diet.)
Physical activity and good nutrition are key factors in leading a healthy lifestyle and reducing risk for disease.
