Determining your body mass index
What is body mass index?
Determining how much you should weigh is not a simple matter of looking at a height-weight chart, but includes considering the amount of bone, muscle and fat in your body's composition.
The amount of fat is the critical measurement. A good indicator of how much fat you carry is the body mass index (BMI). Although it is not a perfect measure, it gives a fairly accurate assessment of how much of your body is composed of fat.
How can I tell if I'm overweight?
Use the tool on this page to calculate your BMI. Having a BMI higher than 24.9 may mean you are overweight. Note that these are approximate values, and they are intended to be used only as a rough guide.
If you are worried about your BMI or are trying to lose weight, talk to your primary care doctor. You may also wish to contact the Rush Center for Weight Loss and Lifestyle Medicine, which offers individualized weight loss and wellness programs for people of all ages. You may also contact the Rush Nutrition and Wellness Center or the Rush University Prevention Center. These programs offer nutrition counseling and help with making lifestyle changes.
Doctors at Rush offer bariatric surgery for some people who are morbidly obese (those with a BMI of at least 40, or a BMI of at least 35 plus an obesity-related disease such as diabetes or high blood pressure).
