BMI
Information
A good way to assess your weight is to calculate your body mass index (BMI). Your BMI estimates whether you are at a healthy weight. Being overweight puts strain on your heart and can lead to serious health problems. These problems include type 2 diabetes, heart disease, high blood pressure, sleep apnea, varicose veins, and other chronic conditions. More than 300,000 lives could be saved in the United States each year if everyone maintained a healthy weight!
HOW TO DETERMINE YOUR BMI
Your BMI estimates how much you should weigh based on your height. Here are the steps to calculate it:
- Multiply your weight in pounds by 703.
- Divide that answer by your height in inches.
- Divide that answer by your height in inches again.
For example, a woman who weighs 270 pounds and is 68 inches tall has a BMI of 41.0.
Use the chart below to see what category you fall into, and whether you need to be concerned about your weight.
BMI |
CATEGORY |
Below 18.5 |
Underweight |
18.5 - 24.9 |
Healthy |
25.0 - 29.9 |
Overweight |
30.0 - 39.9 |
Obese |
Over 40 |
Morbidly obese |
BMI is not always an accurate way to determine whether you need to lose weight. Here are some exceptions:
- Body builders: Because muscle weighs more than fat, people who are unusually muscular may have a high BMI.
- Elderly: In the elderly, it is often better to have a BMI between 25 and 27, rather than under 25. If you are older than 65, for example, a slightly higher BMI may help protect you from osteoporosis.
- Children: While an alarming, numbers of children are obese; do not use this BMI calculator for evaluating a child. Talk to your child's doctor about what an appropriate weight is for his or her age.
Doctors use a few different methods to determine whether you are overweight. Your doctor may also take your waist circumference and your waist-to-hip ratio into consideration.
In addition, a lot of other factors influence your health. These include diet, physical activity, smoking, blood pressure, cholesterol levels, and blood sugar levels.
While the exact degree to which increasing BMI levels have a bad effect on human health is unclear, most experts conclude that a BMI greater than 30 (obesity) is unhealthy. Exercise, whatever your BMI, can help reduce your risk of cardiovascular disease and diabetes. Remember to always ask your doctor before starting an exercise program.
