Body mass index A good way to decide if your weight is healthy for your height is to figure out your body mass index (BMI). You and your health care provider can use your BMI to estimate how much body fat you have. Being obese puts strain on your heart and can lead to serious health problems. These problems include: Heart disease High blood pressure Sleep apnea Type 2 diabetes Varicose veins 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 your BMI falls 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 Extreme or high risk obesity BMI is not always the best way to decide whether you need to lose weight. If you have more or less muscle than is normal, your BMI may not be a perfect measure of how much body fat you have: Body builders: Because muscle weighs more than fat, people who are very 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 thinning of the bones (osteoporosis). Children: While an alarming number of children are obese, do not use this BMI calculator for evaluating a child. Talk to your childs doctor or nurse about the appropriate weight for your childs age. Health care providers use a few methods to decide whether you are overweight. Your health care provider may also take your waist circumference and waist-to-hip ratio into consideration. Your BMI alone cannot predict your health risk, but most experts say that a BMI greater than 30 (obesity) is unhealthy. No matter what your BMI is, exercise can help reduce your risk of heart disease and diabetes. Remember to always ask your health care provider before starting an exercise program.
