Bmi: How Much Should I Weigh

The Centers for Disease Control uses BMI, or body mass index, as a screening tool to identify weight-related health risks in adults. By requiring only two measurements -- height and weight -- the BMI scale is simple to apply, making it a convenient tool for individuals and clinicians. You can look up your current and recommended BMI scores online. Discuss your BMI score with your doctor to help you determine if you need to make changes in your weight.

Healthy

Ideally, we should all weigh within a healthy range. For adults age 20 and over, a BMI range of 18.5 to 24.9 falls into a healthy range. Your percentage of body fat does not increase your risk of heart disease, cancer or diabetes. A 5-foot-9-inch adult with a healthy BMI score weighs between 125 and 168 lbs.

Overweight

More than 30 percent of American adults fall into the overweight BMI category, with a score between 25 and 29.9, according to the Weight Control Information Network. Overweight people carry their excess weight as a mix of bone, muscle, body fat and water. A 5-foot-9-inch adult with an overweight BMI score weighs between 169 and 202 lbs.

Obese

Obese adults carry an excessive amount of body fat on their frames. An additional 30 percent of Americans fall into this category, with a BMI score between 30 and 39.9. A 5-foot-9-inch adult with an obese BMI score weighs more than 203 lbs. Individuals in a subset of this category, the morbidly obese, have a BMI over 40 and weigh more than 100 lbs. over their recommended BMI weight. About 5 percent of the American population falls into this range, according to the National Center for Health Statistics.

Recommendations

As of 2010, obesity has reached epidemic levels in America, reports the U.S. Department of Agriculture. New dietary guidelines strongly recommend weight-control measures for all Americans, including reducing sugar, fat and sodium, and increasing vegetables and nutrient-dense foods. Talk to your doctor about using your BMI score as a means to assess and address your weight.
