If you have questions or concerns about the appropriateness of your weight, you should discuss them with your healthcare provider. It is also important to remember that weight is only one factor related to risk for disease. Although some people with a BMI in the overweight range (from 25.0 to 29.9) may not have excess body fatness, most people with a BMI in the obese range (equal to or greater than 30) will have increased levels of body fatness. For example, highly trained athletes may have a high BMI because of increased muscularity rather than increased body fatness. As a result, some individuals may have a high BMI but not have a high percentage of body fat. It is important to remember, however, that BMI is not a direct measure of body fatness and that BMI is calculated from an individual’s weight which includes both muscle and fat. Because of this, CDC has expanded the growth charts using more recent data and methods, and extended percentile. If an athlete or other person with a lot of muscle has a BMI over 25, is that person still considered to be overweight?Īccording to the BMI weight status categories, anyone with a BMI over 25 would be classified as overweight and anyone with a BMI over 30 would be classified as obese. The 2000 CDC BMI-for-Age Growth Charts have a maximum plottable BMI of 37 kg/m 2 and no percentile lines above the 95 th percentile, which makes them less useful as a visual growth tracking tool for children with severe obesity. Other risk factors the individual has for diseases and conditions associated with obesity (for example, high blood pressure or physical inactivity).The individual’s waist circumference (because abdominal fat is a predictor of risk for obesity-related diseases).For assessing someone’s likelihood of developing overweight- or obesity-related diseases, the National Heart, Lung, and Blood Institute guidelines recommend looking at two other predictors: It is also important to remember that BMI is only one factor related to risk for disease.
