A sociology professor at Purdue University has found that when white obese teenage girls lose weight, it does not guarantee that they are going to feel better about themselves. The study showed that obese teenage girls who lost weight and were no longer considered obese continued to see themselves as fat, despite clear changes in the body mass. The girls' self-esteem did not change for white girls, either, as they lost weight. They still had lower self-esteem than their normal-weight peers after they lost weight. The study used data from the National Heart, Lung, and Blood Institute Growth and Health Study and is published in the current issue of the Journal of Health and Social Behavior.
