‘Feeling Fat’ Feels Worse Than Being Fat
The quality of life of adolescents who think they are too fat is worse than for adolescents who really are obese. This was a result of the all Germany Health Interview and Examination Survey for Children and Adolescents (KiGGS) of the Robert Koch Institute, as presented by Bärbel-Maria Kurth and Ute Ellert in the current edition of Deutsches Ärzteblatt International.
KiGGS study, almost 7000 boys and girls aged between 11 and 17 years were weighed and asked about their self-assessment, ranging from “far too thin” to “far too fat.” In addition, they all completed a questionnaire about quality of life. As a result of their analysis, the scientists established that about three quarters of adolescents are of normal weight. Almost 55% of the girls, but just under 36% of the boys thought that they were “too fat,” although only about 18% of the adolescents were actually overweight. 7% to 8% of the adolescents were underweight.
The quality of life is lower in obese adolescents. However, this correlates to a large extent with self-evaluation. If adolescents think they are “far too fat,” they forfeit a lot of their quality of life, whatever their actual weight. This is particularly marked with girls. On the other hand, if they consider their weight “just right,” their quality of life is the same as if they were of normal weight, even if this is not true. The proportion of adolescents who think they are overweight has been increasing more rapidly in recent years than the proportion of those who really are overweight.
In an accompanying editorial, Johannes Hebebrand points out that adolescents are exposed to considerable social pressure to be thin. He thinks that it is remarkable that as many as 40% of the subjects thought that their weight was right, in spite of the ideal of slimness and the stigma of being overweight.

Perceived or True Obesity: Which Causes Min Adolescents?
Bärbel-Maria Kurth and Ute Ellert.
Introduction: The consequences of perceived obesity on quality of life are compared with those of genuine obesity in adolescents.
Methods: Within the framework of the German Health Interview and Examination Survey for Children and
Adolescents (KiGGS), the height and weight of the participants were measured. Children over 11 years of age
were asked whether they thought of themselves as underweight, normal, or overweight. As a measure of their health-related quality of life they completed the internationally employed KINDL-R generic questionnaire.
Results: While 74.8% of 11- to 17-year-old girls and boys are of normal weight, only 40.4% believe that they are just the right weight.“ Only 60.9% of obese girls and 32.2% of obese boys think of themselves as overweight. The data showed that genuinely obese adolescents, as classified by body mass index, have a better quality of life than those who only perceive themselves as being overweight.
Discussion: A realistic body image on the part of obese adolescents is a prerequisite for their acceptance of interventions. The marked deterioration in quality of life resulting from perceived obesity, even for young people of normal weight, illustrates the complexity of the struggle against obesity.
