Striving for the perfect body can take its toll, both physically and mentally. This column shows how excessive preoccupation with self-appearance can give rise to preventable eating disorders, such as anorexia and bulimia, among European females. It is time for policy action to shift people’s perceptions of their ideal body closer to what is healthiest.

Policy interventions to curb the parallel epidemics of excessive preoccupation with self-image and food disorders, such as bulimia and anorexia, are increasingly being used, including the regulation of the fashion industry and advertisements, as well as support campaigns through social networks (Borzekowski et al. 2010) and the media (Burke 2009). In some European countries, there has been increasing debate over the conditions, especially since the Brazilian model Ana Carolina Reston died from anorexia in 2006.

More generally, it is becoming increasingly apparent that standards of physical appearance are important and powerful motivators of human behaviour, especially regarding health and food. Excessive preoccupation with self-image is regarded as a contributing factor to the proliferation of food disorders, especially among young women. Anorexia, together with other food disorders such as bulimia nervosa, can be characterised by a distorted body image accompanied by an eating obsession.

Social sciences regard social image as being continually under construction and essential in determining physical, psychological, and social equilibrium. Hence, one can expect a tension between aesthetic and other reactions to food ingestion. When applied to food disorders, this could explain some of the extreme forms of weight aversion – particularly those that require policy attention.

We argue that a distorted self-image influences health-related behaviours, specifically food disorders. We test our claims empirically using European data and find evidence consistent with Figure 1, namely that those females with a distorted self-image choose a net caloric intake that is under the optimal net caloric intake. The distortion is explained by the influence of ‘peer weight’ (which is likely to influence self-image or social identity) on the likelihood of anorexia, and the influence of self-image on individual weight. We support the hypothesis that social pressure through peer shape is a determinant in explaining anorexia nervosa and a distorted self-perception of one's own body.
