There is a lot of research in the field of psychology looking at how modern media and culture influences self-image. With the media glorifying and presenting more and more unrealistic ideals, many people have body image issues. For example female runway models’ waist size/BMI is getting smaller and smaller over time (so that clothes look better on them on the runway) and thus women think this unrealistic and unhealthy body type is the ideal. This extreme low weight (anorexia) can lead to several issues from reproductive issues, mood affects, and bulimia and in the worst case death.
We see similar things in men, although not as dangerous, where from a young age kids see all there superheroes as big and strong – this can possibility attribute to another disorder that is more prevalent in men than anorexia, called muscle dismorphia. This is where the sufferer thinks he is much smaller than he actually is and continually strives to put on more muscle mass. This can lead to making unhealthy choices to fulfil these desires.
