Here is my opinion on what causes Anorexia Nervosa. Since there is barely any evidence as to a single cause, and limited studies are ongoing, we don’t really know what causes it, but I have always believed that it is caused by a genetic mutation. A recent study (and this isn’t the first article I read, but it’s all I could find in a quick search) showed that it is linked to a genetic mutation. Something about the body not being able to read something right. I can’t remember the specifics and the article I linked doesn’t have all the information that the other one had. But I completely agree with this study. I just do not think that social media and peer pressure can cause an eating disorder.
Disordered eating, maybe, but not a full blown ED. Maybe it can help push the development, but everyone is exposed to the same media. Everyone sees the same pictures. Everyone reads the same articles. We know what the media thinks a person should look like, and we know what we actually look like.
So why would only some people develop eating disorders and not others? If the media and social pressure was the cause then everyone would have an eating disorder. No, it’s psychological. It’s a genetic issue. Those things probably do not help, but they are not the cause. Eating disorders aren’t new. Long before the internet and photoshop people got eating disorders. It’s a genetic thing.
Anyway, that’s what I believe. That’s what makes sense in my head.
EDIT: I also just joined this! I want to more seriously try to lower my body fat percentage, so I’ll be running/walking three times a week and doing HIIT three times a week, so my mileage goal isn’t very big. Doing this instead of NaNoWriMo. http://runeatrepeat.com/2013/10/29/pile-on-the-miles-20135th-annual-challenge/
