Obesity can take the form of an eating disorder, but I can tell you that teenage girls aren't "pinning" photos of morbidly obese people and ending up in a spiral that lands them in hospital.

But I hope parent commenter never has to live personally through finding out just how life destroying the predominant cultural attitudes around body form & food around us are. I wouldn't wish it on my worst enemy. Obesity is by far the least of concerns.
