no, I don't get the impression that she has an eating disorder. She doesn't seem too neurotic about food intake or talk about having body dysmorphia. If anything her eating pressure seems external.
Then again, maybe she does have disordered eating..
What the blog sheds light on for me is the discrepancy between coaches/parents expectations Vs. medical advice on what's healthy.
The girl is getting feedback that she needs to LOSE weight and eat LESS from coach and family while a medical doctor is pointing to a stress fracture and amenhorrhea as warning flags that she is either underweight or undernourished and if anything needs to eat MORE. It is apparent that they suspect an eating disorder when the examine her knuckles (for scarring - sometimes present with bulimia).
I think the girl mentions at the beginning of her blog that she comes into the year at 5'8" and 120. This is already low end of normal, getting close to underweight. So (unless she gained a lot of weight during the season) how much weight can they expect her to lose??!!
BTW: Protagonist is the word, not antagonist.
