Scottie,
unfortunately I am going to have to disagree with your statement about eating disorders no longer being acceptable in the dance world. in some ways it is almost worse than gymnastics because it is adults dancing and not children, as far as professional companies go. most dancers in companies do not have figures, as the normal woman would, there are no curves.
Eating disorders are extremely common for a large part because dancers spend an unnatural amount of time looking at themselves in the mirror each day. the time spent in class is spent studying your line and how your body looks. amy person would be selfconcious about their looks after that much examination.
Also, some companies and dance schools still have "weigh ins" for their dancers and those that do not meet their required weight are often put on probation.
