The author takes an intellectual approach but never provides the reader with any suggestion that she has real insight into the underlying issues that undoubtedly drove her to an eating disorder in the first place. In fact, very little real emotion is expressed throughout this rather straightforward, almost dry read. The book is filled with descriptions of symptomatic behavior and weight numbers (although she doesn't give her height, she might as well, as it's easy to figure out in context). She is far more interested in describing her concerns and behaviors with food, calories and weight than she is in delving into the issues which might have brought her to the point of near-fatal illness. Compounding her eating disorder is OCD, adding to an undoubted biochemical influence. Because of the OCD it is likely that the anorexia nervosa is secondary and is actually more of a food phobia directly associated with OCD than it is anorexia nervosa per se. The behaviors and the consequences of those behaviors are, of course, the same.
Regardless of the disorder's actual diagnosis, phobias don't exist without a stimulus. Something initiates them. Even to the casual reader of this book, issues pop out: enmeshment with parents, perfectionism, leaving home, fear of taking on adult responsibilities, etc., etc., and yet Carrie Arnold only briefly glosses over these if even directly mentioning them at all. I hope she has actually addressed her issues in therapy.
I suspect that far from the optimism she radiates at the end of the book, when she is proclaiming recovery, that in actuality this young woman is far from finished with dealing with her issues or her phobias....
