Truly, it's offensive. I never have said anything like that to a person before, and certainly never will. Eating disorders are just off the table for me unless I'm discussing one clinically. Yes, I come across as having a stick up the rear sometimes
but I don't find jokes or random comments about disorders of any kind funny or relative ever unless I'm sitting in a professional meeting discussing the specific disorder from a clinical aspect.
And this statement was somehow just as defeating as a "you must have had surgery" type comment. It's like the natural progression in my transformation is going to be from fat to thin to anorexic. It also makes me feel like I am somehow not in control over my own body when in fact I feel more in control now than I ever have before!
Now, if you SEE me start to divide a lettuce leaf into ten bites and take the entire lunch hour to consume it...THEN you can talk to me about anorexia. However, if you catch me taking half a browning to indulge myself on a special occasion, well that's called moderation, leave me alone.
