Ever since EDNOS was switched to OSFED, and the atypical anorexia label came into use, a lot of fat bitches have claimed to have it. However, they're usually smart enough to claim it was the OSFED diagnosis, and not full blown anorexia nervosa, because they realize that you have to have a BMI of 17.5 or lower to be diagnosed with AN (though this was taken out of the DSM 5 because many ED sufferers obsessed over this number). An example of atypical anorexia would be, a woman who is 5'4" used to weigh 200 pounds, and puts herself on a 500 calorie day diet, coupled with days where she would fast. Within a few months, her weight drops to 110, and if she keeps losing weight, she will quickly get into an underweight BMI, and her ED behaviors will get even more extreme, because starvation completely changes your brain chemistry and you will become even more entrenched in the OCD behaviors. This is the type of woman they want to put into treatment, despite still having a normal BMI (though on the lower end of healthy), because treatment just becomes harder and more complicated when you reach an underweight diagnosis, not to mention all the health problems that come with it.
Also, before the atypical diagnosis, many a woman who suffered from a restrictive eating disorder would become even more extreme in trying to achieve the coveted 17.5 BMI (or lower), because eating disorders are, unfortunately, seen by many of those who have one as a competition on who's more sick, and therefore, who can show the most control. If you have ever seen the pro ana sites before the big crackdown on them, you would see the fierce competition, and you would see the severe anorexics felt extremely proud that they were a weight that few could ever get to and maintain, and some of them even felt having anorexia made them superior.
Tess has never once struggled with any restrictive eating, unless she thinks that because she only had 4 doughnuts and not 8 means she's starving herself. It makes my blood boil when fat bitches like Tess claim they suffer from anorexia or restrictive eating. Mainly, because I know real anorexics probably freak the fuck out when some landwhale claims they suffer just like them. And I've known a few anorexics who have relapsed, or refuse treatment, because they are terrified of ending up like someone like Tess.
