anorexia and bulimia are a mindset. it is an obsession. and to correct anne, to be diagnosed with bulimia you only have to have 2 incidents every week, for like...2 or 3 months. It's not every meal, and you need to eat at least 900 calories a day, otherwise you are "starving" and you CAN be anorexic when you are overweight. It's not necessarily about weight, but the mindset that comes with it. However if you aren't the "right weight" to be diagnosed as an anorextic, you would have ED-NOS. And if you don't purge frequently enough you are also classified as ED-NOS. Anorexia isn't a diet. Don't start doing anything like this because it will change you for the rest of your life and it's hard to stop once you begin.
