In addition to ED's there is also something Ive heard of called "disordered eating". I dont know if thats its own ED or not but IMO it isnt all that healthy. The idea behind disordered eating is a preoccupation with food, calorie intake, meals, etc.
Also preoccupation with your physical body and appearance. Disordered eating involves unrealistic restrictions with foods and sometimes a bargaining phase where you might make deals with yourself- I.E. " I am going to only eat 550 calories for the next five days and binge on the weekend". Of course I do not know if any of this qualifies as an ED but IMO it should. I had disordered eating and an unhealthty obsession on body and weight but never quite made the threshhold for an ED.
