Why does someone 'choose' to be bulimic?
There are many reasons. The first reason is genetic. There can be a history of overweight or eating disturbance in the family. There can be social and nutritional models in childhood, which were not appropriate, for instance, either overindulgence or restriction of foods and individuals may begin to learn the use of eating as a reduction of anxiety and stress which can be a learned kind of behavior. There's also the theory that individuals that have been mistreated or even sexually abused in childhood may be more prone to eating disorders such as bulimia later in their life, and then experimenting with dieting can sometimes lead to bulimia.
