Body dissatisfaction or the motivation to adopt a healthier diet are two of the main reasons for engaging in food restriction or dietary changes, such as becoming vegetarian or vegan. Both of these circumstances, in vulnerable populations, increase the risk of developing an eating disorder. Changes in eating patterns can foster an obsession with progressive, limitless restriction or, conversely, with healthy food, rejecting entire food groups as harmful (mainly due to their caloric content). Once the disorder has taken hold, it becomes difficult to discern the true reasons for rejecting certain foods like meat or fish. It is here that vegetarianism or veganism, for a person with an eating disorder, can become an adaptive way to justify the dietary change , potentially overshadowing other motivations, such as philosophical ones.
