Background: Several studies discuss the relationship between excessive physical exercises and eating disorder patient as a strategy to lose weight. Objective: Review the literature concerning physical exercises in eating disorder patients including definitions, diagnostic criteria and therapeutic proposals. Methods: A literature review was done through MedLine, LILACS and Cochrane databases using the terms “eating disorders”, “anorexia nervosa”, “bulimia nervosa”, “physical activity”, “obligatory exercise”, “compulsive exercise” and “excessive exercise”. Results: 12 articles in a sampling of 80 were selected. These articles include the investigation of a physical pattern that was considered excessive in adults over 18 and the use of evaluation instruments. The practice of physical exercises in patients with disturbed eating behaviors is revised. Discussion: There is no consensus in literature about diagnostic criteria and instruments to consider the physical exercise as inadequate or excessive and its use as a way to lose weight. On the other hand the practice of physical exercises along the treatment of eating disorder patients could be beneficial if oriented and supervised.
