Body image is a component of the self. It has been estimated that a large group of males and females of heterogeneous ages and racial/ethnic backgrounds are discontent with their body image. Therefore, public opinion shows concern on the topic of body image since it has been related to eating disorders, especially anorexia and bulimia. This review summarizes the relationship between the brain areas involved in the generation and evaluation of body image and the way exercise might impact those areas to generate an accurate and objective body image. The extrastriate body area (EBA) in the brain has been recently identified as the structure primarily involved in the recognition of the human body. Further research on the EBA has to be carried out. Also, brain metabolism at rest and during exercise and its relationship with brain changes in structure and function are discussed. Finally, a summary of the effects of aerobic and resistance exercise training on body image is presented.
