Each woman image that we see in magazines, on publicity stands or on television suggests us that the sexual, financial and social success will be obtained only if a woman will be supple. Because of that, the people wish, and especially, the woman wish to slim is so powerful that can cause grave nutrition disorders. One of these disorders is anorexia nervosa witch incidence increased a lot in the last period throughout the world. The people that present anorexia nervosa have a deformation image about their body, thinking they are fat even in the periods they are under their normal weight. The apparent control about food behavior, restrictive diets offers a false self-control of patients with anorexia nervosa in their life day by day. The personality traits, establishing the perception of a certain body image, can influence the length, the evolution and the form of anorexia nervosa. The perfectionism, inflexibility and the absence of emotional expression are common personality traits of people with anorexia nervosa, in special in restrictive type. These patients strive to make all things perfect, without mistakes, in concordance with the self-imposed and of parent's imposed standards.
