Considering the difficulties of the psychoanalytic clinic with obese patients, this paper intents to explicit the link between the self-image and the proper body, placing them in relation to the subject's libidinal economy. Since Freud's considerations about the narcissism, we will follow the development of the optical scheme in the lacanian theory to delimitate how the self structure have a libidinal rest that can't be projected in the speculate image. We will follow Lacan's teaching in relation to the interlacement between the functions of the ideal ego and the ego ideal, to analyze the function that the obese body plays for people who complain about the weight excess.
