Abstract: A method for treating eating disorders by repeatedly administering naloxone in a dosage sufficient to block the effects of opiate agonists to a subject suffering from an eating disorder caused by one or more related problem responses; while the amount of naloxone in the subject's body is sufficient to block opiate effects, having the subject make one of the problem responses from which the subject suffers in the presence of stimuli similar to those to which it had been learned, after the amount of naloxone is no longer sufficient to block opiate effects, having the subject make healthy eating responses to food items that do not trigger the problem responses; and continuing the steps of administration of naloxone and having one after another of the problem responses made, followed by having a naloxone-free period in which healthy eating occurs, until the problem responses are extinguished.
