Interoceptive Exposure Therapy (IE) targets food avoidance in Anorexia Nervosa. Each session the therapist weighs the patient, checks-in, and reviews weekly homework. Sessions occur weekly for 20 weeks, with the first session lasting 1.5 hours and the remaining sessions one hour. Early sessions include using exposure to foods and counterconditioning to pair a positive stimulus with a food that would typically produce food avoidance. Parents are trained to model this at home. Sessions mid-way through address the use of non-judgmental description of appearance during mirror exposure. Sessions at the end of the 20 weeks are focused on recognizing change, planning for future obstacles, and developing a relapse prevention plan to continue practicing distress tolerance, counter-conditioning, and food/body exposure.

Family-Based Therapy (FBT) includes parent-enforced contingencies to increase value of eating and decrease the value of food avoidance. Each session the therapist weighs the patient, checks-in, and reviews weekly homework. Sessions occur weekly for 20 weeks, with the first session lasting 1.5 hours and the remaining sessions one hour. Sessions consist of checking in with the patient, discussion of the week's implementation of refeeding, and helping parents separate the illness from their child. In session 2, a family meal provides the therapist with an opportunity for direct observation of the familial interaction patterns around eating. The therapist makes careful and persistent requests for united parental action toward re-feeding and/or regulating eating habits, the primary concern at this point of the treatment, and the therapist tries to create and reinforce a strong parental alliance around efforts at feeding the child.
