The Body Logic Program for Adolescents was developed as a two-stage intervention to prevent the development of eating disorder symptoms. Preliminary results indicate that this program shows promise as an effective prevention effort. The current article provides a detailed description of the protocol for implementing Body Logic Part I, a school-based intervention. A brief review of Body Logic Part II, an intensive family-based intervention for high-risk students, is also provided. Examples of exercises are introduced and goals for practitioners are discussed. The authors hope that by providing this in-depth description of the protocol, researchers and clinicians can use this program in future prevention efforts.
