Background: The weight-normative approach to nutrition education dominates health education programming across the United States, despite evidence that this paradigm contributes to negative outcomes including weight cycling, bias and stigma, the development of disordered eating behaviors, and weight-based bullying. Methods: This study investigates perspectives of 10 potential partners with interest in and potential to influence nutrition education. Through qualitative interviews and document analysis, researchers explored support for a weight-inclusive curriculum and factors that influence high school nutrition curricular content and implementation. Results: Findings indicate that partners hold both weight-inclusive and weight-normative values, guidance around nutrition curricular content is lacking, and state-level policy is crucial to the valuing and implementation of consistent curricula. Implications for School Health Policy, Practice, and Equity: Lack of guidance or mandated curricular content contributes to inequities across the state. Weight-inclusive curricular materials are needed. Administration must take an active role in providing access to professional development and state policy support for curricular implementation is essential. Conclusions: Weight-inclusive curriculum could serve to improve health outcomes for adolescents. However, successful implementation of, or changes to, health and nutrition curricula will require support and engagement from partners at all ecological levels.
