Urban adolescents in Cape Town face nutritional challenges that affect diet quality and school attendance. A theoretical framework will be constructed based on existing literature, focusing on gender differences in dietary intake and educational outcomes. This theoretical model provides a foundation for future empirical research into the effectiveness of targeted nutrition education programmes on adolescent health and education outcomes. Future studies should implement and evaluate gender-specific interventions using mixed-methods approaches, including surveys and observational assessments. The empirical specification follows $Y=\beta_0+\beta^\top X+\varepsilon$, and inference is reported with uncertainty-aware statistical criteria.
