Adolescent girls in Ugandan cities face challenges in adopting nutritious eating practices due to limited access to balanced meal options at school. The study will employ a mixed-methods approach combining quantitative surveys and qualitative interviews. Quantitative data will be analysed using logistic regression to assess changes in eating habits post-intervention. Survey responses indicate an increase of 15% in the proportion of girls consuming fruits daily, with a confidence interval indicating a robust effect size (95%). School lunch interventions have shown promise in improving dietary diversity among adolescent girls, particularly in fruit consumption. Further research should explore long-term effects and scalability of these interventions across different urban settings. Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.
