The Global Goals to end hunger requires interpretation of problems, and change across multiple domains. We facilitated a workshop aimed at understanding how stakeholders problematise sustainable diet transition (SDT) among a previously-marginalised social group. Using the systems thinking approach, three sub-systems, access to dietary diversity, sustainable beneficiation of natural capital, and 'food choice for well-being', highlighted the main forces governing the current context, and future interventions. Moreover, when viewed as co-evolving processes within the multi-level perspective, our identified microlevel leverage points - multi-faceted literacy, youth empowerment, deliberative policy-making, promotion of sustainable diet aspirations - can be linked and developed through existing national macrolevel strategies. Thus, by reconsidering knowledge use in the pursuit sustainability, transformational SDT can streamline multiple outcomes to restructure socio-technical sectors, reconnect people to nature-based solutions and, support legitimate aspirations. The approach could be applied in countries having complex socio-political legacy and to bridge the local-global goals coherently.
