The National Academies Roundtable on Obesity Solutions hosted an April, July, and October, 2022 workshop series to explore the gaps in knowledge within the foundational drivers of obesity. Facilitating action will require improved health communication, deconstructing structural racism, and recognizing the biased mental models and social norms at odds with obesity solutions. Speakers discussed future research in evidence-based solutions and potential ways to translate current evidence into practice. This Proceedings of a Workshop summarizes the discussions held during the workshop.
