The Roundtable on Obesity Solutions convened a 1.5 day public virtual workshop on Thursday, October 28 (10:00 am to 2:45 pm ET) and Friday, October 29 (1:00 pm to 4:00 pm ET). This third workshop in the series explored how to advance strategies for sustainable systems-wide changes that leverage the three drivers (biased mental models/social norms, structural racism, and health communications) introduced in the first two workshops that can inform actionable priorities for individuals, organizations, and policymakers to reduce both incidence and prevalence of obesity.
