The National Academies of Sciences, Engineering, and Medicine is seeking suggestions for experts to be considered for membership to the Roundtable on Obesity Solutions. Since 2014, the Roundtable on Obesity Solutions has been the only national, multisector convener bringing together a variety of voices with a shared and dedicated focus on obesity. Through meetings, workshops, publications, and Innovation Collaboratives, the Roundtable fosters ongoing dialogue on emerging science, evaluation, and innovation efforts in obesity prevention, treatment, and management for children and adults. The Roundtable explores and advances solutions at the systems level. Using these suggestions, the National Academies staff will be looking to fill ~2-3 open seats on the ~35-member Roundtable of volunteer experts, in addition to collecting information for potential future speakers and participants.
