The Proceedings of the National Summit on Legal Preparedness for Obesity Prevention and Control is based on a two-part conceptual framework composed of public health and legal perspectives. The public health perspective comprises the six target areas and intervention settings that are the focus of the obesity prevention and control efforts of the Centers for Disease Control and Prevention.This paper presents the legal perspective. Legal preparedness in public health is the underpinning of the framework for the four “assessment” papers and (...) the four “action” papers that are integral to the application of public health law to any particular health issue. In addition, this paper gives real-world grounding to the legal framework through examples that illustrate the four core elements of legal preparedness in public health that are at work in obesity prevention and control.
