Over the past two decades in the United States, obesity has become a public health crisis of epidemic proportions. At present, approximately 64% of all U.S. adults are overweight, including 30% who are obese. Overweight and obesity are associated with increased morbidity and mortality, and also exact significant economic costs. The medical expenses attributable to overweight and obesity are estimated to have reached as high as $92.6 billion per year—roughly 9.1% of total U.S. medical expenditures.1 A number of efforts to address and reverse this public health crisis have been and are being undertaken in the public, private, and nonprofit sectors. This report is the final work product of one such effort—the Keystone Forum on Away-From-Home Foods: Opportunities for Preventing Weight Gain and Obesity. The Keystone Forum was requested and funded by the U.S. Food and Drug Administration.2 The Forum brought together a wide diversity of participants to develop joint recommendations for action. The participants included representatives from industry, government agencies, civicsector organizations, and academia. (A complete list of participants can be found in Appendix A of the report.
