The population is gaining weight, despite our best current obesity education and awareness efforts. America on the Move, a nonprofit public health initiative, was founded to promote small achievable behavioral changes to help stop weight gain, starting with (1) eating 100 kcal less per day and (2) increasing lifestyle activity by 2000 steps per day. These two small changes could stop weight gain and prevent overweight and obesity in many, if not most patients. America on the Move materials and tools to implement, support and sustain these behaviors are available free of charge for individuals, schools, groups, communities, and worksites via a Web based portal. A physician tool kit is also available for health care providers to facilitate these changes in clinical practices. © 2007 Elsevier Inc. All rights reserved.
