Physical Activity and the Health of a Nation: A National Challenge and Collective Response.

Historic recruitment and retention challenges confront the U.S. military. In an invited panel discussion at Lifestyle Medicine 2023, we argued that widespread physical inactivity is contributing to these challenges, and that Lifestyle Medicine approaches should be part of the solution. Our aim in this commentary is to recapture the most salient messages from that discussion. First, we summarize significant epidemiologic studies that describe the scope of the problem among future recruits, current service members, and Veterans. Then, in the optimistic spirit that characterizes both the armed forces and Lifestyle Medicine communities, we outline several potential solutions. By increasing physical activity during the school day, using wearable technology to monitor and prompt health behaviors, addressing the other pillars of Lifestyle Medicine (especially sleep, nutrition, and stress management), aligning efforts with current health frameworks in the Departments of Defense and Veterans Affairs, and recruiting Lifestyle Medicine professionals, we are convinced that we can improve the health of our nation and, in so doing, strengthen military readiness and national security.
