From the Introduction: "Some Members of Congress have repeatedly expressed interest in maintaining a ready and capable military. Meeting readiness and capability requirements includes preserving the health and fitness of American servicemembers. Various factors, including physical fitness, body composition, access to nutritious foods and the nutritional content of foods consumed, may affect the health of servicemembers and their ability to conduct military operations. [...] According to the National Center for Chronic Disease Prevention and Health Promotion within the U.S. Centers for Disease Control and Prevention (CDC) [hyperlink], poor nutrition contributes to 'many costly diseases, including obesity, heart disease and some cancers.' According to the Department of Defense (DOD), obesity is a worsening issue for servicemembers. In the 2019 Health of the Force Report [hyperlink] 'the overall prevalence of obesity has steadily increased since 2015' and had reached 17.9% among active component servicemembers. DOD has undertaken various efforts to promote the health of servicemembers and military readiness."
