To direct the Secretary of Defense to develop a strategy to treat obesity as a disease and reduce the prevalence of obesity in certain Armed Forces, and for other purposes.

HR 1978 requires the Department of Defense to develop a strategy treating obesity as a medically recognized disease and reduce obesity rates among active-duty service members in all military branches (Army, Navy, Marine Corps, Air Force, and Space Force). It mandates coordinated military health programs, an educational campaign for service members on prevention and resources, and improved training for military healthcare providers to diagnose and treat obesity. The bill also requires annual reports on program effectiveness and adds data about unmet weight standards to congressional reports on enlistment, medical separations, and military readiness. These provisions aim to align military health practices with medical standards while tracking obesity's impact on operational capacity.
