Why is proper nutrition particularly important for Marines at high altitude?

Proper nutrition is crucial for Marines at high altitude primarily because of the significant physiological changes that occur in the body in response to reduced oxygen levels. At high altitudes, the body can experience unusual weight loss due to increased energy expenditure, metabolic demands, and potential appetite suppression caused by altitude sickness. Maintaining an adequate caloric intake is vital to prevent this weight loss, as it ensures the body has the energy and nutrients necessary to function optimally in the challenging conditions.

Marines require high-quality nutrition to provide sufficient energy to support their physical performance and maintain body weight against the backdrop of increased demands and potential appetite issues. Ensuring that Marines can sustain their muscle mass and overall health is essential for operational effectiveness and overall well-being while stationed at altitude.
