Physiological Expenditure

Meaning

Physiological Expenditure refers to the total energy and functional cost incurred by the body to maintain life, adapt to stressors, and perform daily activities, encompassing basal metabolism, physical activity, and the energy required for digestion and repair. This expenditure is a dynamic, measurable output reflecting the body’s overall metabolic workload and energy utilization efficiency. In the context of wellness, understanding this expenditure is key to balancing energy intake and output, as chronic over-expenditure without adequate recovery can lead to HPA axis dysregulation and metabolic burnout.
