Biological Demand

Meaning

Biological Demand represents the collective energetic, structural, and regulatory requirements placed upon a physiological system at any given moment to maintain homeostasis and execute necessary functions. This concept quantifies the total expenditure of resources—including oxygen, glucose, amino acids, and hormonal signaling—needed for survival, repair, and adaptation. A high biological demand, such as during intense exercise or illness, necessitates a proportional increase in systemic resource allocation and hormonal output. Clinical assessment of this demand helps determine the appropriate level of nutritional and therapeutic support required for optimal health outcomes.
