What is the Origin of Physiological Constraint?

A term adapted from systems biology and engineering, where constraints define the boundary conditions of a system's potential, applied here to the human body. It emphasizes the clinical reality that biology, not just psychology, ultimately dictates the limits of health optimization and must be addressed first.

What is the Mechanism of Physiological Constraint?

Constraints often manifest as a critical bottleneck in a specific pathway, such as a genetic polymorphism that significantly reduces the efficiency of a key enzyme in hormone metabolism, like the CYP450 system. They can also be acquired, such as chronic, unmanaged insulin resistance, which acts as a systemic constraint by inhibiting the anabolic signaling of multiple hormones, thereby limiting tissue repair and metabolic flexibility.

Physiological Constraint

Meaning

Any inherent or acquired limitation within an individual’s endocrine, metabolic, or cellular machinery that fundamentally prevents the attainment of a desired state of health, performance, or longevity, irrespective of psychological effort or behavioral adherence. Examples include genetically low receptor density, poor hepatic clearance capacity, or a chronic inflammatory state that inhibits hormone action. Identifying this constraint is the essential first step in effective precision medicine.
