What is the Origin of Catabolic Drift?

The term originates from exercise physiology and stress endocrinology, describing the slow erosion of adaptive capacity under prolonged energetic or psychological duress. It reflects a long-term imbalance in the body's resource allocation strategies.

What is the Mechanism of Catabolic Drift?

This drift is often driven by persistent elevation of catabolic hormones, such as cortisol, coupled with diminished anabolic signaling from growth hormone or testosterone axes. Insulin sensitivity may decrease, promoting substrate mobilization over storage and utilization. The cellular machinery gradually shifts its preference toward energy release from existing structures rather than building new ones.

Catabolic Drift

Meaning

Catabolic Drift describes a sustained, insidious shift in systemic metabolism where catabolic processes begin to dominate over anabolic ones, leading to net tissue degradation and impaired functional capacity. This state is characterized by an unfavorable shift in the hormonal milieu that favors breakdown over synthesis. Recognizing this drift early is vital for preserving lean mass and metabolic vitality.
