4.4 Fatty Acid Energy Pathway

The fatty acid energy pathway is the route by which fatty acids become usable long-term Primary Energy Substrate. It requires freshness, digestion, bile salt dispersion, enzyme processing, absorption, transport, and oxidation.

This is not just eating fat. Pathway continuity matters. Fat Processing Rate is a control variable. Unstable fat state from Fat Freshness Boundary violation can disrupt outputs.

Insulin regulation state must allow oxidation to remain active when structure supports fatty acids as primary substrate.

Stable fat state before processing begins.

Rate of digestive accommodation through the fat route.

Scheduling must permit oxidation pathway activity.

Steps that make fat enzymatically accessible.

Post-absorption delivery to utilization.

Soft stool, greasy coat, or digestive discomfort may indicate pathway break—not proof that dietary fat should be abandoned by default.
