4.5 Protein Energy Pressure

Protein energy pressure describes the degree to which protein is forced to carry energy demand beyond its structural role. It increases nitrogen processing pressure and Solute Load per Unit Energy.

Distinguish protein as structure material from protein as energy substrate. Pressure rises when fatty acid contribution is insufficient or when scheduling pushes compensatory protein use.

Renal solute load must be evaluated per unit energy. This is not framed as “protein is bad.”

Whether fatty acids hold primary duty or protein is displaced into energy role.

Pathway failure increases compensatory protein pressure.

Scheduling dominance can indirectly raise protein energy use.
