7.2 Nitrogen Processing Pressure

Nitrogen processing pressure rises when protein is forced beyond its structural role into energy duty. It connects protein energy pressure to renal solute load and Solute Load per Unit Energy.

Protein is necessary for structure and amino acids. Protein is not ideal as Primary Energy Substrate. Nitrogen load is a processing burden, not moral judgment—do not frame as “protein is bad.”

Backtrace: upstream food structure → energy scheduling → protein energy pressure → nitrogen processing pressure → renal outputs.

Degree protein carries energy beyond structure role.

Fatty acid pathway reduces compensatory protein energy use when structure holds.

Solute Load per Unit Energy integrates nitrogen with other solutes per energy.

Scheduling affects whether protein is pushed into energy duty.

renal solute load and urinary concentration

Urinary concentration patterns are observable outputs for backtrace—not proof that protein should be eliminated.
