7.4 Renal Load under FBM Structure

Under a valid FBM structure, renal load is evaluated through energy source, protein energy pressure, Solute Load per Unit Energy, and hydration modulation—not through water intake alone.

Feline FBM does not mean ignoring kidneys. Renal evaluation must be per unit energy. Protein energy pressure and mineral structure from upstream food structure matter.

This is not a treatment system for diagnosed kidney disease. Clinical kidney disease remains in the clinical boundary layer.
