3 Why Dogs Can Use FBM · 3.5 Activity Load and Substrate Use
3.5 Activity Load and Substrate Use
Canine Fat-Based Metabolism
This page is structured as definition, control variables, causal chain, observable outputs, and boundary, and serves as a canonical definition node in Canine FBM.
Activity-Load Difference is a structural node in Canine FBM, not a feeding label.
Activity load changes substrate-use ratio and recovery windows, affecting canine-FBM interpretation.
Low-to-moderate sustained activity relies more on continuous fatty-acid supply.
High-intensity activity raises demand for fast substrate scheduling.
Energy and electrolyte support determine tolerance boundaries.
As input architecture and load conditions change, Activity-Load Difference shifts long-term scheduling pathways.
When variables converge, Canine FBM is more likely to keep higher fatty-acid contribution, controlled protein energy pressure, and stable body condition.
With matched load, activity tolerance and recovery become steadier.
Under load mismatch, appetite and stool outputs are more volatile.
This page does not deny scenario-specific carbohydrate demand.
Competitive boundaries require specialized sport-nutrition layers.
