2.6 Diet Label Is Not Metabolic State

Human 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 Human FBM.

Definition
Label-State Separation

Diet labels are naming categories, not metabolic states.

Metabolic state is jointly produced by input architecture, occupancy status, energy sufficiency, and tissue stability.

Control Variables
State Variables

Under the same label, exogenous carbohydrate frequency can differ substantially.

Under the same label, total energy and lean-mass trajectories can differ substantially.

Under the same label, occupancy trend and fatty-acid contribution can differ substantially.

Causal Chain
Label Misclassification Chain

Directly equating labels with metabolic state skips control variables and creates classification errors.

Variable-level reading explains why identical labels can produce divergent long-term outputs.

Observable Outputs
Divergent Outputs

Identical labels can still produce divergent hunger curves and post-meal states.

Identical labels can still produce divergent body-fat allocation stability and execution sustainability.

Boundary
Usage Boundary

Labels can support communication categories but cannot replace mechanism judgment.

Structural interpretation must return to input, occupancy, energy, and tissue variables.
