2 Why High-Carbohydrate Frames Fail · 2.1 Calorie Arithmetic Is Not Metabolic Fit
2.1 Calorie Arithmetic Is Not Metabolic Fit
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.
Calorie arithmetic is an energy-measurement layer, not a metabolic-scheduling explanation layer.
Metabolic fit requires joint reading of input structure, hormonal allocation, and tissue-state variables.
Exogenous carbohydrate input defines baseline glucose-scheduling pressure.
Insulin occupancy defines fatty-acid access and duration.
Lean-mass state and energy expenditure define system execution capacity.
Equal calories under different carbohydrate structure can produce different occupancy patterns and substrate allocation.
Therefore equal calories do not imply equal long-term metabolic operation.
Hunger variability and post-meal states can diverge under equal-calorie plans.
Body-fat allocation stability and energy continuity can also diverge.
This page does not reject calorie accounting.
It rejects calories as a single-layer explanatory framework.
