2 Why High-Carbohydrate Frames Fail · 2.4 Insulin Occupancy
2.4 Insulin Occupancy
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.
Insulin occupancy describes how strongly insulin occupies long-term energy allocation.
It is used to determine whether the system remains carbohydrate-scheduled or shifts toward fatty-acid scheduling.
Exogenous carbohydrate frequency and magnitude shape occupancy duration and ceiling.
Meal rhythm changes occupancy density and recovery windows.
Occupancy state and body-fat accessibility jointly shape substrate allocation.
Persistently high occupancy limits fatty-acid mobilization and reinforces repeated carbohydrate scheduling.
Reduced stable occupancy enables higher long-term fatty-acid direct energy share.
Reduced occupancy often coexists with smoother post-meal states and reduced hunger variance.
Repeated occupancy spikes often coexist with stronger energy volatility and intake impulses.
Insulin interpretation cannot be reduced to a single glucose reading.
This variable belongs to structural nutrition interpretation, not medical-care claims.
