6.1 Body Fat Change Index
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.
This index backtraces weight change into body fat, lean mass, water, and gastrointestinal content before returning to structural variables.
Human FBM focuses on body-fat scheduling and lean-mass stability, not a single weight number.
F represents body-fat storage pool, L represents lean execution tissue, and I/E represent intake and expenditure.
Insulin occupancy, leptin feedback, and water shifts determine how body-fat change should be interpreted.
Short-term weight rise or fall must be decomposed before structural judgment.
Weight change is first decomposed into F, L, water, and content shifts, then checked against scheduling-structure change.
If weight decline is mainly from L or water, it cannot be read as improved body-fat scheduling.
Under valid structure, body-fat change is more continuous, lean mass is more stable, and weight noise has less structural impact.
Weight decline driven by low energy should not be interpreted as Human FBM success.
A single weight reading cannot replace body-fat and lean-mass structural judgment.
This page is a backtrace index and provides no execution plan or outcome promise.
