5.2 Satiety, Meal Spacing, and Gastric Emptying
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.
Fat and protein together raise post-meal satiety signals and change gastric retention and energy-release rhythm.
In Human FBM, longer meal spacing usually reflects a changed energy-release curve, not a simple reduction in total intake.
Meal structure determines daily energy-release density and insulin-occupancy volatility.
Fat and protein ratios influence gastric retention time and post-meal release speed.
Gastric-emptying speed determines timing and absorption load of fatty acids entering the small intestine.
Total energy level and adaptation phase determine whether satiety signals remain stable.
When fat and protein raise post-meal satiety, gastric emptying slows and energy release becomes more gradual.
With sufficient total energy and stable structure, inter-meal hunger volatility usually declines and intake rhythm becomes more regular.
Under stable structure, common outputs include lower inter-meal hunger, weaker intake impulse, and reduced post-meal sleepiness.
If total energy is insufficient, longer meal spacing may reflect stress output and should not be read as fatty-acid steady state.
“Eating less” or “longer spacing” alone cannot confirm structural validity.
Total energy, lean-mass trend, and insulin-occupancy state must be checked together.
