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.

Definition
Satiety and Gastric-Emptying Rhythm

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.

Control Variables
Satiety and Emptying Variables

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.

Causal Chain
Satiety Causal Chain

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.

Observable Outputs
Satiety Outputs

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.

Boundary
Satiety Judgment Boundary

“Eating less” or “longer spacing” alone cannot confirm structural validity.

Total energy, lean-mass trend, and insulin-occupancy state must be checked together.
