Anchor meals with protein and fiber

Build each meal around protein and fiber so a shorter window doesn’t leave you ravenous.

Why it works

Protein and fiber are the most satiating components of a meal: protein blunts the hunger hormone ghrelin and raises fullness signals, while fiber slows gastric emptying. The fewer meals you eat, the more each one has to carry, so satiety per meal is what keeps a restricted window from collapsing into a binge.

How to do it

1. Put a clear protein source at the center of every meal in the window.
2. Add fiber — vegetables, legumes, whole grains, fruit — to slow digestion and steady energy.
3. Notice fullness before reaching for more; satiety signals lag the meal by ~20 minutes.

Evidence

High-protein and high-fiber meals reliably increase satiety and reduce subsequent intake in controlled feeding studies — a well-established appetite mechanism. (rct)

Satiety is necessary but not sufficient — overall calorie balance still governs outcomes. This supports adherence, not a metabolic shortcut.

Common mistake

Breaking a fast on refined carbs alone, spiking and crashing blood sugar so hunger returns fast and the window feels unbearable.
