Satiety Index Food List: Foods That Keep You Fullest Per Calorie

Complete satiety index food list ranking protein leverage, water volume, and appetite suppression.

What Is the Satiety Index?

The Satiety Index was originally developed by Dr. Susanna Holt at the University of Sydney in 1995 to measure how effectively different foods satisfy hunger and suppress appetite over a 120-minute post-meal period per equal caloric portion (240 kcal).

Using white bread as a baseline standard of 100%, foods were ranked based on their ability to prevent subsequent food intake. Foods scoring above 100% offer superior fullness per calorie, while foods scoring below 100% trigger rapid rebound hunger.

The Satiety Index Score Hierarchy

Food Category / Item	Satiety Index Score	Key Satiety Mechanisms
Boiled White Potatoes	323% (Highest overall)	High water volume, resistant starch formation, high mass
Fish (Salmon, Cod, Halibut)	225%	High protein leverage, amino acid induced GLP-1 release
Oatmeal & Porridge	209%	Beta-glucan soluble viscous fiber gels in stomach
Oranges & Apples	202%	High water content, intact pectin cell matrix
Beef & Lean Poultry	176%	Peptide YY (PYY) trigger, slow gastric peptide digestion
Eggs	150%	Complete amino acid profile, choline, steady insulin response
White Bread (Baseline)	100%	Standard reference point
Croissant & Bakery Pastries	47% (Lowest overall)	High refined sugar + hyper-palatable fat combination

The 4 Biological Pillars of High Satiety

Why do certain foods keep you satiated for hours while others make you hungrier minutes later? Satiety is governed by four distinct physiological drivers:

1. The Protein Leverage Hypothesis

Protein is the single most potent macronutrient for appetite suppression. Consuming protein stimulates the gut endocrine cells to release Peptide YY (PYY) and Glucagon-Like Peptide-1 (GLP-1) while suppressing Ghrelin (the hunger hormone).

2. Gastric Distension (Stomach Stretch Receptors)

Mechanoreceptors in the muscular stomach wall respond directly to physical volume. Foods rich in water and bulk (such as leafy vegetables, boiled potatoes, and broths) stretch the stomach lining, sending immediate satiety signals via the vagus nerve to the hypothalamus.

3. Viscous Soluble Fiber

Soluble fibers (such as beta-glucan in oats and mucilage in chia seeds) form a thick gel-like matrix in the digestive tract. This delays gastric emptying and slows down nutrient absorption, providing a smooth, prolonged release of energy.

4. Low Reward & Low Palatability Density

Hyper-processed foods that combine refined carbohydrates with added fats and sodium bypass the body’s natural satiety feedback loops by over-stimulating dopamine pathways in the brain. Whole single-ingredient foods maintain healthy leptin sensitivity.

How to Build a High-Satiety Meal

To maximize satiety per calorie on every plate:

Anchor with Protein: Aim for 30g–40g of protein from fish, eggs, cottage cheese, or lean poultry.
Add Volumetric Fiber: Include 150g–200g of water-rich vegetables or boiled tubers.
Avoid Liquid Calorie Traps: Avoid sugary drinks or excessive added oils that provide zero gastric stretch.
