Holt Satiety Index
A validated ranking of foods based on their capacity to satisfy hunger per 240-calorie portion relative to white bread.
Clinical & Bioenergetic Overview
Developed in 1995 by Dr. Susanna Holt at the University of Sydney, the Satiety Index measures how effectively specific foods satisfy hunger over a 2-hour postprandial window. White bread was assigned a baseline score of 100%. Foods with high dietary fiber, protein, and water volume scored highest (boiled potatoes scored 323%, ling fish scored 225%, oatmeal scored 209%), while calorie-dense, high-fat processed items scored lowest (croissants scored 47%).
Mathematical Formula & Calculation
Real-World Worked Example
Consuming 240 calories of boiled potatoes produces over three times the subjective fullness and suppression of hunger as consuming 240 calories of white bread.
Why It Matters for Dieting
Incorporating high-satiety index foods into a caloric deficit makes hunger virtually non-existent, ensuring effortless long-term dietary adherence.
Frequent Mistakes
Consuming liquid calories (smoothies, juices, or sugary beverages), which exhibit near-zero satiety index scores and fail to trigger cephalic satiety signals.
Optimize Satiety in Deficit
Build an evidence-based diet plan that eliminates hunger.
