What Makes a Food Satisfying?
Research during the past decade suggests there are three factors that help make a meal more satisfying: the weight of the food, the amount of protein, and the amount of fiber.
A revolutionary study done by researchers at the University of Sydney in 1995 noted that of the 38 foods tested, certain foods scored higher in satiety. Top-scoring foods included whole-meal bread, grainy bread, cheese, eggs, brown pasta, popcorn, all-bran cereal, grapes, porridge, baked beans, apples, beefsteak, ling fish (a type of cod), and oranges. All of these foods are high in fiber, water, or protein.
And which foods tend to have low satiety scores (making them much easier to overeat)? These would be foods with large amounts of fat, sugar, and/or refined carbohydrates, like potato chips, candy bars, and white bread.
