It has been proposed that there is a macronutrient satiety hierarchy (1) with protein being more satiating than carbohydrate which in turn is more satiating than fat. There is also a broad consensus that the energy density (ED) of foods affects energy intake (EI) and satiety (2). Manipulating the satiating effects of foods may influence EI in human...
