Summary  The ‘satiety cascade’ describes a series of behavioural and physiological events that occur following food intake and that inhibit further eating until the return of hunger signals. Satiety is a crucial element of the psycho-physiological mechanisms that allow adequate energy regulation and bodyweight control. Functional foods can affect satiety by acting at various moments of the satiety cascade. The present paper briefly describes recent concepts and findings about how certain characteristics of foods could enhance the intensity and duration of satiety, with potential impact on bodyweight control. The notions of energy content and energy density, glycaemic index, and the influence of nutrient and food components on satiety will be discussed, in the context of the present interest in functional foods acting on satiety.
