The present study tested whether foods categorized as meals reduce subsequent intake more than isocaloric foods categorized as snacks. The study was repeated three times with variations. In each variation we manipulated whether subjects received meal or snack foods in an isocaloric load. In Variation 1, subjects consumed less following a load of meal foods than snacks. Variation 2 found this effect to be short-term, affecting food choice 20 min following a load but not 3 h later. Variation 3 demonstrated: (1) this effect occurs independent of the effects of the weights of foods, and (2) this effect varies specifically with subject perceptions of foods (i.e. whether they are part of a meal or snack). These results are discussed in terms of how cognitive representations of preload foods can influence subsequent consumption.
