The present work was to examine the influence of food deprivation on food choice. For this purpose hungry versus satiated subjects were presented with a series of choices between two snacks in a complete block design of pairwise comparisons. Snacks systematically varied with respect to subjects' idiosyncratic taste preferences (preferred versus un-preferred snack), portion size (large portion versus very small portion), and availability in terms of time (immediately available versus available only after a substantial time delay). Food choices were analyzed with a conjoint analysis which corroborated the assumption that food deprivation decreases the relative importance of taste preference and increases the importance of immediate availability of food.
