Abstract
The effects of hunger on expressed food preferences and on the correlation of preferences with consumption were tested. A change from ad libitum feeding in an environment entailing high energy outlay to a condition of underfeeding in the same environment changed the level but not the order of subjects' preferences for 29 U.S. Army meal-type C-ration items. The correlation of preferences with consumption in the ad libitum condition was higher than observed in previous studies, while the correlation in the underfed condition (when subjects consumed almost all available food) was lower than previously observed. In general, the data suggest that preference becomes more salient, relative to food satiety or caloric qualities, as a predictor of consumption as caloric need increases.
