Both the hedonic ratings and the reinforcing value of food have been considered to be determinants of food intake. The objective of this study was to compare the pleasurable ratings and the reinforcing value of food as determinants of energy intake. Seventy-four smokers were studied in food consumption and reinforcing value of food tasks prior to enrolling in a smoking-cessation treatment program. For the food consumption task, the participants tasted and consumed food ad lib from eight snack foods. The reinforcing value of the food task assessed how hard subjects would work for a preferred snack food. Results showed that food reinforcement was related to laboratory food intake, with those high in food reinforcement consuming significantly more calories (+114.4 kcal, P<.01) than did the participants low in food reinforcement. Food reinforcement was related to food intake for the preferred food as well as to total energy intake. Hedonics for the preferred food was related to food reinforcement but not to either measure of laboratory energy intake. In multiple-regression models, food reinforcement and the interaction of food reinforcement by sex were significant predictors of energy intake for the preferred food and for total energy intake, along with baseline hunger. In conclusion, energy intake in smokers in a laboratory setting is more strongly related to food reinforcement than to the hedonic ratings of food.
