The aim of this study was to investigate the effects of puddings with whey protein (WP) and polidextrose (PX) on appetite feelings and energy intake. A single-blind randomized, crossover study was carried out in 25 healthy adults. Participants consumed two different puddings, including control or test pudding (12.9 g WP and 6 g PX). Two testing days were completed, including satiety questionnaires and ad libitum lunch. For all participants, energy intake at lunch was similar after consumption of control or test pudding. Consumption of test pudding did not favor subjective feelings of appetite during satiation period, but it decreased iAUC for desire to eat by 24.2% (p = .049) and marginally decreased iAUC for hunger (p = .081) by 24.3% as compared with the control during the satiety. These data suggest that the consumption of pudding with WP and PX might be a useful strategy to decrease desire of eat.
