"The next mouthful will be the best": influence of prevision of the pleasure on the decision of having a second helping of a just eaten food

Purpose Firstly, to see if the decision to have a second helping of food is related to the current evaluation of its palatability or to the predicted pleasure of a second helping of the same food. Secondly, to see if there is any relationship between subjects' BMI, their current or predicted evaluation of food palatability and their decision to have a second helping. Methods 128 guests attended a village festival with the specific purpose of eating a traditional, local soup made of beans and bacon. Subjects were asked to indicate the pleasure they felt eating the soup and the pleasure they predicted they would feel by having a second helping of the same food. Subjects were then offered a second identical portion of the above described soup. Results 72 subjects accepted a second helping of the soup. We discovered a significant correlation between predicted pleasure and the decision to have a second helping of the same food. There was also a significant correlation between BMI and the level of predicted pleasure of a second helping. Conclusions The decision to have a second helping of food was related to predicted pleasure and not to the pleasure that was experienced during the first helping.
