简要总结
The purpose of this study is to gain a better understanding of how energy density and cognitive framing of satiation using food information can influence consumption at a meal. This study also aims to investigate the influence of energy density and food information on sensory specific satiety (the decline in the subjective pleasantness of a food as it is eaten).
