The Influence of Satiation Measures on the Portion Size Effect

Completed · Not applicable

Conditions studied: Feeding Behavior

In brief

The purpose of this study is to gain a better understanding of the satiation measures that influence human eating behavior in regard to intake of large portion sizes at a meal. The investigators hypothesize that satiation measures will influence the magnitude of the portion size effect at a meal. Additionally, other individual characteristics will be examined for their influence on the portion size effect. The portion size effect will be measured by serving a test meal once a week for four weeks in which the portion size of the entree will be varied.
