Lunch Feeding Study for Men and Women
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.
