Study Summary
The study uses a crossover design in which the portion size of food is varied at each meal. Across four test meals, subjects will be served four different portions of food, and intake will be determined from pre- and post-meal food weights. The first visit will be a screening visit, at which subjects will complete the consent form, have their height and weight measured, and rate the taste of the study food. Test meals will be scheduled once a week for four weeks. At visits 2-5, subjects will eat lunch and rate characteristics of the meal. At visit 6, subjects will complete various questionnaires. The objective of this study is to determine whether any individual characteristics related to satiety influence the effect of portion size on intake.
