Study Summary

Primary Objective: To examine whether the consumption of preloads varying in protein quality effect subsequent meal energy and macronutrient content Secondary Objectives: To examine whether the consumption of preloads varying in protein quality effect postprandial feelings of hunger, fullness, desire to eat, prospective food consumption, and eating initiation. Exploratory Objective: To examine whether the consumption of preloads varying in protein quality effect postprandial cognitive performance.

Primary Outcome

A questionnaire assessing perceived hunger will be completed at specific times throughout each of the the 4-h testing days. The questionnaire contains a 100 mm VAS incorporating a horizontal line rating scale for each response. The questions are worded as "how strong is your feeling of" with anchors of "not all" to "extremely." The range is 0 mm (min hunger) and 100 is max (hunger). A summation (area under the curve) will be calculated.
