Study Summary
The investigators propose a randomized, tightly-controlled breakfast trial in normal to overweight adults that will test whether the consumption of various types of protein-rich meals, containing \~24g of protein, will differentially alter food intake and meal initiation through proposed appetite and satiety mechanisms. Aim 1: To examine whether the consumption of protein-rich meals that vary in protein quality (source) effect: 1. postprandial feelings of hunger, fullness, desire to eat, prospective food consumption 2. postprandial fluctuations in key appetite and satiety hormones 3. eating initiation (i.e., motivation to eat (again)) 4. food cravings Aim 2: To examine whether the consumption of protein-rich meals that vary in protein quality (source) effect: 1. energy intake and food choice within the breakfast meal 2. energy intake and food choice at the next eating occasion 3. energy intake and food choice across the entire day
Primary Outcome
Questionnaires assessing the appetitive sensations of hunger will be completed at specific times throughout each of the the 4-h testing days. The questionnaires contain 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." A summation (area under the curve) will be calculated.
