Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Educational Messaging
Whey protein beverage and pea protein beverages administered in a randomized order with a one- to two-week washout period between beverages.
Dietary supplement: Whey Protein Beverage
Beverage administered and postprandial appetite assessed for 2 hours followed by 1 hour monitoring of food intake from ad libitum snack tray.
Dietary supplement: Pea Protein Beverage
Beverage administered and postprandial appetite assessed for 2 hours followed by 1 hour monitoring of food intake from ad libitum snack tray.
Behavioral: Snack Tray Choices
Items were selected from a snack tray filled with healthy and unhealthy snacks in order to determine if educational messaging influenced snack choices. Shack choices wre recorded on a check list by a third party observer.
Active Comparator: No Messaging
