Study Summary
The investigators propose a randomized snack study in normal to obese adults that will test whether snack size, choice, or variety has an influence on daily snack intake. Aim 1: To validate the in-house packout methodology with 3-day dietary recalls. Aim 2: To examine whether snack variety or snack package size will influence free-living snacking behavior. Aim 3: To identify whether a correlation exists between mindful eating and free-living snacking behavior.
Primary Outcome
Free-living energy intake will be assessed on the three testing days of each testing arm. For the control testing days, the participant will be provided with a standardized breakfast, lunch, and dinner, and will be required to log any snacks consumed on the Automated Self-Administered Recall System (ASA24). For each pack-out testing day, the participant will be provided a standardized breakfast, lunch, and dinner, as well as an excess of snacks to consume, ad libitum, throughout the day. All foo
