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.

Detailed description

Participants will complete 4 different snack patterns. Each pattern will include 3 nonconsecutive weekdays (i.e., Monday/Wednesday/Friday; Tuesday/Thursday/Monday, etc.). The snack patterns will be performed at home/work. The first pattern will simply be a measurement of typical snack habits. For each of the 3 days, the participant will enter all foods and beverages consumed using the online program, Automated Self-Administered 24-Hour Dietary Assessment Tool (ASA-24). For the other 3 patterns, different snack packouts will be provided to the participant for 3 nonconsecutive weekdays/pattern. The only difference between the packouts is the type of foods provided. The packouts contain commercially available foods commonly eaten by people who snack. Following lunch, the participant will be permitted to eat as much or as little as he/she chooses from the packout until going to bed. Beverages will not be provided and the participant could drink whatever he/she typically consumes. For all patterns, the participant will be provided with a standardized breakfast, lunch, and dinner to consume at home/work for each of the 3 days/pattern.

Type	Name	Description
BEHAVIORAL	Packout	Each packout provided during 3 of the 4 snack patterns will contain a variety of foods to be consumed, ad libitum, throughout the remainder of the day following the standardized lunch. There are 3 different packouts that will be provided for 3 nonconsecutive weekdays (for a total of 9 packouts). Each packout contains the same calories and types of foods. However, they differ in packaging size and variety.
