Sponsor's own description

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.
