Making Calories Count: Information Format and Food Choice

April 11, 2017 updated by: University of Pennsylvania

The purpose of the study is to better understand how individuals make decisions regarding the meals they order. Participants' ordering decisions at lunchtime at a chain restaurant will be recorded over several weeks to study ordering habits over time. Lunch menus will be provided by the study, and the menu format will vary the way in which information on caloric content is displayed.

The impact of different labeling formats on total calories in the chosen meal will be assessed.
