This article examines consumer awareness of calorie information at fast-food restaurant chains in New York City after the introduction of calorie labeling on menus and menu boards. Researchers found that awareness of calorie information increased from pre-enforcement to post-enforcement of the calorie labeling regulation (25% to 64%). Among customers who saw calorie information post-enforcement, 27% of customers said they use the information in making their purchase. The authors conclude that posting information on menu boards increases the number of people who see and use the information.
