A new study released Jan. 6 examined consumer behavior before and after calorie counts were posted, and determined that when restaurants post calories on menu boards, there is a reduction in calories per transaction. Based on transaction data provided by Starbucks, researchers from the Stanford Graduate School of Business found that calorie-posting in New York City in 2008 led to a 6% reduction in calories per transaction. According to the study, beverage choices at Starbucks are unaffected by calorie posting. However, calorie posting leads consumers to buy fewer food items, and to switch to lower calorie food items.
