According to a study published in the American Journal of Public Health, mandated calorie counts on fast-food menus have little to no effect on diner's ordering habits. The Daily Mail rehashes the study conducted by Pennsylvania's Carnegie Mellon University, which examined the orders of more than 1,100 McDonald's customers in New York City. Despite posted calorie counts, the majority of McDonald's guests ended up consuming more than the nutritionist-recommended calories per meal of 650 for women and 800 for men. (For reference,
a sole Big Mac clocks in at 550 calories; a medium order of French fries has 380.)
Writes the Daily Mail: "The results suggest that consumers, especially at fast-food venues, tend choose taste, value, and convenience over nutrient content."
