Adherence

Providing calorie labeling on fast food menus has no significant effect on the energy content of meals ordered or consumed by adolescents and adults.

Adding calorie counts to fast food menus does not reliably lead to lower calorie orders in a single visit. Consumers often do not notice the labels, and even when they do, it does not change their choices. To be effective, labeling must be paired with education on how to interpret and use that information.
