NYC pioneered a project where fast food chains were required to post the calorie count of individual food items right next to their listing on the menu. However, a group of researchers found that while 9 out of 10 people have said that it has influenced them to make healthier choices about what they purchase, they "found that people had, in fact, ordered slightly more calories than the typical customer had before the labeling law went into effect, in July 2008.

I wonder if this is because of the way the information is presented and not so much because people do not care about making a healthier choice.
