Studies show that despite the mandates that fast food and restaurants list calorie counts for their food items, people are not eating any less and some surveys show that it prompts people to eat more.
An article in Time poses a question about how listing the requirements to burn off those calories would impact eating behavior.
The article sites a study conducted by Dr. Meena Shah and Ashlei James from Texas Christian University, where they replaced the calorie count with the number of minutes of brisk walking a person would need to complete in order to burn the calories that they are choosing to eat.
They chose this activity specifically because it's an activity most people are capable of doing. Then the researchers completed the study on 300 men and women (ages 18-30) because their activity level is higher and they could relate to the activity listed more.
The study found that participants who were provided the walking information, chose to order and eat lower calorie food items.
