Comparing Calories at Fast Food Restaurants
An observational study of Obesity, run by University of California, Los Angeles at 1 site in United States.
Trial summary
Rating systems are intended to guide consumer choices. This project will determine if a previously developed scale that evaluates the "healthiness" of a restaurant is correlated with the actual choices consumers make when they patronize the restaurants. Read more about this study

About this study
Official title: Rating Fast Food on Healthiness
Rating systems are intended to guide consumer choices. This project will determine if a previously developed scale that evaluates the "healthiness" of a restaurant is correlated with the actual choices consumers make when they patronize the restaurants. The study will also assess whether a restaurant marketed as "healthy" (Subway) rates higher on this scale than another restaurant that makes no such claims (McDonald's). Finally, the investigators will compare the calorie purchases from these two restaurants among youths and their families who eat at each of the restaurants.
