High Caloric Restaurant Meals Are Not Cause Of Obesity

Although people do eat more when they eat in restaurants, Matsa and Anderson found that diners compensate for those typically highly caloric meals by curtailing what they eat at home during the rest of the day.

From "Are Restaurants Really Supersizing America? Restricting restaurant meals may not trim Americans’ expanding waistlines" based on the Research of Michael Anderson And David A. Matsa on Kellogg Insight.

It is also unlikely that posting calorie counts of foods at stores and restaurants will help fight obesity. People keep their daily total calorie consumption relatively constant.
