Summary
Adding calorie recommendations to restaurant menus did not reduce food purchases. Instead, recommendations may have slightly increased calorie intake by encouraging the purchase of higher-calorie entrées.
Area of Science:
- Public Health Nutrition
- Behavioral Economics
- Obesity Prevention
Background:
- Mandatory calorie posting on chain restaurant menus was implemented in New York City in 2008.
- The effectiveness of supplemental calorie recommendations (daily or per-meal) alongside posted information is not well understood.
Purpose of the Study:
- To examine the impact of adding daily or per-meal calorie recommendations to mandated menu calorie information on food purchases.
- To assess whether these recommendations influence calorie consumption among chain restaurant patrons.
Main Methods:
- A randomized controlled trial was conducted before and after the implementation of menu calorie posting in two McDonald's locations.
- Adult lunchtime customers (n=1121) were assigned to receive daily, per-meal, or no calorie recommendations.
- Food purchases (receipts) and survey responses were collected; data were analyzed using regression models.
Main Results:
- Posting calorie benchmarks alone had no direct impact on food purchases.
- Calorie recommendations did not moderate the effect of calorie labels.
- Recommendations were associated with a slight increase in calorie intake, driven by higher-calorie entrée purchases.
Conclusions:
- The findings do not support using calorie recommendations to enhance the impact of posted calorie information.
- Calorie recommendations may not be an effective strategy for reducing restaurant-associated calorie consumption or combating obesity.

Factorial Design
Factorial Analysis is an experimental design that applies Analysis of Variance (ANOVA) statistical procedures to examine a change in a dependent variable due to more than one independent variable, also known as factors. Changes in worker productivity can be reasoned, for example, to be influenced by salary and other conditions, such as skill level. One way to test this hypothesis is by categorizing salary into three levels (low, moderate, and high) and skills sets into two levels (entry level...
Energy Balance
The human body gets energy from the three macronutrients: carbohydrates, proteins, and fats. Energy is released when the chemical bonds in the organic compounds present in the food are broken down. The energy content of food is measured in kilocalories (kcal), defined as the amount of heat required to raise the temperature of one kilogram of water by one degree Celsius. This value is determined by measuring the temperature change of the water surrounding a calorimeter after the complete...
Regulation of Food Intake
Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...
