Do Calorie Counts on Menus Help You Eat Less?

What visible calories change

Most people do not know how many calories a restaurant dish contains before they order. A number on the menu makes it possible to compare options of similar price and size. The decision can change before the food ever reaches the table.

Labeling does not alter the makeup of a dish once it has been chosen. Its effect depends on the customer's attention, how clearly the number is presented, and whether a suitable alternative exists.

What the Cochrane review found

The updated Cochrane reviewincluded 25 studies of calorie labeling on food and drinks. Most of the data concerned the selection and purchase of products. There was less evidence on actual consumption. The studies were carried out in stores, restaurants, and experimental settings.

For a typical 600-kilocalorie meal, labeling reduced the energy selected by about 11 kilocalories. The effect was small, but its direction stayed consistent.

In studies of actual consumption, the difference was about 35 kilocalories. Confidence in that estimate was lower because there were fewer trials. The data on alcoholic drinks remained uncertain.

How to use the number on the menu

Compare dishes of the same type, then check the protein, the vegetables, and the volume. The lowest-calorie option may turn out to be not very filling. The choice should lower total calories and still leave you reasonably full.

Labeling is useful when you already have a criterion in mind. One example is choosing between two breakfasts with similar ingredients and different calorie counts.

Where labeling falls short

The number for one dish does not account for the drink, the appetizer, the sauce, and the dessert. The calories in a portion can also differ from the laboratory estimate because of how it is prepared. Labeling reduces uncertainty, but the actual portion can still deviate from the stated value.

With an eating disorder, calorie numbers can heighten anxiety, so treatment remains the priority. The number on the menu tells you what a dish costs in calories. It does not cancel the decision to order a second helping.
