According to consumerreports.org, while the addition of calorie counts to menus at your favorite restaurants may be the ultimate night out downer—nobody wants to know what that order of nachos will cost you on the treadmill—experts say they actually work.

The latest study conducted by Cornell University researchers showed that seeing calorie counts in black and white lead some people to reconsider their eating options.

Researchers noted that even the chefs at the restaurants at which the data was collected regularly underestimated the calorie counts of their dishes.

Calorie counts worked best to curb appetites when it came to appetizers and entrees.  People ordered food that had roughly 45 fewer calories than those who didn't have access to that information.
