Earlier this month, the  United States Food and Drug Administration implemented a new set of rules requiring restaurants, supermarkets, and convenience stores with 20 or more locations to go public with the calorie counts for standard menu items. These food establishments must now post the calories on overhead display boards, printed menus, and electronic kiosks.

Heath Line recently examined if these rules will make an impact on obesity rates and turned to Cochrane evidence for answers. Read 'Calorie Counts Are Now on Menus Nationwide, But Do They Work?' and learn if calorie counts on menus can change the way we eat.
