Well, it's official. Beginning today, all restaurant chains in the U.S. with 20 or more locations must post calories on menus or menu boards.
When Congress passed the Affordable Care Act, back in 2010, the federal calorie posting mandate was born.
Many chains, including McDonald's, Panera and Starbucks, began posting calories several years back. But the proposed regulations hit several snags as industry groups lobbied for changes. Now, there's no escaping them.
