1. Calorie-count wake-up call
This year, New York became the first U.S. city to require restaurant chains with 15 or more locations to post the calories in menu items. For example, a Big Mac with medium fries and a medium soda contains 1,130 calories.
Will people shy from the 900-calorie burrito in favor of the 500-calorie version? Some probably will, if they haven't already. For most, the calorie postings will eventually seem invisible, like the mandatory choking-first-aid posters all NYC restaurants are also required to display.
