Somewhere, Ronald McDonald is quaking in his boots. Massachusetts has just passed the nation’s toughest statewide restaurant labeling laws—requiring chain restaurants like McDonald’s and Taco Bell to post calorie counts for their food on all menus. The law comes in response to a state study that found more than half of the adults living in Massachusetts are obese. But will the reminder that a Big Mac is unhealthful be enough to deter fast food lovers? New York City enacted similar a similar law last year, and The Daily Beast can report that there are still overweight people living in the area.
