A new study finds New York City's law requiring restaurant chains to post calories on menus doesn't change the eating habits of low-income people.
The study tracked customers at McDonald's, Wendy's, Burger King and Kentucky Fried Chicken in poor New York City neighborhoods with high obesity rates.
Half of customers noticed calorie counts. Twenty-eight percent of those said postings had influenced what they ordered. Nine out of 10 of those said they'd made healthier choices as a result.
But New York University and Yale researchers say receipts showed people had ordered slightly more calories than the typical customer before the law went into effect in July 2008, according to the Associated Press' report.
