Katherine Bauer, a health researcher at Temple's Center for Obesity Research and Education, recently studied the offerings at some of the largest fast-food chains. The restaurants have created healthier options in recent years, but Bauer said the sheer number of options has increased too. "There's a lot of things being advertised and sold to you," she said. "You have to be thoughtful in what you are selecting to ensure that you are not going to end up with a meal that's way over your target calorie intake for the day."
