McDonald's is firing back after a new ad by the Physicians Committee for Responsible Medicine (PCRM) drew a huge response this week from those on both sides of the fast-food/healthy living debate.

The commercial shows an overweight, middle-aged man dead on a mortuary table with a woman weeping over his body, his hand still grasping a half-eaten (presumably McDonald's) hamburger. As the camera circles the scene, it comes to rest on the dead man's feet — with a McDonald's logo superimposed perfectly over them. The words "I was lovin' it" followed by "Tonight, make it vegetarian" come on the screen.

''This commercial is outrageous, misleading and unfair to all consumers," said a McDonald's rep in a statement. "McDonald's trusts our customers to put such outlandish propaganda in perspective, and to make food and lifestyle choices that are right for them.''

According to an analysis by PCRM dietitians, McDonald’s, the world’s largest fast-food chain, serves a long list of high-fat, high-cholesterol items and offers almost no healthful choices. “Our city’s addiction to Big Macs and other high-fat fast food is literally breaking our hearts,” says Dr. Susan Levin, PCRM’s nutrition education director. “It’s time to tackle the district’s heart disease problem head-on. A moratorium on new fast-food restaurants could be a critically important step toward fighting this epidemic.”

The commercial is currently only being shown in the Washington, D.C., area, but may expand nationwide in light of the response. Check it out below:
