A physicians' group campaigning against McDonald's fast food offerings says that four Houston TV stations have refused to run its advertisement equating cheeseburgers with heart disease and death. The advertisement from Physicians Committee for Responsible Medicine, titled "Consequences," displays a doctor and a weeping woman standing over a corpse clutching a cheeseburger in its right hand. The 30-second spot ends with a picture of the McDonald's logo, the words "I was lovin' it," a parody of the company's "I'm lovin' it" slogan, and the voiceover, "High cholesterol, high blood pressure, heart attacks. Tonight, make it vegetarian." Susan Levin, director of nutrition of education for the Washington, D.C., nonprofit, said all four of Houston's major network affiliates turned down "Consequences," which she said has aired in Chicago and Washington and was rejected by stations in Miami. The group was prepared to pay $5,000 to air the ad locally. Houston was selected for the campaign, the group said, because of its market size, its reputation as having one of the nation's highest obesity rates and because it has 149 McDonald's outlets, more than any city in the nation other than New York. The "Consequences" spot has been viewed more than 1.1 million times on the group's YouTube site.
