Ad angers McDonald's

In a television advert that could kill your appetite, an overweight, middle-aged man is seen lying dead in a morgue holding a half-eaten hamburger as a woman weeps over the body.

McDonald's ubiquitous golden arches then trace the dead man's feet with the text "I was lovin' it".

A voiceover says, "High cholesterol, high blood pressure, heart attacks. Tonight, make it vegetarian."

Produced by Washington health lobby Physicians' Committee for Responsible Medicine, the commercial is set to be aired in Washington DC during The Daily Show with Jon Stewart.

The ad has enraged McDonald's. "This commercial is outrageous, misleading and unfair to all consumers. McDonald's trusts our customers to put such outlandish propaganda in perspective," spokeswoman Bridget Coffing said.
