ATLANTA – Drunks swimming in gin, smokers in body bags and dopers living with their parents deep into adulthood. Those are among the public service ads shown in the past.

But the government’s new batch of obesity spots declines even to show a fat person, let alone wag a finger for gluttony or sloth.

No one is advocating public service announcements that ridicule fat people; experts say such spots would do more harm than good. But critics complain that the three new spots premiering this month are a wimpy attack on the costly and deadly explosion of obesity in America.

“It’s so namby-pamby I think people will shrug it off,” said Michael Jacobson of the Center for Science in the Public Interest, a Washington-based advocacy organization.

The three new spots are the latest in a series created by the Ad Council and the U.S. Department of Health and Human Services, which try to tackle the nation’s obesity problem with ads that encourage healthy snacking and taking the stairs.
