No, it's not the Onion. I swear I'm not making this up. The Reuters headline:

McDonald's Launches Anti-Obesity Campaign

and this, from the story:

McDonald's U.S. Marketing Director Alex Conti said the company was launching a new Web site to go along with its "Go Active" adult Happy Meals, which include a salad, bottled water and a pedometer to encourage walking.

The Web site, filled with pictures of celebrity athletes including basketball star Yao Ming, allows users to create fitness plans and track workouts.

Yao will presumably lecture us on the important obesity-avoiding benefits of being 7'2".
