Wii Fit, Effective Weight Loss Device?

Nintendo wants to get gamers off their couches — again.

When it introduced Wii Sports in November 2006, hardcore gamers and casual folk grabbed a Wiimote (the Wii’s remote control) to play tennis, baseball and boxing in front of their TVs. These games left many gasping for breath, and some players even shed a few pounds.

Now the Big N is taking the physical video game further with Wii Fit, which is due out in the U.S. on May 19th. The game hit Japan in December, where 1.79 million units were sold as of March 29th, according to vgchartz.com, a website that tracks video game sales. The game is packed with a device called a Wii Balance Board, a scale-like platform that acts as a controller.
