Hehe thats a pretty cool experiment Maybe it will inspire more people to buy Wii. However its no magic behind this and it doesnt exactly have anything to do with the Wii. Your just in movement and that increases your metabolism, thats it. Walking 2-3 extra miles each day would probly done the same trick for him.

But hey, walking or playing Wii sports for 30 min each day, what do you choose? Hehe. I'd probly choose walking because of the fresh air, but the Wii is also a good way to do it if you want to get in better shape

I bought a Wii today, so I may try this out.
