no. its a scam and a waste of money. its really fun to play but doesnt help at all!

If he does it a lot and sticks to it, then yes. However, I'd say just go out running, stretching, etc, since that's essentially all you do with the Wii Fit.

It is hard to answer that question, he would need a lot of commitment, work out everyday. The Ea sports active is a pretty good game and makes you sweat!!! I think it is better than the Wii fit for losing weight... I bought the Wii to stay in shape but I am not very commited with playing it everyday (my weight is the same for the past month, but I haven't played it everyday... at least I haven't gained either lol).Your friend is too young and should be riding a bike, playing sports, and diet is also very important. But he does need to lose weight and if he want to try the Wii, he will have to do it everyday plus diet... the Wii alone won't help him.I own Wii fit and Ea sports
