I've had my Wii Fit now for almost a month (it was released in April here in Europe). I know it's not directly related to food, but since a lot of people who visit Just Hungry are interested in fitness and weight loss, I thought I'd share my thoughts about it after using it for some time, especially since it just became available this week in the U.S. (Besides, way more people are likely to read it here than on my sporadically updated personal blog.)
Incidentally, I've written about the Wii as a fitness device previously on my personal blog, focusing on Wii Sports. In a nutshell I was not convinced that playing Wii Sports would do much to improve your fitness.
So, what about Wii Fit then?
