I also am very grateful for Wii Fit. I am 20 years old and a little on the scrawny side (my BMI is just in the underweight range according to Wii Fit) and it has helped me a lot in my aim to gain a bit of muscle. I have started eating 3 meals a day again, which I often missed out on, and this is because i observed that when I skipped a meal I lost weight. I have mostly been focussing on Balance games, and have dramatically improved my balance.
well, it's not technically balance that improves when you play Wii Fit, it's the strength of the muscles in your feet and ankles
