Rocky-inspired Philadelphian hey_suburbia decided to put Wii Sports to the diet test back in early December. The idea was to see if the game could help him shed unwanted pounds when played with full, exaggerated movements. He continued his normal activity and eating habits only adding 30 minutes of Wii Sports to his daily routine. The results after six weeks? He lost 9 pounds.

He writes: "According to The American Council on Exercise, I went from being in the 'acceptable' category to being in the 'fitness' category... I lost almost 2% of my body fat by doing nothing more than playing [motion] video games for an extra 30 minutes everyday."

In terms of which games produced the greatest amount of weight loss, Wii Boxing burned an impressive 125 calories/half hour followed by Tennis at 92 calories/half hour and Bowling at 77 calories/half hour. A lot of husky kids just got some powerful ammunition in convincing mom to buy them a Wii.
