I need to Exorcise...?

Okay so I seriously want to loose weight! So i need to exorcise right? But i don't want to work out in public. And my house is pretty small so i cant get any equipment. But i do have a Wii and a Xbox360 with a kinect and some workout games. So what are some good exercises that will help we loose weight fast? Should i keep using my Consoles with the games everyday?
