Lose weight by BREATHING?

This is the strangest concept in weight loss I've ever heard. I know people it worked for them, but soon after I started it, I hurt my back and got out of the habit of using things I learned in Be A Loser. The book is based on the BodyFlex system, and if you have never seen the BodyFlex videos, they are hillarious. So I don't know if this helps you lose weight or not, as I didn't really try it, but I did lose weight with other methods this year!
