Query: Worked for me!

I used this book (it was my wife's), and although its from a women's website, I found the approaches easy and practical. We followed this book together for about 5 weeks -- I lost about 15 pounds and she lost about 10. I was about 215 before and came out about 200. Now I'm a 34 and was 36. That was 3 months ago and no change yet. Try it - it works.
