Query: No kidding, this is old news...

This book was a waste of money for me. No kidding women need to exercise to keep the fat off and your matabolism up! Everything she said I knew 5 years ago. If you don't know anything at all about nutrition, this book may be informative, but there are better ones out there. Try Atkins, he knew what he was talking about. After 4.5 months after pregnancy I have lost 45lbs already. Good luck.
