I agree with the person who tried this diet for 7 weeks, lost 5 lbs. the first week, then nothing else happened. That's exactly what happened to me! I started on January 18th (nine weeks ago) and I finally quit in disgust a few days ago. What WAS true is that you lose your food cravings during the day (I stuck to protein and vegetables/salad during breakfast and lunch.) What is NOT TRUE is that your daily reward meal (usually at dinner) will enable you to lose weight. In other words, my food craving stopped, but I didn't lose weight! As a matter of fact, I started gaining weight in weeks two, three and four before again reversing. I agree in principle with everything said in this book (including the need to regulate insulin/blood sugar.) And if your goal is WEIGHT MAINTENANCE while eating anything you want (including pizza, chocolate, ice cream, and pasta) on a daily basis, then this book is for you. But you will NEVER NEVER NEVER lose weight with this.
