This book is amazing. I know quite a bit about weight loss but this book makes it so simple to understand. You can work out exactly how much you need to eat based on your metabolic rate and it also helps you figure out what sort of oxidizer you are. This really helps you feel focused and the Science section is wonderful. It makes the maths of losing weight so simple and easy to understand. I love Jillian Michaels and ever since I saw her on the Biggest Loser I knew she had the correct attitude for weight loss that lasts. I've lost another 30 lbs already thanks to this book and I highly recommend it.
Even if you already have a clear idea of what you need to do to lose weight, this book will help you focus your energy where it's needed most. The exercises in the back are worth a look and although some of them require gym equipment, you can do most of it at home. I have all three of her DVDs (burn fat, boost metabolism; 30 day shred; no more trouble zones) and I'd recommend all of them too. If you aren't afraid to work for your weight loss goal then I'd highly recommend all of her products!
