This book is full of explanations about why you haven't decided to be serious about losing weight. It documents the excuses we all seem to cling to, and it gives some practical advice on how to overcome the excuses and get busy. I was disappointed that "flipping the switch" was in my mind. I was hoping for more of a metabolic "switch" that I could flip after reading the book, to get past a plateau in my weight loss goal.
I do think this book would be good for someone who is just starting to think about taking their weight problem seriously and who has no idea how to eat healthy. There is a 7 day "jump start" menu that I think you could probably follow for several weeks and lose weight with balanced meals.
