Dr. Kaplan's writing is sincere without being condensating. My biggest fear in life was having to quit sugar, and his argument is logical and clear....sugar is addictive and destructive. He illustrates that he doesn't keep sugar in his house, if he doesn't, then why not me??? I have balloned up and down 15-20 lbs. every year like a roller coaster and each time i lose weight it's because I quit sugar, and as soon as I go back, the weight magically appears. Nothing has ever convinced me of my eating disorder than this book. Low carbs as well, and mucho salads. Carbs are a big culprit as well. Kaplan is a happy medium between Fit for Life and Dr. Atkins, both programs which go rather extreme.
