This book is about how to lose weight by eating foods with a low glycemic index. The book is written clearly, and describes the diet in simple terms with a few recipes and lots of hints and good ideas. If I were going to go on a diet I would go on something like this, except that I love bread far too much to give it up to the extent that the diet requires. I'd rather be fat than give up bread.
I like that the book is written by a Canadian doctor and is clearly for a Canadian audience (there are other editions for other parts of the world); he refers to Canadian brands and discusses the difficulty in getting exercise when it's snowy and miserable half the year.
