The whole thing with reviews is that some make them so personal they mean nothing to me. Yours is great because it tells us, short and sweet, why some may find it a great book and others will donate it somewhere.
All self help helps someone. The real questions is, "Is this for me?" A good review of anything from movies to restaurants (aside from bad service is just bad service) will point out who may benefit and who may not.
THIS is how to write a review, boys and girls.
As far as the book, food has not changed much nor has the way the human body uses it. i don't know why people think there will one day be some discovery about food that will make us all thin in a week. One reviewer claimed it was just too simple. Fine, go read some mind boggling research, but it will still come down to the same basic principles.
i haven't bought the book, but i'm about to. From the reviews, it may be the hand i need to hold to learn to live a little differently. Little changes go a long way, but i never travel without a map.
