I like Barry Groves Book too Natural Health and Weight Loss. It is enormously readable, published in 2007 and 5 star with only 6 reviews on Amazon. I have not read DoreenT's recommendation of Living the Low Carb Life so can't say anything about it except that she only has over 26,000 more posts than I have...

I think I may run out and get Living the Low Carb Life...
