Doing a search for something else, certain nutritional supplements, probably. I saw the book on eBay.
Being curious, and trying seriously to lose weight, I looked it up on the internet. I had just started a "fat fast" ketogenic (KD, 5 day) diet to kick off a calorie reduction, and thought that the Shangri-La Diet might just be the help I needed to maintain the current bit of weight loss, plus what I knew I'd lose from doing short term KD, and then continue on SLD to see if it works. I ordered the book from a bookseller on eBay. I received it Friday and read it yesterday -- already having practicing SLD for 1 week, so far.
