I've been using 'The Zone' for about a month now. I have just started 'The Soy Zone'. I really like it a lot and am losing. I'm not a fan of meat, but do eat it at times. With the soy zone, I don't have to worry about eating meat if I don't want to. I didn't realise I'm not 'doing it by the book' until today. I don't subtract the fiber and in doing so, my Ecc's stay under 100 and that would make it a moderate to low carb diet, I beleive.
