Um, I'm not on any specific diet, per se...but I'm thinking about following TSP II. There is plenty of info about it on this site (see the "Which low-carb plan is right for me" link at the right of the page). Basically, it is fairly LC (but not supposed to be ketogenic) and preaches all natural foods--no artificial sweeteners, no dietary chemicals, minimal "man-made" foods, etc. The specifics for carbohydrates vary based on which category you fit.
