I'm not surprised that people are saying "been there, done that". That's the way American culture is -- one fad after another. Interest in LC probably reached a peak when all the restaurants started offering LC options but sooner or later interest in LC will taper off. There won't be so many LC products available and LC will get less publicity. But many, many people have been successful at losing weight and KEEPING IT OFF. I may lose a few more pounds but even if I don't I feel great and will never go back to eating a high carb diet. There are so many benefits beyond losing weight.
