I personally go for the higher grain and don't worry about the carb count.

As more and more "low carb" products come out, I'm more suspect of other additives. Just like when "low fat" came out they started putting in the sugar". I steer clear of additives wherever possible.

The low carb got the weight off. Now that my body is in balance, I have to change how I eat yet again. Ergo, "maintenance". I don't even really think about it as "low carb" maintenance although I do stay relatively low carb. I think of it more as "Educated Maintenance". That really is another learning hurdle that defines "success" in a different way.

P.S. I also believe that another reason so little has been explored/written about maintenance is that low carbers' maintenance plans are going to be quite varied. With some sticking to the low carb bars/products and others going the route of a more weight-watchers type program, etc, etc.
