I stick around the lowcarbers forum for a variety of reasons:

a) I love forums
b) I am in this for the health reasons and I find the studies and links posted and discussed here are priceless.
c) I am constantly re-inspired by other peoples weight loss journeys and successes
d) recipes, food ideas, info on sweeteners (I still use them and am on the fence about breaking that habit) - all good

As I mentioned before, I find maintenance to be an active and conscious excersise (probably since I am fairly new at it), so I still need a community like this one!
