I suffer from arthritis although it's not horrible most days. But I do find that lc really makes a difference in how often and how sever my pain is. I suspect it must have something to do with the fact that carbs hold water in your body . Without them there is not as much inflammation. But that is just a guess. I have been checking out web sites trying to find the answer but so far all the info I have found just says that the weight loss from lc is what causes the lessening of pain. I'm not convinced that that is all there is.
