Thanks! Reading the abstract it says that they only tested people in stages I-IV of CKD. Since I am stage V I'm not sure how much of this applies to my case. Also a high percentage of the study subjects had diabetes and I don't have diabetes. I have been practicing IF for about the past year or so. Initially my creatinine went up a bit but last time was coming down. I agree that further study is in order. Let me know if you hear of anyone doing such a study. I would be glad to participate.
