Well! I couldn't find the thread where I was talking to someone about CKD when I was concerned about the LCHF diet and the effect that might have on my one remaining kidney. Since I changed my diet, my kidney function (GFR) went up from 54 to 57. I had some more blood test results yesterday and it has now gone up to 63! Above 60 is deemed to be grade 2 kidney disease so I have now moved away from grade 3. This is wonderful news for me and proof that my diet is doing something miraculous to my kidney function.
