IANAD, but I suspect you’re wrong. It’s the high glucose levels which play havoc with the kidneys, and reducing them is more important than eating less protein.
False dichotomy. It's not an either-or. Reducing both is important with damaged kidneys. There are other ways to reduce glucose levels besides the Atkins diet, ways that don't poison the kidneys with protein by-products. The Atkins diet is for healthy kidneys only.
BTW, my source is a dietitian at a kidney transplant center. What's yours?
