Unless you are having problems with chronic UTI, the studies show SGLT inhibitors are protective of the kidneys. FWIW I've been on them for a couple years and haver not had any side effects other than some initial weight loss. I know that's just one data point.
VERY rare cases it has been shown to cause kidney injuries. What i am trying to tell you is from someone who had experience with it. You can have the same effects that SGLT inh have without the drug side effects whatever they might be with a low card diet.
