Years ago I went on a keto diet for almost a year to stop progression of diabetes. It worked, years later my A1C1 is good, insulin is good and fasting glucose.
Well, ever since that. My brain never recouped. I forget alot, my witty comebacks are gone, etc. I talked to my dr about this at the time and she didn't seem to be concerned since eventually I remember. Anyone else have this? Years later I still miss my once sharp brain.
