I was on the Keto diet for 4 months but have never really had any problem with my voice that I remember, so I have no change to report in that regard. I did gain a tremendous amount of energy and of course lost weight. I also feel it was instrumental in reducing my inflammation.
Why you left that
I had 2 reasons, my Dr requested I not stay on it and I got a pinched nerve in my neck that was so severe I could not function on my own, was barely able to eat anything, much less cook for myself. I am doing a maintenance program of AIP/Keto with some additional carbs to maintain weight and reduce food sensitivities that cause inflammation.
