I went keto in the same situation Ramgator.....I was on the door of diabetes....and I started the keto diet and reversed all.

My brain, body, joints are about age 35-40 instead of 56.
Zero inflammation in joints....workouts are incredible...life changer...working 13 hours, sleeping 6 hours and it is like
the old days. My mind is clearer, and my memory is pretty good again...and playing guitar is different, too..
