As someone with a fasting glucose of 95-99 (my GP isn't concerned, I'm not a diabetic), I wonder why would you want to reduce fasting glucose if it's not even in the prediabetic range?
This study showed progressively increasing risk of heart disease in men with FBG levels above 85 mg/dL, as compared to those with FBG levels of 81 mg/dL or lower: https://www.ncbi.nlm.nih.gov/pubmed/16207847
In the 30 days since I completed the fast, my fasting blood glucose has dropped from ~80-90 down to 65-75.
I'm concerned about the accuracy of my Freestyle Libre, but it was previously consistent with professional labs.
Anyway, a long term fast like the one I did may help improve your insulin resistance; it seems it did for me.
