I would focus more on what treatment is best for you.
Do you do keto diet to try to control bg? Or would you prefer non-keto with insulin or type 2 meds? (Having a c-peptide test while doing “normal” diet may be more helpful.) Or is your goal to postpone any/all meds as long as possible, so you remain on keto.
As @terry suggested, you will find great documentation by @Melitta.
