I’m not a doctor so don’t take this as med advice. Keto and intermittent fasting dropped my a1c from 7:2 to 5.4. was taking Metformin at one time, which I came off of. Metformin is a good drug, I believe, and would consider it just for anti-aging but if you can get your blood sugar and more importantly restore insulin sensitivity, in my opinion that is much better. In My non-medically trained, opinion.I will receive the official Type 2 Diabetes diagnosis tomorrow afternoon. I got the lab results last week confirming. I hope that my doc will put me on metformin as it may be easier to tolerate.
