4.9 is an average blood sugar of 97. Not low at all.
Your doctor is probably assuming that you are achieving such a low A1c by dropping to very low levels and that would be dangerous. Most doctors don’t understand how a diabetic can suddenly achieve and maintain normal, non diabetic blood sugars by eating low carb so when they see improvements such as yours they assume you’re going very low and that’s how you’ve got that A1c.
They will assume you’re running 120-180 or whatever lots of times and dropping by to 50 or whatever so much that your average is then 97. But you’re actually only ranging from 70-110 then you’re actually at a amazingly healthy blood sugar and that’s a stellar A1c!
Congrats!
If you tolerate the metformin maybe take it a bit longer because a “perfect blood sugar” is considered 83. Not that your A1c needs to be that low, but your average is still well above that. Without the metformin it will almost certainly rise a bit.
If anything, maybe just reduce the dosage.

Is your Dr. aware of your diet changes? Do you check your blood sugar daily? I would talk to him about continuing with Metformin. If you have made permanent lifestyle changes you might not need the metformin.

An A1C of 4.9 corresponds to an eAG of 94 mg/dl.

Formula is: 28.7 X A1C - 46.7 = eAG (Estimated Average Glucose)

Does your dr. understand that you are eating low carb and that your BG's are consistent rather than bouncing between too high and too low? Consistent BG at 94 is a non-diabetic level.

FWIW, A1C doesn't exactly correspond to BG as there are other factors that affect A1C. Even when using a CGM nearly 24/7 and seeing BG's in the 80-90 range almost 24/7, I still haven't been able to reach an A1C below 6.7%.

I'm a diabetic whose A1c is finally starting to go down. My last A1c was 7.2, the lowest it has been in a while. My doctor asked if I would consider trying keto. I have checked a couple of sites. It seems like the basic thing about keto is cutting back on carbs. This seems like a hard thing to do cause I LOVE carbs. Any suggestions on how to start keto??

Yes, there is tons of information about starting a keto diet. Are you a type 1 or type 2? Are you taking insulin? There may be confounding factors for you that don't apply to non-diabetics, and those factors depend heavily on how you are treating your diabetes today.

Keep in mind also that A1C may end up higher than average BG would predict. This is because A1C is based on measuring the impact of glucose carried by blood. As your red blood cells carry more glucose, there is more of an impact made on those red blood cells - the glucose leaves a "footprint." Usually they say that A1C measures control over about 3 months, which is based on average life of red blood cells. However, a healthier person is going to see red blood cells last longer. As a result, your A1C can be artificially inflated because older RBC's will have just as many "footprints" as younger RBC's with higher average glucose. Just know that even if A1C's don't reach what you would like to see, there may still be improvements happening with blood glucose. Testing BG can be useful to pinpoint that.

For me, it is just a thing like taking my meds. I do it because that is the path to health for me. I have almost completely lost my craving for carbs on this diet. My veggies are leafy greens, broccoli and cauliflower. You can do it.

Be thankful you have a dr. with the sense to know what halts diabetes, you are so lucky that your dr. wants you to go keto.

I used to love my bread, passionately, but I found I liked losing weight, feeling like I could do anything I wanted again physically and knowing I was not going to get diabetes even better than the grains, starchy,and sugary carbs.
When you look at what you can eat, instead of what you should be avoiding, it is a very nice picture.

Check out the Launchpad on this group's web page for all kinds of good info on eating this way and information from those of us who have been down the path.

Here are a couple of places to get meal planners, so you know what to eat

https://files.atkins.com/18-03-Atkins-MealPlan-Foodie-20.pdf Just ignore the snacks that call for shake or bars. I started out with this plan, Super easy to follow. I also used the info on their site to slowly up my carbs after the initial getting started phase. They call it a ladder. It really helped me see what I could keep and what I would need to only use as an occasional treat.

For great graphics of what is good to eat, you can't beat the dietdoctor, there is a 14 day starter plan, the site does have excellent resources that require a small monthly fee, but there is still a ton of info that is free on the site.

Good luck on sorting yourself out.

It took me 8 years to smarten up. Finally took bread out of my diet and i'm seeing great numbers in the morning. It was always close to 10 now in the sixes for the last week of no bread. Darn I should of done that years ago.

Sometimes it takes a while to figure out the details. You have this bit down now!
