Different people will find different approaches that work for them, but in general, keeping carbs low is a good idea.
For those who are scientifically inclined or "just want to know", the technology of CGM (Continuous Glucose Monitoring), can be extremely enlightening. You get instant feedback of how high your glucose levels go when eating certain foods. You also see how long it takes your body to clear that glucose which gives you a good idea of how insulin resistant you might be.
Absolutely fascinating for nerds like myself! It's a bit pricey unless you can convince your insurance to pay for it, but if you do care about your glucose metabolism this is money extremely well spent. You would be surprised how many foods (especially processed foods, of course) will cause a glucose spike. Even some that are labelled "gluten free", "keto" low carb", etc. I'm not diabetic, but I do try to keep a low glucose diet and after a few years of experimenting, I have pretty much found what works for me and what doesn't. That said, I still double-check with a CGM for a month or two every now and then - and STILL find the occasional surprise!
I agree about using a Continuous Glucose Monitor as a great management tool. The before and after eating something is sometimes eye opening.
When I'm having a "low day" is when I can step up to something with more carbs.
Even if your insurance won't pay for the replacement modules, it's worth paying for out of your pocket.
