On a keto diet, one can attain < 20g carbs per day with some struggle but to cut it out entirely is really hard without missing some other essential nutrients - because at least some carbs tag along with other things.
If you refuse to consign yourself to the fate that most MD's in the US describe for their diabetic patients (mine told me, "there's nothing you can do to improve it, other than some exercise, take the medicine, annual check ups, and then hope there aren't complications as you age"...I got another general practitioner), then self-support groups like this are the only way to go to find what works for you, IMHO. The Reddit group is also helpful when starting out, but I found them not as hardcore about control as I wanted, which I found in some members of the DD group.
