my endo told me nothing about carbs. She did put me on Lantus 10un at first. Then bumped it up to 17 in 3 months. Then awhile ago she bumped it up to 25. With my last app in July she moved it down to 20.
My low carb 60 per day came from my Registered Dietitian. Then of course on my own. I googled low carbs dieting.
Lots of bad info out there. I think common sense kicks in at some point & after testing , you can see for yourself how your own system works.
