I don’t know how different diets affect basal rates. I am looking for a diet that works well for type 1s as well. I have found little information from my CDE. What I do know is that when I was diagnosed 4 1/2 years ago, I had to make several adjustments upward on my basal rates due to the ending of my honeymoon. I still do have to adjust my basals back and forth a bit, but the 6-12 month after diagnosis time was very active with basal increases. My insulin needs really changed during that time.
May not be what you are experiencing, but I think it’s worth considering.
I hope that helps.
