Not for me
I rely totally on injected insulin and about six trillions factors affect how this goes so it pretty much settles where it wants!! :lol: I know where I LIKE to be (5's will do) but unless a T1 is very low carb then its hard not to rise beyond what you are seeing even with insulin.Not impossible, but less likely. Ironically (and cruelly!) eating a lower carb diet seems to train your body to convert even protein for glucose and although my nurses say not to count fats or protein when dosing, I do. A few slices of cold meat/cheese will see my bg rise without exception
I can eat the same food two days in a row, with the same fasting blood sugar, with the same insulin doses and get completely different results so not set point for me I'm afraid
