As to evidence about long term diet and T1there isn't much but the available evidence points to better HbA1cs in those T1s whose diets is higher in carbohydrate and fibre and lower in saturated fats
The long term DCCT ( there are limitations to the evidence ) found that
Among intensively treated patients with type 1 diabetes, diets higher in fat and saturated fat and lower in carbohydrate are associated with worse glycemic control, independent of exercise and BMI.

similarly higher fat diets (and smoking) were associated with greater progression of retinopathy. HIgher fibre/carb/protein were inversely correlated (ie associated with slower progression.) As was calories , this was indirect, those who ate higher carbs/protein tended to eat fewer calories: See table 6.

I don't disagree with these findings, but I still maintain that LCHF is much healthier.
It is more difficult for type 1's for a few reasons
- carbohydrate behaviour is farily well known. Most of us know our carb ratios and can easily treat a new food. How many know the total available glucose (TAG) in a hamburger or a cup of cream? I don't, and I've been doing this awhile. If I've lost you already, 58% of protein and 10% of fats are supposed to convert to carbs via gluconeogenesis and from the glycerides in fat.
- many protein products aren't labled, again, how much protein in that steak? Guidelines suck.
- how fast does your protein convert to glucose? Longer than carbs. How long does it sustain?
- how does food quantity affect your BGs? With LCHF my plate sizes can get big. It's often very difficult to estimate the glucagon dump I'll get from simply shoving something into my gut.
- I often skip meaks -- it's called fasting, something I can easily do on LCHF. But the following meal can be h e double hockey sticks due to built up glucagon stores. I can count on a 2x bolus 90% of the time, but if it doesn't raise like I expect ... here we go, Roller coaster time.
My own A1C has risen, but my weight is down and my energy and health are up.
