If you eat very low carb that puts you in ketosis, I have found that for me, Its almost impossible to have a BG rise, despite the amount of protein I eat.
Chasing low insulin levels (by making sure I stay in Ketosis) has also been instrumental in resolving my Dawn Phenomenon.
Its really made things simple and easy by emphasising my insulin levels which I keep low by staying in Ketosis.
I am type2 and control the condition with lifestyle choices of diet and exercise alone.
