@indigo Carbs impact blood sugar, which is important to control for as well, but isn't the real issue, insulin is. Specifically, for Type 2 Diabetics, is that's the body already has too much insulin.
Eating anything (including low-carb food) will cause insulin to spike. The insulin impact of particular types of food has not been studied very much. Fat in its purest form is about the only thing that won't cause a spike.
The only thing guaranteed to not spike insulin? Fasting.
