Lets be clear about this, the most important levels for T2D are the spike levels - the difference between pre-meal Blood Glucose and the Blood Glucose 2hrs after first bite. These are the ones that you get under control immediately with ow Carb and BG testing.
This means that almost immediately you are no longer damaging your body.
- OK, it's nice to also have a low fasting BG (no Dawn Phenomenon), but you can have a normal (not even pre-diabetic) HbA1C level yet still get some DP.
