In DANDR he goes into detail about the 5 levels , ending with full blown diabetes. Meaning there are steps along this pathway. I took him seriously and started to change my eating immediately as I had been a gestational diabetic.The was my wake up call.

I have a T1 friend, that wears a monior and a pump, and still finger pricks a few times a day. Mostly when a new pump is set up.

We had a member here who would check her sugars to test the effect of a specific food. Eating the same foods for several days, only changing one item like to strawberries or other fruit. Interesting to see not all fruit is the same.
