Dan, not sure where you are going with this but the type 1 treatment in the 1920s was total carb restriction and extreme calorie restriction, and it worked to slow (not stop) the destruction the disease caused. Once George Banting "discovered" insulin it was huge. There is a story in "The Discovery of Insulin" by Bliss about Banting's patients waiting for his return from a meeting to learn whether there would be enough insulin for them. It will absolutely rip your heart out to read it. In this era where insulin is widely available, it is different, but to read it you go back in time to the immediacy of their experience and it is very enlightening, as I am sure you understand.

In 2011, if there is a problem with diabetes, then the best information I have is that a reduced carbohydrate diet helps, doesn't fix but helps. Works best with DM2, less so with DM1 but still helps.

The biggest problem with insulin is that almost everybody who uses it gains weight over the years which makes the weight gain worse, and the insulin requirement grows.

The common path is to cut the carbs. No downside except missing cake. YMMV.

P.S. Thanks for the use of the lighter!
