Interesting. I remember several years ago going out with some friends one of them was a doctor. We were eating at an Italian restaurant. He noticed I asked them to swap the pasta for some green veggies and leave off the bread. He looked at me and said you don't need to lose weight , why are you eating that way. I told him I was diabetic and he responded , " there is no way you can be diabetic". I think there are lots of us thinner diabetics out there. I can't remember ever getting sick with a virus or anything that could have pushed my DNA in that direction. I have 5 siblings and none of them are diabetic. My dad also thin became diabetic at the age of 89 after 15 years on Prednisone. So I am the wierd one. My brother is a research scientist at MIT in Boston and works with DNA and human genome. I'll have to ask him what he thinks. Normally when I ask a science question I get an answer I can't understand.
