I have searched for info on the Ketogenic diet for T1 Diabetes, without success. I think this is a shame; my personal experience is that the effects of the Ketogenic diet have been extremely positive for my Diabetes. (Stabilised blood-sugars; no Hypoglycemia).
I have a large Guide Book for the Ketogenic diet, in the format of a PDF file. I'd be happy to send it to you if you are interested. It does not contain "plans", sample menus etc.. It goes into a lot of detail regarding the physiological effects of the diet on the body and brain.
