I am not a doctor. May I refer you to the following paper?

https://www.ncbi.nlm.nih.gov/pubmed/6859052 "Vigorous supplementation of a hypocaloric diet prevents cardiac arrhythmias and mineral depletion."

I wrote a comment a few months ago on fasting supplementation you may find interesting. https://news.ycombinator.com/item?id=12455415

Also seconding the recommendations to talk to a doctor before you do anything. I know that usually goes without saying, but it deserves emphasis given the article is about diabetes. As the current top comment points out, fasting can be very dangerous for diabetics.

Oddly enough I an a doctor of sorts - qualified in medicine 25 years ago, but left immediately to do other things. Thanks for the link. I'm pretty sure I'm not hypocaloric. I make sure I eat enough during the 9 out of 14 days on which I eat, and I haven't lost weight. And yes, none of my comments refer to diabetes.
