Do you take supplements? I'm worried that fasting might cause my body to use all its micronutrients and me ending up with health issues because of it.

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.
