I came across an interesting article a few weeks ago that looked at how intermittent fasting can help regenerate pancreatic cells in type 2 diabetes. The study itself is available in the journal cell and there is a link here to the article on the BBC website.

There are many different ways to perform intermittent fasting and its about which way works best for you. You can find more information about this here. 

I'm definitely no expert on the subject but it is an area I have started to read about myself as there are many different benefits to this.
