Hi JJ,
Fasting heals everything. Your body knows what to do when you abstain from food. All your organs should perform to its fullest capacity if you do fasting correctly. If you are worried about DKA you should know that it is not very easy to get into DKA.
If you want to check your Ketones during a fast, you can buy Ketone strips for urine.
Best wishes.
