Hi! Thank you for your questions, and I certainly can understand your concern for your dear family member.
Fasting with diabetes can be beneficial but also has to be done with much caution, depending on the particular person's state of health.
I highly recommend you visit our Fasting Diabetes page to get more information, and gauge your family member's information based on the questionnaire in that page.
You can find that page at http://www.fitnessthroughfasting.com/fasting-insulin.html
I wish you all the best and let me know what you decide either way.
It also would not be a bad idea for her to visit a holistic medicine doctor so he or she can perform a full examination and determine what is the best course of action for your dear family member.
