If you decide to fast you consulting with your doctor and keep in mind:
•   If you are taking insulin, you will require less insulin before the start of the fast 
•   The type of insulin may also need changing from your usual type 
•   Pre-mixed insulin is not recommended during fasting
•   Before starting the fast, you should include more slowly absorbed food (low GI), such as rice, pitta bread and dhal, in your meal, along with fruit and vegetables 
•   Check your blood glucose levels more often than you normally would 
•   When you break the fast, have only small quantities food, and avoid only eating sweet or fatty foods
•   Try to eat just before sunrise, when you commence the next day’s fast
•   At the end of fasting you should drink plenty of sugar-free and decaffeinated fluids to avoid being dehydrated.
