During the fasting period, your eating pattern may be very different compared to normal. However, it is important to keep to a balanced way of eating, including food from all of the food groups and not to eat excessively. In Islam, food is associated with one’s relationship with God.
If you have diabetes and are fasting, it is a good idea to include more slowly absorbed foods (that have a lower glycaemic index) such as, basmati rice, pitta bread, chapattis and dhal just before you begin the fast. Choosing these types foods will help to fill you up and keep your blood glucose levels more even during the course of the fast. Fruits, vegetables and salad should also be included.
When you break the fast, only have small quantities of sugary 
and fatty foods such as Indian sweets, cakes, samosas and puris, as too many can make you gain weight. Use less oil in cooking and try grilling, baking or dry frying food using a non-stick pan.
Additionally, drink plenty of sugar-free and decaffeinated drinks to avoid dehydration, eg fizzy drinks, squashes, fruit juice, water or milky drinks. If you like sweet drinks then use a sweetener instead of sugar.
