Many people alter their diets and physical activities during Ramadan. After a daytime food abstinence, over-eating during iftar (breaking fast) is common, with a tendency for sweet food and drinks. On the other hand, most people also tend to conserve energy during the daytime, and become more sedentary.
In general, people with diabetes are advised to consume healthy diet during Ramadan. Food that is rich in fiber tend to improve satiety and have less impact on blood glucose. They are advised not to skip sahur, as this may increase the risk of hypoglycaemia during fasting. Similarly, over-eating and binging during iftar should also be avoided to reduce the risk of hyperglycaemia and weight gain during Ramadan.
Physical activity should remain the same as in non-fasting months, however exercise times may need to be shifted to after iftar, to allow fluid intake after exercise. Strenuous exercises should be avoided during fasting hours. Tarawih prayers, commonly performed by many people during Ramadan, is also considered as part of the physical activities.
