The prescribed fast of Muslims is different from the many “Diet Plans” because it has beneficial features of both plans. Its unique medical benefits are due to the following factors: 1. As compared to other diet plans, fasting in Ramadan does not cause malnutrition or inadequate calorie intake since there is no restriction on the type or amount of food intake before beginning the fast or upon ending the fast at sunset. This was confirmed by M.M. Hussaini in 1974, when he conducted dietary analysis of Muslim students at the University of North Dakota, State University at Fargo during Ramadan. He concluded that calorie intake of Muslim students during fasting was at two-thirds of NCR-RDA. 2. Fasting in Ramadan is voluntarily undertaken. It is not a prescribed imposition from a physician. In the hypothalamus part of the brain there is a center called “lipostat” which controls the body mass. When severe and rapid weight loss is achieved by starvation diet, the center does not recognize this as normal and, therefore, reprograms itself to cause weight gain rapidly once the person goes off the starvation diet. So the only effective way of losing weight is slow, self-controlled, and gradual weight loss which can be achieved by modifying our behavior and changing our attitude about eating especially by eliminating excess food. Ramadan is a month of self-regulation and self-training in terms of food intake thereby causing hopefully, a permanent change in lipostat reading. 3. With the prescribed fast, Muslims are not subjected to a diet of selective food only (i.e. protein only, fruits only etc.). An early breakfast, before dawn is taken and then at sunset the fast is broken with something sweet i.e. dates, fruits, juices to offset any hypoglycemia followed by a regular dinner later on. 4. Additional prayers are prescribed after dinner which help metabolize the food. Using a calorie counter, I counted the amount of calories burnt during the special night prayer of Ramadan (Taraweeh). It amounted to 200 calories. This form of prayer as well as the five daily prescribed prayers use all the muscles and joints and can be considered a mild form of exercise in terms of calorie output. 5. Ramadan fasting is actually an exercise in self discipline. For those who are chain smokers or who nibble food constantly, or drink coffee every hour, it is a good way to break the habit. 6. The psychological effect of Ramadan fasting are also well observed by the description of people who fast. They describe a feeling of inner peace and tranquility. The Prophet (peace be upon him) advised those fasting, “If one slanders you or aggresses against you, tell him ‘I am fasting.”' Thus personal hostility during the month is minimal. The crime rate in Muslim countries falls during this month. It is my experience that within the first few days of Ramadan, I begin to feel better even before losing a single pound. I work more and pray more. My physical stamina and mental alertness improve. As I have my own lab in the office, I usually check my chemistry, that is, blood glucose, cholesterol, and triglyceride before the commencement of Ramadan and at its end. I note marked improvement at the end. As I am not overweight, Alhamdulillah, weight loss is minimal. The few pounds I lose, I regain soon after. Fasting in Ramadan will be a great blessing for the overweight whether with or without mild diabetes (Type 11). It benefits those also who are given to smoking or nibbling. They can rid themselves of these addictions in this month. – SG Soliman, N. “Effects Of Fasting During Ramadan,” Journal of the Islamic Medical Association, November 1987. __
