“…Ramadan, (2002), explored the effect of Ramadan fast on body composition, plasma constituents, hematology, and cardio respiratory responses to constant sub-maximal exercise. Also, Bouhlel et al, (2006) who investigated the effect of sub-maximal exercise in nine trained rugby player in three occasions and two statuses: before, first week, last week of Ramadan fasting, and at rest and acute exercise.…”

During the holy month of Ramadan the quality of food and eating patterns changed and drinking will be stopped for at least 10 to 16 hours on the basis lunar calendar. The effects of exercise and fasting solely or combined on metabolic and hematologic responses well established. The purpose of the present study was to study the effects of Ramadan fasting with or without weight-lifting training on vascular volumes and selected hematological indices in young male weight-lifters. Blood samples were taken at 24h before and 24h after the last day of holy Ramadan fasting period and weight-lifting training for determination of the selected red and white blood cells compositions. The Vascular volumes (Blood, Red cells, and plasma volumes) were determined and calculated by using both hemoglobin and hematocrit estimations before and after Ramadan fasting with or without weight-lifting training. The results indicate that red cell volume and MCHC were significantly decreased and increased in fasting group (P<0.05) respectively. The percentages of hematocrit were significantly low in both training and fasting groups. A higher and significant platelet count was found in training group. The present data indicate that weight-lifting training during the holy Ramadan in compare to fasting had no impact on red and white cells composition exception on platelet count and Hematocrit. A decrease in Hematocrit might be due to the incomplete dehydration period which amplified by stop drinking and nutritional habits during the holy Ramadan.

“…It suggested that the high water turnover, likely presented in the more active group, allows more precise regulation of the body water than the lower water turnover which is presented in the sedentary group (7). During Ramadan, signs of dehydration have been identified by increased measures of hematocrit, hemoglobin and plasma osmolarity (6,7,26). Trablesi et al study indicated a similar hemoconcentration in resting state and a significantly increased hematocrit, hemoglobin and plasma osmolarity during Ramadan.…”

“…This research revealed that following aerobic exercises, the values of hematocrit and hemoglobin are significantly higher in Ramadan than those recorded in periods with normal diet. They suggested a state of dehydration, amplified during Ramadan due to the cumulative effects of uncompensated water loss (6). In contrary, Karli et al observed no changes in body composition and water status, in elite power athletes, during Ramadan (12).…”

“…These changes can lead to a decline in energy intake, loss of body weight and a state of dehydration. The latter is reflected in body weight reduction and changes in biochemical parameters related to body water status (6,7). For instance, Al-Hourani HM surveys showed that body weight and BMI decreased noticeably during fasting periods (8).The reduction of body weight has been reported quite repeatedly, but the connection between weight loss and body fat reduction is not often studied (9).…”

The Effects of Ramadan Fasting on Body Composition

Context:Ramadan is the month of fasting in Islam. Fasting is a religious duty for all healthy adult Muslims. During this month, strong persons abstain from different kinds of food and beverage, from sunrise until sunset. They usually eat a larger (300-700 kcal) meal after sunset and a lighter meal (200-500 kcal) before sunrise. Fasting lowers body weight, body fat percentage and body mass index (BMI). It can elevate high-density lipoprotein cholesterol (HDL-c). Al-Hourani HM studies showed that body weight and BMI decreased significantly during fasting. Body weight reduction has been reported quite frequently, whereas, the relationship between weight reduction and loss of body fat has not been studied. The aim of this review is to describe the effects of fasting on several anthropometric parameters on human body, supported by the evidence-based scientific manuscripts. Evidence Acquisition: Conducting any survey in any scientific field has its own limitations. Carrying out a study in holy Ramadan, with its special circumstances, like altering daily nutritional patterns, fasting hours, less number of daily meals and declining physical activities imposes limitations on any research in this field. Results: The basic information regarding changes in dietary intake and body composition are as follows: the majority of Muslims typically consume two meals per day during this month, including one just before dawn and another one after sunset. However, most studies demonstrated that fasting, in people without health problems, causes dramatic changes in body composition. Conclusions: It can be concluded that fasting has various impacts on different individuals. These variations are highly dependent on daily nutritional habits and the season that Ramadan occurs in.Keywords:Fasting; Body weight; Body Mass Index; Islam Implication for health policy/practice/research/medical education: The aim of this review is to describe the effects of fasting on several anthropometric parameters on human body, supported by the evidence-based scientific manuscripts.
