BackgroundThe aim of this study is to evaluate the effect of Ramadan intermittent fasting on metabolic markers, dietary intake, anthropometric measurements, and abdominal visceral fat thickness (VFT) in pregnancy.MethodsSeventy-eight healthy pregnant subjects who had fasted for at least 15 days during the month of Ramadan in 2012 and 2013 and 78 controls were included in this study. Metabolic markers, dietary intake, anthropometric measurements, and ultrasonographic VFT were calculated for each subject before and after Ramadan fasting.ResultsWhen before and after Ramadan values in the fasting group were compared, we found that daily protein intake was increased (p <0.001), but fat and carbohydrate intake remained unchanged. A significant reduction was observed in liquid consumption while the frequency of asymptomatic bacteriuria was increased. High-density lipoprotein significantly increased, and glycated hemoglobin, insulin, and homeostasis model index significantly decreased (p =0.005, p =0.01, p <0.001, and p =0.03, respectively). A significant increase in ferritin was found (p =0.02). No change was observed in subcutaneous fat thickness, while VFT significantly decreased (p =0.08, p =0.005). However, in the control group, only ferritin level increased.ConclusionA combined change in the number and timing of meals and the portioning of the entire daily intake into only two meals per day may have beneficial metabolic effects and reduction in VFT during pregnancy.
