Background Levels of cortisol, melatonin, ghrelin, and leptin are highly correlated with
circadian rhythmicity. The levels of these hormones are affected by sleep, feeding, and …

We aimed to assess the effect of Islamic intermittent fasting, during and outside of Ramadan,
on plasma levels of leptin and ghrelin while controlling for several potential confounding …

Background Muslims go through strict Ramadan fasting from dawn till sunset for one month
yearly. These practices are associated with disturbed feeding and sleep patterns. We …

We studied the effects of Ramadan intermittent fasting (RIF) on gut hormones (leptin,
glucagon-like peptide-1 (GLP-1), peptide YY (PYY), cholecystokinin (CCK), and ghrelin) in …

Background: Fasting during the month of Ramadan for Muslims is a unique metabolic model
that includes abstinence from food and fluid intake during the period from dawn to sunset as …

& Peret et al.[1] showed a phase shift in liver glycogen circadian rhythm induced by timed
food intake in the rat. Furthermore, our previous results in rats showed a significant decrease …

Aim Studies on the effect of Ramadan diurnal intermittent fasting (RDIF) on glucometabolic
markers have yielded conflicting results. We conducted a meta-analysis to estimate the …

Muslims must refrain from eating, drinking, smoking, and sexual relations from sunrise to
sunset during the month of Ramadan. Serum concentrations of melatonin, steroid hormones …

Purpose Studies on the effect of Ramadan diurnal intermittent fasting (RDIF) on body weight
have yielded conflicting results. Therefore, we conducted a systematic review and meta …

We hypothesize that factors other than a sudden shift in eating habits contribute to delay of
circadian rhythms during Ramadan. We assessed circadian changes during a baseline …
