While standard intermittent fasting allows water intake, Ramadan dry fasting involves total restriction of both food and fluids from dawn to sunset.\n\nResearchers want to see if the combined effects of fluid restriction and natural daily body rhythms during Ramadan trigger a stronger cellular cleanup process (called mitophagy) compared to standard 16:8 water-permitted fasting. The study will look at how these fasting habits change blood markers related to mitochondrial DNA and metabolic health across a 30-day period. This research will help determine if dry fasting offers distinct biological benefits for cellular renewal.",[82,83,84,85,86],"Mitochondrial Degradation","Autophagy","Fasting","Healthy Volunteers","Metabolic Adaptation",[88,89,90,91,92,93,94],"Ramadan fasting","Intermittent dry fasting","Time-restricted feeding","Mitochondrial DNA","Mitophagy","PBMC","PINK1-Parkin","NOT_YET_RECRUITING","2026-06-09",{"date":98,"type":99},"2026-06-11","ACTUAL",{"date":101,"type":78},"2027-01-15",{"date":103,"type":78},"2027-04-30",{"name":5,"class":6},1]
