Muslims are currently observing Ramadan, a holy month when people fast by abstaining from certain activities, including eating and drinking, during the day. Many Christians, Jews and adherents of other religions also practice some form of fasting at certain times of the year. Many Catholics, for example, recently fasted for Lent by abstaining from meat on Fridays, among other things.
In the United States, 21% of adults overall say they fast for certain periods during holy times, according to a Pew Research Center survey from February. Muslim Americans are by far the most likely to say they fast for religious reasons, followed by Jewish Americans, Catholics and Black Protestants.
