Fasting, Explained

The words the Church uses for the fast, and what fasting is for. For the seasons themselves, Great Lent and the rest, see the fasts.

Orthodox fasting keeps from certain foods by degrees, which the calendar marks day by day. The strict fast sets aside meat, fish, dairy, and eggs, and wine and oil as well; lighter days allow wine and oil, or fish too, and the week before Lent sets aside only meat. The measure for you is set with your priest.

These pages explain each level, from the strict fast to the fast-free days, and what fasting is for. For when the fasts fall, see the fasting calendar. For what is eaten, see what to eat on a fast day. For a voluntary fast from apps and websites, see Watchfulness.
