Catholics, age 14 and over, are to abstain from meat on Good Friday, and all Fridays of Lent.
Individuals between 18 and 59 are also obliged to fast - eat only one full meal - on Good Friday. Eating two smaller meals is permitted if necessary to maintain strength, but eating between meals is not.
These obligations do not apply to those whose health or ability to work would be seriously affected.
Catholics are also encouraged to do penancy in other ways, such as prayer, acts of self denial, almsgiving, and through works of kindness and compassion.
