Catholics between the ages of 18 and 59 are obliged to fast on Ash Wednesday and Good Friday. In addition, all Catholics 14 years old and older must abstain from meat on Ash Wednesday, Good Friday and all the Fridays of Lent.

Fasting means partaking of only one full meal. Some food (not equaling another full meal) is permitted at breakfast and around midday or in the evening—depending on when a person chooses to eat the main or full meal.

Abstinence forbids the use of meat, but not of eggs, milk products or condiments made of animal fat.
