Ash Wednesday and Good Friday are obligatory days of fasting and abstinence for Catholics. In addition, Fridays during Lent are obligatory days of abstinence.
The norms on fasting are obligatory from age 18 until age 59. When fasting, a person is permitted to eat one full meal. Two smaller meals may also be taken, but not to equal a full meal.
The norms concerning abstinence from meat are binding upon members of the Catholic Church from age 14 onwards.
NOTE: When health or ability to work would be seriously affected, the law does not oblige. When in doubt concerning fast and abstinence, the parish priest should be consulted.
