Lenten Rules for Fasting and Abstinence (from the United States Conference of Catholic Bishops)
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 Church from age 14 onwards.
