As outlined on the U.S. Conference of Catholic Bishops' website on
Lenten fasting and abstinence, fasting is obligatory for all who have completed their 18th year and have not yet reached their 60th year. Fasting allows a person to eat one full meal. Two smaller meals may be taken, not to equal one full meal. Abstinence (from meat) is obligatory for all who have reached their 14th year. Fridays in Lent are obligatory days of complete abstinence (from meat) for all who have completed their 14th year. Abstinence means not eating meat. All persons 14 years and older are bound by the law of abstinence. Ash Wednesday and Good Friday are Days of both Fast and Abstinence. If possible, the fast on Good Friday is continued until the Easter Vigil (on Holy Saturday night) as the . . 'paschal fast' to honor the suffering and death of the Lord Jesus, and to prepare ourselves to share more fully and to celebrate more readily his Resurrection.
Through our works of prayer, fasting, and abstinence, let us heed the prophet Joel's exhortation to return to God with our whole heart (2:12). Lent is a penitential season and as such religious practice such as daily Mass, reception of the Sacrament of Penance, the devotion of the Stations of the Cross, works of charity and justice, and acts of self-denial are highly encouraged.
Fasting allows one full meal, but a light breakfast and lunch are not forbidden. All adults, 18 up to the beginning of their sixtieth (60) year, are bound by the law of fasting. Pastors and parents are to see to it that children, while not bound to the law of fast and abstinence, are educated and introduced to an authentic sense of penance.
It is recommended that on Fridays, when abstinence is not required by law, acts of penance, especially works of charity and exercises of piety are suggested. Abstinence from meat is especially recommended but under no obligation by law.
