Fasting and Abstinence for Catholics in the U.S. During Lent, Catholics in the United States abstain from meat on Ash Wednesday and on all the Fridays of Lent. They fast on Ash Wednesday and Good Friday. To abstain from meat on Ash Wednesday and all the Fridays of Lent means to not eat meat on those days. It does not intend the omission of eggs or dairy products. The required fast on Ash Wednesday and Good Friday involves eating only one full meal on those days. One or two smaller meals may be taken on those days, but may not total one full meal. The required fast does not allow eating anything between meals. All Catholics who have completed their fourteenth year are bound by the law of abstinence; all adults are bound by the law of fast up to the beginning of their sixtieth year.
