Ash Wednesday and Good Friday are days of fast and abstinence from meat. All other Fridays in Lent Catholics are also required to abstain from meat.
FASTING is to be observed by all, 18 years of and older, who have not yet celebrated their 59th birthday. On a fast day, one full meal is allowed. Two other meals, sufficient to maintain strength. may be taken, according to each one’s needs, but together they should not equal another full meal. Eating between meals is not permitted, but liquids, including milk and juices, are allowed.
ABSTINENCE is observed by all 14 years of age and older. On days of abstinence, no meat is allowed. Note that 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. (CCC 1251-1252)
Fasting, almsgiving, and prayer are the three traditional disciplines of Lent. The faithful and catechumens should undertake these practices seriously in a spirit of penance and of preparation for baptism or renewal of Baptism at Easter.
