The following regulations regarding fasting and abstinence are observed in the United States: Catholics ages 14 and over are to abstain from meat on Ash Wednesday, Good Friday and all Fridays of Lent.
Individuals between 18 and 59 are also obliged to fast – eat one full meal – on Ash Wednesday and Good Friday. Eating two smaller meals is permitted if necessary to maintain strength, but eating between meals should be avoided. These obligations, however, do not apply to those whose health or ability to work would be seriously affected.
Catholics are also encouraged to do penancy in other ways, such as prayer, acts of self denial, almsgiving, and through works of kindness and compassion.
