Ash Wednesday is a day of fasting for adults age 18-59. Ash Wednesday and all Fridays are days of abstinence from meat for those over the age of 14. When fasting, a person is permitted to eat one full meal, as well as two smaller meals that together are not equal to a full meal. Those that are excused from fast and abstinence include the physically or mentally ill, including individuals suffering from chronic illnesses such as diabetes. Also excluded are pregnant or nursing women.
