Ash Wednesday, like Good Friday, is a day of Fasting and Abstinence from meat. The law of abstinence from meat is binding on those who are 14 and older. The law of fasting is binding on those who are 18 to 59 years of age. The requirement for fasting is that you can have one full meal and two other small meals in such a way that the two meals don’t add up to a full meal (and of course, no meat). If required you may drink beverages between meals but not something that is very filling (such as milkshakes).
