Yes, in the Roman Catholic Church , Ash Wednesday is a day of both fasting and abstinence for most adult Catholics.

Who is supposed to fast?

  • Fasting (one full meal plus two smaller meals that together do not equal a full meal) is obligatory for Catholics between ages 18 and 59 , unless they have a medical or other serious reason that excuses them.
  • Abstinence from meat is required for all Catholics age 14 and older on Ash Wednesday and Good Friday.

What “fasting” means in practice

  • You may eat one regular‑size meal in the day.
  • You may have two smaller meals or snacks , but those two together should not equal a full meal.
  • You are still allowed to drink water and other beverages ; the fast is about food quantity, not hydration.

Who is excused or can adapt?

  • People with health issues, pregnancy, breastfeeding, very demanding work, or other serious needs are not expected to fast in a way that harms them.
  • Many bishops’ conferences allow substituting other penitential works (like extra prayer, charity, or giving up luxuries) in place of strict fasting for those who cannot do it.
