Catholics fast during Lent mainly by limiting how much they eat on certain days and by avoiding meat on Fridays, with special rules for Ash Wednesday and Good Friday.

Core rules (Latin/Roman Catholics)

For most Catholics in the Latin (Roman) Rite, the basic Lenten fasting rules are:

  • Fasting days: Ash Wednesday and Good Friday are the two required fast days.
  • What “fasting” means:
    • One normal full meal.
    • Two smaller meals that together are not as large as the full meal.
    • No snacking between meals (water and medicine are fine).
  • Abstinence from meat:
    • No meat (from land animals and birds) on Ash Wednesday, Good Friday, and all Fridays of Lent.
* Fish and other non‑meat foods are allowed.

Age ranges:

  • Fasting (one full meal + two small): normally required for Catholics aged 18–59 who are in reasonable health.
  • Abstaining from meat: required from age 14 and up.

Those who are ill, pregnant, very elderly, or have health conditions can be excused or adapt the rules with pastoral guidance.

How it looks in daily life

In practice, a typical Catholic might:

  • On Ash Wednesday and Good Friday:
    • Eat a light breakfast (for example, toast or a small bowl of cereal), a modest lunch, and one full meatless dinner, making sure the two smaller meals together are less than the dinner.
  • On other Fridays in Lent:
    • Eat normally but choose no meat all day (fish, eggs, dairy, vegetables, pasta, etc. are fine).

“Normal meal” is measured by what is normally appropriate for that person, not a fixed universal size, so a manual laborer’s “full meal” might be bigger than someone with a desk job.

Spirit and purpose of fasting

Lent is a 40‑day season of prayer, fasting, and almsgiving leading up to Easter, modeled in part on Christ’s 40 days fasting in the desert. Fasting is meant to:

  • Help Catholics grow in self‑discipline and detach from comforts.
  • Unite them with Christ’s suffering and with the poor.
  • Free up time and resources for prayer and charity.

Many Catholics also “give something up” (like sweets, social media, or unnecessary spending) or take on extra prayer or acts of service as an additional, voluntary Lenten fast.

Variations and Eastern Catholics

The exact rules can vary slightly by country’s bishops’ conference, so local diocesan guidelines are the reference point. Eastern Catholic Churches often have stricter traditional fasts, such as:

  • Abstaining from meat on Wednesdays and Fridays of Lent.
  • Fasting and abstaining from meat, eggs, and dairy on key days like Clean Monday and Good Friday.

These practices keep the same core goal: turning away from sin and toward God through prayer , fasting, and charity.
