Your First Great Lent: A Practical Guide for New Converts

Published April 10, 2026

You are about to fast for the first time, or at least the first time seriously. Maybe you were received into the Church last year, or you have been attending for a while and have decided that this is the Lent where you actually keep the fast. You are probably a little nervous. That is normal.

This guide will give you everything you need to get through your first Great Lent with your body fed, your spirit growing, and your sanity intact.

FIRST: TALK TO YOUR PRIEST

This is not optional advice. Before you do anything, talk to your priest about what level of fasting is appropriate for you. The full monastic fasting rule — no meat, no dairy, no eggs, no fish, no oil, no wine on weekdays, with various gradations on weekends and feast days — is exactly that: a monastic rule. It was written for monks. You are probably not a monk.

Most priests will give new fasters a modified rule. Maybe you start by eliminating meat and dairy but keep fish. Maybe you fast fully on Wednesdays and Fridays and eat normally otherwise. Maybe you go the full distance but keep oil and wine throughout. The specific rule matters far less than the fact that you are fasting with your priest's blessing and guidance. Do not let the internet tell you what your priest should tell you.

THE BASIC STRUCTURE

For reference, here is what the standard Great Lent fasting rule looks like:

- No meat for the entire duration (beginning with Meatfare Sunday, a week before Lent starts)
- No dairy, eggs, or fish for the duration of Lent itself (Clean Monday through Holy Saturday)
- Oil and wine are permitted on Saturdays and Sundays
- Fish is permitted on the Annunciation (March 25) and Palm Sunday
- Shellfish (shrimp, mussels, squid, clams, etc.) is permitted on ALL days — it is never restricted
- The first week and Holy Week are traditionally the strictest

Again: your priest may adjust this for you, and that is perfectly fine. The fast is medicine for the soul, and good medicine is prescribed in the right dose for the individual patient.

PRACTICAL PREPARATION: BEFORE LENT STARTS

The most important thing you can do is prepare before Clean Monday arrives. Here is how:

Learn 5-6 fasting meals you actually enjoy. Do not wait until the first day of Lent to figure out what you can eat. In the weeks before Lent, cook fasting meals and find the ones you genuinely like. A bean chili, a Thai curry with tofu, a lentil soup, a shrimp stir-fry, a pasta with olive oil and garlic and vegetables — find your staples and practice them.

Stock your pantry. Get your dried beans, lentils, rice, canned goods, spices, and condiments in order before Lent begins. (See our Stocking Your Fasting Pantry guide for the complete list.) If your kitchen is ready, you will never be stuck staring at an empty fridge wondering what to eat.

Meal prep on Sundays. This is the single most effective habit for Lenten eating. Cook a big pot of soup or stew, prepare a batch of grains, roast a tray of vegetables. Portion them out for the week. When you come home tired on a Tuesday evening, the difference between a prepped fridge and an empty one is the difference between keeping the fast and ordering a pizza.

Tell the people you live with. If you have a spouse, roommates, or family members who do not fast, let them know what you are doing and why. You do not need their permission, but you do need them to not wave a cheeseburger under your nose during the first week.

COMMON MISTAKES NEW FASTERS MAKE

Eating too little. Fasting means abstaining from certain foods. It does not mean starving yourself. You should feel hungry sometimes — that is part of the discipline — but you should not feel weak, dizzy, or unable to function. If you are losing weight rapidly, feeling exhausted by midday, or unable to concentrate, you are not eating enough. Eat more beans. Eat more rice. Eat more bread. These are all fasting foods and your body needs fuel.

Eating only carbohydrates. This is the most common nutritional mistake. You cut out meat and dairy, and suddenly every meal is pasta, bread, and potatoes. By week two you feel sluggish, bloated, and miserable. Prioritize protein at every meal — lentils, beans, chickpeas, tofu, seitan, shellfish, nuts. Your body needs protein to function, fasting or not. (See our Lifting Weights During Lent guide for detailed protein source rankings, even if you do not lift.)

Going too strict too fast. You are not on Mount Athos. If your priest has blessed you to keep oil throughout Lent, keep oil throughout Lent. Do not decide midway through that you should go stricter because you read a blog post about xerophagy. Increasing strictness beyond what your priest has blessed is not piety — it is self-will, and it often ends in burnout and breaking the fast entirely.

Feeling guilty about imperfect fasting. You will probably slip. Maybe you eat cheese by accident because you forgot to check a label. Maybe you give in and eat fish on a day when it is not permitted. Maybe you have a bad week and eat meat. When this happens, go to confession, talk to your priest, and continue the fast. Do not spiral into guilt. Do not give up because you failed once. The fast is a practice, not a performance.

Consulting the internet instead of your priest. Orthodox fasting forums and social media are full of scrupulous people arguing about whether a particular brand of bread contains a trace amount of whey powder. This will make you anxious and miserable. Your priest is your guide. Not Reddit. Not Facebook groups. Not that one guy on Twitter who posts the typikon every day.

THE SPIRITUAL REALITY

Here is what matters: the goal of fasting is not dietary purity. It is spiritual growth. Fasting is a tool — one of several that the Church gives us during Lent, alongside increased prayer, almsgiving, and attendance at services. The food rules serve the soul. They do not replace it.

A humble person who eats oil on a non-oil day because they did not know the rule, or because they are struggling, or because their priest told them to, is in a far better spiritual position than a prideful person who keeps perfect xerophagy and looks down on everyone who does not. If you remember nothing else from this guide, remember this.

Fasting should make you more compassionate, not less. More aware of your dependence on God, not more confident in your own willpower. If your fasting is making you irritable, judgmental, and self-righteous, something has gone wrong — and the problem is not your diet.

YOUR SECRET WEAPON: SHELLFISH

Many new Orthodox Christians do not realize this: shellfish is permitted on every single fasting day, including the strictest days of Great Lent. Shrimp, mussels, squid, clams, crab, octopus, scallops — all of these are always allowed.

This is an enormous practical advantage. A bag of frozen shrimp in your freezer means you are never more than 15 minutes from a high-protein fasting meal. Shrimp stir-fried with vegetables and soy sauce over rice. Mussels steamed in white wine and garlic. Squid simmered in tomato sauce with potatoes. These are not compromise meals — they are genuinely delicious food that happens to be fully fasting-compliant at every level of strictness.

If you are struggling with protein, energy, or just the monotony of beans and rice, shellfish is the answer. Stock up on it.
