Lifting Weights During Lent: How to Get Enough Protein While Fasting

You train hard. You also fast. These two commitments are not in conflict, but they do require you to think about what you eat during Great Lent with more precision than someone who spends their evenings on the couch. This guide is for lifters, athletes, and anyone doing serious physical work who wants to keep the fast without losing muscle or feeling like death by week three.

THE PROBLEM, STATED PLAINLY

For seven weeks (plus the preceding weeks of Cheesefare and the pre-Lenten preparation), you are eating no meat, no dairy, and no eggs. On most days, no fish either. These happen to be the foods that most strength athletes rely on for protein. A chicken breast has 31g of protein. A cup of Greek yogurt has 20g. Three eggs have 18g. All of these are off the table.

The standard recommendation for lifters is 0.7-1g of protein per pound of bodyweight per day. If you weigh 180 pounds, that means 126-180g of protein daily. Hitting that range on a fasting diet is absolutely possible, but it will not happen by accident. You need a plan.

FASTING PROTEIN SOURCES, RANKED BY DENSITY

These are the foods that will do the heavy lifting for you. Learn them, stock them, and rotate through them.

Seitan (vital wheat gluten): 25g protein per 100g serving. This is the undisputed king of fasting protein. It has a dense, chewy texture that works in stir-fries, curries, and stews. If you are not gluten-intolerant, seitan should be a staple of your Lenten diet. You can buy it prepared or make it from vital wheat gluten flour in under an hour.

Tempeh: 31g protein per cup. Fermented soybeans with a firm, nutty texture. Excellent sliced and pan-fried with soy sauce on oil days, or simmered in a curry on strict days. The fermentation makes it easier to digest than plain soy.

Tofu (extra-firm): 20g protein per block (roughly 400g). Not the highest density, but incredibly versatile. Press out the water, cube it, and bake or fry it. Absorbs any flavor you put on it.

Lentils: 18g protein per cup cooked. The backbone of fasting cuisine worldwide. Also delivers 16g of fiber and significant iron. Cook a big pot on Sunday and eat it all week.

Chickpeas: 15g protein per cup cooked. Outstanding in stews, curries, roasted as snacks, or blended into hummus. Canned chickpeas are perfectly fine — rinse and use.

Black beans: 15g protein per cup cooked. A staple for a reason. Excellent in rice bowls, soups, or mashed into patties.

Shellfish (shrimp, mussels, squid, clams, octopus, crab): Permitted on ALL fasting days throughout the entire year. This is not a relaxation — shellfish has never been classified as fish in Orthodox fasting discipline. Shrimp delivers roughly 24g of protein per 100g serving with almost zero fat. A plate of shrimp with rice and vegetables is a perfect post-training fasting meal. Do not overlook this. Shellfish is your secret weapon.

Nuts and seeds: Almonds (21g per cup), peanuts (38g per cup), pumpkin seeds (12g per cup). Calorie-dense, so do not rely on them as your primary source, but excellent for adding 10-15g to a meal.

PEA PROTEIN: THE PRACTICAL SOLUTION

Here is the straightforward reality: if you are genuinely struggling to hit your protein targets through whole foods alone, a simple pea protein powder mixed with water is fully fasting-compliant. It contains no animal products whatsoever. A single scoop delivers 20-25g of protein.

There is no shame in this. It is a practical solution, not a relaxation of the fast. You are not sneaking in dairy whey or casein — pea protein is a legume product, as fasting-appropriate as a bowl of lentil soup. Some monastics and clergy specifically recommend it for those doing physical labor or athletic training during fasting periods. A scoop in water after training and a scoop mixed into oatmeal in the morning can add 40-50g of protein to your daily intake with zero compromise to the fast.

SAMPLE HIGH-PROTEIN FASTING DAY (~140g protein)

This is a sample day for an oil-permitted day (Saturday or Sunday during Lent). Adjust portions to your size and caloric needs.

Breakfast:
- Oatmeal made with water (5g protein)
- 1 scoop pea protein stirred in (22g protein)
- 2 tablespoons peanut butter (7g protein)
- Banana
Total: ~34g protein, ~500 calories

Lunch:
- Large bowl of lentil soup with 1.5 cups lentils (27g protein)
- Bread with olive oil
- Side of hummus with raw vegetables (6g protein)
Total: ~33g protein, ~550 calories

Post-training:
- 1 scoop pea protein in water (22g protein)
- Handful of almonds (6g protein)
Total: ~28g protein, ~250 calories

Dinner:
- 200g shrimp stir-fried with vegetables and soy sauce (48g protein)
- Jasmine rice
Total: ~48g protein, ~600 calories

Daily total: ~143g protein, ~1,900 calories

On strict days (no oil), replace the stir-fry with boiled or steamed shrimp and use lemon juice instead of frying. Replace the peanut butter with a tablespoon of tahini stirred into the oatmeal. You will lose some calories but the protein stays high.

TRAINING AND TIMING ADVICE

Do not skip meals. The single biggest mistake fasting lifters make is eating too little because they assume fasting means hunger. Fasting means abstinence from specific foods, not starvation. Eat enough to fuel your training.

Keep your carbohydrates up. Rice, potatoes, oats, bread, pasta — these are all fasting-compliant and your body needs them for energy, especially around training. A lifter who eats only protein and vegetables during Lent will feel terrible by week two.

Keep your training volume the same. You may want to reduce intensity (weight on the bar) by 5-10% during the first week as your body adjusts to the dietary shift. By week two, most lifters report feeling normal again. Some report feeling better — the increased fiber and reduced processed food intake has that effect.

Train at whatever time works for your schedule, but try to eat within an hour after training. A pea protein shake immediately post-training followed by a full meal within 90 minutes is ideal.

THE SPIRITUAL ANGLE

Here is the truth that nobody on a fitness forum will tell you: fasting IS supposed to be somewhat difficult. If you engineer your diet so perfectly that you notice no difference between Lent and the rest of the year, you have arguably missed something.

The slight physical challenge of training while fasting — the moments when you wish you could just eat a steak, the extra effort of meal prep, the discipline of planning your food — this is part of the asceticism. It is a small offering. Do not romanticize it, but do not dismiss it either.

The temptation for lifters is to treat their training as a reason to relax the fast. "I need the protein" becomes "I need eggs at breakfast" becomes "I basically cannot fast because I lift." This is nonsense. Generations of Orthodox laborers — farmers, soldiers, builders — kept the fast while doing far more physical work than your push-pull-legs split demands. You can do this.

Use your training as a form of discipline that complements the fast. Offer the discomfort. Keep the rule. Eat your lentils and shrimp and seitan. You will be fine.

REMEMBER: SHELLFISH IS ALWAYS PERMITTED

This bears repeating because many people do not know it. Shrimp, mussels, squid, clams, octopus, crab, and all other shellfish are permitted on every single fasting day, including the strictest days of Great Lent. They are an excellent, complete protein source. A bag of frozen shrimp in your freezer is the single best insurance policy against protein deficiency during the fast.
