What to Eat During Fasting Without Losing Muscle (Complete Guide)

Nutrisium Insight (Cyprus):

Worried you’ll lose muscle during Orthodox fasting? Here’s the truth most people don’t talk about.

Every year, during the Orthodox Easter fasting period, people clean up their diet, remove animal products, and try to stay consistent.

But something else usually happens too:

👉 Strength drops

👉 Energy dips

👉 Muscle slowly disappears

Not because fasting is bad.

But because protein disappears from the diet and nothing replaces it properly.

The good news?

👉 You can maintain muscle during fasting if you approach it correctly.

Why Muscle Loss Happens During Fasting

Let’s keep this simple.

When fasting starts, you remove:

Meat
Eggs
Dairy

These are your main protein sources.

Most people replace them with:

Bread
Potatoes
Pasta
Vegetables

And while those foods are fine…

👉 They are low in protein

So your body adapts.

When protein intake drops:

Recovery slows
Strength decreases
Muscle breakdown increases

That’s where the problem starts.

How Much Protein Do You Actually Need?

If your goal is to maintain muscle:

👉 Aim for 1.6 – 2.2g of protein per kg of body weight

Example:

70kg → 110–150g protein daily

Yes, even during fasting.

The Best Foods to Eat During Orthodox Fasting

You don’t need complicated recipes.

Just focus on these:

Lentils & Beans

Your main protein base
Cheap, filling, effective

Chickpeas

Easy to add to anything
Great for salads and snacks

Tofu

One of the best meat replacements
High protein, versatile

Quinoa

One of the few complete plant proteins

But here’s the honest part:

👉 It’s hard to hit high protein targets with food alone.

You can do it, but most people won’t consistently.

That’s where smart supplementation helps.

A Simple Fasting Meal Plan (That Actually Works)

No overthinking. Just structure.

Breakfast

Oats + plant milk
1 scoop Oh Good Vegan Protein Chocolate
Peanut butter

Lunch

Lentils or beans
Whole grain bread
Olive oil

Snack

Fruit + nuts

Post-workout / Afternoon

Shake with Oh Good Vegan Protein Vanilla

Dinner

Vegetables

👉 Simple. Repeatable. Effective.

The Best Supplements to Use During Orthodox Fasting

This is where you make fasting easier — and actually sustainable.

1. Vegan Protein (The Foundation)

If there’s one thing that makes the biggest difference, it’s this.

Using something like:

Helps you:

Hit your daily protein target

👉 This is the easiest way to avoid muscle loss.

2. Creatine (Keep Your Strength)

Most people stop using it during fasting which is a mistake.

Creatine Monohydrate:

If Nutrisium offers creatine, this fits perfectly here.

Adding Omega-3 Fatty Acids helps:
