What to Eat During Fasting Without Losing Muscle (Complete Guide)
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
- Rice or quinoa
👉 Simple. Repeatable. Effective.
The Best Supplements to Use During Orthodox Fasting

Using something like:
Helps you:
