Protein fasting?

You’re asking exactly the right questions—this is where things “click” and your routine becomes intentional instead of just clean eating.
1) About the
OWYN protein drink (“packaged”)
Your instinct is understandable, but I’d reframe it:
Yes, it’s processed
But it’s also:
plant-based
convenient
~20g protein in seconds
Think of it as a tool, not a staple
👉 You don’t need it, but it solves a real problem:
It’s hard to hit 80–100g protein on vegetarian + fasting without some efficiency
Better alternatives (less “packaged” feel):
Greek yogurt (you already do this ✔️)
Cottage cheese
Eggs (if you include them)
Lentils / beans
Tofu / tempeh
But realistically:
A protein shake is often the difference between 40g and 90g in your day
2) “I thought peas were high protein?”
They are—but this is where perception vs reality diverges.
1 cup peas ≈ 8g protein
Compare:
Greek yogurt → 15–20g
Lentils (1 cup cooked) → ~18g
Tofu (1 block) → ~30–40g
👉 So peas are:
nutrient-dense
but not a primary protein anchor
Think of them as a supporting player, not the main source.
3) Timing around tennis (this is key for you)
You’re active and competitive—timing will matter for:
reaction speed
endurance
recovery
Before tennis (30–90 minutes prior)
You want:
light
digestible
not heavy fat
Good options:
Greek yogurt
Banana + small yogurt
Half protein shake
👉 Goal: 10–20g protein + a little carbs
This helps:
quick energy
prevents sluggishness
After tennis (this is the big one)
This is when your body is most receptive.
👉 Within ~1–2 hours:
Main meal with:
30–50g protein
vegetables
some carbs
This supports:
muscle repair
recovery
maintaining strength for your next session
4) How this fits your intermittent fasting
You don’t need to break your fasting philosophy—you just align your eating window with activity
Example (tennis day)
Morning (fasted)
Meditation (you’ve noticed the benefit)
Light activity
Pre-tennis (break fast)
Greek yogurt (+ maybe fruit)
→ ~20g protein
Post-tennis meal
Lentils or tofu + vegetables + avocado
→ ~40g protein
Optional later
Cottage cheese or shake
→ +20g protein
5) Your current pattern (honest assessment)
What you did:
peas + Greek yogurt + avocado
That’s:
clean ✔️
healthy ✔️
but underpowered for your activity level
6) Simple upgrade (no complexity)
Keep everything you’re doing, just add:
One real protein anchor per day
lentils, tofu, eggs, or shake
That alone shifts you from:
~30g → 70–100g
Final insight (this is the “non-obvious” part)
Your instinct is:
“Eat clean, eat less, fast more”
But for your lifestyle (tennis + swimming + gym):
The winning formula is: eat clean + fast + deliberately add protein
That’s what lets you:
drop from 42” → 40” waist
without losing sharpness or strength on the court
If you want, I can design a fully vegetarian, mostly whole-food day that hits ~100g protein without relying on shakes much at all.
