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.
