Your "high-protein breakfast" might be why you're hungrier by lunch.
Not because protein is bad, it's the most satiating macronutrient we have.
But the way most people do it creates a problem nobody talks about.

The fix. Precision Nutrition's hand-portion system:
1 palm protein (~20-30g)
1 fist vegetables/fruit
1 cupped hand smart carbs
1 thumb healthy fat
No app. No food scale. No calculator.
Works for every body size. Travels everywhere.

The good news:
"Moderate" diet quality was ENOUGH.
You don't need to be a nutritional saint. You need to be consistently adequate.
1 fist of vegetables at 2 meals. Fish 2x/week. Minimal ultra-processed food.
For 30 years.

The question that haunts me now:
"If I ate exactly like this for the next 30 years, what would my brain look like?"
Don't wait for your wake-up call.
Start now. Start small. Keep going.

Two-time cancer survivor. Best shape of my life at 40 .
How? I stopped listening to wellness influencers and became my own lab rat.
The truth: 90% of health advice is marketing, not science.

Spent 12 years fighting cancer.
Grew a VC portfolio from €36M to €100M .
Left finance because it felt empty.
Built a health tech startup.
Just realized I was running FROM my calling, not TO it.
