The Doctor Who Eats Like a Scientist

Randy D’Amico doesn’t follow food trends or fad diets.
He eats with intention. Simple. Measured. Backed by data.

When your job involves performing brain surgery for hours at a time, you don’t gamble with energy. You don’t eat for excitement. You eat for stability.

His philosophy is built around one core principle:

Keep your energy steady.
No spikes. No crashes. No drama.

And the way he does it is refreshingly simple.

This same mindset shows up in how he thinks about pressure and decision-making, something we explored in How to Stay Calm Under Pressure: Lessons from a Neurosurgeon.

Morning Foundation: Start With Stability

Dr. D’Amico starts his day with:

  • Avocado toast on seedy, low-glycemic bread

  • Hot sauce for flavor and a mild metabolic kick

It’s not flashy. It’s functional.

Healthy fats keep energy steady.
Fiber slows digestion.
Low-glycemic carbs prevent a crash an hour later.

The goal isn’t fullness. It’s clarity.

When your brain has work to do, fog is the enemy.

Research from Harvard Medical School supports this approach, showing that low-glycemic breakfasts help maintain focus and reduce energy crashes throughout the day.

Mid-Morning Fuel: Protein Without the Spike

His mid-morning meal is just as intentional:

  • Two Greek yogurts

  • Chia seeds

  • Hemp seeds

High protein. Low sugar. Minimal processed carbs.

This isn’t about restriction. It’s about control.

Enough fuel to sustain focus.
Not enough to overwhelm the system.

This type of steady fueling mirrors what we talk about in How To Build Consistency Without Burning Yourself Out, where sustainability beats intensity every time.

Afternoon Strategy: Energy Without Anxiety

Instead of reaching for another coffee, he shifts gears:

  • Peanut butter on quality toast

  • Green tea instead of caffeine overload

Green tea delivers a calmer form of stimulation.
Peanut butter provides fat and protein that digest slowly.

The result is steady energy through long afternoons without jitters or burnout.

According to The Cleveland Clinic, minimizing blood sugar swings and excessive caffeine helps regulate mood, focus, and long-term cognitive performance.

When your nervous system stays regulated, your decisions stay cleaner.

Evening Approach: Recovery Over Perfection

Dinner isn’t about discipline theater. It’s about recovery.

  • Low-glycemic pasta when possible

  • Lots of vegetables, especially leafy greens

  • Whole foods over processed shortcuts

He eats clean, but realistically.

Consistency beats obsession.
Sustainability beats rules.

This perspective aligns with The Mindset Shift That Can Change Your 20s with Kane Kallaway, where long-term habits matter more than short-term discipline.

The Data Behind the Diet

At one point, Dr. D’Amico tracked his food response obsessively.

“I became obsessed with a glucometer for a period of time. I was just watching my glucose trends and trying to flatten the curve.”

That’s the key phrase: flatten the curve.

He wasn’t chasing weight loss.
He was chasing predictable energy.

What he watches instead of calories:

  • Blood glucose stability

  • Heart rate variability

  • Recovery quality

  • Sleep consistency

This is science without hype.
Biofeedback instead of biohacking.

Supplements That Actually Matter

Despite his medical background, his supplement list is short.

Creatine

“There’s enough scientific backing on it. There’s the brain health component and the muscle recovery component.”

Creatine supports both physical performance and cognitive function. It’s one of the few supplements with real evidence behind it.

Magnesium

Used to support sleep and recovery.

After melatonin caused grogginess and strange dreams, magnesium became the better option.

Everything else?

“Supplements are tricky because they’re not FDA regulated. You have to be really careful.”

Simple rule:
If it’s not proven, skip it.

The Guyset Takeaway

Dr. D’Amico’s approach to food is what most guys actually need.

Not more rules.
Not more trends.
Not more extremes.

Just:

  • Eat to stabilize energy

  • Use data when possible

  • Keep it simple enough to repeat

  • Stop turning food into a personality

Whether you’re in an operating room or a regular workday, the principle holds.

Stable inputs create stable outputs.
