Functional Medicine Meets Performance With Westley Spiro, MD

“It is not about doing more.
It is about doing what actually moves the needle.”

In this episode of The Axis Method, I sat down with Westley Spiro MD—functional medicine physician and founder of Catalyst Precision.

What made this conversation different is that Dr. Spiro doesn’t just talk about health—he lives it. His training, nutrition, supplementation, and clinical practice all align around one principle:

Optimization through intelligent consistency.

This conversation bridges two worlds:

• Performance training

• Functional medicine

And shows how they should never be separated.

Dr. Spiro’s current structure is simple—and that’s the point.

• Push / Pull split (4 days/week)

• Sprint-based conditioning (2–3 days/week)

• Focus on explosive movement over maximal loading

Key takeaways:

• Sprinting may be one of the most underutilized tools for mitochondrial health and hormone response

• You don’t need high volume—you need high intent

• Joint longevity > ego lifting

We aligned heavily here:

The Minimum Effective Dose is not about doing less—it’s about doing what matters most.

Some of his current staples:

• Romanian Deadlifts

• Bulgarian Split Squats

• Dumbbell Pressing

• Weighted Pull-Ups & Dips

• Rear Delt / Scapular Work

Why it matters:

• Less axial load → more longevity

• Unilateral work → better structural balance

• Dumbbells → joint-friendly strength

This mirrors what I’ve seen for years:

Most lifters don’t need more load—they need better positioning and control.

Key concept:

• Multivitamins = convenience, not optimization

• Blood work should guide supplementation

This aligns directly with how I structure DRESS protocols for clients.

This was one of the strongest sections of the episode.

Key principles:

• Deep sleep = growth hormone + testosterone release

• Circadian rhythm drives everything

• Consistency > total hours

His non-negotiables:

• Same sleep/wake time

• No screens before bed

• Morning sunlight immediately upon waking

I’ll echo this:

If your sleep is off, everything else is just noise.

We broke down the current landscape:

• BPC-157 / TB-500 → recovery (limited human data)

• Growth hormone peptides → performance + body composition

• GLP-1s → metabolic control, not just fat loss

Big takeaway:

The peptide conversation isn’t about shortcuts—it’s about regulation catching up to reality.

The future likely looks like:

• Physician-guided use

• Better quality control

• More personalized dosing

This was one of the most valuable parts for listeners.

Dr. Spiro emphasized:

• Testosterone is a health marker, not just a performance tool

• Optimization ≠ abuse

• Many men are suboptimal, not deficient

Key option discussed:

• Stimulates natural testosterone production

• Preserves fertility

• Avoids shutdown seen with TRT

What stood out most:

When testosterone improves, energy, mood, and consistency improve first—physique follows.

We built out a real-world avatar:

• Male, mid-40s

• High stress

• Trains inconsistently

• Slight fat gain

• Energy fluctuations

First steps in care:

1. Comprehensive blood work

2. Lifestyle audit (sleep, diet, stress)

3. Training frequency correction

4. Hormone evaluation

Notably:

Most people don’t need more complexity—they need better execution of fundamentals.

From Dr. Spiro’s perspective:

• Scale weight

• Complex protocols

• Over-tracking everything

• Strength training

• Meal timing

• Sleep consistency

• Blood glucose control (A1C)

• Most overrated supplement: Calcium

• Most underrated habit: Meal timing

• One marker to track: A1C

• Longevity driver: Strength training

• Recovery tool: Sauna > cold plunge

• Morning essential: Sunlight immediately

Dr. Spiro operates the same way I coach.

• Start simple

• Measure what matters

• Build consistency

• Layer in precision over time
