The Science of Energy Testing for Executives: How to Measure (and Master) Your Metabolic Output

Because your performance isn’t about motivation — it’s about mitochondria.

Why Energy Testing for Executives Beats Willpower (Every Time)

If you're an executive, founder, or high-performing professional, you already know the cost of low energy:

• Mornings feel like molasses

• Brain fog by 2PM

• Workouts don’t give the return they used to

• Caffeine becomes a crutch

Here’s the truth.

You don’t have a time problem. You have an energy mismatch.

And if you want to fix it, you need to stop guessing and start testing.

What Is Energy Testing?

At Miller Health, when we talk about “energy testing for executives,” we’re referring to the science of how your body creates, stores, and spends energy — metabolically, hormonally, and neurologically.

It includes:

• Resting Metabolic Rate (RMR)

• VO2 Max or submaximal fitness testing

• Comprehensive bloods: thyroid, insulin, testosterone, inflammation

• DEXA scan for muscle and fat balance

• Circadian rhythm and redox analysis

• Optional: mitochondrial biomarkers, lactate threshold, HRV trends

Why?

Because without this data, most performance strategies are just trial and error.

And error is expensive when you're trying to lead a company, stay lean, and avoid burnout.

The RMR: Your Metabolic Baseline

Your Resting Metabolic Rate (RMR) tells us how many energy ("calories") your body uses ("burns") at complete rest.

This isn’t about vanity metrics. It’s about whether your system is efficient or stressed.

RMR helps us understand:

• Are you under-fuelling and slowing down?

• Is chronic stress keeping your system in overdrive?

• Are you burning mostly fat or carbs at rest?

Executives with flatlined energy often have suppressed metabolic rates due to circadian mismatch, under-eating, or chronic inflammation.

And once we know that?

We can correct course — with food, training, recovery, light exposure and other 'biohacks' (if we even need them)

VO2 Max (Or Why Your Mitochondria Matter for Performance)

VO2 Max is a marker of aerobic capacity — how well you uses oxygen during activity.

But more importantly, it tells us about mitochondrial function.

Remember the bleep test at school?

Most men over 40 haven’t tested VO2 max since school PE class (if ever)

That’s a missed opportunity.

Low VO2 Max is linked to:

• Higher risk of all-cause mortality

• Faster aging

• Lower stress resilience

• Poor work capacity (mental + physical)

You don’t need to be a marathon runner.

But you do need a cardiovascular system that doesn’t tap out walking up stairs.

Blood Markers: The Energy Saboteurs

Want to know why you’re tired?

Check these:

• Free T3 & Reverse T3 (thyroid metabolism)

• Fasting insulin & HbA1c (sugar burn vs fat burn)

• CRP, homocysteine, IL-6 (inflammatory drag)

• Free testosterone, SHBG, DHEA (fuel for brain + body)

• Cortisol rhythms (chronically wired = constantly tired)

If any of these are off, no amount of coaching, diet plans, or ice baths will fix the fatigue.

You’ve got to treat the source, not the symptom.

Circadian Health: The Invisible Driver of Output

This is where most health providers fall flat.Your energy doesn’t just depend on food and sleep — it depends on light, timing, and something known as redox biology.

“Energy isn’t something you get. It’s something you make — through coherence between the environment and your mitochondria.”— Dr Max Gulhane

If you:

• Wake up in the dark

• Train under artificial lights

• Work in an office cave

• Eat late at night

• "Doom Scrolling" or those 'last emails' before bed...

...you’re disrupting your natural energy rhythm, killing your ATP output, and shortening your lifespan.

We test this. We track it. And then we optimise it.

Energy Is the KPI of the Executive

Think about it:

• More energy = better focus, leadership, communication

• More energy = consistent workouts, sharper thinking, better mood

• More energy = resilience in crisis

This isn’t a luxury.It’s a competitive advantage.

How We Do It at Miller Health

Every client gets:

✅ RMR test using clinical-grade metabolic cart
