Performance
decline after 40
is not age.
It is a measurable
metabolic pattern.

ENGAGEMENT PATHWAYS
"We help high-performing women over 40 rebuild the metabolic capacity -- restoring energy, cognitive performance, and long-term health to fuel their ambition."
35 Years of Clinical Precision.
Built for the Demands of Executive Leadership.
Stacy Naugle is a licensed East Asian Medicine practitioner with 35+ years of clinical and lifestyle strategy experience. After three decades in clinical practice and longitudinal research studying longevity traditions across five continents, she founded Executive Metabolism™ to address a pattern she kept observing:
"Brilliant, high-performing women whose metabolic systems had shifted under the compounding demands of sustained leadership and whose physicians reported normal labs, while their energy, cognition, and capacity were measurably declining."
Her clinical lens is East-West integrative. Her delivery is executive-grade, data-informed, and implementation-driven. The Executive Metabolism™ System translates complex metabolic physiology into structured protocols designed for the schedules and cognitive load of high-performing professionals.
Co-Founder Markus Naugle, B.S. Trained in molecular biology at MIT, he brings a systems science foundation that provides the analytical architecture underpinning the firm's protocol design, enabling measurable, reproducible outcomes.
Both are yoga instructors, parents of four children, and world travelers.
We are available for individual or team appearances.
Interview Topics Across
Three Strategic Lanes
Each topic is built around a reframe — not information. Media books tension. These conversations deliver it.
1. The Hidden Performance Ceiling No One Is Talking About
Why the most accomplished women in the room are losing performance capacity, and why it has nothing to do with effort.
2. Why More Discipline Is Making Things Worse
The physiology of pushing through metabolic decline: why the tools that built your career are now working against your biology.
3. Burnout Is Not a Mindset Problem. It Is a Metabolic One.
A clinical reframe of burnout that entirely changes the intervention and why motivation-based approaches consistently fail this high-achievers.
Business, leadership & entrepreneurship podcasts
1. Metabolic Capacity as a Leadership Advantage
A clinical reframe of burnout that entirely changes the intervention and why motivation-based approaches consistently fail this high-achievers.
2.Why High Performing Women Plateau Physically and Cognitively After 40
A systems-level explanation of the biological shift and a structured model for reversing it without abandoning our careers.
3. Energy Systems Behind Sustained Executive Output
What elite performance actually runs on, and the specific metabolic levers that determine how long a female leaders can sustain it.
4. The Insulin Performance Gap: What It Is and Why It Matters to Leaders
An accessible framework for understanding the master performance hormone and its direct impact on focus, decision capacity, and resilience.
5. Performance Decline After 40 Is Not Age. It Is a Measurable Pattern.
How to differentiate normal aging from addressable metabolic dysfunction and what becomes possible when you treat it correctly.
HR, benefits & organizational leadership
4. The ROI of Energy, Focus, and Resilience
Connecting metabolic optimization to measurable business outcomes: cognitive performance, absenteeism, and leadership longevity.
2. Why Women-Specific Metabolic Programs Outperform Generic Wellness
The physiological case for gender-differentiated executive wellness and what organizations are leaving on the table without it.
