Summary
Metabolic health is often simplified to a matter of blood sugar, but at its root, it is a complex system of energy substrate signaling. While many view chronic disease as an inevitable part of aging, a systems-thinking approach reveals that maintaining high "flux"—the capacity to efficiently move and clear energy through the body—is the primary lever for longevity. Without the stimulus of regular movement, even the most optimized diet can fail to prevent the accumulation of metabolic waste that leads to insulin resistance and heart disease. In this episode, we sit down with Greg Mushen, a technologist who turned his engineering mind toward his own biology after conventional medicine failed to address his chronic health issues. Mushen breaks down his "Theory of Flux" and why he believes the key to disease resistance lies in meeting our body's "clearance burden". From studying the activity levels of hunter-gatherer populations to debunking myths about walking and V2 max, Mushen provides a data-driven framework for optimizing health through the lens of evolutionary biology and systems engineering.

Insulin Resistance Reimagined : Why blood sugar is a symptom, not the root cause, and how fat accumulation in the liver and muscle disrupts signaling. The Power of PAL : Why a Physical Activity Level (PAL) of 2.0 is the "golden ratio" observed in disease-free subsistence populations. Walking vs. HIT : De-bunking the idea that you need high intensity to improve V2 max and why the &…
