Welcome back to Health Unlocked, where we dive deep into the science and strategies behind living a truly healthy, resilient life. In this episode, Jasen Petersen celebrates a milestone of over 50,000 downloads and takes a journey into the hot topic of metabolic flexibility, a concept that’s buzzing in both the health and biohacking worlds but is often misunderstood.
Jasen breaks down what metabolic flexibility really means, moving beyond oversimplified discussions about diets like keto or fasting, and into how our mitochondria, the energy powerhouses of our cells, adapt to different fuel sources. He discusses why adaptability, not just optimization, is crucial, especially when it comes to battling chronic disease and recovering from stress or illness.
Throughout the episode, you’ll learn how metabolic flexibility is lost, why simply burning fat isn’t enough, the pitfalls of “carb-cutting” trends, and why true resilience comes from restoring your body’s ability to seamlessly switch between energy sources. Whether you’re dealing with chronic illness, striving to improve your health, or just curious about how movement, nutrition, and mitochondrial function all connect, this conversation offers plenty of science-backed insights and practical takeaways.
So grab your headphones, get ready for some myth-busting, and discover how you can start cultivating a “salutogenic” (health-promoting) lifestyle, one mitochondrion at a time!

Unlocking the Truth About Metabolic Flexibility: The Building Block for Lasting Health
Are you curious about metabolic flexibility and why it’s gaining traction in health circles? In the latest episode of “Health Unlock: The Power of Salutogenesis,” Jasen Petersen dives deep into the science, myths, and actionable steps behind this trending concept and why it’s much more than another diet buzzword.
What Is Metabolic Flexibility, Really?
According to Jasen Petersen, metabolic flexibility isn’t just about burning fat or adapting to a keto diet. Instead, it’s your mitochondria’s ability to switch smoothly between using glucose (from carbs) and fatty acids (from fats) as fuel, based on what your body needs and the resources available. Imagine your metabolism as a hybrid car: “It can run on gas or electricity, but only if the system can shift between them smoothly,” Jasen explains.
In essence, true metabolic flexibility is a sign of healthy, adaptive cells, not just a measure of performance or a badge of optimized dieting.
Why Losing Your Flexibility Matters
Loss of metabolic flexibility is subtle and often the foundation for chronic health struggles. “The body stops being able to shift those gears and instead cells remain in early danger states for longer than they should,“ Jasen shares. Rather than simply a performance decline, you might notice:
Blood sugar crashes after meals
Persistent fatigue or brain fog
Poor sleep
Low exercise tolerance
Inflammation that lingers
If you’re fasting, doing keto, or working out but still feel stuck, this could be a sign your metabolic flexibility is compromised; your cells just aren’t switching fuel modes as needed.
Carbs vs. Fats: More Nuanced Than You Think
One common myth? That being “fat adapted” automatically means you’re metabolically flexible. While low-carb or ketogenic diets can help recalibrate your metabolism, Jasen cautions that extremes, either constant high carbs or chronic keto, can both cause the system to get “stuck” in one mode. Balance and adaptability, not rigid rules, are key.
Interestingly, the podcast points out that while the modern world mostly struggles with excessive carb dependence, it’s also possible (though rare) for the body to become “stuck” burning only fat, especially with overly aggressive keto or fasting routines.
Actionable Steps to Restore Metabolic Flexibility
Jasen laid out a blueprint that goes far beyond what’s trending on social media. Here are their top tips:
Prioritize Movement
“Modern life keeps our mitochondria fragmented," says Jasen. Consistent movement, from walking after meals to regular resistance training, helps retrain your cells to regain metabolic range and resilience.Use Fasting and Strategic Refueling
Intermittent fasting and waiting for true hunger signals gently pressure your body to switch to fat burning, but should always be balanced with adequate protein and periodic carb refeeds.Optimize Nutrition
Ensuring your body has the necessary nutrients, magnesium, zinc, B vitamins, omega-3s, and more, is critical for your mitochondria to function at their best.Eliminate Processed Foods and Seed Oils
These drive inflammation and signal dysfunction at a cellular level, hampering your body’s ability to recover from stress.Get Sunlight and Quality Sleep
Early morning sun and good nightly rest help anchor your circadian rhythm, which directly influences glucose metabolism and cellular health.Adopt a Salutogenic Lifestyle
Rather than chasing biohacks, the podcast emphasizes cultivating daily habits (like purposeful movement, nourishing food, and restorative self-care) that reinforce your body’s natural healing and adaptability.
The Bottom Line
Metabolic flexibility is so much more than picking the latest diet trend - it’s about restoring your cells’ natural intelligence so you can move, recover, and thrive. As Jasen puts it: “You’re not just running on gas or electric; you want a car that knows when to switch.” Invest in your flexibility, and you’re investing in lasting health.
