93% of people are metabolically unhealthy, and it’s not because they’re lazy or eating too much fat. It’s because their bodies forgot how to burn fat at all. This episode gives you a complete roadmap to reboot your metabolism, escape the sugar-burning trap, and reignite your fat-burning engine for good.

Host Dave Asprey sits down with Ben Azadi, functional health expert, best-selling author of Metabolic Freedom, and one of today’s most trusted voices in the ketogenic and fasting space. After reversing his own obesity through biohacking and functional medicine, Ben has helped millions unlock metabolic flexibility and master human performance through smarter-not-harder strategies.

They explore how high insulin, not fat or salt, drives most chronic disease, and why your doctor probably isn’t testing for it. You’ll learn the truth about seed oils, fructose, and blood sugar spikes, and why most people using continuous glucose monitors are still missing the real metabolic threat.

You’ll also discover how to:

• Switch out of sugar-burning mode and back into fat-burning ketosis

• Use fasting, cold therapy, and sleep optimization to repair mitochondrial damage

• Fix hidden nutrient deficiencies with the right supplements, potassium, and electrolytes

• Build real metabolic resilience with Danger Coffee, functional medicine, and nootropics

• Avoid the trap of endless keto or carnivore and learn how to cycle your way to true metabolic freedom

• Understand why low HRV, high insulin, and sleep debt crush longevity, energy, and brain optimization

• Decode how neuroplasticity, emotional regulation, and resilience all connect to metabolism

This is your science-backed guide to transforming your energy, losing stubborn fat, and becoming metabolically unstoppable.
