Extreme Endurance's Lasting Impact

In this powerful and deeply personal conversation, Darin sits down with Hagen Thiers to unpack one of the most misunderstood journeys in health: why doing "everything right" still doesn't always work — and how true transformation requires decoding the body's survival signals, not fighting them.

Hagen shares his remarkable physical transformation after decades of extreme metabolic adaptation, chronic gut inflammation, and stress-driven physiology. Together, they explore metabolism, inflammation, hyperbaric oxygen therapy, protein intake, discipline, and why sustainable health is built through patience, self-leadership, and listening to the body's intelligence.

What You'll Learn in This Episode

• Why extreme dieting and endurance stress can permanently slow metabolism

• How survival adaptation can block fat loss despite "perfect" habits

• The overlooked role of gut inflammation in weight retention

• Why fat is a protective organ, not just stored energy

• How leptin signaling and inflammation dictate fat loss resistance

• The difference between calorie math and biological reality

• Why healing must precede weight loss for many people

• How protein intake preserves muscle during fat loss

• Why discipline beats motivation every time

• The role of hyperbaric oxygen in reducing inflammation and restoring function

• How oxygen delivery impacts fat tissue, gut health, and recovery

• Why consistency over months—not hacks—creates lasting change

• How physical freedom directly impacts happiness and life quality

Key Takeaway

True health isn't about forcing the body to change — it's about creating the conditions where the body finally feels safe enough to let go.
