Episode 493: Ben Greenfield: How to Actually Look 20 Years Younger + His Most Extreme Biohacks Revealed

What happens when biohacking's biggest evangelist spends $40,000 replacing his blood with young plasma? In this episode of Habits and Hustle, I sit down with Ben Greenfield, the ultimate biohacker and author of "Boundless," for a deep dive into the science of optimization.  We discuss the real science behind fat loss, his daily skincare routine that keeps him looking decades younger, and why he believes faith is just as important as physical optimization. We also dive into his controversial take on GLP-1 microdosing, why the 12-3-30 treadmill trend is overrated, and how he went from extreme experimenter to finding balance between optimization and spirituality. Ben Greenfield is a biohacker, human performance consultant, and New York Times bestselling author. He's one of the world's leading experts on performance, recovery, sleep, digestion, brain optimization, and anti-aging. His revised book "Boundless" is considered the encyclopedia of health optimization.
