This week, we went to Bulletproof to meet with founder Dave Asprey (Twitter: @bulletproofexec), a company you might know best for the "butter in your coffee" craze. But Dave's work, and Bulletproof, are so much more -- they're in the business of "biohacking," or changing your environment inside and out so that you can have the most possible control of your biology.

As an executive at a non-profit for anti-aging research, Dave began to understand the nutritive shortcuts -- the biohacks -- that we can activate for our best health. He started blogging about it on the side, and out of that effort grew the Bulletproof empire.

Listen in as we discuss his new bestselling book, Head Strong, about being the boss of your mitochondria, and about how there's not a lot of convincing science to support coffee enemas… Something we wish we'd known a few weeks earlier.

This Week on Barbell Shrugged, We Interview Dave Asprey to Discuss:

• The concept of biohacking - what it is and how to do it
• The difference between cravings and hunger (and how to shut the cravings down)
• What nootropics are and how they make your brain perform better
• Coffee enemas… That's all we'll say about that right here.
