Dave Asprey is an incredible author, entrepreneur, and expert biohacker. His Bulletproof coffee is now available in coffee shops around the country, and his book The Bulletproof Diet is a bestseller. Full disclosure: he's also one of my best friends, and I can't imagine anyone more qualified to talk about how to pursue a productive, fulfilling life. As Dave worked to lose over 100 pounds, he learned about the important role healthy fats play in upgrading your brain, your relationships, and your goals. Dave is with me today to explain what qualifies as healthy fats, how to incorporate them into your diet, and why they're key to getting the most out of your day. You're going to love this guy!
