Bulletproof founder Dave Asprey talks about his latest book Fast This Way: (How to Lose Weight, Get Smarter, and Live Your Longest, Healthiest Life with the Bulletproof Guide to Fasting).  He discuss why diets and New Year's resolutions never work, the difference between fasting and dieting, and why science is just starting to take intermittent fasting seriously.  He shares how fasting can reduce inflammation, increase your sharpness and productivity, boost your immune system, and even add years to your life.  Dave also reveals how four days alone in a cave opened his eyes to benefits of fasting, why every major world religion still has some form of ritualistic fasting, and why he is now embracing something called a dopamine fast.  Plus how the most famous biohacker is protecting himself from Covid-19, why you always want to start your day with a cup of coffee, and why you finally have  permission to never eat kale again!
