Ben Greenfield is a human performance consultant, speaker, and New York Times bestselling author of 13 books, including the popular titles “Beyond Training”, “Boundless” and “Fit Soul”. Former collegiate tennis, water polo, and volleyball player, bodybuilder, 13-time Ironman triathlete, and professional obstacle course racer, Ben has been voted by the NSCA as America’s top Personal Trainer and by Greatist as one of the top 100 Most Influential People In Health And Fitness. In 2014, my NBT co-founder and medical doctor Jamie Kendall-Weed and I appeared on the Ben Greenfield podcast, and to this day people tell me that’s how they learned about Nourish Balance Thrive.  ​For this podcast, Ben and I met up on the UCLA campus during the Ancestral Health Symposium in August to walk and talk about the harmful effects of loneliness and the importance of social connection. Ben shares some of the innovative ways he’s increased connection with others, despite being a self-proclaimed introvert. We talk about some of the downsides of social isolation and the best reasons for opening yourself up to the “messiness” of others.  Here’s the outline of this interview with Ben Greenfield: [00:01:48] Previous podcasts with Ben Greenfield featuring Christopher Kelly: Why Is My Cortisol High Even Though I’m Doing Everything Right?
