For fans of Ben Greenfield, this is Ben like you've never heard him before. For longtime listeners and fans of health & fitness podcasts, Ben Greenfield needs no introduction. Self-avowed training guinea pig, ardent nutrition student, accomplished multisport athlete, podcast host, blogger and health entrepreneur at Ben Greenfield Fitness and all around good dude. Ben and I have been acquainted for some years — but only through the internet. He was an early guest on this show ( RRP #11 ), I have guested on his podcast as well as his Endurance Planet podcast ( HERE ), we did a nutrition-oriented Spreecast with Vinnie Tortorich back in February ( HERE ) and he has written about my exploits a bit as well ( HERE ). And yet surprisingly, we had never met in person. So it was a pleasure to finally sit down with the guy one-on-one so we could dig a bit deeper. Skype interviews are great, but there is just no substitute for sitting across from someone when you want to have a proper chat. And this interview gets it done in spades. Today on the show we talk about a multitude of things, including:

* How he turned his passion for health and fitness into a thriving online business * Some keys for entrepreneurial online success; * His experience training for and racing an Ironman on a high fat / low carb ketogenic diet; * His plan for putting on 30lbs of muscle during the upcoming winter months; * Our experiences interviewing Durianrider; * What the lifestyle “hack” (as in #lifehack or #biohack) actually means; * His experience as a homeschooled child and how he homeschools his children; * How his dietary regimen is often misunderstood, his passion for plants & his vegetable garden; and * Ben's Upcoming Human Performance Course on CreativeLive.

Like many of my guests, I don't agree with all points & issues raised. But I truly like and respect Ben, particularly his willingness to engage in all forms of self-experimentation and his transparency when it comes to openly sharing his results. I hope you enjoy the conversation! Rich
