Rip Esselstyn lives in Texas. He's a firefighter, a triathlete, and author of the book "The Engine 2 Diet", which started out as a 28-day challenge to lower the cholesterol of his fire crew (some with digits in the 340s!), and ended up giving them all (and hundreds of other Austin, Texas firefighters) much more than they bargained for! I chatted with Rip the other day about his book and how it's changing people's lives in under 30 days. We talked about everything from amazing pizza recipes, to boners, sports and manliness.
