Michael Klaper, MD, is one of the world's most eloquent, convincing, passionate, and persistent advocates of a plant-based diet. He's studied the health effects, the environmental ramifications, and the psychological aspects of eating meat and junk food, and can put the most complex science in totally accessible terms. Here's how he explains the vast majority of chronic disease in the Western world: "We're putting diesel fuel in a gas engine." Boom. Simple. Powerful. Inarguable. For the past eight years, Dr Klaper has practiced nutrition-based medicine at True North Health Center in Santa Rosa, California. Come January 2018, he's unleashing his best self into the world of education, sharing his knowledge and passion with medical professionals, medical students, and the public. Once you hear our conversation, you'll be as excited as I am about his unfolding quest.
