In 2010, Eric O'Grey's doctor told him to start looking for a funeral plot because he'd need one within five years.  O'Grey, then 51, weighed 330 pounds, had type 2 diabetes, high cholesterol and blood pressure that was "through the roof." He was on some 15 medications for these ailments, including insulin, Metforim and another drug for his diabetes. But switching to a plant-based diet and adopting a shelter dog would radically transform his health and his entire life.
