When Ken Lander disembarked from a plane on December 16, 2016, he lost his breath, stumbled, and couldn't make to baggage claim. When the 430-pound Lander was examined in the emergency room, it was determined that it was a very sick heart that had nearly cost him his life that day. Further tests revealed a 90% blockage in the left descending artery, and severely compromised heart efficiency ("ejection fraction" in cardio lingo). On December 17, 2016, Ken googled "books on heart disease and diet." Of the hundreds of options, he chose the one with the most hopeful title: Prevent and Reverse Heart Disease, by Caldwell Esselstyn, MD.
