Dr. Williams, started eating a vegan diet in March of 2003. A heart patient with very high-risk findings in inspired him to try a plant-based diet. The patient initially had a heart condition that was a severe, three-vessel disease pattern of reversible ischemia. She came back to him several months later after she'd been following Dr. Dean Ornish's Program for Reversing Heart Disease. This includes a plant-based diet, exercise, and meditation. She told him her chest pain had resolved in about six weeks on the program. Her heart scan had also become essentially normal.
