The American College of Lifestyle Medicine is a professional medical society dedicated to the treatment, reversal and prevention of chronic, non-communicable diseases through the use of a variety of lifestyle interventions. One of the most powerful lifestyle interventions is the application of a whole food, plant-based (WFPB) eating pattern that is based predominantly on a variety of minimally processed vegetables, fruits, whole grains, legumes, nuts and seeds. While many ACLM clinicians recognize WFPB eating as the “north star” of chronic disease treatment, they also recognize that each person is on their own health journey and encourage any progression across the dietary spectrum depicted here. This guide was created to help you move toward the “north star.”
