The New Unifying Theory

Dean Ornish, M.D. has directed revolutionary research proving, for the first time, that lifestyle changes can often reverse-undo-the progression of many of the most common and costly chronic diseases and even begin reversing aging at a cellular level.

Medicare and many insurance companies are now covering Dr. Ornish’s lifestyle medicine program for reversing chronic disease because it consistently achieves bigger changes in lifestyle, better clinical outcomes, larger cost savings, and greater adherence than have ever been reported—based on 40 years of research published in the leading peer-reviewed medical and scientific journals.

Now, in this landmark book, he and Anne Ornish present a simple yet powerful new unifying theory explaining why these same lifestyle changes can reverse so many different chronic diseases and how quickly these benefits occur.
