Philosophy - The Schwarzbein Principle

“The degenerative diseases of aging are not genetic; they are caused by metabolic imbalance.” – Diana Schwarzbein, MD

First articulated in the late 1990s, The Schwarzbein Principle is notable for its departure from conventional thinking, its solid grounding in science, the degree to which it has since been validated by published research and clinical data, and the extent to which it has been embraced by physicians, other healthcare providers, and the general public.

In the late 1990s, the idea that degenerative disease is substantially preventable through proper nutrition and lifestyle habits and by keeping all hormone systems balanced, was definitely new thought. In response to numerous challenges to her principle, Dr. Schwarzbein has convincingly demonstrated its scientific grounding and validated its truth through her clinical experience with several thousand patients.

Since then, a growing body of research and clinical data now provides further support for her position. The Schwarzbein Principle is central to the orientation and practices of the fast-emerging schools of integrative and functional medicine. The Schwarzbein Principle books are required reading for numerous medical education courses.

By practicing what she teaches – by focusing on nutrition and lifestyle habits and ensuring the balance of all of the hormone systems of the body – Dr. Schwarzbein consistently restores her patients’ metabolic balance and resolves myriad medical conditions with an exceptionally low reliance on prescription drugs. Evidencing the truth of The Schwarzbein Principle, the incidence of degenerative disease among her patients is also exceptionally low.


The publication of her groundbreaking first book, The Schwarzbein Principle, in 1999, established her as an authority in the emerging fields of metabolic health and integrative medicine.  Since then she has been a frequent and favorite lecturer to physicians and other healthcare providers regarding metabolic health, including the management of menopause, diabetes, thyroid, and adrenal health issues. 

Along with The Schwarzbein Principle, her subsequent, best-selling books, The Transition and The Program have made her thinking and practices available to an appreciative worldwide audience.
