About the Founder and Lecturer

Dr. Hans Diehl, DrHSc, MPH, CNS


Dr. Hans Diehl is a Cardiovascular Epidemiologist with a Doctorate in Health Science and a Masters in Public Health Nutrition.

Dr. Diehl is currently the Director of the Lifestyle Medicine Institute in California. He previously directed the research and education programs at the Nathan Pritikin Longevity Center in California and was a post-doctoral research fellow in cardiovascular epidemiology supported by the National Institutes of Health. He was also a post-doctoral scholar at UCLA.

He developed the Coronary Health Improvement Project (CHIP) based on the foundation that according to the U.S. Surgeon General, 75% of all Western diseases have been found to be "lifestyle" related. Dr. Diehl's pioneering efforts with Nathan Pritikin, MD, and Denis Burkitt, MD, have shown conclusively that many of today's diseases are truly reversible through some simple lifestyle changes.

The CHIP program itself was born in the winter of 1988 when Dr. Diehl was invited to conduct a 4-week lifestyle change program in Creston, British Columbia, a community of about 5,000. Four hundred persons accepted the challenge to take responsibility for their health and became charter members of the first CHIP program.

As a best-selling author, researcher, clinician, dynamic speaker, and top-ranking motivator, Dr. Diehl has lectured to corporations and governments and has presented seminars on four continents. Following the Creston experience Dr. Diehl went on to conduct multiple live programs in Canada, India, Australia and the United States. Because he cannot respond to all the invitations for live CHIP programs, Dr. Diehl decided to produce a Video-CHIP series that is being used very effectively in a variety of settings. Edmonton's local CHIP chapter is a product of this effort.

As Dr. Diehl likes to say, "Health is not everything, but without it, everything is nothing."

Peer Review:
"I would like to take this opportunity to recommend Dr. Hans Diehl, who throughout his life has been a keen worker on the health maintenance side of medicine. Through his writings and seminars he has brought a very powerful message to all who would listen on how to use diet, exercise, and reflection on the more important things in life, to prevent the number one killers in our society – the atherosclerotic diseases such as heart attacks, strokes, peripheral vascular diseases and cancer."
– William Castelli, MD, National Institutes of Health, and Former Director - Framingham Heart Study

"You deserve the highest possible commendation for the wonderfully successful way you and your co-workers carried out the Cornwall CHIP program. You have shown in a magnificent way how people can dramatically improve their health by altering their lifestyle instead of resorting to drugs, high technology and surgery. I have nothing but boundless admiration for what you have accomplished. I know of no one who has accomplished more in the field of disease prevention and health promotion than you."
–Denis Burkitt, MD, discoverer of Burkitt’s lymphoma, and the promoter of dietary fiber.
