An avid sportsman – inline skater, mountain biker, snowboarder, jogger, and basketball player – as well as a longtime lover of fresh, healthful foods, Dr. Seth Marquit fits right in with life at the Pritikin Longevity Center.

His own journey to Pritikin is a fascinating story. In his first years as a physician, he saw every day in emergency medicine people who were suffering, and often dying, from heart attacks and strokes. And every day, he was observing that most of these people were overweight, diabetic, smokers, and/or sedentary. “I quickly realized that I wasn’t really helping these people. I was only applying Band-Aids as I ushered them to the cath lab to fix the immediate threat. We all know this is only a temporary fix.”

Many years ago, a close family member suffered a heart attack in his early 50s and died soon after. “At the time, I thought tragedies like these were all caused by bad genes, but now I know they are mostly related to poor diet.”

The real answer to America’s chronic disease epidemic, he determined, is prevention. A healthy lifestyle can give millions of Americans not only a longer life, but a better life – rich in energy and good health. Newly committed to preventive medicine, Dr. Marquit returned to school to earn a graduate degree in Public Health and Preventive Medicine.

His motivation was also personal. A close family member had suffered a heart attack in his early 50s, and died soon after. “At the time, I thought tragedies like these were all caused by bad genes, but now I know they are mostly related to poor diet. My relative ate two hamburgers almost every day and a pint of ice cream every night. He was also a couch potato.”  Studying prevention, therefore, was “an attempt to defuse my own potential time bomb and not follow in the footsteps of my family members.”

Currently, two other major motivators for living well are “my wife and my four-year-old son. He’s our little treasure… I need to stay heart-healthy to be around for both of them.” His wife is an exercise physiologist and a “role model for my son and me.”

Daily at the Pritikin Longevity Center, Dr. Marquit observes the rewards of prevention and lifestyle change. “When I see our guests lose 10 pounds in two weeks and get off their blood pressure and diabetes medications, I feel as good as they do. There is nothing more rewarding than watching a little motivation and hard work pay off in the end. It’s all evident in each discharge visit, in each participant’s smile and aura. This is a permanent fix. This is a fix I’d love to educate all of America about.”
