Mark Kaplan

Mark Kaplan is the founder and CEO of HealthTruth and the creator of Neo, the world's first AI built on root cause health science. A former ATP professional tennis player who competed at Wimbledon and received the College Player of the Year award from Arthur Ashe at the 1989 US Open, Mark had a heart attack at 52 that changed everything. After surviving a widowmaker and rebuilding his health without medication, he built HealthTruth with four world-class doctors to fix what medicine will not. UNPLUGGED, his first book, became the #1 Amazon Best Seller in Heart Disease in its launch week. He lives in Stamford, Connecticut.

What does your experience reveal about the gap between the external appearance of health and the internal reality of disease?

The outside is not the inside. I had visible abs and invisible arterial disease. For fourteen years, seven separate blood panels flagged one number and nobody looked deeper. Nobody tested my fasting insulin. Nobody tested my inflammation. Nobody tested my Lp(a). Fitness is what you can see. Health is what is happening in your blood vessels while you sleep. I confused the two for 52 years. So does almost everyone, including most doctors.

How does the shared genetic thread across three generations shape the story's deeper message about inheritance, destiny, and awareness?

Genetics loaded the gun. The system never checked if I was carrying it. My son carries the same genetic markers I do. He was tested at 15. I was tested at 52, on an operating table. That is the entire message. The difference between us is not luck or destiny. It is information, delivered 37 years earlier. Genetics is not a sentence. It is a map. But a map only helps if someone shows it to you before you are lost.

In what ways does the phrase "I was the fittest person in the room, and I was dying" challenge conventional definitions of fitness and wellness?

Fitness measures performance. Health measures biology. A strong serve tells you nothing about your insulin. A fast mile tells you nothing about your inflammation. Our entire culture, including medicine, treats athletic performance as proof of health. It is not proof. It is a costume. Some of the greatest endurance athletes in history died of arterial disease. The engine was magnificent. The fuel lines were corroding the whole time.

How do elite sports and high performance environments sometimes mask underlying health risks rather than reveal them?

Three ways. First, athletes get a pass. Doctors look at a fit patient and stop investigating. Second, athletes are trained to push through symptoms. Fatigue, pain, decline. We treat warning signs as weakness to overcome. Third, performance itself hides dysfunction. You can be insulin resistant and still win matches. The scoreboard says you are fine. Your bloodwork would say otherwise, but nobody is reading it.

What role does curiosity and skepticism play in your decision to question conventional medical explanations and seek alternative answers?

The system gave me two words: bad luck. That is not a diagnosis. That is a shrug. I spent my life in competition, and when you lose a match, you study the tape until you understand exactly why. I applied the same discipline to my heart attack. The terror of not knowing why something happened to you is that you cannot stop it from happening again. Curiosity was not a personality trait. It was survival.

How does the story reflect the tension between trusting medical authority and advocating for personal investigation into one's own health?

I do not tell people to distrust their doctors. I tell them to ask better questions. My doctors were not bad people. They were trained inside a system that manages numbers instead of investigating causes. When I stopped the statin, my cardiologist told me I could die on Monday. That was not science talking. That was the system talking. You are the CEO of your own health. Your doctor is an advisor. Advisors work for you. Ask why. Demand the tests. Get the data.

What does it suggest about the difference between treating symptoms and understanding root causes in chronic disease?

A statin lowers a number. It never asks why the artery was inflamed in the first place. That is the entire difference. Symptom medicine asks what and writes a prescription. Root cause medicine asks why, and keeps asking until the chain ends. My cholesterol was smoke. Insulin resistance, inflammation, and genetics were the fire. We have built a trillion dollar industry around silencing smoke detectors while the house keeps burning.

How might awareness of genetic risk change the way individuals approach prevention, lifestyle, and long term health decisions?

It changes the timeline. Heart disease does not begin at the heart attack. It begins decades earlier, silently. My son knows at 16 what I learned at 52 in an emergency room. He can make forty years of informed decisions I never got to make. Test early. Test your children. Know your Lp(a). Know your fasting insulin. Awareness converts fate into a plan. The event that almost killed me does not have to happen to him.

What does your transformation suggest about the possibility of rebuilding health after crisis, and what does that process require beyond medical intervention?

It requires a reason. Mine was my fifteen year old daughter telling me I was not the father she knew. It requires truth. I could not heal until I understood why I got sick. And it requires ownership. Food, sleep, stress, movement, testing. Nobody does that work for you. Today I am 58, on zero medications, with the metabolic health of a man in his early forties. The body knows how to heal. You have to stop feeding it the things that are breaking it, and you have to want to come back.

At its core, what is the book asking us to reconsider about the meaning of true health, especially in a world where disease can exist silently beneath peak performance?

True health is not the absence of symptoms and it is not the presence of muscles. It is what your bloodwork says when you finally ask the right questions. Disease grows in silence for decades beneath strong, busy, successful lives. The book asks one thing. Stop outsourcing your health to your appearance, and stop outsourcing it to a system that measures one number. Look deeper. Ask why.

The truth heals.
