Heart disease continues to be the world’s silent killer, claiming nearly 18 million lives every year. Yet, according to leading cardiologist Dr. Pradip Jamnadas, the problem does not begin in the arteries—it starts much earlier, in everyday habits we often overlook. Speaking with Steven Bartlett on The Diary of a CEO podcast, the Florida-based specialist broke down the subtle signals the heart sends long before disease strikes—and why medicine alone may never be enough to prevent it.
The world’s top killer—and why doctors can’t fix it alone
After treating over 30,000 patients in a career spanning 35 years, Dr. Jamnadas, who serves as the founder and medical director of Cardiovascular Interventions, shared a sobering realization. Despite performing countless life-saving procedures, he noticed the same patients often returned with recurring heart problems.
“Medicine can save lives, but it can’t stop the cycle,” he told Bartlett. “People come back because the root causes—poor diet, sedentary living, and chronic stress—remain unaddressed.”
The veteran cardiologist, who also teaches at the University of Central Florida College of Medicine, emphasized that understanding these lifestyle triggers is as important as any prescription.
When your belly talks, your heart listens
Dr. Jamnadas began with a visual cue most people dismiss—the protruding belly. “If you have a belly sticking out, you have a problem,” he explained in the podcast clip shared on The Diary of a CEO’s official Instagram page. The fat stored around the abdomen, called visceral fat, is particularly dangerous because it surrounds internal organs and fuels inflammation.
“This is the epidemic we face today,” he warned. “Frequent consumption of carbs, sugar, and processed foods keeps insulin levels high, leading to insulin resistance—and that’s a direct path to heart disease.”
The forgotten power of fasting
His prescription, however, isn’t a new pill or a complex diet—it’s fasting. Dr. Jamnadas described fasting as a natural mechanism the body has “forgotten” due to modern lifestyles.
“After 12 hours of fasting, your body starts pulling fat out, and the first place it comes from is visceral fat,” he explained. “But with constant snacking and late-night meals, we’ve lost this physiology.”
The cardiologist advocates intermittent fasting not just for weight management but as a way to reset metabolism and reduce cardiovascular risk factors.
The hidden culprits in your daily routine
Beyond diet, Dr. Jamnadas highlighted a list of everyday habits and environmental factors quietly undermining heart health. Among them:
Bartlett, after hours of conversation, called him “one of the most in-demand voices in medicine” for a reason—he blends decades of clinical insight with clarity that can change how people see their own health.
Listening to your heart before it screams
The message from Dr. Jamnadas is practical: heart disease doesn’t begin in the heart—it begins in the lifestyle. Bad breath, belly fat, fatigue, or even sleepless nights could be your body’s subtle distress signals.
The cure, he believes, isn’t just in hospitals but in homes—in how we eat, move, and rest. “We can stop heart disease before it starts,” he said. “But first, we must learn to listen to the signs our bodies have been sending all along.”

Beyond diet, Dr. Jamnadas highlighted a list of everyday habits and environmental factors quietly undermining heart health. Among them:
- Overdoing aerobic workouts: “People who only focus on long-duration cardio often develop more coronary artery disease than those doing resistance training or short sprints,” he noted.
- Mold exposure: “Nearly 70% of homes have some level of mold toxicity, which can damage cardiovascular function.”
- Sleep deprivation: “Even one bad night of sleep can make you insulin resistant the next day,” he cautioned.
- Common foods like white rice: “You’d be surprised how much arsenic there is in rice these days—it’s slow poisoning.”
