As a physician assistant, I often work closely with cardiologists. A big part of my role is patient management -- that means careful communication. I need to meet the patient where they're at, and understand their viewpoint before offering tailored advice. One myth that often needs to be dispelled early on is the idea that exercise can somehow cancel out obesity or a poor diet. Patients are often active, but still carry excess weight that contributes to poor heart health. They consume media that reinforces their belief in a "fit and fat" body type. To counteract this misconception, I rely on studies and statistics. The science is clear: While physicality is an enormous benefit to heart health, it's only one piece of the puzzle. Carrying adipose tissue puts strain on your heart that cannot be undone without reducing your body mass. I show them that the research they've been privy too is often misleading and cherry-picked, and introduce them to a body of information rooted in peer review and publication standards. Teaching them to read critically is key -- otherwise, they will continue to be susceptible to articles that confirm their pre-existing biases.
