Scaling lifestyle medicine across large health systems

“I saw patients actually start to get healthier, which is something I honestly hadn’t really seen in my practice before.”

— Dr. McMacken

How lifestyle medicine can be implemented and scaled in public healthcare

Integrating lifestyle medicine into large, traditional healthcare systems can feel daunting, but it is both feasible and impactful. In this expert interview, Dr. McMacken shares how her early exposure to lifestyle medicine transformed her clinical practice and ultimately led to the development of systemwide programs within New York City’s public healthcare system. By focusing on patients’ lived experiences and therapeutic lifestyle interventions, she began to see improvements in health outcomes that were often missing from conventional care models.

Dr. McMacken reflects on the early pilot program launched at Bellevue Hospital, where demand quickly exceeded capacity. Even in its initial feasibility phase, the program demonstrated measurable clinical improvements, including reductions in hemoglobin A1c, cholesterol, blood pressure, and weight. These outcomes, paired with strong patient engagement, underscored the value of lifestyle medicine as an evidence-based approach capable of addressing chronic disease at scale.

The interview also explores what it takes to expand such programs across a large health system. Dr. McMacken emphasizes persistence, clarity of purpose, and long-term commitment as essential factors in driving change. Today, lifestyle medicine programs are available across all five boroughs of New York City, accessible regardless of ability to pay. She highlights how this approach not only improves patient outcomes and quality of life but also restores professional fulfillment for clinicians, demonstrating the transformative potential of lifestyle medicine within complex healthcare systems.
