Lifestyle Medicine: New Research Highlights Benefits for Patients and Healthcare Professionals
Recent research is underscoring the broad applications of lifestyle medicine, revealing its potential to both improve patient outcomes and alleviate burnout among healthcare professionals. One study demonstrates the feasibility and safety of reducing glucose-lowering medications in type 2 diabetes patients within a primary care setting, while another investigates how practicing lifestyle medicine can mitigate burnout among clinicians.
Diabetes Medication Reduction: A Primary Care Success
A retrospective chart review, published in the Journal of Clinical Medicine, analyzed electronic health records from 650 adults with type 2 diabetes receiving care at two primary care practices that integrate lifestyle medicine principles into routine visits.
The study identified 41 confirmed cases, representing approximately 6.3% of patients, where diabetes medications were safely reduced or discontinued. These reductions followed documented improvements in weight and blood glucose levels. Researchers observed these significant changes occurring during routine primary care encounters, meaning patients did not require intensive lifestyle interventions, specialty clinics, or structured medication reduction programs. Patients simply needed at least two clinical encounters for inclusion in the review.
If replicated nationally among the approximately 38 million Americans with type 2 diabetes, a 6% deprescribing rate could affect millions of patients, potentially reducing medication burden, treatment costs, and the risk of medication-related side effects.
Among patients who underwent deprescribing and had follow-up data available, average body mass index (BMI) decreased by 2.2 kg/m², and average blood glucose levels fell by 50.5 mg/dL. Both changes were reported as statistically significant. Common medication adjustments included a 34% metformin dose reduction, 19.5% metformin discontinuation, and 19.5% insulin dose reduction. While three adverse events were noted, none were attributed to the deprescribing process within this lifestyle-informed primary care context.
Lifestyle changes, primarily dietary modifications and increased physical activity, were explicitly documented in just over half of the deprescribed cases. Researchers suggested this might underestimate actual lifestyle engagement due to documentation practices. Micaela C. Karlsen, PhD, MSPH, ACLM Senior Director of Research and Quality, emphasized the potential for future research to further examine deprescribing outcomes following lifestyle medicine–informed care and advance patient-centered care through responsive deprescribing protocols.
Combatting Burnout: Lifestyle Medicine's Role for Healthcare Professionals
A separate study, "Using Lifestyle Medicine to Treat Patients Can Reduce Practitioner Burnout: A Descriptive Model Derived from Healthcare Staff Interviews," published in BMC Health Services Research, suggests a compelling link between treating patients with lifestyle medicine and reduced burnout among healthcare professionals.
The research involved in-depth interviews with 41 healthcare professionals and administrators from five U.S. health systems with implemented lifestyle medicine programs, revealing increased job satisfaction following their adoption of lifestyle medicine.
Interviewed participants frequently cited factors such as meaningful patient improvements, enhanced patient empowerment, stronger patient relationships, and a better alignment between their professional values and daily clinical tasks. The interviewees represented diverse roles, including physicians, nurses, nurse practitioners, dietitians, psychologists, health coaches, and administrators.
Burnout, characterized by emotional exhaustion, cynicism, and decreased professional efficacy, is a prevalent issue among healthcare professionals. It is associated with lower care quality, reduced patient satisfaction, and higher staff turnover. Common causes include administrative burdens, inefficient systems, heavy workloads, and a perceived loss of professional autonomy.
The study identified specific factors that may contribute to mitigating burnout, including:
- Observing patient health improvements
- Increased patient satisfaction
- Fostering supportive colleague relationships
- Appreciation for organizational support
- Improved staff health through personal application of lifestyle medicine principles
Researchers subsequently developed an explanatory model connecting these identified factors to the three core dimensions of burnout. This model suggests that lifestyle medicine may reduce exhaustion, lessen detachment or cynicism, and reinforce clinicians' sense of professional accomplishment. Many participants expressed that lifestyle medicine reflected the type of care they initially aspired to practice upon entering the healthcare field, with witnessing patient improvements often restoring a sense of purpose and effectiveness for clinicians.
While acknowledging that lifestyle medicine cannot resolve structural issues such as excessive workloads or documentation, the study concluded that organizational adoption of lifestyle medicine may serve as a promising systems-level approach benefiting both patients and healthcare practitioners. Dr. Bruce Weeks, the lead author, noted the restoration of purpose for clinicians, and Dr. Micaela Karlsen highlighted how meaningful patient outcomes and value-aligned care may help restore professional joy in healthcare.
Understanding Lifestyle Medicine
Lifestyle medicine is a recognized medical specialty that utilizes therapeutic lifestyle interventions as the primary approach for treating chronic conditions such as cardiovascular diseases, type 2 diabetes, and obesity. Certified lifestyle medicine clinicians are trained to apply evidence-based, whole-person, prescriptive lifestyle changes.
The six pillars of lifestyle medicine include:
- A whole-food, plant-predominant eating pattern
- Physical activity
- Restorative sleep
- Stress management
- Positive social connections
- Avoidance of risky substances
These pillars also contribute significantly to the prevention of these conditions.
