I reviewed a curated set of 2025 papers on https://pubmed.ncbi.nlm.nih.gov/ on lifestyle medicine and the pattern is clear: lifestyle approaches are everywhere — but not evenly distributed.

Top themes in 2025 publications

• Nutrition — dominates the literature, driven by obesity, GLP-1-era practice guidance, culinary medicine and nutrition-first diabetes guidance.
• Social connections — growing attention to social and spiritual dimensions, mental health links, and community-based models.
• Physical activity — consistently emphasized across obesity, cardiovascular and diabetes guidance.
• Stress management & Sleep — increasingly present in clinical guidelines and assessments (behavioral health and recovery are gaining traction).
• Substance use, Environment, Sexual health & fertility — discussed less frequently but appear in important niche areas (e.g., preconception/PCOS, menopause, and environment/planetary health in pediatric and older-adult pieces).

The United States remains the global hub for LM research, accounting for more than half of all affiliations, followed by a growing European and Asian presence — notably Italy, the UK, India, and China. The expansion of centers like Fuwai Hospital’s Lifestyle Medicine Initiative (China) and the American College of Lifestyle Medicine (ACLM) signals global institutionalization.

So, Lifestyle Medicine is no longer an alternative — it’s becoming the foundation.
