The American Board of Lifestyle Medicine (ABLM) establishes and maintains standards for assessment and credentialing of physicians in lifestyle medicine. Certification as an ABLM diplomate signifies specialized knowledge in the practice of lifestyle medicine and distinguishes a physician as having achieved competency in lifestyle medicine. The ABLM also manages the certification exams for PhD and Master's level health professionals on behalf of the ACLM and IBLM. The ABLM’s efforts extend beyond individual certification. The board’s influence is felt across healthcare by establishing a global standard for lifestyle medicine and promoting standardized language for lifestyle medicine protocols. By supporting the growth of lifestyle medicine, ABLM ensures that healthcare providers have the tools and knowledge to improve patient outcomes and transform healthcare delivery worldwide. Their work fosters greater recognition and adoption of evidence-based lifestyle medicine practices, creating a healthier future for all.
