Is it time to embed Lifestyle Medicine in undergraduate and postgraduate curricula?Some light at the end of the COVID-19 tunnel may be nearing. Yet, that same light is revealing a larger and longer term burden on our communities. Our educational institutions and health services have not been spared. The pandemic has catalysed the longer standing impact of anxiety, stress and burnout for many frontline health workers and younger people in particular. It has magnified socioeconomic and wider inequalities that are so detrimental to health and well-being.While fiscal responses to the pandemic continue to be debated, there remains a fundamental barrier for the triad of Public Health, Social Care and Health Care resourcing: workforce. The historical absence of strategic workforce planning in the United Kingdom's National Health Services means that without extending (ethically challenging) international recruitment efforts, even substantial injections of finance into health and care economies are stymied by how such monies can be spent.Lifestyle Medicine stands ready to yield a double dividend. First: to leverage self-care and health improvement amid the plethora of contact points that our communities have with public and third sector services. And second: to protect the health of our current and future workforce. While Lifestyle Medicine is no substitute for traditional population-level public health interventions, Lifestyle Medicine is an important and scalable element of the population health armamentarium, not least as systems seek increasingly integrated and preventive approaches to health and well-being. Behaviour change in the form of physical activity has been recently highlighted as a first-line therapy by U.K. health regulators in the management of depression (National Institute for Health and Care Excellent) 2 and many other chronic physical health conditions. The relevance of health behaviours to mitigate communicable disease threats such as the COVID-19 pandemic will be clear in the minds of many. The need for skills in promoting lifestyle changes is endorsed as a core component of U.K. medical training. 3 The specialty of Lifestyle Medicine, often described as emerging, can increasingly be described as maturing. As the American College of Lifestyle Medicine (ACLM) approaches 18 years of age, and the British Society of Lifestyle Medicine (BSLM) enters its seventh year, the global governance of the movement is transitioning too, with a new World Lifestyle Medicine Council. At the same time, consensus is being achieved on the specialty's scope: six pillars of lifestyle and increasingly concrete clinical application such as coaching, behaviour change and group consultations.
