As leaders from Southeast Asia gather for the 47th ASEAN Summit, a clear public-health message is being pressed upon the regional agenda: tackle the non-communicable disease (NCD) crisis now, and do so by changing lifestyles.

According to Bernama, the Malaysian Society of Lifestyle Medicine (MSLM) has urged Malaysia, which will chair ASEAN in 2025, to make Lifestyle Medicine a central plank of the bloc’s strategy against the rising burden of chronic disease.

NCDs — including diabetes, heart disease, stroke and other long-term conditions — are imposing a heavy toll across ASEAN. Current estimates place NCDs at roughly 62 per cent of all deaths in the region.

That figure captures lives shortened, quality of life diminished, health systems stretched and economies affected by loss of productivity and escalating care costs. The problem is not only medical.

It is social and economic. It feeds on urbanisation, sedentary habits, unhealthy dietary patterns, tobacco use and rising stress levels. It also reflects gaps in prevention and early-treatment services.

Dr Siva Poobalasingam, founding president of MSLM and chair of the advisory board of the Lifestyle Medicine Global Alliance, argues that Malaysia’s ASEAN chairmanship offers an opportune moment to shift the regional response.

His position is straightforward: Lifestyle Medicine, if embraced by member states, offers an evidence-based, prevention-focused way to reduce NCD incidence and to manage chronic conditions more effectively.

The approach centres on helping patients adopt sustained, healthy behaviours. It stresses six core elements: a predominantly plant-based diet, regular physical activity, adequate restorative sleep, structured stress management, avoidance of harmful substances and nurturing social connections.

Those six pillars are not theoretical. Interventions targeting diet and physical activity, for instance, have long shown benefit in preventing type 2 diabetes and reducing cardiovascular risk.

Sleep and stress, often overlooked in clinical practice, influence metabolic health, immune function and mental wellbeing. Addressing substance use — notably tobacco and excessive alcohol — remains one of public health’s most effective levers.

Social connectedness affects adherence to healthy habits, mental health and recovery from illness. By packaging these elements into a formal clinical and public-health framework, Lifestyle Medicine seeks to move prevention from a peripheral ideal to routine practice.

Malaysia already offers a practical example. The World Health Organisation–Ministry of Health pilot project on Lifestyle Medicine for Remission of Diabetes in Negeri Sembilan demonstrated how lifestyle-focused care can be integrated into primary care settings.

The pilot combined clinical practice, workforce training and policy work. Early results, as reported by practitioners and programme leads, suggested that structured Lifestyle Medicine interventions can achieve meaningful improvements in metabolic markers and, in some cases, partial remission of type 2 diabetes.

That outcome matters: remission reduces the need for medication, lowers complication risk and improves patients’ lives. It also reduces long-term health expenditure when compared with uncontrolled disease.

There are caveats. Pilot projects often reflect high commitment, intense support and focused resources. Scaling such interventions across diverse health systems is challenging. Primary care clinics in many ASEAN countries face workforce shortages, limited training in behaviour-change counselling and resource constraints.

Cultural differences influence diet, family dynamics and approaches to exercise. Urban and rural communities have different access to healthy food, safe spaces for physical activity, and health education. Measuring long-term adherence and outcomes requires ongoing evaluation. Dr Siva acknowledges these limitations and frames them as reasons for regional cooperation rather than reasons for inaction.

MSLM has proposed establishment of an ASEAN Centre for Lifestyle Medicine to address those barriers. The centre would provide technical support for policy development, standardised training curricula, capacity-building for primary care teams, and an evidence hub to collect and share outcomes.

Such a hub could help member states adapt programmatic elements to local contexts, monitor implementation, and quantify cost-effectiveness across different settings. If located in Malaysia, the centre could leverage the country’s pilot experience and existing public-health infrastructure. It would also act as a platform for research collaborations and for mentorship between higher-resource and lower-resource health ministries.

Linking Lifestyle Medicine with the ASEAN Post-2015 Health Development Agenda (APHDA) and the bloc’s emerging post-2025 vision gives the proposal wider policy resonance. Both frameworks prioritise health resilience, universal health coverage and sustainable development — goals that align with prevention-led approaches.

Embedding Lifestyle Medicine into primary care aligns with universal health coverage by shifting care upstream, reducing the need for specialist interventions, and focusing on interventions that are cost-effective over the long term.

Mental health forms a growing component of the discussion. Lifestyle factors strongly affect mental wellbeing. Diet, physical activity and sleep can modify depression, anxiety and cognitive function. Stress management and social support are core to recovery and relapse prevention.

The 5th Malaysian Lifestyle Medicine Conference, scheduled in Kuala Lumpur from 27 to 29 October and themed “Reimagining Mental Health with Lifestyle Medicine”, will convene regional and international experts to explore synergies between lifestyle approaches and mental-health services.

Combining perspectives from psychiatrists, psychologists, primary-care physicians and public-health professionals could yield actionable frameworks for community-level mental-health promotion.

Yet a word of caution is necessary when discussing clinical outcomes. Pilot studies can produce encouraging signals. Randomised controlled trials remain the gold standard for determining efficacy. Longitudinal cohort studies are essential for understanding durability of remission and complication risk over many years.

Behaviour-change interventions often show initial improvements that diminish without ongoing support. Economic analyses must account for intervention costs, training, monitoring and potential shifts in service use. Policy-makers must evaluate both short-term wins and long-term sustainability.

Sceptics may question whether Lifestyle Medicine risks placing responsibility for health solely on individuals, when broader determinants — poverty, food systems, urban planning — shape lifestyles.

The MSLM’s approach anticipates this critique by promoting public-policy measures alongside clinical interventions. Preventive strategies that change environments — making healthy food more affordable, reducing tobacco and alcohol exposure, creating infrastructure for active travel — amplify clinical efforts. Regional cooperation can support policy transfer, shared regulation, cross-border research and pooled procurement for training resources.

The MSLM’s call is both pragmatic and aspirational. Pragmatic because it builds on a tested pilot and on public-health measures already recognised by WHO and other agencies. Aspirational because it imagines a region where primary care routinely prevents disease as a norm, not an exception.

The pathway is neither quick nor easy. Scaling requires political will, funding, workforce development and cultural adaptation. It also requires realistic expectations about timelines and outcomes.

If ASEAN adopts Lifestyle Medicine as a strategic priority under Malaysia’s chairmanship, the benefits could extend beyond reduced NCD rates. Healthier populations tend to be more productive, place lower burdens on healthcare systems and show greater resilience to shocks such as pandemics.

Integrating mental-health promotion with lifestyle interventions can reduce stigma, expand access and improve overall wellbeing. Shared regional investment in training and research can strengthen local capacity and create a knowledge economy around preventive care.

The coming months, with the ASEAN Summit and the Malaysian Lifestyle Medicine Conference, will be telling. Will technical proposals move from concept to funded programmes? Will finance ministries commit resources? Will ministries of health embed Lifestyle Medicine competencies in primary care standards and medical training?

The pilot in Negeri Sembilan shows what is possible. Replicating it across ASEAN will require patience, pragmatism and persistent political advocacy.
