2025 Year-end letter from our President and CEO
Dear colleagues, partners, and friends,
As 2025 draws to a close, we reflect on a year that has tested the global health community - and demonstrated our collective resolve to ensure obesity is finally recognised, resourced, and addressed as one of the defining public health challenges of our time.
This year, the World Obesity Federation helped shift the global conversation, bringing obesity out of the margins and placing it firmly at the centre of policy dialogues, health system planning, and international commitments. Whether through landmark policy engagement, strengthened data systems, clinical education, or lived-experience advocacy, the work of our members has been essential in driving meaningful progress.
Changing systems, not individuals
Our 2025 World Obesity Day campaign, Changing Systems, Healthier Lives, reframed obesity not as an individual failing but as a consequence of the political, social, and commercial systems that shape our choices and environments. The campaign reached audiences in 187 countries, supported by a flagship film, regional stories from South Africa, the USA, and Trinidad & Tobago, and dozens of member-led events.
Engagement soared across digital platforms - including nearly 6 million impressions on X, over 2 million on LinkedIn, and hundreds of thousands more across Facebook and Instagram, reflecting a global appetite for a more honest narrative: to improve lives, we must change the environments that make unhealthy outcomes inevitable. World Obesity Day demonstrated that when we speak collectively, we can shift public perception and political priorities at scale.
World Obesity Day
For Half of Humanity: a global call to act
This year also marked the expansion of our For Half of Humanity campaign - a unifying advocacy effort rooted in a profound reality: by 2035, over four billion people will be living with overweight or obesity. That is half of humanity living with a disease still misunderstood, underfunded, and too often ignored in national health strategies.
Through compelling evidence, lived-experience leadership, and coordinated messaging across the UN system and civil society, we helped position obesity not only as a disease in its own right, but as an essential entry point to tackling NCDs, achieving universal health coverage, and advancing health equity. The campaign has laid the foundation for accountability in 2026 and beyond.
OUR CAMPAIGN
A pivotal year for global policy
From the Global NCD Alliance Forum in Kigali, to the UN High-Level Meeting on NCDs, to our record-setting Global Obesity Forum in New York, World Obesity ensured obesity was no longer an afterthought in global health negotiations. Our voices - including those of people living with obesity - helped elevate obesity as a structural and political priority.
The year concluded with a milestone achievement: WHO’s first global guideline on the use of GLP-1 therapies for obesity care, recognising obesity as a chronic, relapsing disease requiring comprehensive, lifelong treatment. This guidance marks a historic shift - one our federation has championed for more than a decade.

Strengthening care, knowledge, and accountability
Across our programme areas, 2025 delivered impact at scale:
SCOPE
SCOPE continued to expand its global reach, supporting clinicians through new masterclasses, national fellowships, and accreditations. Four SCOPE schools were held in India, Chile, Brazil and China, and we reached 701 Certifications and 451 SCOPE Recertifications, making 2025 one of our best years yet.
Demand for specialised obesity education grew at record pace, reflecting a clear shift toward integrated, professionalised obesity care across health systems.

Global Obesity Observatory
The Global Obesity Observatory was accessed more than 2.3 million times by visitors from across the world, reflecting increasing global reliance on our data, policy tracking, and analytical tools.
Comprehensive updates ensured that our data were both timely and accurate, and expansions to our presentation maps and cross-national survey pages enabled users to better make international comparisons.
As countries confront rising prevalence and strained health systems, the Observatory is playing a critical role in guiding evidence-based decisions and accountability.

Our journals
Our journals continued to thrive, with considerable increases in submissions observed across all four journals. Each journal expanded its scientific reach and global relevance while maintaining rigorous editorial standards, setting a benchmark in the rapidly evolving field of obesity research.

MAPPS II
MAPPS II gained significant momentum, moving beyond assessment toward enabling system change. Surveys - now available in 11 languages - are capturing the experiences of policymakers, clinicians, and people living with obesity, helping identify gaps in access and readiness at national, regional, and global levels.
In Spain and South Africa, two roundtables brought together national experts, practitioners and lived-experience organisations, providing a platform to build evidence and exchange perspectives on obesity care and prevention. In 2026, MAPPS will expand its country engagement and activate reform coalitions, creating new opportunities for members to shape policy and transform services.

Our Members
Our membership continued to grow in both size and influence. With 13 new members joining in 2025, we end the year with 124 member organisations in over 125 countries and territories. Three new Trustees were also welcomed to the Board: regional representatives Sherlyn Celone-Arnold, representing North America, and Fabio Trujilho representing FLASO, as well as Member At Large trustee Karen Sealey.
These new additions helped drive policy wins, inform research, and strengthen advocacy from local to global levels - ensuring that the obesity community remains united, credible, and action-focused.
Read MoreTogether, these initiatives strengthened the global obesity ecosystem - enhancing care capacity, embedding accountability, and ensuring that obesity is recognised not as an individual failing, but as a chronic disease shaped by systems. The foundations laid this year position us for the next phase of work, where commitments become implementation and evidence drives equitable change.
Looking ahead: Beyond awareness to accountability
In 2026, we enter the second year of our Three-Year Plan, strengthening national support, advancing the WHO Acceleration Plan to Stop Obesity, expanding MAPPS II, and driving obesity into universal health coverage as a measurable obligation - not an optional aspiration.
The challenges ahead are significant: inequities in access to care are widening, unhealthy food systems continue to undermine health, and stigma remains pervasive. Yet the momentum is undeniable. The world can no longer ignore obesity - and thanks to your efforts, it no longer is.
OUR 3 YEAR PLANA final word of thanks
To our members, partners, advocates, and the thousands of people with lived experience who shape our work - thank you. Your leadership, courage, and conviction are changing how the world understands and responds to obesity.
