Beyond knowing,
accelerating.
Insights from the “Accelerating the Global Response to Obesity” panel at the 79th World Health Assembly meetings in Geneva, Switzerland.
On 20 May 2026, on the occasion of the 79th World Health Assembly, the WHO Foundation and Eli Lilly and Company co-hosted the “Accelerating the Global Response to Obesity” panel. The session was framed around the WHO Acceleration Plan to Stop Obesity, a panel of national health officials, multilateral and private-sector partners, and regional advocates examining how to close the implementation gap.

The panel agreed that the science and global commitments are already in place. What is missing is delivery at scale: in the primary-care settings where most people are reached, and in the low- and middle-income countries that carry most of the burden. As one speaker put it, obesity remains misunderstood and stigmatized, and must be understood as a disease connected to changing food systems and urbanization requiring a systemic response across both prevention and treatment.
The Acceleration Plan, in brief.
Obesity affects more than one billion people worldwide, most of them in low- and middle-income countries. Adult obesity has more than doubled since 1990; adolescent obesity has quadrupled.
It drives diabetes, cardiovascular disease, and cancer, and is projected to cost the global economy over $2 trillion by 2030 and $4 trillion by 2035.
Recognition is settled; obesity is accepted as a chronic, progressive disease. The WHO Acceleration Plan to Stop Obesity — developed and led in partnership with UNICEF — gives a shared framework. What remains unsettled is delivery. The vast majority of those with obesity never seek treatment, and the work of turning policy into scalable action is fragmented.
Closing the gap between what we know and what we deliver.
The Acceleration Plan was introduced in 2022, aiming to halt the rise of global obesity by 2030. Since then, 34 countries have signed on as front-runners. Each prioritizes interventions, builds a national acceleration plan, and enters a rapid 100-day implementation sprint, with peer learning across regions and continued WHO support. A global stock taking is planned for 2026 to assess progress, with a second wave of countries preparing to learn from the first.
Four pillars:
This panel set out to move beyond commitment to implementation, with a focus on both regional experience and ways to accelerate scaling.
Discussions centered on four pillars: health system response readiness, regional experiences, cross-sector coordination, and how to scale effectively and rapidly. Building on momentum and learnings from the Acceleration Plan, the conversation considered how to turn these lessons into scalable, multi-sectoral implementation.
Health system readiness.
Panelists agreed; our health systems lack trained primary care providers. This goes beyond physicians to include nutritionists, nurses, clinicians, pediatricians, school nurses, OB-GYNs, and community health workers.
Exploring regional experiences.
The conversation featured lessons from Acceleration Plan front-runners. Some lessons are technical: healthy taxes on soft drinks and nutrition labeling. Softer lessons include the challenge of societal bias.
Multisectoral action.
Accelerating the response to obesity is not only about what reforms and levers can be found in public health systems. It requires a multisectoral response that can make changes; food labeling, marketing restrictions, healthy taxes, school programs, agriculture, and culture are all critical levers.
Design for scale, or specificity?
Through it all, one tension: we must accelerate the scaling of programs, but must also recognize the role of cultural norms in obesity.
What we must help depart well:
Obesity’s sticky stigma.
While in some areas, being overweight is a sign of wealth and success, in much of the world there is a stigma that obesity and being overweight is a personal failing, a matter of willpower. A vocabulary of sin and shame (calling sugar levies “sin taxes”) reinforce the notion of obesity as a moral failure, impacting both individual decisions about seeking treatment and policy.
The donor-funded vertical model.
Financing the response to obesity will be different from infectious disease responses, which relied on donor finance. There will be no “global fund for obesity.” Instead, government financing should be at the forefront, funded by things like healthy taxes. Philanthropy and multilateral institutions have leveraging and support roles to play.
Pilots that never scale.
National implementation models are emerging, but obesity care too often stalls at the pilot stage, and progress in translating policy into scalable delivery remains fragmented. The task now is moving from pilot to implementation, and embedding care so it sustains itself.
Health sector on the front lines, alone.
Obesity is bound up with changing food systems and urbanization, which makes it multisectoral by nature. Where primary care is left alone with the problem, it cannot succeed. Food labeling, marketing rules, agriculture, schools, and fiscal policy all have to be in the room.
What we must help arrive well:
Obesity care embedded in primary health care.
Obesity is chronic, and obesity care is best treated as part of routine primary practice, where it is reachable and accessible. Accessibility is key as chronic conditions must be continuously treated, and patients need support to ensure long-term engagement with health systems.
Whole-of-society action.
Warning labels, marketing restrictions, nutrient-profile models, school programs, and messaging campaigns are key components of combating obesity. These take place outside the remit of health systems and deeply reduce demand on health systems.
From pilot to scale, by embedding.
Programs built into existing health system architecture, rather than run in parallel, become self-sustaining. A multi-country NCD pilot succeeded by embedding care in primary systems, growing from 5 to 21 countries on that model.
Sustainable financing via healthy taxes.
Donor-funded models are unsustainable for non-communicable diseases, meaning government finance must lead. This requires reliable revenue, which can come from healthy taxes. Tools such as soft drink taxes are low cost, fast acting, and revenue generating.
Learning the lessons of local realities.
Effective acceleration of the global response to obesity relies on accounting for deeply local realities. Cultural attitudes on body weight, disparities in disease burden, and primary health system capacity restraints are highly localized. Global frameworks provide direction, but success depends on translation into context-specific strategies.
New communication strategies for primary care providers.
Many spend their lives seeing obesity as shameful. Given obesity’s chronic nature, primary care providers expect to have a long-term relationship with their patients, positioning them to help patients shed harmful bias through strategic communication.
Patient advocacy as low-cost infrastructure.
Coalitions of patients at a country or regional level bring together people with lived experience to inform better policy and implementation. Currently, patient advocacy for those living with obesity is rare. Fixing this will help not only improve policy and response, but empower patients to better navigate health systems.
Equitable access to new treatments.
GLP-1 medications are a genuine breakthrough and often the first real option short of surgery. Ensuring access without deepening inequity, and clinically appropriate use rather than fashion-driven demand requires smart policy, sustainable systems, and the inclusion of holistic approaches.
Signal Discernment
These are some of the specific insights and takeaways that stayed with attendees in the weeks following.
On reframing the disease.
Weight is a symptom of obesity; if we are not treating people holistically then even whenwe are achieving weight reduction, we are not addressing obesity itself.
On the burden patients carry to be treated.
This is not going to be mediated as a number of infectious disease responses have been over the last 25 years. There will not be a global fund for obesity…the financing model has to be very different than it’s been in the past.
On stigma and the “sin tax.”
I’ve always found the term ‘sin tax’ reinforces the stigma that it’s a sin to use certainproducts. There are products that do harm, and taxing them creates government revenue.
On scaling by embedding, and the role of trust.
The programs that worked were embedded into the current health system. Once it’s embedded, we find it’s self-sustaining. Community workers fill the gap between the community and the health system, and they build trust, which is often the biggest gap.
On the delivery gap.
Fewer than one in ten people with obesity in low-income countries receive treatment. What we need now is action and collaboration to turn evidence into delivery.
On continuous, compassionate care.
We have to talk about it like we talk about mental health. It is okay that you need a medication for life; it is a chronic, complex disease.
On the role of philanthropy.
The amount of philanthropy that’s out there in the world is enormous. But philanthropy has to play a leverage role. It has to be taking risks, it has to be driving evidence, it has to be acting quickly, but it’s not going to be what’s ultimately funding the response.
On bringing obesity care to the front lines.
The day-to-day experience of someone going into the healthcare system doesn’t involve primary care physicians. OBGYNs, school health nurses, pediatricians, and other front-line primary care providers need to be trained in obesity and how to have these conversations.
