World Obesity Day
World Obesity Day 2026 unites people across the globe to raise awareness and drive meaningful action on obesity.
Convened by the World Obesity Federation in collaboration with its global members, the campaign brings together individuals, organisations, and alliances to highlight the urgent need for improved understanding, prevention, and treatment of obesity.
Previous campaigns have encouraged recognition of the root causes of obesity, challenged weight stigma, increased knowledge of the disease, and shifted attention from individual blame to the broader systems that shape health.
The 2026 Focus: Eight Billion Reasons
This year’s campaign brings together everyone affected by overweight and obesity all 8 billion of us — with particular attention to vulnerable communities, especially children.
Projections suggest that four billion people — half the global population; may be living with overweight and obesity by 2035. At this scale, obesity impacts every community, contributing significantly to non-communicable diseases (NCDs) and widening health inequalities, particularly in low- and middle-income countries.
Obesity is not only a health condition — it is also an indicator of systems that are not working effectively.
The Scale of the Challenge
The global burden of overweight and obesity continues to rise at an alarming rate:
- In 2022, 1 in 8 people worldwide were living with obesity.
- Adult obesity has more than doubled since 1990, while adolescent obesity has quadrupled globally.
- In 2022, 2.5 billion adults (18+) were overweight. Of these, 890 million were living with obesity.
- 43% of adults were overweight and 16% were living with obesity in 2022.
- In 2024, 35 million children under five were overweight.
- More than 390 million children and adolescents aged 5–19 years were overweight in 2022, including 160 million living with obesity.
- By 2035, four billion people — half of the global population — are projected to be living with overweight and obesity.
Action at Every Level
Personal and Community Level
Each of us can help create a world where obesity is understood rather than stigmatised. We can promote prevention from the earliest years, support people living with obesity with dignity, and foster inclusive, supportive environments for children and families.
Policy Level
Governments and decision-makers play a critical role in shaping food systems, urban design, education, and public health policies that enable healthier choices and equitable access to care.
Health Systems Level
Health systems must be equipped to prevent, diagnose, and manage obesity effectively and compassionately. This includes:
- Integrating obesity prevention and treatment into primary health care and universal health coverage frameworks
- Training healthcare providers to deliver person-centred, stigma-free care
- Ensuring equitable access to evidence-based interventions, including nutrition counselling, behavioural support, pharmacotherapy, and when appropriate, surgical options
- Strengthening early screening and intervention for children and adolescents
- Embedding lived experience into service design, evaluation, and policy planning
By strengthening health systems, we move beyond short-term responses toward sustainable, long-term solutions that benefit individuals and societies alike.
