World Obesity Day 2023

This theme for World Obesity Day 2023 was ‘Changing Perspectives: Let’s Talk About Obesity’. The campaign used conversation and stories to help people correct misconceptions surrounding obesity, acknowledge its complexities, and take effective, collective action. 



Changing Perspectives: Let's Talk About Obesity

Obesity is on the rise globally, with 1 billion people predicted to be living with the disease by 2030. Despite the scale of this epidemic, efforts to address it are challenging due to misconceptions about obesity and the role it plays in a person’s health.

Our goal is to change perspectives: to correct misconceptions - our own and others' -, end stigmas and get everybody making the decision to shift from single views to shared strategies. 

On 4 March 2023, obesity was put squarely on the global agenda as people and communities around the world marked World Obesity Day.

The World Obesity Day (WOD) 2023 campaign aimed to encourage constructive conversations about obesity that could help key audiences challenge stigmas, taboos and misconceptions, share ideas, and work together to find cross-cutting solutions.

Global engagement

Our 2023 campaign focussed on systemic issues, stigma and the importance of talking about obesity. Key website changes including a dedicated youth page and the 'It's on the cards' interactive deck. We developed a wide range of new assets including conversation cards to make talking about obesity easier for everyone. 

In the build up to WOD, we held an online interactive workshop attended by 76 of our members, where they shared plans, ideas and questions.

WOD 2023 saw excellent engagement from obesity groups and, together with World Obesity's accompanying Atlas report, generated record press coverage - achieving its goal to kickstart discussion around the world.

Sharing experiences globally

World Obesity Day is a truly global event that relies on the contributions of hundreds of supporters and organisations worldwide. We were delighted at how many came forward to share their stories and activities: this year saw nearly 150 notices of stories, events, and actions added to the World Obesity Day website. 

We also hosted two webinars around World Obesity Day, and co-hosted one in partnership with the WHO and UNICEF.
