What we doWorld Obesity Day

World Obesity Day is a unified day of action that calls for a cohesive, cross-sector response to the obesity crisis. It takes place on 4 March and is convened by the World Obesity Federation in collaboration with its global members.

Each year we run a campaign based on a specific theme.  Although World Obesity Day is a point in time, our work continues throughout the year – recognising that different organisations and parts of the world focus their efforts at differing times. 

We aim to increase awareness, encourage advocacy, improve policies, and share experiences. 

Since 2015, World Obesity Days have encouraged people to recognise the root causes of obesity, increase knowledge of the disease, tackle weight stigma, foreground the voices of people with lived experience and act to improve the world’s understanding, prevention and treatment of obesity.

Hundreds of individuals, organisations and alliances contribute to World Obesity Day every year, engaging hundreds of thousands of people across the world.

World Obesity Day 2023

The theme for World Obesity Day 2023 was: ‘Changing Perspectives: Let’s Talk About Obesity'.

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

With important conversations and real stories, we can help people acknowledge obesity's complexities and take effective action. Because when we talk, debate and share, we can shift norms and transform health outcomes.

World Obesity Day 2020

We launched a new World Obesity Day on March 4, 2020, to call for a global response to this critical challenge.

Obesity is now a global crisis that affects 650 million people worldwide, but is poorly understood. The complexity of the disease, the challenge of developing sustainable solutions and the burden of stigma means we need to work together to address the challenge. The most recent World Obesity Day included included global recognition as well as regional and national campaigns and local activities and events. Organisations from across the world acknowledged and celebrated our efforts on 4 March 2020.

Together, we can change the narrative around obesity.

World Obesity Day 2018

For #WorldObesityDay 2018 we focused on raising awareness about the prevalence, severity and diversity of weight stigma. Stigma occurs in a wide variety of settings and the media has been identified as one of the main perpetrators. Current media portrayals of obesity reinforce inaccurate and negative stereotypes about weight which can lead to weight stigma. 

We are calling on all media outlets to end their use of stigmatising language and imagery and instead portray obesity in a fair, accurate and informative manner.

World Obesity Day 2017
