4 March - World 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 – recognizing that different organizations 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 recognize 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, organizations, and alliances contribute to World Obesity Day every year, engaging hundreds of thousands of people across the world.
