World Obesity Day 2026
World Obesity Day 2026 takes place on 4 March, uniting people worldwide to raise awareness and drive action on obesity.
Convened by the World Obesity Federation in collaboration with its global members, it brings together individuals, organisations, and alliances to highlight the urgent need for understanding, prevention, and treatment of obesity.
This year, the campaign brings together everyone affected by overweight and obesity - all 8 billion of us - with a particular focus on our most vulnerable communities: children. World Obesity Day 2026 is a call to action for everyone.
