The Global Obesity Forum 2025 is an exclusive, high-level event hosted by the World Obesity Federation, in partnership with WHO and UNICEF as part of the Global Obesity Coalition. Taking place ahead of the UN Fourth High-Level Meeting on Non-Communicable Diseases (NCDs) and Mental Health, the Forum will bring together global leaders, experts, advocates, and individuals with lived experience of obesity to chart a path forward in addressing one of the world’s most urgent public health challenges.

Obesity is a major, yet under-addressed global health crisis affecting 1 billion people across the world, contributing to a range of health conditions such as diabetes, hypertension, and cancer. With nearly 4 million deaths annually linked to obesity, we are at a turning point where urgent, multisectoral action is needed. The Forum will serve as a catalyst for bold, collaborative solutions - from food systems and nutrition to health equity, innovation, and human rights - and deliver a double dividend that can generate health and economic gains while targeting the root cause of multiple diseases.
