About World Obesity Day

We aim to increase awareness, encourage advocacy, improve policies, and share experiences. Our campaign reached over six million people in 2016,  another eight million in 2017 and with your help can continue to grow year on year.

Global Support for World Obesity Day 2017


/ 11th October is World Obesity Day!

On current trends, 2.7 billion adults worldwide will suffer from overweight and obesity by 2025.

Untreated, obesity is responsible for a significant proportion of non-communicable diseases (NCDs) including heart disease, diabetes, liver disease and many types of cancer.

If we don’t take urgent action to treat or prevent obesity, the annual global medical bill for treating the consequences of obesity is expected to reach US$1.2 trillion per year by 2025.

We call on governments, health service providers, insurers and philanthropic organisations to invest in obesity without delay!


This means investing in…

  • treatment services to support people affected by obesity

  • early intervention to improve the success of treatment

  • prevention to reduce the need for treatment
