ICO Awards

We present a number of prestigious awards at each International Congress on Obesity to recognise the achievements of well-derserving experts in their fields. Winners are invited to present at ICO as well as receiving a memento of their achievement. Previous awards have included:

Introduced in 1980, The Willendorf Award recognises outstanding clinically oriented research related to obesity.

The André Mayer Award was introduced in 1983 by the UICO (Unione Italiano Contra l'Obesita) for outstanding research in the field of obesity by a younger investigator.

The Wertheimer Award was introduced in 1986 at the International Congress on Obesity in Jerusalem. This is awarded for outstanding basic research contributions to the field of obesity. 

This award was introduced to the World Obesity Awards portfolio in 2006 for outstanding contributions to this field of obesity.

In 2020 a new award in the portfolio was created to acknowledge outstanding achievement in the field of obesity surveillance, prevention and management. In recognition of his expertise and service, it was named after William Philip T James.

Philip James contributed greatly to the efforts in obesity surveillance, the prevention and treatment of obesity, and in founding and leading IASO (International Association for the Study of Obesity), IOTF (International Obesity Task Force) and WOF (World Obesity Federation). 

A new award for youth leaders was introduced at ICO 2022. This award is for outstanding, youth proposed advocacy efforts and solutions to address overweight & obesity.
