The Programme Organising Committee (POC) and the Boards of ASOI, EASO and WOF have worked dynamically together to create a vibrant platform which will bring together colleagues from every area of obesity research, prevention and management. Participants are clinicians, practitioners, physicians, nutritionists, surgeons and researchers – all experts and key opinion leaders in the field of obesity and its related conditions. The ECO-ICO2020 programme will include a mix of plenary lectures, oral communications, poster sessions and symposia.
