Several members and advisors from The Obesity Collective attended the European Congress on Obesity (ECO) in Istanbul from 12–15 May 2026. The following reflections highlight some of the key themes and discussions emerging from this year’s congress. Over 4,500 people registered for the congress, making it the largest ECO yet.  Participants expressed great enthusiasm for the content and discussions at the event. A recurring theme in participant reflections was the shift towards viewing obesity as a chronic, complex disease requiring lifelong and personalised care rather than short-term, generic weight management. Delegates noted growing interest in tailoring treatment to individual biological and social circumstances, alongside a broader focus on long-term health outcomes and quality of life.

Some attendees reflected on the discussions around “food noise” – persistent and intrusive thoughts about food. Presentations suggested that reducing food noise is increasingly recognised as an outcome that matters greatly to people living with obesity, alongside traditional measures such as weight loss.  Participants also reflected on debates about stigma, responsibility and public health policy. Discussions highlighted a growing recognition that obesity is influenced by social, environmental and biological factors, prompting calls for more comprehensive and less judgemental approaches to prevention and care.
