On behalf of the Society’s conference organizers, program chairs, volunteers, staff, and leadership, we welcome you to ObesityWeek 2026! Whether you are attending in person or following along through our daily conference updates, we are honored to have you join us.

At ObesityWeek, we come together as professionals across the fields of obesity science, united in our commitment to moving science and practice forward through meaningful, multidisciplinary collaboration.

Building on this momentum, the ObesityWeek 2026 program features more than 175 scientific sessions, more than 250 expert speakers, and numerous daily activities to network and recharge with colleagues from across the globe. Our conference app (download the EventPilot Conference app for your Apple or Android device) makes it easier than ever this year to make connections, so be sure to download it and take advantage of all the features.

With strong registration from professionals based in the United States and internationally, ObesityWeek 2026 is on track to set an attendance record and provide thought-provoking experiences in Key Lectures, symposia, oral sessions, award presentations, poster sessions, workshops, and informal conversations throughout the conference.

With so many session opportunities, attending every event of this robust program is simply impossible. You can plan your days by reviewing the online schedule or using recommendations from the conference app’s personalized agenda planner.

Daily emails from The Obesity Society News and updates at TheObesitySocietyNews.org website will preview important upcoming events and recap impactful sessions. You can receive online access to all recorded sessions, beginning in January 2027, by purchasing OnDemand separately or as a registration add-on.

Guided by our commitment to data-driven science, non-stigmatizing language, a culture of care, and the ObesityWeek Code of Conduct & Conference Policies, TOS has worked diligently to create an environment that supports education, cutting-edge science, collaboration, and better lives for people living with obesity.  As a personal favor, I would like to ask everyone to join me in supporting the End Weight Stigma Campaign by taking the pledge whether you are at the meeting or keeping in touch through the daily news.

Sharing knowledge creates opportunities for everyone in our community. At my home institution, I teach an endocrinology course, so I understand the hormones that regulate food intake. However, the more I learn, the more I realize that hormones are only a small part of understanding food consumption. Numerous other factors must be considered, including complex neuronal circuitry. When one node is knocked out or silenced, others often compensate, making it a real challenge to establish clear, causal roles.

That is just one example of how obesity researchers with diverse topic expertise can work collectively to unravel the complexities at the core of understanding this complex metabolic disease and how we benefit from exchanging information and exploring ideas that intersect with or go beyond our own areas of expertise.

This is the power of ObesityWeek: gathering in person, exchanging knowledge, and forging and sustaining professional connections. Plus, some fun parties!

See you in the sessions and at the events!
