ObesityWeek 2025 Conference Preview – Featuring the Latest in Obesity Treatment and Research Topics

Published: October 08, 2025

The Obesity Society’s (TOS) annual meeting, ObesityWeek, is set to take place from November 4 to November 7 in Atlanta, Georgia. The four-day ObesityWeek annual meeting is an international conference for clinicians and healthcare professionals to gather and learn about state-of-the-art obesity treatment options, the latest clinical research, and policy and advocacy efforts.

Registration for ObesityWeek 2025 is currently open. Three attendance options are available: in-person, virtual, and on-demand.

ObesityWeek features more than 250 speakers, 13 key lecturers, and six different tracks for attendees to follow, if they wish to stick with a particular set of topics. To make event planning easier and to showcase the wide range of topics being presented, we organized the six tracks to each feature a pair of symposia aligned with their designated themes.

The times and dates are accurate as of October 7, 2025. For the most up-to-date schedule, visit the official ObesityWeek website.

November 7, 10:00 AM – 11:30 AM
Description: This session will focus on pre-clinical and clinical studies investigating biological mechanisms that regulate the motivation to exercise, with a specific emphasis on factors that target the brain.

Interventional & Clinical Studies

Precision Exercise in Persons with Obesity

November 4, 3:30 PM – 5:00 PM
Description: This session explores precision exercise for obesity, examining individual variability in exercise responses and the molecular changes induced by physical activity. Experts will discuss current findings and future strategies for tailoring exercise interventions based on molecular profiles to optimize health outcomes.

Obesity and the Kidney: Evidence to Guide Research and Practice

November 5, 10:00 AM – 11:30 AM
Description: This session highlights emerging evidence across the CKD spectrum and explores opportunities for collaboration between nephrology and obesity medicine in both research and clinical care.

Population Health

Thriving in Later Life—Considerations in Obesity Management for Older Adults

November 6, 8:00 AM – 9:30 AM
Description: Attendees will learn how to navigate the unique challenges of obesity management in older adults, including the age-related weight paradox, and explore effective strategies like GLP-1s and 24-hour movement behaviors to improve outcomes while minimizing risks.

Eating Disorders in the Context of Obesity

November 6, 3:30 PM – 5:00 PM
Description: This session will cover screening for eating disorders, with a special consideration for effective screening in those with overweight/obesity, and will also cover the intersection between obesity and eating disorders in children/adolescents and in marginalized populations. This session is a joint collaboration between The Obesity Society and Society of Behavioral Medicine.

Clinical/Professional Practice

Pediatric Obesity Treatment in the Era of Highly Effective Obesity Medications

November 5, 8:00 AM – 9:30 AM
Description: This session addresses barriers such as insurance coverage, provider reluctance, and centralized care, while offering clinical guidance to pediatric providers on delivering effective, evidence-based treatments.

Know the Facts—What You Need to Know About Compounded Obesity Management Medications

November 6, 3:30 PM – 5:30 PM
Description: With rising demand for anti-obesity medications, compounded alternatives are drawing attention. This session examines their potential to improve access, alongside key safety concerns and FDA regulatory policies-giving clinicians the evidence needed to navigate this evolving treatment landscape.

Policy/Public Health

The Science Behind Ultra-Processed Foods—Addiction, Health Effects and Regulatory Efforts

November 6, 10:00 AM – 11:30 AM
Description: From practical definitions of ultra-processed foods to the cutting-edge science of ultra-processed foods, attendees will hear from leading experts who will define UPF, describe their potential addictive properties, and present the latest science on the metabolic and health effects of these foods. Finally, policy experts will present regulatory options for mitigating the potential harms of ultra-processed foods.

Food Marketing—Effects, Interventions, and Legal Considerations

November 7, 10:00 AM – 11:30 AM
Description: Food marketing shapes dietary choices, often targeting vulnerable populations. This session explores its health impacts, policy strategies to reduce harm, and the legal challenges and opportunities in regulating marketing practices.
