A Global Gathering Advancing Obesity Science
Every year, ObesityWeek brings together leading researchers, clinicians and public health experts to explore the latest developments in evidence-based obesity science — from cutting-edge clinical research to new approaches in treatment, prevention and policy.
At ObesityWeek 2025, attended by more than 4,500 individuals (a significant increase from past years as interest in obesity science continues to rise), OPTAVIA’s Scientific & Clinical Affairs Team (S&CA) — a proud participant of ObesityWeek for more than a decade — joined this global community to share new insights on the future of metabolic health.
With growing recognition of obesity as a chronic disease driven by a mix of genetic, environmental and behavioral factors, this year’s conference emphasized the importance of a comprehensive approach to weight loss that integrates both nutrition and lifestyle. Experts explored how obesity disrupts metabolic health and how science, structure and behavior can help restore balance.
What is ObesityWeek?
ObesityWeek is the annual scientific meeting of The Obesity Society, bringing together a diverse community of health professionals, researchers, clinicians and others who study the causes, consequences and treatment of obesity and associated chronic health conditions. The weeklong event features presentations, discussions and networking opportunities designed to advance understanding of how obesity impacts overall health.
As recognition grows that obesity is a chronic disease requiring long-term, multifaceted solutions — not only pharmacological but also nutritional and behavioral — ObesityWeek serves as an energizing forum for sharing new perspectives on the science of metabolic health and the path forward in obesity care.
How the Conversation Has Evolved
In past years, much of ObesityWeek’s focus centered on weight loss — how to achieve it and sustain it.
In 2025, the conversation expanded beyond the scale. Researchers explored how obesity impacts metabolic function, co-morbidities associated with obesity, sleep quality and long-term health outcomes, and how interventions can address these interconnected systems across the lifespan.
Today, the conversation is broader and more nuanced:
How does obesity alter metabolic function and overall health?
What’s the balance between pharmacotherapy and behavioral changes?
How can we help people not just lose weight, but improve how their bodies function and feel?
What role do healthy habits, like physical activity, sleep and nutrition play in achieving long-term metabolic health?
This evolution reflects a shift toward a more holistic understanding of obesity — one that treats the disease and its metabolic consequences in tandem.
Advancing the Science of Metabolic Health
Backed by more than 40 years of clinical and scientific expertise, OPTAVIA’s scientists and researchers and other experts continue to contribute to the growing body of research on metabolic health.
The team presented two new posters at the conference that explored how obesity medications impact long-term weight loss and the relationship between sleep quality and metabolic health.
Poster Presentation 1: Understanding Long-Term Weight Loss with GLP-1 Medications
“Mind the Plateau: Addressing Long-Term Weight Loss with Anti-Obesity Medications”
This study explored the long-term effectiveness and sustainability of weight loss achieved with GLP-1 medications.* Through a modeling approach, an individual taking 15 mg tirzepatide (the highest dosage) was simulated over a 193-week period.
Findings showed significant weight loss that stabilized around week 96 as the body adapted, driven by increased appetite and caloric intake. After the medication was discontinued at week 176, caloric intake continued to rise, leading to partial weight regain.
The takeaway: While pharmacotherapy such as GLP-1 medications* can jumpstart weight loss, overcoming the weight loss plateau is crucial for reducing cardiometabolic risk and supporting long-term success. Sustainable results depend on an integrated lifestyle approach — including nutrition therapy, behavioral support and self-monitoring — the essential components for lasting metabolic change.
Poster Presentation 2: The Critical Role of Sleep Quality in Metabolic Health
“Associations of Sleep Duration and Quality with Risk of Incident Obesity, Diabetes, and Metabolic Syndrome”
This study explored how sleep duration and quality influence the odds of developing obesity, diabetes and metabolic syndrome in midlife adults across the United States. Using data from the Midlife in the United States (MIDUS) study, the team examined how sleep patterns impacted long-term metabolic health.
The findings revealed that short sleep duration (less than seven hours) was not significantly linked to development of these chronic conditions. However, poor sleep quality (e.g., difficulty falling or staying asleep, frequent awakenings or limited deep sleep) told a different story — it was associated with significantly higher odds of developing obesity and diabetes, emphasizing that how well we sleep may matter more than how long we sleep.
The takeaway: Quality sleep is a cornerstone of metabolic health. While many Americans struggle to get enough rest, this research reinforces that it’s not just the hours that count — it’s getting truly restorative sleep that helps the body regulate energy, manage weight and maintain healthy metabolism over time.

Bringing the Research to Real Life: Metabolic Synchronization™
For more than a decade, ObesityWeek has been a cornerstone event for OPTAVIA’s Scientific & Clinical Affairs Team — a platform to both contribute to and learn from the evolving science of obesity and metabolic health. This continued presence underscores our leadership in advancing scientific knowledge, not only through industry insights but also through real-world application within our comprehensive system.
That commitment is reflected in our latest breakthrough science, Metabolic Synchronization™, which addresses metabolic dysfunction starting with a targeted reset. By improving body composition through a strong and targeted fat burn, helping to reduce bad fat while preserving lean mass, Metabolic Synchronization helps get your body working for you — not against you.
This breakthrough science is about more than weight loss. It’s a framework that helps align the body’s natural rhythms through balanced nutrition, physical activity, sleep and behavioral habits — promoting long-term metabolic efficiency and resilience.
It also guides sustainable lifestyle change through an evidence-based approach to habit formation, taking into account factors like sleep, movement and more.
Looking Ahead: A Healthier Future
OPTAVIA's participation at ObesityWeek 2025 reflects its commitment to addressing metabolic dysfunction at its core through science, structure and innovation.
