A new weight management program called PATHWEIGH, implemented in primary care clinics, has demonstrated significant success in halting population weight gain and increasing access to obesity treatment, according to a study released January 17, 2026, by the University of Colorado School of Medicine. The program, developed with the help of Colorado endocrinologist Leigh Perreault, MD, offers patients a clear pathway to medical support for weight management and equips doctors with the tools to dedicate entire visits to weight care.
The PATHWEIGH system allows patients to openly request help with weight management, removing the stigma often associated with the topic. Instead of generalized recommendations, the program provides access to specific medical interventions and support systems. This includes detailed dietary guidance, exercise plans tailored to individual needs, and, when appropriate, prescription medications.
"For a long time, I felt uneasy about how weight management was handled in routine medical care," said Dr. Perreault. "Too often, patients were sent home with the same advice to eat better and exercise more, which is rarely effective without proper support and resources."
The program's effectiveness was demonstrated in a large-scale, real-world trial. The results showed a halt in population weight gain among participating clinics, a significant achievement considering the ongoing obesity epidemic. Furthermore, the trial indicated a substantial increase in the number of patients receiving medical treatment for obesity.
The PATHWEIGH program is designed to integrate seamlessly into existing primary care workflows. It provides doctors with standardized protocols and resources, enabling them to address weight management effectively during routine appointments. This approach contrasts with traditional methods, where weight concerns are often addressed briefly or not at all due to time constraints and lack of specialized training.
The success of PATHWEIGH is generating considerable interest from health systems across the United States. Several organizations are currently in the process of adopting the program, with plans to implement it in their primary care clinics. The University of Colorado School of Medicine is providing training and support to facilitate the widespread adoption of PATHWEIGH.
Experts believe that PATHWEIGH represents a significant step forward in addressing the public health challenges associated with obesity. By integrating weight management into routine primary care, the program has the potential to reach a large number of individuals and improve overall health outcomes. The program's focus on patient empowerment and evidence-based interventions is seen as a key factor in its success.
