PATHWEIGH reshapes weight care in primary care, reversing population weight gain
Endocrinologist Leigh Perreault led PATHWEIGH, a structured primary-care pathway that dedicates visits to weight management and streamlines workflows to reduce stigma and barriers. In a NIH-funded rollout across Colorado's 56 clinics, a large 18-month trial with 274,182 patients found that population weight gain fell by 0.58 kg and the overall trend shifted toward weight loss, with a 23% uptick in weight-related care and more anti-obesity prescriptions, prompting broader interest from health systems.
