Biography

Ania M. Jastreboff, MD, PhD is an Associate Professor in Medicine and Pediatrics at Yale School of Medicine. She serves as the director of the Yale Obesity Research Center (Y-Weight) and the co-director of the Yale Center for Weight Management. She is trained in both adult endocrinology and pediatric endocrinology, is an obesity medicine physician-scientist, and an international leader in research and clinical application of anti-obesity pharmacotherapeutics. Her work has included working to develop Obesity Clinical Practice Guidelines (AACE/ACE 2016), serving on the Board of Directors for the American Board of Obesity Medicine, educating the next generation of Obesity Medicine physicians by teaching at national and international obesity treatment courses, and conducting cutting-edge clinical-translational obesity research. Her research includes large, multi-center clinical outcomes trials using novel anti-obesity pharmacotherapeutics and studies examining the neurobiology underlying obesity and mechanisms of anti-obesity medications (supported by the NIH/NIDDK). Recently, she has served as lead author for trials investigating potential novel nutrient-stimulated hormone-based therapies for obesity including dual hormone receptor agonist tirzepatide (NEJM) a novel GIP/GLP-1 receptor agonist (Jastreboff, et al., NEJM, 2022) and triple hormone receptor agonist retatrutide (NEJM) a novel GIP/GLP-1/Glucagon receptor agonist (Jastreboff, et al., NEJM, 2023). Dr. Jastreboff thoughtfully advocates for compassionate care for patients with obesity and was recently interviewed Oprah.

Overview

Ania M. Jastreboff, MD, PhD, is an adult and pediatric endocrinologist with expertise in obesity medicine and weight management. She cares for patients who have prediabetes, insulin resistance, metabolic syndrome, and type 1 and type 2 diabetes.

Dr. Jastrebroff, who is director of the Yale Obesity Research Center (Y-Weight), says she empathizes with patients who struggle to lose weight or maintain weight loss. “Carrying excess weight and having obesity is not a lifestyle choice. Obesity is a chronic disease and should be treated with the same vigor and integrity as other chronic diseases,” she says. “We are in the infancy of our understanding of the mechanisms that underlie obesity. Many novel treatments are under development, including new anti-obesity medications, endoscopic procedures, and the refining of behavioral and surgical interventions.”

An assistant professor of medicine (endocrinology) and of pediatrics (endocrinology) at Yale School of Medicine, Dr. Jastrebroff says one of her goals is to conduct clinic research that will lead to better treatments for obesity and also have a clear public health impact in mitigating the obesity “pandemic.”
