    Biography

    Ania M. Jastreboff, MD, PhD is an Associate Professor in Medicine and Pediatrics at Yale School of Medicine. Dr. Jastreboff is a clinically active physician-scientist and international thought leader in the scientific development and clinical application of novel anti-obesity pharmacotherapeutics revolutionizing obesity treatment. As founding director of the Yale Obesity Research Center (Y-Weight), she is leading and shaping pivotal landmark studies of dual- and triple-receptor hormone agonists and NIH-funded studies investigating the physiology of obesity. She has served as lead investigator and author for trials investigating novel nutrient-stimulated hormone (NuSH)-based therapies for obesity including dual hormone receptor agonist, tirzepatide, a GIP/GLP-1 receptor agonist (Jastreboff, et al., NEJM, 2022 & NEJM, 2024) and triple hormone receptor agonist retatrutide, a GIP/GLP-1/Glucagon receptor agonist (Jastreboff, et al., NEJM, 2023). Trained in both adult endocrinology and pediatric endocrinology, she serves on the Board of Governance for The Obesity Society, as a director on the American Board of Obesity Medicine, developing Obesity Clinical Practice Guidelines, and as co-director of the Yale Center for Weight Management, where she sees patients and teach trainees. She is a highly sought after speaker, teaching internationally, nationally, and locally. She is also a compassionate advocate for patients with obesity, from grass-roots patient groups to interviews with Ms. Oprah Winfrey.

    Clinical Care

    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.”
