Dr Catenacci earned her medical degree at Yale University School of Medicine and completed her residency in internal medicine at Yale-New Haven Hospital, where she served as Chief Resident. She completed her fellowship in endocrinology, metabolism, and diabetes at the University of Colorado School of Medicine, where she was appointed to a faculty position in 2007; she is currently Assistant Professor of Medicine in the Department of Medicine, Division of Endocrinology, Metabolism and Diabetes. Her areas of clinical focus are in general endocrinology and weight management. Dr Catenacci sees patients half a day per week in a general endocrine clinic at the University of Colorado Anschutz Outpatient Pavilion, where she treats a range of endocrine conditions, including diabetes, thyroid disease, metabolic bone disease, and lipid disorders. She also spends half a day per week seeing patients in a weight management clinic at the University of Colorado Anschutz Health and Wellness Center, where she focuses on individualized behavioral strategies for weight management along with the use of weight loss medications for appropriately selected patients. Dr Catenacci’s primary research interest is in the role of physical activity in long-term weight loss maintenance. She has conducted several studies for the National Weight Control Registry that have provided information on the physical activity and dietary habits of successful weight loss maintainers. She has authored a comprehensive review on the role of physical activity in weight loss and maintenance, published in Nature Clinical Practice Endocrinology & Metabolism. Dr Catenacci has received a National Institutes of Health (NIH) F32 National Research Service Award and an NIH K23 Career Development Award. She is currently the principal investigator for a 5-year NIH-funded interventional trial designed to evaluate whether an exercise intervention timed after diet-induced weight loss (rather than initiated at the same time) improves exercise adherence and long-term weight loss. She has also served as a subinvestigator on several industry-sponsored weight loss medication trials.
