Tanya Halliday, PhD, RD is an Assistant Professor in the Department of Health, Kinesiology, and Recreation at the University of Utah. Her research focuses on appetite and food-intake regulation in response to lifestyle interventions such as dietary restriction and exercise. Currently, she is investigating how type of exercise (e.g. aerobic vs resistance) influences hormonal and behavior indices of appetite regulation, and mechanisms underlying response variation in body mass regulation with exercise. Another current area of research focus is on development of effective weight loss maintenance strategies. Dr. Halliday is also examining how sex as a biological variable, may influence the appetitive responses to energy deficits elicited through both increased exercise energy expenditure and caloric restriction.

Dr. Halliday recently completed an NIH-funded postdoctoral research fellowship in the Division of Endocrinology, Metabolism, and Diabetes in the Department of Medicine at the University of Colorado’s Anschutz Medical Campus. In addition to her research program, Dr. Halliday also worked as a Registered Dietitian in the “My New Weigh” weight loss program run through the Anschutz Health and Wellness Center during her postdoc. She received her PhD in Clinical Physiology and Metabolism from Virginia Tech in 2016, where her research focused on exercise and dietary interventions for the prevention and treatment of obesity and related cardiometabolic conditions. She is also a Registered Dietitian, having completed her BS in Dietetics in 2010 at the University of Wyoming, and her Dietetic Internship through the University of Houston in 2011.
