Virtual Speaker Series Featuring Barbara J. Rolls - Volumetrics: Feeling Full on Fewer Calories

Volumetrics is a healthy eating plan for weight management based on research conducted at Penn State. In this presentation, Barbara J. Rolls, Professor and Helen A. Guthrie Chair of Nutritional Sciences, will discuss how the density of calories in the foods you eat affects hunger and satisfaction. She will present simple, proven strategies to choose foods that will help you to think positively about what you can eat while managing calories rather than focusing on restriction and deprivation. Barbara J. Rolls received her Ph.D. in Physiology from the University of Cambridge, England. After spending her early research career at the University of Oxford, Dr. Rolls became Professor of Psychiatry at Johns Hopkins University School of Medicine. In 1992, she joined The Pennsylvania State University faculty, where she is Professor and Helen A. Guthrie Chair of Nutritional Sciences. Her studies have demonstrated how characteristics of foods such as variety, energy density, and portion size can influence energy intake and body weight. Dr. Rolls has served as President of both the Society for the Study of Ingestive Behavior and The Obesity Society.
