SHANON CASPERSON, PhD

Research Biologist

Biography

Dr. Casperson received the B.S. degree in Exercise and Human Performance from the University of Houston, and the Ph.D. in Cell Biology from the University of Texas Medical School, where she studied how nutrition, specifically amino acids, and exercise independently and synergistically contribute to the maintenance of skeletal muscle mass. She joined the staff at the Grand Forks Human Nutrition Research Center as a postdoctoral research fellow in nutrition and obesity. In November 2014, she became a Research Biologist in the Center's Healthy Body Weight Research Unit.

Research Interests

My research focuses on the metabolic role of daily protein intake as it relates to the protein leverage hypothesis and the meal threshold concept. Most Americans consume a skewed diet, in which the majority of their total daily calories and protein intake occurs during the evening meal. In addition, approximately 9% of total calories in the American diet come from sugar-sweetened beverages. This imbalance in the macronutrient composition of the American diet may be responsible for a disruption in the homeostatic regulation of food intake and body weight. My current projects examine how protein intake distribution patterns affect energy metabolism and between-meal snacking and how the inclusion of a sugar-sweetened beverage with meals effects substrate utilization and cravings for high-sugar snack foods.
