Jessica McNeil

Dr. McNeil’s research primarily focuses on the study of modifiable risk factors (e.g. exercise, diet, sleep) that impact eating behaviors and components of the energy balance. Her studies have included healthy individuals, as well as clinical populations living with chronic diseases such as obesity and cancer. Her work has used randomized controlled and crossover trials to assess the impact of dietary, exercise or sleep manipulations on components of the energy balance. Her studies have also included objective measurements of sleep quality (polysomnography), energy intake (ad libitum meal intake), energy expenditure (accelerometry and indirect calorimetry), food reward (responses to visual food cues) and olfactory sensitivity. Recently, she has used commercially-available activity trackers to monitor and promote physical activity behavior change in breast cancer survivors. Dr. McNeil is a Certified Clinical Exercise Physiologist by the American College of Sports Medicine.
