About This Episode:

Have you ever wondered how exercise affects our appetite and energy intake? While we know that single bouts of exercise can create a short-term energy deficit, do they also influence our hunger levels? And what about long-term exercise training? Could it modify our appetite in ways that help us better control our weight?

Recent research suggests that exercise may indeed play a role in appetite regulation. Could exercise modify the subjective and homeostatic mediators of appetite in ways that enhance our feelings of fullness after a meal?

One of the most fascinating aspects of this research is the variability in responses between individuals. Why do some people experience changes in appetite and energy intake after exercise, while others don’t? Could factors like adiposity, sex, or habitual physical activity levels play a role?

In this episode, Dr. James Dorling of the University of Glasgow helps us delve into the evidence surrounding how factors like adiposity, sex, and habitual physical activity modulate our responses to exercise in terms of appetite, energy intake, and appetite-related hormone responses.

About The Guest:

Dr. James Dorling is a lecturer in Human Nutrition at the University of Glasgow. Dr. Dorling’s research is broadly focused on three areas: (1) the impact of nutrition and physical activity interventions on obesity-related endpoints and biomarkers of aging; (2) the regulators of appetite and eating behaviours; and (3) the changes in appetite and eating behaviours in response to health interventions.

During his PhD, he studied the effects of acute exercise and obesity-related single nucleotide polymorphisms on appetite and appetite-related hormones. Following this, Dr. Dorling joined Pennington Biomedical Research Center where he worked as a postdoctoral researcher. His postdoctoral research principally focussed on the influence of calorie restriction and physical activity on weight, markers of aging, and eating behaviours.
