Biography
Dr. Lorna Doyle is a lecturer in Nutrition in the Dept. of Health Sport and Exercise Science at Waterford Institute of Technology. Dr. Doyle completed her BSc Ed at University of Limerick and continued to further her education by completing her MSc and PhD in the area of Clinical Nutrition at UCC. She is a registered nutritionist with nutrition specialism in Sport and Exercise. She has been a lecturer at WIT for over 11 years and supervised several research students investigating aspects relating to: protein supplementation and bone health, low carbohydrate diets and its effect on weight loss, bone health and cardiovascular effects. She is also investigating the effect of low carbohydrate diets on health and sports performance with athletes. Dr. Doyle is interested in any type of research which affects the health of individuals and/or their performance in sport.

Dr. Doyle is currently investigating the effects of a low carbohydrate versus high carbohydrate diet on endurance athlete performance and health. Aspects measured in this research include time trial performance, power output, fuel utilization, bone density, lean body mass, bone formation and resorption, blood cholesterol and inflammatory markers. Her postgraduate student is currently on an internship at Ohio State University under the supervision of the esteemed Prof. Jeff Volek and his research team. Dr. Doyle is also involved in supervising research examining energy balance in athletes.
Dr. Doyle has been internal examiner for several PhD viva's. She is a member of the Nutrition Research Center at WIT. She is also a member of the Nutrition Society.
