Jeukendrup has published extensively in sport nutrition. He is a fellow of the American College of Sports Medicine and the European College of Sport Science. In his leisure time, he enjoys running, cycling, and competing in triathlons. To date, he has completed 21 Ironman races, including 6 Ironman Hawaii competitions.

Michael Gleeson, PhD, is a professor emeritus of exercise biochemistry in the School of Sport, Exercise, and Health Sciences at Loughborough University in Leicestershire, United Kingdom. Gleeson is considered a world authority on exercise biochemistry, immunology, and nutrition, and he has worked with numerous world-class athletes and professional football (soccer) clubs. He has taught sport nutrition at the university level. He has written several books, 30 book chapters, and over 250 scientific articles in scientific and medical journals, and he has coauthored textbooks on exercise metabolism, exercise immunology, and sport nutrition.

Gleeson has been both president and vice president of the International Society of Exercise and Immunology. He is a fellow of the European College of Sport Science and the British Association of Sport and Exercise Sciences. He is also a member of the American College of Sports Medicine and the Physiological Society.

Following his retirement in 2016, he turned his attention to how ordinary people can achieve optimal health and live healthier for longer. In 2020 he released a series of healthy lifestyle guidebooks about the benefits of being active and eating and sleeping well, advice about natural means to reverse type 2 diabetes without medication, and how to use multiple diets for effective and safe weight loss. Based on his extensive experience and love of football, and following his work as a coauthor of the UEFA expert group statement on nutrition in elite football, he authored a 2022 book on nutrition for top performance in football. He enjoys playing tennis, hill walking, and watching football and films.
