Justin Roberts, PhD, SFHEA, FBANT is a Professor of Nutritional Physiology applied to exercise and functional health within the Cambridge Centre for Sport and Exercise Sciences at Anglia Ruskin University in Cambridge, and the Research Facilitator at CISN. He is a Fellow Member and BANT Registered Nutritionist (with the British Association for Nutrition and Lifestyle Medicine), Editor-in-Chief of the Nutrition Evidence Database (supporting an evidence-based approach for nutrition professionals), and Chair of the Nutritional Therapy Education Commission (NTEC).
With over three decades of experience in nutrition, and sport and exercise physiology, Justin has worked at various institutions, including the British Olympic Medical Centre (London), Brunel University (London, where he completed his PhD), Victoria University (Melbourne, Australia), and the University of Hertfordshire. Alongside this journey, he has worked with amateur and professional athletes across a diverse range of sports, including Senior Nutrition Advisor roles for professional and national-level teams.
Justin is the co-editor of the textbook of Integrative Sport and Exercise Nutrition with Ian Craig, published by Routledge in 2025.
Justin’s research focuses on applied nutritional physiology, exploring dietary and nutrient strategies to support exercise training and recovery, muscular adaptations (pertinent to physical development and sarcopenia) and cardio-metabolic health. His current research interests explore ‘calorie- restriction-mimetic’ and polyphenol phytonutrients on physiological mechanisms associated with fat oxidation, inflammation and cardio-metabolic health; as well as nutritional factors aligned with the ‘gut-muscle axis’, in particular probiotic and protein interventions to support muscle recovery and adaptations to exercise.
