ABOUT JUSTIN ROBERTS, PHD
Justin is a Principal Lecturer in Sport and Exercise Sciences at Anglia Ruskin University in Cambridge where he specialises in applied nutrition, with a central aim of exploring dietary and nutrient/supplementation strategies to support exercise training and recovery, cardio-metabolic health and sports performance. His current research interests involve the use of ‘calorie restriction mimetic’ nutrients on physiological mechanisms associated with fat oxidation and weight management.
With over 20 years’ experience in sport and exercise physiology and nutrition, Justin has worked at various institutions including the British Olympic Medical Centre (London), Brunel University (where he completed his PhD), Victoria University (Melbourne) and the University of Hertfordshire.
