Dr Justin Roberts

Justin is an Associate Professor in Health and Exercise Nutrition with a focus on applied and health-based nutrition. His interests encompass a wide range of areas including how both dietary and nutrient interventions can impact on adaptations to exercise, both in terms of physiological and metabolic health, as well as enhancing recovery.

Background

Justin joined the Sport and Exercise Science team at ARU in 2014, and is an Associate Professor and researcher with our Cambridge Centre for Sport and Exercise Sciences. He is an accredited Sport and Exercise Physiologist and Chartered Scientist with the British Association of Sport and Exercise Sciences (BASES) and current BASES laboratory director. He is also a Registered Nutritional Therapist with the British Association for Nutrition and Lifestyle Medicine (BANT) and the Complementary and Natural Healthcare Council (CNHC).

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.

Justin 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.

Research interests

• Effectiveness of polyphenols on fat oxidation, health biomarkers and exercise performance
• Use of intermittent fasting and ketogenic diets on fat oxidation and exercise adherence
• Assessing the benefit of high protein diets in trained athletes on recovery, satiety and adaptive gains
• Influence of combined dietary and supplementation strategies on exercise performance and post exercise recovery
• Nutritional strategies to minimise gastrointestinal issues associated with aerobic exercise
• ‘Nutritional psychology’ – the use of mindfulness-based strategies to influence acute food choices and behaviours.
