Dr Lewis Mattin
I have an undergraduate degree in Exercise Nutrition and an MRes in Sports Nutrition from Nottingham Trent University (NTU), where I worked closely with Dr Lewis James during the BSc program and Prof Craig Sale & Prof Kirsty Elliott-Sale during the MRes program before progressing to a Postgraduate Teaching Assistant at Manchester Metropolitan University (MMU), where I also completed a PhD. During this time, I studied how exercise affects gastrointestinal function, appetite, and metabolic regulation with guidance from Dr Gethin Evans & Dr Adora Yau. In 2021, I joined the University of East Anglia (UEA) as a Lecturer in Physiology before taking up my current position in 2023 at the University of Westminster as a Lecturer in Human Physiology.
I am a Fellow of the Higher Education Academy, an active member of The Physiological Society as the Early Career Researcher EDI Rep, and the University of Westminster representative, as well as The Society for Endocrinology public engagement committee member.
In addition to these core interests, I am actively engaged in research to recognise how the human microbiome triggers the gut-brain axis, leading to changes in appetite and gut permeability, and the relationship between diet and exercise within ethnic minorities (DoS: Manpreet Mujral). Furthermore, research which identifies the mechanisms of ageing and novel active components of macro and micro-nutrients using a range of populations: healthy, overweight, athletic, sport, and exercise nutrition settings predominantly using Human Volunteers.
This research aims to enhance knowledge of metabolic regulation, time of day feeding, and weight management, with a particular interest in endocrinology related to gastrointestinal hormones.

Dr Mattin is an active early career translational scientist with experience in exercise, health, and extreme environmental physiology/ nutrition. His interests spans from elite performance from being an international Swimmer to a range of physical activity topics and further research interests:
His research employs randomised controlled trials using human volunteers to study the effects of nutrition and exercise on the gut-brain axis and metabolic regulation. The primary focus is to comprehend weight management within a recreational fit population to prevent long-term fat accumulation after exercise. Secondly, recognise how substrate utilisation, appetite and gastrointestinal response change as humans move from an unhealthy condition to a healthy state.
Although, this research has a strong exercise prescription and nutritional origin, it also has a compelling endocrinology focus related to changes in gut hormones (Ghrelin, GLP-1, and PYY), after exercise, nutrient ingestion or within a fasted state. This research area is multidisciplinary and sits on the edge of serial societies and grant funding interests (BBSRC and MRC).
