Dr Lewis Mattin
I have an undergraduate degree in Exercise Nutrition and a MRes in Sports Nutrition, both from Nottingham Trent University (NTU) where I worked closely with Dr Lewis James. I was a postgraduate teaching assistant at Manchester Metropolitan University (MMU) where I also completed a PhD. During this time, I studied how exercise effect’s gastrointestinal function, appetite, and metabolic regulation with the guidance from Dr Gethin Evans & Dr Adora Yau. In 2021 I joined the University of East Anglia as a Lecturer in Physiology before tacking 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. Furthermore, an active member of The Physiological Society, in which I am the representative at the University of Westminster and a full member for the Society for Endocrinology in which I am a member of the public engagement committer.
In addition to these core interests, I am actively engaged in research aiming to recognise how the human microbiome trigger’s the gut-brain axis leading to changes in appetite and gut permeability; the relationship between diet and exercise within ethnic minorities (DoS: Manpreet Mujral). Furthermore, research that identify mechanism of ageing and novel active components of macro and micro-nutrients using a range of population; healthy, over-weight, athletic, sport, and exercise nutrition settings predominantly using Human Volunteers.
This research aims to enhance knowledge related to metabolic regulation, time of day feeding, and weight-management. With a special 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).
