My 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 a healthy condition to an unhealthy 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 serval societies and grant funding interests.
I research health, sport, and exercise nutrition predominantly using human volunteers to enhance knowledge related to metabolic regulation, time of day feeding, and appetite control. With a special interest in endocrinology related to gastrointestinal hormones.
