Dr Marie Spreckley is a Principal Investigator, researcher and Registered Nutritionist (Public Health) at the University of Cambridge, specialising in behavioural weight management, nutrition and lived experience research. She leads AMPLIFY, a mixed-methods study examining the lived experiences, nutritional impacts and support needs of adults using next-generation incretin-based therapies for weight management, with a particular focus on equity, acceptability and real-world gaps in care. Her wider research has examined nutritional strategies for people using these treatments, gaps in nutritional guidance and support, and the implications of food insecurity for equitable obesity care.

Drawing on extensive clinical experience across NHS and private weight-management services, Dr Spreckley’s work sits at the intersection of behavioural science, nutrition, clinical care and emerging obesity treatments. Her research examines how psychological processes, dietary support and health-system design shape sustainability, well-being and equity in obesity care, with a particular emphasis on redefining success beyond weight alone.
