GLP-1 Nutrition & Weight-Management Medicines

Overview
Curriculum
Instructor

GLP-1 weight-loss medications, including GLP-1 receptor agonists and dual GIP/GLP-1 medicines, have transformed obesity treatment. However, their effects on appetite and food intake raise important questions about nutritional adequacy, body composition and the support people need during treatment. Although practical nutrition advice is expanding rapidly, the direct evidence underpinning many recommendations remains limited and uneven.

This webinar will examine what is currently known about dietary intake, lean tissue, gastrointestinal symptoms and access to nutritional support among people using incretin-based weight-management medicines. It will consider practical priorities, including maintaining a nutrient-dense diet despite reduced intake, adequate protein alongside resistance exercise, fibre and fluid intake, symptom management, and appropriate assessment and monitoring.

The session will distinguish findings supported directly by studies of incretin therapies from recommendations based on expert consensus or extrapolated from wider weight-management and bariatric care. It will also address inequalities in access to nutritious food and professional support.

By setting current guidance alongside the limitations of the evidence base, the webinar will help nutrition professionals provide balanced, person-centred advice while recognising where further research is urgently needed.

Join Marie to:

Examine the current evidence on food intake, nutritional adequacy and body composition during incretin therapy.
Translate the evidence into practical, person-centred nutritional priorities and monitoring considerations.
Identify where current advice is based on direct evidence, expert consensus or extrapolation, and where important gaps remain.

Dr Marie Spreckley

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.
