Explore the science of gut health and the power of personalised nutrition at your next event with Tim Spector, Professor of Epidemiology at King's College London and scientific co-founder of ZOE. His research on how individual biology drives performance has reached millions through five bestselling books and two Netflix documentaries.
Tim Spector is a Professor of Epidemiology at King's College London whose research is reshaping how the world understands food, gut health, and personalised nutrition. He is the scientific co-founder of ZOE, the gut health science company behind the world's largest nutrition study.
Tim has published more than 900 research papers and ranks among the top 100 most cited scientists globally. His five books, including the Sunday Times bestsellers Spoon-Fed and Food for Life, have reached readers around the world. His Netflix appearances and Channel 4 documentary What Not to Eat have made complex science accessible to millions.
Tim's research directly challenges the one-size-fits-all approach to diet advice. Through the ZOE PREDICT programme, conducted alongside teams from Harvard, Stanford, and Oxford, he has demonstrated that individual biological responses to food vary far more than conventional guidance acknowledges. His work on the Covid Symptom Study app, used by over four million people, earned him an OBE and proved that large-scale citizen science can generate real public health impact.
Audiences leave Tim's sessions with a clearer understanding of why standard dietary guidelines often fail individuals, how gut microbiome diversity connects to long-term health outcomes, and what practical, evidence-based steps they can take to improve their own diet.

Tim Spector draws on findings from large-scale nutrition research, including the ZOE PREDICT programme conducted with Harvard, Stanford, and Oxford, to challenge standard dietary guidelines and explain how individual biological responses to food vary. He translates this evidence into practical, audience-facing guidance on gut microbiome diversity and personalised diet choices.
Prof. Tim Spector OBE speaks on nutrition science, gut microbiome diversity, personalised dietary responses, and the limitations of conventional dietary guidelines. He is Professor of Epidemiology at King's College London, scientific co-founder of ZOE, and ranks among the top 100 most cited scientists globally, with over 900 published research papers.
No. PepTalk adds no booking fee, so you pay the speaker's fee and nothing beyond it. The service, from shortlist through to contracts and event-day logistics, is included. For repeat or multi-event bookings, PepTalk can agree preferential rates with your procurement team.
