Dr Emily Leeming started out cooking as a private chef on superyachts before the science bug took hold. That path, from professional kitchen to research lab, shapes her work today and her guiding belief that healthy eating should be simple and taste good.
Emily is a registered dietitian and research scientist at King's College London. She holds a BSc in Nutrition, an MSc in Dietetics, and a PhD in nutrition and the gut microbiome. Her research includes the EAT-FIBRE study, part of Cancer Grand Challenges Team PROSPECT, a Harvard University-led global research programme.
Emily’s book Genius Gut was published in 2024, followed by Fibre Power in 2026. She writes a weekly newsletter, Second Brain, on gut health and nutrition and contributes regularly to the BBC, The Sunday Times, The Telegraph, and The Guardian. She is also a columnist for The Daily Mail. Her media work spans television and radio, keynote stages, a TEDx talk, and high-profile podcast appearances, making her one of the most visible science communicators working in nutrition today.
Emily's dual background in professional cooking and clinical research gives her something rare: the ability to translate complex gut health science into food choices people will actually make. Her work connects laboratory findings to everyday eating, removing the gap between what the evidence says and what ends up on our plates.
Audiences leave her sessions with a clear understanding of how gut health affects energy, mood, and long-term wellbeing, practical ways to improve their diet without having to overhaul it entirely, and the confidence that eating well really can be simple.
Book Emily when you need complex science made genuinely accessible, and a speaker who leaves audiences not just informed, but ready to act.
Dr Emily Leeming's background as a research scientist at King's College London and as a trained chef gives her the ability to close the gap between clinical evidence and practical eating behaviour. Her work on the EAT-FIBRE study and her role in the Harvard-led PROSPECT programme mean the science she brings to the stage is genuinely cutting-edge.

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.
Share your event date, audience, format, objectives and budget, and PepTalk sends a hand-picked shortlist within 24 hours. Each suggestion comes with a profile, a fee and a recommendation on the strongest fit. Once you choose, PepTalk handles contracts, travel and logistics through to event day.
The typical fee range is the speaker's standard in-person fee in their home market, shown in their local currency. It moves with format, location, date and session length: virtual sessions and shorter slots usually cost less, while international travel and peak dates cost more. Send your brief to PepTalk and the team will confirm the exact fee in your currency.
Not all of them, and it makes no difference to your booking. PepTalk's network of 15,000+ speakers covers talent the team works with directly alongside speakers represented by agents and agencies worldwide. PepTalk approaches the speaker, negotiates the fee and handles contracting either way.
Three to six months ahead is comfortable for most events, and 12 months is better for large conferences, peak-season dates or one specific in-demand speaker. Shorter timelines are workable, and PepTalk regularly fills last-minute and replacement bookings within days. Availability is the constraint, so get in touch as soon as you have a date.
