We Do Science

Should women train and eat differently from men? In this episode of We Do Science, I’m joined by Dr Lauren Colenso-Semple to explore female physiology, resistance training and how we translate research into practical recommendations.

Drawing on her experience as both a coach and a researcher, Lauren discusses her work examining muscle protein synthesis across menstrual cycle phases. We explore the evidence behind cycle syncing, the importance of measuring hormones accurately, and why findings from animal studies don’t automatically translate into training advice for humans.

We also discuss hormonal contraceptives, energy availability, injury-risk claims and resistance training across the menopause transition. Throughout, we distinguish between blanket recommendations for women and individual adjustments that account for symptoms, preferences, training goals and lived experience.

For nutrition practitioners, coaches, athletes and anyone interested in women’s training, this conversation examines which claims are supported by research, where uncertainty remains, and how to personalise an approach without adding unnecessary complexity.

What does it take to deliver performance nutrition in the NFL? In this episode of We Do Science, I’m joined by Dr Matt Frakes of the New York Giants to explore the realities of supporting elite athletes and turning nutrition research into everyday practice.

Matt shares his journey from college football player and clinical dietitian to working in collegiate sport and the NFL. We discuss why qualifications alone don’t earn an athlete’s trust, how to build relationships with players and their support networks, and what individualised nutrition looks like within a team environment.

We also explore Matt’s doctoral research into nutrition and concussion recovery, his experience supporting an athlete during Ramadan, and the practical challenges of feeding players both inside and outside the training facility. Along the way, we discuss supplements, commercial testing and the demands of supporting recovery across a long, physically demanding season.

For sports nutrition practitioners, coaches and students, this conversation offers an honest look at the communication, collaboration and judgement involved in working at the highest level—and the lessons Matt would share with someone starting out.

What happens to your muscles when you exercise in a calorie deficit? In this episode of We Do Science, I’m joined by Dr José Areta, Associate Professor in Exercise Metabolism and Nutrition at Liverpool John Moores University, to explore how muscle responds when energy intake is reduced—and why muscle size is only part of the picture.

José takes us through his research examining five days of low energy availability alongside aerobic exercise in men. Looking beyond body weight and lean mass, his team tracked changes in individual muscle proteins to understand how the muscle was adapting.

We discuss what they found, including changes in proteins involved in energy production, and explore the distinction between muscle quantity and quality. We also consider how the body prioritises energy, the role of protein intake, and the relevance of these findings to athletes managing their body composition.

Throughout, we address the study’s limitations and why short-term changes shouldn’t be taken as evidence that prolonged energy restriction improves performance. For practitioners, coaches, athletes and students, this conversation offers a closer look at the relationship between nutrition, exercise and muscle adaptation.

Is more protein always better? In this episode of We Do Science, I’m joined by Professor Nick Burd to explore protein nutrition, muscle adaptation and why the amount of protein we eat is only part of the story.

Returning to the podcast after six years, Nick shares insights from his research at the University of Illinois into protein metabolism and the food matrix: how a food’s structure and surrounding nutrients influence the way our bodies respond to it. From eggs and salmon to whey and casein, we examine what we can learn from studying whole foods alongside isolated proteins and supplements.

We discuss the difference between maximal and optimal protein intake, why muscle protein synthesis shouldn’t automatically be equated with muscle growth, and how protein strategies may differ between strength and endurance athletes. We also explore anabolic resistance, muscle quality and the questions researchers are still working to answer.

Whether you’re a sports nutrition practitioner, coach, athlete or student, this conversation offers a closer look at how to interpret protein research and apply it in practice, with a reminder of the central role of consistent exercise in supporting muscle adaptation.

On this episode of We Do Science, Dr Laurent Bannock welcomes back Dr Dana Lis, registered dietitian and performance nutrition practitioner, alongside chef and nutritionist Nicki Strobel, to discuss their paper Plate to Performance: Culinary Nutrition Support for Professional Road Cycling, part of the UCI Sports Nutrition Project.

Drawing on years of experience in elite cycling, Dana and Nicki explain how the culinary nutrition team of nutritionists, chefs and soigneurs turns evidence into food riders will actually eat across Grand Tours, Classics and training camps. The conversation covers the chef–nutritionist relationship, on-bike fuelling, menu planning around stage demands, and how power meter data, doubly labelled water and continuous glucose monitors inform daily decisions.

Laurent, Dana and Nicki also discuss educating riders in a decentralised sport, building buy-in across the team, planning for illness, crashes and kitchens without power, and where the journey from science to plate most often breaks down. With lessons that apply well beyond cycling, this episode offers sports nutritionists, chefs, coaches, students and athletes a practical look at how performance nutrition is delivered in the real world.

We Do Science with Dr Laurent Bannock returns, now with video! In this first episode back, Laurent welcomes Professor Michael Gleeson, Emeritus Professor of Exercise Biochemistry at Loughborough University, to explore the four Ps of performance nutrition: personalise, periodise, pre-fuel and prepare.

Drawing on his research and experience in sports nutrition, Michael explains how this framework can help practitioners turn scientific evidence into practical decisions for their athletes. The conversation covers carbohydrate fuelling, hydration, gut training and supplements, alongside the importance of adapting nutrition strategies to training demands, individual preferences and the realities of competition.

Laurent and Michael also discuss the role of wearables and testing in personalised nutrition, the challenges of supplement marketing, and why more information doesn’t always lead to better decisions. With examples from football and endurance sport, this episode offers sports nutritionists, coaches, students and athletes a practical look at choosing, applying and evaluating nutrition strategies.
