315: The Under-fueling Problem in Professional Sport with Dr Nessan Costello

Science for Sport — Mon, 13 Apr 2026 06:00:00 +0100

Sports nutrition in elite football is often misunderstood, even by the players doing it for a living. In this episode, Richard Graves sits down with Dr. Nessan Costello, 1st Team Sports Nutritionist at Al-Ahli in the Saudi Arabia Pro League, to cut through the noise and get practical about what performance nutrition actually looks like at the highest level.
Nessan has worked across the Premier League with clubs including Chelsea, Newcastle United and Leeds United, and brings a rare combination of academic rigour and real-world experience to the conversation. From fuelling strategies across a congested fixture schedule to navigating Ramadan with Muslim players, and from debunking carbohydrate myths to calling out the damage done by overly controlling nutrition environments, this is a frank and refreshingly honest look at what it takes to keep elite footballers performing at their best, week in, week out.
Whether you're a practitioner working at the sharp end of elite sport, a coach trying to get more out of your athletes, or simply someone who wants to understand the science behind peak performance, there is plenty here for you.

In This Episode You Will Learn

Why the majority of elite footballers are chronically underfuelled — and why that matters more than their body fat percentage
The real science behind carbohydrate loading: why you should start 24 hours before kick-off, not the night before, and what foods actually work
How to structure post-match nutrition across a 72-hour recovery window, including the specific gram-per-kilogram targets Nessan uses with his players
Why ultra-lean body composition as a performance goal is actively harming players, and how disordered eating behaviours are more common in elite football than most environments will admit
How Nessan adapted his approach during Ramadan — including training sessions at 10pm and cup semi-finals kicking off at 1:30am
The practical hydration framework he uses: why 500ml of fluid with every meal beats carrying a big bottle around all day
How nutrition changes across a full season, from pre-season heat acclimatisation through to the demands of a congested run-in
Why supplements are largely irrelevant until you've nailed sleep, three meals a day, two snacks and consistent hydration
What working in the Saudi Pro League has taught him about personalised nutrition across diverse nationalities and food cultures
His advice for coaches and practitioners working without a dedicated nutritionist — and when it becomes worth bringing one in

310: Why Female Physiology Still Needs Greater Attention in Sport with Dr Candice Macmillan

Why Female Physiology Still Needs Greater Attention in Sport with Dr Candice Macmillan

This week on the Science for Sport Podcast, host Richard Graves welcomes Dr Candice Macmillan, lecturer at the University of Pretoria, sports physiotherapist, and course author of “Contraceptives and the Female Athlete” on the Science for Sport platform.

As women’s sport continues to grow professionally around the world, understanding the unique physiological considerations of female athletes has never been more important. Yet many practitioners still feel underprepared when supporting athletes through topics such as the menstrual cycle, hormonal contraceptives, and their potential implications for performance, wellbeing, and decision-making.

Drawing on her background as a sports physiotherapist, researcher, and academic, Dr Macmillan explores how practitioners can better support female athletes through education, communication, and evidence-based decision making.

The conversation covers the complexity of hormonal contraceptives, how different types influence physiology and behaviour, and why awareness of factors such as testosterone suppression and symptom tracking may be crucial for athletes and support staff alike.

Perhaps most importantly, Dr Macmillan explains why empowering athletes to ask the right questions about their own health may be one of the most powerful tools practitioners can provide.

This episode offers valuable insights for sports scientists, strength and conditioning coaches, physiotherapists, and performance staff working across elite sport — while also opening up a conversation that continues to shape the future of female athlete support systems.

In This Episode You Will Learn

Why female athlete health remains one of the most misunderstood areas in elite sport
The difference between hormonal and non-hormonal contraceptives
Why the contraceptive pill is not a single solution and varies widely in composition
How hormonal contraceptives can influence testosterone levels and athlete behaviour
Why symptoms may impact performance more than hormone levels themselves
The importance of tracking menstrual symptoms for informed medical decisions
Why practitioners must help athletes learn the language to describe how they feel
The role communication plays between athletes, coaches and medical staff
How policy and education are shaping the future of female athlete support in sport

About Dr Candice Macmillan
Dr Candice Macmillan is a lecturer at the University of Pretoria, a qualified sports physiotherapist, and holds a PhD in Sports Physiotherapy.

Her work focuses on female athlete health, injury prevention, and performance, with a particular interest in how physiological factors influence training, recovery, and long-term athlete wellbeing. Through her academic and applied work, she aims to bridge the gap between research and real-world practice for practitioners working in sport.

Dr Macmillan is also the author of the “Contraceptives and the Female Athlete” course available on the Science for Sport platform, where she helps practitioners better understand the complexities of hormonal contraception and its potential implications for female athlete performance and health.

Her research and teaching continue to contribute to a growing body of work aimed at improving education, awareness, and practical support for female athletes across sport.
