Introduction
Effective athlete support requires more than delivering technically correct nutrition advice. It depends on understanding the athlete’s wider environment, anticipating the pressures that disrupt good intentions, and building flexible routines that remain useful across training, competition, travel and everyday life.
This episode explores how practitioners can move beyond rigid prescriptions, use “good, better, best” options, measure meaningful progress, and create environments in which athletes can communicate openly about difficulties. It also examines identity, transitions out of sport, and why sustainable support should develop an athlete’s autonomy rather than dependence on the practitioner.
To discuss all this is Gemma McGuinness, registered performance nutritionist, former professional footballer and co-founder of Verus Performance.

Study Notes
Useful Terminology
- Athlete-centred support: Support organised around the athlete’s goals, context, preferences, constraints and wider wellbeing, rather than around the practitioner’s discipline alone.
- Performance system: The interacting set of behaviours, skills, relationships and environmental conditions that shape preparation and performance. Nutrition is one component within this system.
- Flexible standard: A behaviour or routine linked to a meaningful outcome that can be scaled to the athlete’s current circumstances without losing its core purpose.
- Minimum viable standard: The smallest version of a useful behaviour that remains realistic when time, energy or circumstances are constrained. In the episode, this is represented by the ‘good’ tier in a good-better-best framework.
- Implementation intention: A pre-decided if-then response that links a foreseeable cue or obstacle with a specific action, such as: ‘If travel delays my planned meal, then I will use the snack packed in my bag.’
- Process measure: A measure of a behaviour or capability that is relatively close to the intervention, such as meal preparation, pre-training fuelling or cooking confidence.
- Proximal outcome: An outcome likely to respond more directly to the intervention than the final competition result, such as perceived energy during a specific training session.
- Athletic identity: The degree to which a person identifies with the athlete role. A strong athletic identity can provide meaning and commitment, but a narrow identity may make injury or retirement more difficult.
- Disordered eating: Problematic eating attitudes or behaviours that may impair health or functioning but do not necessarily meet diagnostic criteria for an eating disorder.
- Psychological safety: A shared perception that people can ask questions, acknowledge problems and raise concerns without interpersonal punishment, humiliation or inappropriate threat to their role.
Nutrition as an Investment Beyond the Next Performance
A narrow performance-only frame can make nutrition feel relevant only around training, competition or the in-season period. McGuinness argues for a broader frame in which nutrition also builds durable skills and supports health, wellbeing and life outside sport.
- Performance remains a legitimate reason to improve nutrition, but it should not be the only one.
- Athletes may initially engage because they want more energy, better preparation or a body-composition change.
- That motivation can be used to develop capabilities that remain valuable during injury, the off-season and after retirement.
- Examples include planning meals, cooking, adapting food choices, noticing how routines affect wellbeing, and
