How can food improve your performance or general life?

Your food will play a key role in your:

  • Overall health

  • Fuelling individual training sessions

  • Recovery from training or between events

  • Adaptations from training to make you bigger, faster, fitter, stronger

  • Maximise your performance during competition

Jonathan here, founder of Compleat Performance and a SENr registered performance nutritionist.

Compleat Performance has one goal, to improve you. Training and sport is highly individual to you. It may be how you keep yourself sane and handle stress. It may be about the journey whether that be fat loss, recovering from an eating disorder or finding your limits. It may be improving yourself one day at a time. It may be about competing at the highest level or winning. It may even just be for the fun of it. Whatever your reason, it is highly individual as is your nutrition.

There is no 'one size fits all' approach as we are all individual with different needs that change over time. What your body needs to fuel itself is determined by your sport, training load, ambitions/goals, lifestyle, age, gender, stress and your current physiology.

Compleat Performance has supported a wide range of athletes from recreational up to World Championship competitors & Olympians from a variety of sports including running (middle & long distance), swimming, cycling, triathlon, football and rugby.

I hope you find something to improve you on this site and feel free to reach out to discuss how to improve your nutrition and performances.
