How can you fuel your body to maximise performance?

To answer this we must consider the role of nutrition in:

  • Health

  • Fuelling individual training session

  • Recovering from training

  • Adapting to training to make us fitter, faster, stronger

​Hey there,

Sinead here - owner of Feed.Fuel.Perform and SENr registered performance nutritionist.


I established Feed.Fuel.Perform in 2018 to help recreational and professional athletes make better use of nutrition to optimise their training, recovery and performance. We do this through a combination of nutrition coaching and education, working with athletes across a range of disciplines, including MMA, Jiu Jitsu, Boxing, Olympic weightlifting, CrossFit, Strongman and endurance sports

Central to Feed.Fuel.Perform's philosophy is the recognition that no one size fits all in nutrition. Indeed, no one size fits one. Every body is different, and the needs of every body changes over time. What the body needs now is driven by sport, training load and lifestyle, as well as age, gender, genetic background, stress and physiological state. And, of course, by an individual's goals – be they aesthetic, performance or otherwise! 

I hope you enjoy the resources on this site. And please do get in touch to discuss your nutrition.

A bit more about me, if you are interested ...


One of my favourite quotes in this field is Jack LaLannes statement that “Exercise is King. Nutrition is Queen. Together you have a Kingdom”! In other words, to reach your full physical potential you need both working together.


My doctoral research focussed on understanding metabolism at the level of the cells of our body. I geek out on anything and everything related to the science behind the nutrition for sports and performance, and the translation of that science into practical strategies to fuel athletes in training, life and competition.

My own training is a mix of strength, conditioning and CrossFit. What I lack in talent and skill, I make up for in enthusiasm!! I also love a run to clear the head, a hike to get out in the countryside, and cycle ... preferably mountain biking. 

Don't call me a one trick pony, but my spare time closely mirrors my career passions! I love to cook and eat, and use this as an opportunity to develop recipes that you might see appearing on this website or in meal plans produced for clients. And I love sports ... most commonly found watching Formula 1, boxing, MMA or CrossFit.
