What it’s all about

I am a biologist. As a student I focussed on cell biology and human genetics. This led me to a keen interest in metabolism, which in turn led me to a PhD studying the regulation of cell growth – specifically, the things cells need to add mass and volume and to function.

Feed.Fuel.Perform was born out of the belief that nutrition is at the heart of optimal performance in training and in life. Without appropriate foods eaten in appropriate quantities no human can reach their full potential. Fueling effectively is important for everyone from the elite athlete to the weekend warrior.

Feed.Fuel.Perform is also born out of the recognition that no one size fits all in nutrition. Indeed, there is no one size fits one. Every body is different, and the needs of every body changes over time. What your body needs now is not just driven by your training and lifestyle, it is also dependent on your age, gender, genetic background, stress and physiological state. And it is of course influenced by your goals – be they aesthetic, performance or otherwise!

Centuries of science has led us to a point where there is much we do understand about the human body, nutrition and performance. However, there is also so much that remains unclear, unknown and yet to be discovered. An understanding of both what is known and what is unknown should be accessible to all, yet there remains so much misleading information and misinformation in the public domain. The aim of this site is to discuss the evidence for and against a whole host of nutritional principles, and how this might relate to the food choices you make each day – from macronutrients to micronutrients, and all in between. On this site I also share a variety of recipes designed to support one or more aspects of a healthy body or training goal, with variations to consider depending on who you are, what you do, and your goals.

I hope you enjoy the site, and please do get in touch – I’d love to hear your thoughts.
