Introducing Feed.Fuel.Perform Nutrition

Hey there, Sinead here! I am SUPER excited to be writing this blog and to be linking up with CrossFit ChalkBox on all things nutrition. 

Before we get to the interesting stuff, a whistlestop intro to me … a scientist by trade I earned my doctorate researching metabolism. After a detour into the corporate world, I returned to science and nutrition to found Feed.Fuel.Perform – working with individuals to optimise their nutrition to maximise health and performance inside and outside of the gym. 

Nutrition, does it really matter?

Eating is second nature (and something to be enjoyed!). We know we wouldn’t last long if we didn’t eat or drink. Equally, we know eating and drinking too much is bad for us. But how often do we think about what food is really for? 

Food is the energy we need to do work (move, talk, think, breathe …), and the building blocks to make and maintain our bodies (and grow muscle!).


Without appropriate foods, eaten in appropriate quantities, humans cannot reach their full potential. The ‘right’ nutrition is essential for getting the most out of your training, healthy career longevity, and functional fitness into old age.

But 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 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!

So, what can I do for you?

I offer a range of nutrition coaching services, from in depth food diary analysis and consultations through to detailed daily menu planning. Check out the services on offer at

Most importantly, I want to give you the support you need to smash your nutrition goals and feel awesome in training and in life, so hit me up with topics you’d like me to cover in future blog posts, recipes you’d like to see here and on Instagram, and any other ideas and struggles you have!
