About Little O Nutrition

Our mission

Little O Nutrition is committed to providing an evidence-based and compassionate approach to nutrition and lifestyle advice. We aim to help you to develop sustainable and healthy food habits in a judgement free environment. 

Our nutritionist

Our nutritionist, Oonagh Trehin, is a registered associate nutritionist (anutr) with a BSc nutrition and MSc public health. Oonagh is passionate about nutrition and health and sharing the Little O message with the world. 

Our ethos

  • All foods have a place in our diets; but diets don’t!

  • Everyone deserves equal care and advice regardless of their appearance, size or any other factor.

  • Quality advice must be tailored to each person- no regimental plans, miracle pills or fix all recipes here!

Lots of love,

Little O (Oonagh)
