no fads, just straightforward, diet-free advice


Hi, I’m Abi.

I’m on a mission to break down misinformation around food, remove the barriers and help restore healthy relationships between all foods and all bodies. I practice weight-inclusive, non-diet nutrition – no fad-diets, meal plans or strict rules. We work together to find a way of eating that suits you.

I am an evidence-based nutritionist – all of the advice I follow and share has a solid basis in high quality research. I focus on weight-inclusive health and wellbeing and advocate for Heath At Every Size (HAES®) and Intuitive Eating.

Nutrition (ok, food) has always been my favourite topic, but it hasn’t always been my job. I spent 15 years working in fashion between degrees, and whilst I’ve swapped fashion magazines for research journals it was the best decision I ever made. That’s not to say I didn’t learn anything during my time in fashion: I developed vital skills in communication, motivation, coaching, team building and strategy which really come in handy when working with people and running your own business. From a personal perspective I understand that figuring out what to eat isn’t always easy – I have had food allergies my entire life and have always had to pay attention to what I eat but without letting it take over my entire life.

So, why me? As a Registered Nutritionist with the Association for Nutrition, I have been certified as having the depth of knowledge necessary to be part of their team (find me here, on the UK Register of Nutritionists, under Abigail Sleven).

I have a Master’s degree (MSc) in Human Nutrition (with distinction) and a Bachelor’s degree (BSc) in Biological Sciences as well as training in Intuitive Eating. This formal education shows a detailed understanding of the body and the complex interactions between food, metabolism and hormones.

So, if you need help to break up with diet culture, support with making changes or just want to make sure you are on the right track I will work alongside you to inform, encourage and enable you to reach your goals. You can book in for a discovery call, or drop me a message on the contact page to find out more.


Consultations are available virtually, via Skype, or in-person at my clinic in Hove. Please check availability when booking.
