About me

I'm Jessica Fonteneau, a Registered Nutritional Therapy Practitioner specialising in skin health, food allergies/intolerances, histamine and MCAS . With a deep understanding of nutritional imbalances, I work closely with clients, assessing how these factors contribute to their health concerns. 

Having personally experienced the challenges of skin and gut issues since childhood, my mission is to empower others facing similar struggles. I've supported numerous clients in transforming their diets to manage flares and find relief.

Through personalised assessments and, if needed, functional testing such as nutrigenomics and stool analysis, I tailor recommendations to each person's unique needs. My goal is to provide not just relief but a pathway to understanding and managing these debilitating conditions. 

Training, qualifications & experience

I have been working in clinic with individuals, groups and offering self-guided programmes since 2014. I have an MSc in Transdisciplinary Practice and my dissertation was entitled "‘Examine how nutrition maybe used as a complementary tool for chronic Atopic Eczema/Dermatitis (AD) Support"

I also have a DipIoN, qualifying me to be a Registered Nutritional Therapist, CNHC and Nutritionist mBANT.

Nutrition topics

Information about health conditions (*)

Nutritional therapy can help enhance the well-being of individuals diagnosed with serious medical conditions, but should not take the place of medical treatment and advice. If you have been diagnosed with - or suspect you may have - any of these conditions, please speak to your doctor before starting nutritional therapy or making any major changes to your diet or lifestyle.

Additional information

Each person I assist has their own unique triggers and ideal nutritional needs—there's no 'one-size-fits-all' solution. My aim is to guide you in discovering what truly works best for you, empowering you to reclaim control and find relief. This isn't a quick-fix diet; it's a sustainable, long-term lifestyle change that leaves you feeling so fantastic, you'll never want to go back.

Every program is personalised, considering your health journey, goals, dietary preferences, and lifestyle. Throughout our journey together, I'll offer unwavering support, providing not only nutritional guidance but also recommendations for managing stress, improving sleep, and making lasting habit changes. Together, we'll explore why popular diets might work for some but not for you, ensuring your approach aligns perfectly with your needs and aspirations.

My aim is to guide you to change your nutrition for the long-term. My recommendations not only suit your health and wellbeing, but also fit into your lifestyle so that they are easy to implement and maintain.  Your current habits have led you to this point and it is I offer health coaching for habit change as part of my one-to-one consultations.
