About me.

I’m Nerys Williams Giuliani — a nutrition and lifestyle coach, scientist, and mother of two. Originally from Wales, I live in Utrecht, the Netherlands since 2009, and work primarily with working mothers and women experiencing long-term fatigue or burnout that hasn’t resolved with rest, therapy, or lifestyle changes alone.

How I Work

I take a root-cause–informed, whole-person approach.

Rather than assuming food or stress management alone will fix everything, I help clients explore whether underlying biological factors — such as iron deficiency, hormonal changes, or thyroid-related issues — may be contributing to their fatigue.

I work alongside medical care, offering clarity, context, and ongoing nutrition and lifestyle support while those pieces are addressed.

My Background

I hold a PhD in Biomedical Sciences, specialising in stem cell therapy for diabetes, and previously worked in corporate biotech for many years. My scientific training shapes how I think about fatigue, recovery, and the body’s ability to adapt and repair.

Why This Work Is Personal

I’ve also been on the other side.

After years of pushing through exhaustion while balancing work and family life, I was labelled as “burnt out.” Lifestyle changes helped somewhat, but it wasn’t until an undiagnosed iron deficiency was identified that recovery became possible.

That experience changed how I see fatigue — and how I support women who sense that something important is being missed.

My Focus

I support women with long-term fatigue by offering what is often missing: time, clarity, and continuity.

I take the time to go through your full picture — your symptoms, health history, lifestyle, and everything you’ve already tried. Together, we explore possible explanations, discuss available options, and shape a clear, realistic plan.

Because when you’re very tired, doing this alone — researching, organising information, following through — can feel overwhelming. My role is to support you through that process and stay alongside you as you work towards recovery.
