Katie Duncalf, founder of Haraya Health
The Founder

Katie Duncalf — Built this because she lived it.

I have been in high-demand, high-stakes roles my entire career. And for years, I chose my career over my health — not because I did not care, but because I did not believe I could have both. I built Haraya Health the moment I realised I was wrong.

About Katie.

"I had become exceptionally good at performing wellbeing — rather than actually experiencing it."

Originally from New York, now living in London.

I have spent over a decade working across healthcare consulting, digital therapeutics, health tech, and life sciences — building my career in high-performance environments where everyone is solving big problems, moving quickly, and running on adrenaline.

It started during my healthcare consulting years at KPMG: late nights, all-nighters, eating whatever was available at 11pm, constantly running on adrenaline. That was where the fatigue began. The unexplained weight gain. The feeling that my body was somehow struggling to keep up with the pace I expected from it.

Outside of work, I love historical fiction novels (slightly nerdy, unapologetically so), cooking for people as a form of affection, and despite now working in wellness, I still struggle to sit alone with my thoughts for longer than five minutes without mentally planning my next idea, project, or life pivot.

A new city. The same pattern.

I moved to London for my MSc and entered the health tech world — exciting, fast-paced, exactly where I wanted to be professionally. I became Chief of Staff at one of the world's leading digital therapeutics companies, travelling constantly across Europe while quietly becoming more anxious, more exhausted, and more disconnected from my own wellbeing.

After that, I joined a digital health company focused on chronic disease management as Chief of Staff, where I helped lead the business through an acquisition alongside the founders. The stress was immense. I was missing periods. Struggling with IBS flare-ups. Dealing with chronic fatigue, anxiety, poor sleep, hormonal issues, back pain — while still performing at a very high level professionally.

Because that is what ambitious women do. We cope. Exceptionally well, actually.

The youngest. The only woman.

Following the acquisition, I joined the acquiring company — a leading European healthcare and life sciences organisation — where I became the youngest person on the senior leadership team and the only woman on the technology leadership team.

I was incredibly proud of that. I had worked hard for it. And yet underneath it all, my body was very clearly telling me something had to change.

I remember sitting in senior leadership events trying to maintain complete composure while my IBS was flaring so badly I had to keep slipping out of the room. Bringing my own food to events because explaining my health issues felt more uncomfortable than quietly managing them alone. Looking polished, capable, high-functioning — while feeling completely disconnected from my own wellbeing behind the scenes.

The decision.

We are surrounded by health advice, yet very few of us are actually taught how to be well. On one side, influencer wellness culture. On the other, a healthcare system designed around disease management — stepping in once symptoms become severe enough, once a diagnosis exists, once intervention is required.

And somewhere in the middle sits the reality most women experience: very little meaningful support to help them understand their bodies, prevent illness, build sustainable habits, or learn what wellbeing actually looks like for women living high-performance lives. That is the HARAYA gap. I left to fill it.

What Haraya means.

I am Filipina, and Haraya is a Tagalog word meaning vision — imagination, the mind's eye. More specifically, it speaks to envisioning a state not yet obtained — being able to imagine a different version of your life before you are fully living it yet.

HARAYA exists for the woman who knows she is capable of extraordinary things — and is finally ready to believe she deserves extraordinary health alongside them. Because ambition and wellbeing were never meant to exist in opposition.

Integrative Health Coaching.

"Healthcare responds to illness. Integrative health coaching was built to get there before it does."

A whole-person approach that starts with you — your history, your biology, your life — not a generic prescription.

Integrative health coaching recognises that what truly nourishes us extends well beyond what is on our plate. The quality of our relationships, our career fulfilment, our sense of purpose, our physical environment, and our emotional wellbeing are all forms of nourishment — and when any of these are depleted, our physical health pays the price.

At its core, integrative nutrition is built on one foundational principle: bio-individuality. No single diet, lifestyle, or health protocol works for everyone. What energises one person depletes another. A truly integrative approach starts with you — not a protocol.


What makes it different

Functional lens

Rather than asking "what condition do you have?", we ask "why is your body communicating this way, and what does it need?" — drawing on functional medicine principles and your whole health timeline.

Transformation over information

You already know you should sleep more and reduce stress. The gap is not knowledge — it is implementation. Coaching creates the conditions for lasting change, not temporary fixes.

Root cause focus

Gut health affects mood. Hormones affect cognition. Stress affects digestion. We work across these systems together — not in silos. Symptoms are signposts, not the destination.

Client-led

You hold the answers. A coach's role is to hold space, ask the right questions, and help you cut through the noise to find what is genuinely right for your body and your life.

"Sometimes the issue is not that you are incapable of coping. It is that your body has been compensating for too long."

What it is not

Integrative nutrition health coaching is not a replacement for medical care. Coaches do not diagnose, prescribe, or treat medical conditions. What coaching does is bridge the gap that conventional medicine often leaves — the space between receiving a diagnosis or recommendation and actually implementing sustainable change in daily life.

It is also not a one-size-fits-all wellness programme. There are no meal plans handed out, no rigid protocols to follow, no shoulds. Every client's path is unique — because every body, every life, and every set of circumstances is unique.

How I Work With Women.

"I do not tell you what to do. I help you figure out what is right for you."

I work with ambitious women — female founders, senior leaders, and executives — who are building extraordinary careers and are ready to stop treating their health as a trade-off.

These are women who are high-performing by every external measure, yet privately running on empty. They have optimised their calendars, their teams, and their strategies — but not their bodies. They know something needs to change. They just have not had the space, the support, or the right framework to do it sustainably.

If you have ever thought "I'll focus on my health once things calm down" — and things never calm down — this work is for you.


This is a collaboration

Above all else, this is a partnership. I am not here to hand you a protocol or tell you what you should be doing. I am here to think alongside you, hold space for what is difficult, and help you figure out what is genuinely right for your body and your life.

You are the expert on your own experience. My role is to ask better questions, offer a different lens, and help you cut through the noise of conflicting health advice to find what actually works — for you, in your life, with your schedule.

What that looks like in practice
  • Holding space — not filling it with advice
  • Asking the right questions — not offering the obvious answers
  • Working with your whole life — not just your plate
  • Focusing on root causes — not symptom management
  • Building sustainable micro-changes — not dramatic overhauls that do not last
  • Treating you as the expert on your own body — because you are

Progress is not always linear. There will be weeks that feel like breakthroughs and weeks that feel like setbacks. That is not failure — that is the reality of lasting change. My role is to stay alongside you through both.

"You were never meant to choose between your ambition and your health. We are here to prove it."
