Katie Stewart is a holistic nutrition practitioner helping people clear chronic acne through a root-cause, inside-out approach. Her own health journey led her to holistic nutrition, and now she helps others improve their skin, confidence, and mindset through deeper understanding of health and wellness. Let’s learn how she found her niche, and how she built a purpose-driven brand rooted in lasting results over trends and quick fixes.

Tell us about yourself!

Katie Stewart is a Registered Holistic Nutritionist and the founder of Katie Stewart Wellness, where she and her team help people with chronic acne clear their skin through an inside-out, root-cause approach built on five core areas: gut health, detoxification, hormonal balance, nervous system regulation, and skin barrier support.

Before nutrition, Katie spent 14 years in television, including behind-the-scenes work at Hockey Night in Canada and about five years as an on-air host at a local cable station. It was there, while working on a gluten-free cooking show around 2010, that her own health journey began. After removing gluten, her lifelong migraines disappeared. When she removed dairy, the stomach aches she’d carried since childhood went away too, and her skin started to change. That was the moment she understood how deeply food affects the whole body.

Katie has since worked with over 3,000 clients around the world. She co-hosts Keep It Clear, a top-ranked nutrition podcast on Apple, and has been a guest on dozens of others. Her work has been featured in over a dozen publications, including Glamour, OK! Life & Style, LA Weekly, and Woman’s World. In 2024, she received the Julie Daniluk Award. She is currently working on her first cookbook.

Why did you decide to work in this industry?

It started with my own health. When I was working on a gluten-free cooking show back in 2010, I removed gluten from my diet and the severe migraines I’d had since kindergarten went away. Then I removed dairy and my lifelong stomach aches disappeared and my skin improved. That was when I really understood that the food I was eating had a massive impact on my body. I’d always been drawn to the holistic idea of treating the whole person, and once I’d lived the difference myself, I wanted other people to know they had options.

What brought you to study holistic nutrition at CSNN?

 I’d fallen in love with food during my TV years. My producer actually pushed me to specialize, and food and nutrition was where my heart was. But it went deeper than a career move. After my own experience with food and healing, the holistic approach just made sense to me. I liked that it looked at the whole body instead of one symptom in isolation.

How did you choose your specialty/area of focus?

Acne is something I dealt with myself. I started breaking out in my early twenties after switching birth control, and having acne while working on-camera in television was really hard on my confidence and self-esteem. Back then, there was almost nowhere to turn. You could see a doctor and get a prescription, and that was pretty much it. I wanted other women to know that wasn’t their only option, and I wanted them to get their confidence back, because when you don’t have it, it touches every part of your life.

What does a typical work day look like for you?

Busy. I don’t do client coaching anymore. I have an incredible team for that, so my time goes into marketing and building the business. In a given week I’m recording my own podcast, guesting on others, writing captions and hooks, filming content, building carousels and lead magnets. I put out over 70 pieces of content a week across Instagram, YouTube, our podcast, three weekly emails, and Substack. On top of that I’m often building a new course, updating our website, working on ads, digging into analytics, and running the business side. I’m also always in some kind of training. Right now I’m doing an AI course for business.

What's your favourite thing about what you do?

The flexibility of working from home is wonderful, but the real answer is the ripple effect. I love when a client tells me this work changed their life, and then adds that now their husband or sister or kids want to be healthier too. One person making a change sends this incredible ripple out into the world. That’s what I’m most proud of.

What was your career "a-ha" moment?

Honestly, it was this past year, even after doing this for a long time. It was the hardest year we’d ever had in business, and it reminded me that entrepreneurship, just like health, isn’t a straight line from A to B. We’d grown and scaled really quickly, so a hard year was a shock to the system. But it taught me that there will be bumps and difficult seasons, and you have to be able to ride the wave to endure. I think I’d forgotten that, and living through it again was my real aha moment.

Was there a particular course at CSNN that motivated you towards your career path?

Working for Julie Daniluk, a fellow CSNN grad, while I was still a student. I started out as her videographer, and she became an incredible teacher and resource for me. When I saw the online business she was building, it clicked that I could do that too. That opened the door to everything that came next.

One of Katie's favourite client stories...

 One client who always stays with me is Emily. She wasn’t a quick success story. She was actually the client we worked with the longest, three full years. That’s exactly why her story matters to me. Most people give up on their health long before that if they aren’t seeing fast results, and that’s why they stay stuck. Emily kept going. She stayed positive through some really heavy personal things, and by the end she had a night-and-day transformation, not just in her skin but in her whole body and mindset. She ended up going back to school to study nutrition and is now a health coach in the UK. She’s proof of what happens when you give your health the time, patience, and consistency it needs.

What's your go-to recipe?

My go-to that I make constantly for my family is my rosemary apple turkey burgers. My kids love them and my clients’ families rave about them too. (My morning matcha latte has its own little cult following in my community, so that’s a close second.)

What are your 3 favourite things in your fridge/pantry?

My three pantry and fridge staples are ceremonial grade matcha powder, grass-fed meat sticks for quick protein between meetings, and homemade chia seed puddings I always keep on hand.

I chose CSNN because I loved what they stood for. They look at the body as a whole, which matched how I already saw health. It also mattered to me that I’d graduate with a diploma and not just a weekend certificate. I wanted real, in-depth knowledge, and CSNN gave me that foundation.
