Lesley Nickleson, Functional Dietitian | Root-Cause Healing & Personalized Nutrition

Hello- I am Lesley — a Registered Dietitian with over 27 years of clinical experience and one of few in Canada with Board Certification in Integrative & Functional Nutrition.

I help adults get to the root cause of their symptoms so they can finally feel well — improving digestion, metabolism, energy and overall vitality through personalized, evidence-based care.

My approach blends functional nutrition science with compassionate coaching, so you not only understand what to do, but also why it works for your unique body.

Here’s what you can expect when working with me:

1️⃣ Clarity & Confidence You’ll learn how to eat for your body — not a trend or template. Together, we’ll identify what, when and how much to eat for balanced energy, improved digestion, and sustainable results.

2️⃣ Personalized, Root-Cause Approach I don’t believe in one-size-fits-all. Using tools like MSQ scoring, comprehensive diet & lifestyle review and targeted lab testing when needed, I uncover what’s truly driving your symptoms and build a plan that works for you.

3️⃣ Real Food, Functional Focus Every plan includes nourishing, whole foods and targeted functional nutrition strategies — from gut restoration and detox support to hormone and metabolic balance.

4️⃣ Ongoing Support Healing takes time, and you don’t have to do it alone. I’ll guide you step-by-step, adjusting as we go to ensure real progress and lasting change.

Areas of Focus

• Gut Health & Digestive Disorders: IBS, Crohn’s, bloating, sensitivities

• Metabolic & Cardiometabolic Health: blood sugar, cholesterol, fatty liver

• Detoxification & Anti-Candida Support:  address auto-immune conditions

• Hormone & Weight Balance:  perimenopause, metaboliic support

• Cancer Recovery & Inflammation Support: functional foods and personalized healing nutrition

If you’re ready to stop guessing and start healing, I would love to help you take that next step. Book your free consultation today and begin your journey toward restoration and optimal health.
