About Fiona

Welcome! I’m Fiona Halar. A vegan nutritionist, an accredited exercise scientist and personal trainer.

I believe that how we live our lives and what we put into our bodies has a profound effect on our health, our planet and all who inhabit it. That’s why I’m committed to helping others lead healthy, ecologically sustainable and compassionate lives.

As a vegan health professional, my goal is to help you make healthier diet and lifestyle choices, with nutrition and exercise advice backed by evidence-based science.

I wasn’t always passionate about leading a healthy lifestyle.

I used to work in the corporate world. I lived a life of excess. I used to work hard and played hard. I was overweight, and I very rarely got enough sleep or rest. My job was stressful. My diet was bad. I used to go out a lot and binge drink.

I thought I was invincible, but eventually, my health deteriorated. My frustration grew as I battled chronic illness and fatigue. I had some good days, but mostly I was exhausted. I couldn’t work anymore.

I tried many different conventional and alternative therapies. In the end, it was my total commitment to living a natural, vegan lifestyle, which incorporated yoga, meditation and exercise that helped me heal. I also discovered my real passion—helping others discover their innate ability to thrive on a whole foods plant-based (vegan) diet.
