About Me

I'm proud to call myself a South African-Kiwi! Born and raised in Cape Town, I completed my Bachelor of Science and Honours degree in Nutrition & Dietetics at the University of Cape Town, qualifying as a dietitian in 1995. Later that year, I moved to New Zealand, where I earned a Masters in Sports Nutrition and a Doctorate focused on weight loss.
I currently work at AUT as a Professor of Nutrition, while also maintaining a private nutrition practice. My career has allowed me to evolve alongside advances in nutrition science. Today, I’m a strong advocate for a whole-food approach—encouraging people to reduce processed carbohydrates and include more protein and healthy fats.
I believe nutrition should be tailored to each individual, as macronutrient needs vary widely. My philosophy is grounded in sound science and practical experience, and I see this as the path forward to improving health outcomes and addressing issues like obesity and Type 2 diabetes.
While I work with a range of clients and goals, my main areas of expertise are metabolic health and sports performance, particularly using whole-food and carbohydrate-restricted approaches.
At AUT, I teach across the Sport & Recreation Programmes and conduct research within the Human Potential Centre. AUT is committed to academic freedom and supports research at the cutting edge—even when it’s controversial.
Here is my academic profile.
