What is Nathalie Mat’s approach to nutrition?

Nathalie takes a food-first, Health at Every Size (HAES)-informed approach. She views a dietitian’s role as a facilitator translating current research into realistic, practical lifestyle changes rather than prescribing rigid diets. Supplements are recommended only where there is a genuine deficiency or increased requirement.

I use up-to-date research and guidelines to shape my work. I am a Health At Every Size (HAES)-informed dietitian, meaning I strive for health beyond the number we see on the scale. You can opt out of being weighed in my practice. I view the role of a dietitian as a facilitator, translating new research and scientific information into realistic and practical lifestyle changes for my clients. I am also your nutrition cheerleader. I know life is difficult and that you are not a robot. I will support you through the entire journey, not just the peachy parts.

I prefer a food first approach. This means that I believe in getting most nutrients from food first and only using supplements where the person has a deficiency, the diet is deficient or if a person has greatly increased requirements.
