Certified Nutritionists (NNCP, RHN) and Registered Dieticians (RD) both provide responsible nutrition advice to help you maintain or improve your health.  Whether that be to help you find a healthy weight, manage current health conditions or educate you in the prevention of disease.  Their duties are very similar in private practice.   The main difference is their roles within the healthcare system and the educational path to attain their qualifications. The training of a holistic nutritionist is geared towards nutritional counselling, education and working in a private practice.  It also encompasses broader topics of integrated wellness such as life style and self care. Dieticians are regulated healthcare professionals with training geared towards both private practice and clinical work within a hospital setting, research and public health.
To choose a practitioner that is right for you consider their overall experience and what level of ongoing support they provide.  Having support along your journey is essential to lasting success. Ensure that they are committed to ongoing professional development and, most importantly, that their philosophies around wellness align with your own.
