What is a Registered Dietitian?

A Registered Dietitian (RD) is a uniquely trained and educated medical professional that specializes in nutrition and dietetics. The Commission on Dietetic Registration (CDR) of the Academy of Nutrition and Dietetics (AND) sets a rigorous standard of education that Registered Dietitians are required to meet to ensure they have the proper expertise and experience in their field.

What does a Registered Dietitian do?

A Registered Dietitian provides specialized counseling and care in the treatment of obesity while adhering to strict dietary guidelines. By assessing the nutritional needs of each individual client, a dietitian is able to provide nutrition plans dedicated to long-term weight management that are customized uniquely for each patient.

How can a Registered Dietitian help me?

A Registered Dietitian, in combination with a team of qualified health professionals, can assist individuals struggling with mild, moderate, or severe weight loss by helping create and maintain a customized long-term weight management plan. By understanding your dietary habits and lifestyle, a dietitian can recommend a personalized nutrition plan that will help you achieve optimal results. Using non-surgical and advanced individualized methods and monitoring, our Registered Dietitian can help you reach and sustain a healthy weight, and more importantly a healthy lifestyle.
