The profession of dietetics has its roots in the early 20th century, when the importance of nutrition in healthcare began to be recognized. The first dietetic association, the American Dietetic Association (now known as the Academy of Nutrition and Dietetics), was founded in 1917. Throughout the 20th century, the field of dietetics continued to evolve and expand, with the development of standardized education and training programs, as well as the establishment of licensing and certification requirements. Today, dietitians are recognized as essential members of healthcare teams, playing a crucial role in disease prevention, management, and treatment through the application of evidence-based nutrition practices.

How It Works

Dietitians are nutrition experts who utilize their knowledge of food and nutrition to promote healthy eating habits and help individuals achieve their health goals. They assess a client's dietary needs, considering factors such as age, health conditions, and lifestyle. Based on this assessment, they develop personalized meal plans and provide education on nutrition, portion control, and healthy food choices. Dietitians also monitor progress, make adjustments to the plan as needed, and offer ongoing support and guidance to ensure long-term success. They may work in various settings, including hospitals, clinics, private practices, and community health organizations.


When working with a dietitian, it's essential to be open and honest about your dietary habits, health concerns, and goals. Implementing the recommended changes to your diet and lifestyle may require significant effort and dedication. Some individuals may find it challenging to break long-standing eating habits or make time for meal planning and preparation. It's crucial to communicate any difficulties or concerns with your dietitian so they can provide appropriate support and guidance. Additionally, it's important to verify that the dietitian you choose has the necessary certifications and experience to meet your specific needs.

How Much It Costs

The cost of working with a dietitian can vary depending on factors such as location, experience, and the type of services provided. On average, an initial consultation with a dietitian can range from $100 to $200, while follow-up sessions may cost between $50 and $150 per visit. Some dietitians may offer package deals or discounted rates for a series of sessions. Health insurance plans may cover some or all of the costs associated with dietitian services, particularly if the services are deemed medically necessary. It's best to check with your insurance provider to determine your coverage.

Virtual & Online Options

Virtual or online dietitian services offer several advantages over traditional in-person options. Online consultations provide greater flexibility and convenience, as clients can access services from the comfort of their own homes, eliminating the need for travel. This can be particularly beneficial for individuals with busy schedules or limited mobility. Online platforms also allow for more frequent check-ins and support between sessions. However, in-person consultations may be preferred by some individuals who value face-to-face interactions and hands-on guidance. Local dietitians may also have a better understanding of community resources and food options available in the area.


To become a registered dietitian (RD) or registered dietitian nutritionist (RDN) in the United States, individuals must complete a bachelor's degree or higher from an accredited college or university, with coursework approved by the Accreditation Council for Education in Nutrition and Dietetics (ACEND). They must then complete an ACEND-accredited supervised practice program, typically lasting 6-12 months. After completing the educational and practical requirements, individuals must pass the Commission on Dietetic Registration (CDR) examination to obtain the RD or RDN credential. Some states may have additional licensing requirements for dietitians.

Complementary Practices

Complementary practices that synergize well with the work of dietitians include exercise and fitness training, stress management techniques like mindfulness or yoga, behavior modification and goal setting, and ongoing health monitoring with a primary care physician. Combining personalized nutrition plans from a dietitian with these complementary practices can enhance overall health outcomes and promote sustainable lifestyle changes.

Practitioner Types

Registered Dietitians (RDs) and Registered Dietitian Nutritionists (RDNs) are the primary professionals in this field. They hold a bachelor's degree, complete an accredited supervised practice program, pass a national examination, and maintain continuing education requirements. Some RDs and RDNs specialize in specific areas such as pediatric, renal, oncology, or sports nutrition. Other related practitioners include Certified Nutrition Specialists (CNS), Certified Clinical Nutritionists (CCN), and Certified Health Coaches who may provide general nutrition advice but cannot offer medical nutrition therapy.
