Nutritionist vs Dietitian: What is the difference?


Although dietitians and nutritionists have similar functions, for the most part, they each have unique skill sets that help them thrive in different industries. 

 The title of Dietitian is protected by the law, but the term Nutritionist isn’t. 


The role of a dietitian is heavily regulated by legislation. Most states in the US have established licensure and certification requirements for dietitians in order to protect the consumers. In general, a registered dietitian needs to complete a bachelor's degree approved by the Academy of Nutrition and Dietetics (AND) as well as pass a national exam conducted by the Commission on Dietetic Registration (CDR). These requirements must be met before an individual can legally practice as a dietitian, or more precisely, a Registered Dietitian (RD). It is important to note that state agencies regulate the dietetics profession within their jurisdiction, and requirements may vary from one state to the next. 

Similarly, the educational requirements that must be met to earn the title of Nutritionist and legally perform nutrition counseling can vary widely across states. Some states allow individuals to perform personalized nutrition counseling with no licensure or registration required.  In other states, it is illegal to perform any sort of individualized nutritional counseling unless you are licensed or exempt. To practice in a regulated state, a nutritionist needs to acquire credentials from a nationally recognized nutrition licensing body. Both the AND and CDR offer nutritionist degrees and certifications. The Certification Board for Nutrition Specialists (CBNS) is another dedicated organization that authorizes the protected title of a Certified Nutrition Specialist for qualified and experienced nutritionists.

Since the title of Nutritionist isn’t always protected by the law, some people claim to be nutritionists when in fact they are not. As a consumer looking for nutrition guidance, always check credentials and licensing information. Every RD is a nutritionist, but not every nutritionist is a registered dietitian.  And while Nutritionists and RD's vary in scope of practice, both offer a wide variety of beneficial nutritional services.



Nutritionists generally work with healthy individuals, while dietitians tend to work with people who have specific medical needs. 



Dietitians are trained medical professionals that diagnose and treat dietary conditions while promoting overall nutritional health. Dietitians are also licensed to treat medical conditions, including eating disorders and chronic illnesses, by developing customized diet and nutrition programs. 

In comparison, nutritionists do not treat people with extensive medical illnesses. Instead, they offer nutrition advice to help people achieve their health and fitness goals through a healthier lifestyle.

Dietitians and Nutritionists have distinct, specialized courses of study.



Dietetics students take more courses focused on medical conditions and how to manage the conditions with nutritional therapy. These may include therapeutic diet preparation, clinical biochemistry, and medical nutrition therapy. On the other hand, nutrition students take courses that prioritize nutrition program planning and assessment in different environments. 

what does a nutritionist do


Nutritionists take a holistic approach to nutrition therapy and work towards their clients' health goals by promoting a balanced lifestyle. They offer customized nutrition advice to support the overall health and well-being of an organization or individual.

What exactly does a nutritionist do?


The typical responsibilities of a nutritionist include:

  • Communicating nutritional information and its importance to clients and communities

  • Assessing the clients' goals and needs
  • Developing and refining personalized meal plans and menus
  • Conducting market research and surveys to understand food choices and health trends

What happens when you see a nutritionist?


A nutritionist starts with an evaluation of your personal health goals, food preferences, cultural cuisine, dietary restrictions, and medical history. This comprehensive assessment is necessary to ensure that the advice you receive is right for you. Nutritionists also take into consideration your current lifestyle and understanding of nutrition. They then offer personalized advice and create balanced meal plans to help you achieve your goals and overcome barriers to change.

How much does a nutritionist appointment cost?


The average cost of a nutritionist appointment in the US ranges from $70 to $100. The prices for an initial consultation vary between $100 and $200, and you can expect to pay $50 to $150 for each follow-up visit. 

Types of Nutritionists


Many different types of nutritionists offer specialized advice for particular groups. Each of the roles has distinctive work environments and expertise.

A Nutrition Consultant develops customized eating plans that promote a healthy Body Mass Index (BMI) and boost the body's immune response and metabolism.

A Holistic Nutritionist takes a preventive approach to health problems and seeks to improve the physical, mental, emotional, environmental, and spiritual aspects of a person's health.

A Functional Nutritionist reviews several lifestyle factors such as diet, sleep, stress, and fitness to create a plan that emphasizes high-quality nutrition and gradual behavior modifications.

A Certified Nutrition Specialist has the most advanced nutrition science certification of the profession. They provide science-based personalized nutrition therapy and guide clients to smarter food choices. ‌


what does a dietitian do


Registered Dietitians (RDs) counsel individuals and industry stakeholders on the best practices in food and nutrition. Dietitians are often an integral part of multidisciplinary teams that work together to treat conditions like eating disorders, malnutrition, diabetes, chronic fatigue, and bowel disorders.

What does a dietitian do?


The primary day-to-day responsibilities of a registered dietitian are:

  • Conducting nutritional assessments of patients with complex medical conditions
  • Creating custom diet plans for these individuals
  • Reviewing and improving existing nutrition plans
  • Maintaining accurate records of all assessments and interventions 
  • Advising on food and nutrition-related policy developments
  • Providing education on standard and non-standard nutritional requirements


Types of dietitians


Clinical dietitians are employed exclusively by healthcare providers and work closely with medical professionals. They provide personalized nutrition therapies to patients diagnosed with complex health conditions.

Food Service dietitians work in environments that call for large-scale meal planning. They are in charge of the entire food service process and develop healthy menus for restaurants, company cafes, and school canteens.

Pediatric dietitians specialize in designing nutritional programs for children and adolescents.

Sports dietitians help athletes and competitive sports professionals achieve optimal performance with the proper diet and nutrition.
