Aspiring dietitians need a firm foundation in natural sciences, including chemistry, microbiology and anatomy, as well as extensive knowledge of nutrition principles and applications. Furthermore, dietitians can benefit from soft skills like problem-solving, analytical reasoning and communication skills.4
Dietitians need to be able to apply their scientific knowledge in a way that seems approachable and feasible for their clients. In other words, they need to help their clients see that healthy eating really can improve their health. In order to experience a comprehensive curriculum that incorporates these technical and soft skills, you may want to consider the following degree programs:
People who are coping with a serious or chronic medical condition, such as heart disease or diabetes, may feel overwhelmed and have difficulty adjusting to their new life circumstances. It’s the job of a dietitian to help these individuals feel empowered to take charge of their health by making healthier lifestyle choices.

Dietitians are registered professionals who have completed a specific educational path, including a degree in dietetics, supervised practice and pass a national exam. They can provide medical nutrition therapy and work in clinical settings.
Nutritional science is an area of study that focuses on how dietary choices affect health. A dietitian applies their knowledge of diet and nutrition to help individuals make healthier dietary choices and recover from illness. These professionals may also examine how healthy nutrition choices can reduce the risk of disease and optimize wellness.
In the U.S., poor nutritional choices contribute to about 678,000 deaths each year.2 A diet that is too high in calories, sugar and saturated fats and lacks sufficient healthy foods raises the risk of some of the most common causes of death, including heart disease, diabetes and obesity.2 As a dietitian, you could work toward helping others make positive changes that may help improve their health.

If you’re curious about how to become a dietitian, it’s important to understand that requirements vary by state.1 Before beginning your postsecondary education, research the specific licensing or certification requirements in the state where you plan to work, as many states mandate that dietitians be licensed. This can help ensure you meet the necessary criteria and can practice legally in your chosen location.
If you know you want to become a dietitian, building a strong science background can be beneficial. Focus on excelling in biology and chemistry and consider adding science electives such as anatomy and physiology, if available. Additionally, since dietitians often interact with clients and help them make healthier lifestyle choices, taking courses in communications and psychology can also be advantageous.
Aspiring dietitians typically need at least a master's degree.1 This depends on state licensure requirements, which vary. If your state has licensure requirements for dietitians, be sure the degree program(s) you choose will allow you to meet them. In some cases, an internship or other supervised training is offered as part of the degree program. Look for a bachelor's or master's degree that focuses specifically on nutritional science, dietetics or food and nutrition.1
Many dietitians receive practical experience through supervised training, such as internships, either during or after college. Additionally, some states require this type of supervised experience as part of their licensure criteria.1 An internship or similar training can offer work opportunities that can be invaluable as you begin your career path.
If you choose to obtain certification as an RDN, you might qualify to apply for dietitian jobs without first obtaining work experience beyond your supervised training. Job requirements vary from one employer to the next. If you find that you need some more work experience first, you might consider looking for a job assisting and educating patients under the supervision of a licensed, practicing dietitian.4
Your state may require you to obtain a dietitian license.1 The needed credential to be a dietitian is the RDN credential from the Academy of Nutrition and Dietetics’ credentialing agency, the Commission on Dietetic Registration. To obtain the RDN credential, you must earn a minimum of a master’s degree and complete professional experiences.1 At GCU, these professional experiences are integrated into the master’s program. Another common credential is the Certified Nutrition Specialist (CNS) designation.1
A person’s career path toward becoming a dietitian can often depend on state licensing requirements. Even if your state lacks licensing requirements for dietitians, you may find that obtaining a certification from a professional group can help enhance your future career.1
Dietitians are charged with promoting the health and wellness of their clients by applying their knowledge of nutritional science and food. Dietitians typically work one-on-one with their clients, providing assessments and developing personalized nutritional plans. However, they may also design and lead group programs intended to raise awareness of the importance of healthy nutrition. What do dietitians do on a day-to-day basis? Their tasks can vary but generally include the following:3
Assessments
Dietitians first assess their clients’ nutrition-related medical conditions and typical dietary choices.
Diagnostics
Health coaches may recommend their clients undergo bloodwork to check for vitamin and mineral deficiencies.
Follow-Up
Dietitians meet with their clients periodically to assess their progress and provide follow-up guidance.
Group Programs
Some dietitians develop and lead group programs. They talk to groups about healthy eating habits or managing certain health conditions through diet.
Education
Wellness coaches are educators who help their clients understand the “why” behind healthy eating habits.
Meal and Nutrition Plans
These professionals develop personalized nutrition and meal plans for their clients, considering food preferences, budget and other factors.
Collaboration
These health professionals often need to collaborate with their clients’ healthcare providers to provide holistic management of health conditions, such as diabetes or heart disease.
Food Program Planning
You may work in food service settings, like hospitals and schools, where they plan food programs that meet certain diet restrictions.
In general, dietitians provide client-centered services designed to promote health by reducing the risk of disease or by managing existing health conditions.
Some dietitians may seek professional certifications to specialize in areas like sports nutrition, health coaching or holistic nutrition.4 With sufficient work experience and additional credentials, dietitians may also pursue career progression by directing nutritional services, teaching nutrition science or conducting clinical nutrition research.8
