Apply to the college or university of your choice that offers a bachelor of science (B.S.) in Natural Nutrition. Many colleges offer this kind of degree, including Kaplan University, South University Online, DeVry University and Walden University, among others. Research these schools to see which one best fits your lifestyle, such as the type of students who go there, the dorm situation, the types of classes you will be required to take, the tuition cost and other factors that are important to you. Apply to more than one school in case the school of your choice does not accept you.
Meet with a career counselor in the university of your choice to discuss which classes you need to take to graduate with a B.S. in Natural Nutrition. The counselor can guide you on the proper number of courses to take per semester, which courses to take first and when you can reasonably expect to graduate.
Sign up for the proper courses each semester according to the registration system in your school. Attend classes and do well because most of the information you are taught will help you care for your future clients. Keep clear notes of all of the practical information you are taught so you can easily look things up when you are a practicing nutritionist.
