Dietitians are food and nutrition experts who assess nutritional needs, develop meal plans, and provide medical nutrition therapy for diseases like diabetes, kidney disease, and eating disorders. They complete bachelor’s degrees in dietetics, supervised practice programs (typically 6–12-month internships), and pass national registration exams. Education is transitioning to requiring master’s degrees by 2024. RDNs earn median salaries of $61,000-$65,000 and work in hospitals, outpatient clinics, long-term care facilities, schools, public health departments, and private practice. Specializations include clinical nutrition, pediatrics, sports nutrition, renal nutrition, and oncology. State licensure is required in most states. Work involves patient counseling, developing nutrition care plans, and collaborating with healthcare teams.
Athletic trainers prevent, diagnose, and treat muscle and bone injuries. They work with athletes and active individuals providing injury evaluation, rehabilitation, and emergency care. Entry requires bachelor’s or master’s degrees in athletic training plus BOC certification. Athletic trainers earn $48,000-$55,000 and work in schools, colleges, professional sports, hospitals, clinics, and military settings. The field is transitioning to require master’s degrees for entry.
Dietetic technicians assist dietitians with food service management, nutrition education, and patient care. They need associate degrees and national certification (DTR). Technicians earn $30,000-$40,000 and work in hospitals, nursing homes, and food service operations. This role provides entry to nutrition careers with less education than RDN.
Exercise physiologists develop fitness and exercise programs for patients recovering from chronic diseases and injuries. They conduct stress tests, create rehabilitation plans, and work with cardiac and pulmonary patients. Most positions require bachelor’s degrees with some requiring master’s degrees. They earn $47,000-$52,000 and work in hospitals, cardiac rehabilitation centers, and fitness facilities.
Kinesiotherapists use exercise and education to treat patients with movement dysfunction from disease, injury, or disability. They need bachelor’s degrees and national certification. Salary ranges from $45,000-$60,000. Work primarily in VA hospitals and rehabilitation centers.
