But we use coaching principles all the time!

Some housekeeping thoughts before diving in: I’m speaking about medical nutrition therapy. This can include certified nutrition specialists who are also credentialed nutritionists with extensive training, a board certification and only slightly different curriculum. I am also not putting down the pathway of nutrition coach or health coach but rather explaining the differences in scope and clarifying how an RD/CNS differs from personal trainers and nutrition coaches.

Most people don’t actually know what a dietitian is. Before I started my own journey, I didn’t either. I had only ever heard nutrition advice from doctors (briefly) or personal trainers (frequently). At one point, I even considered becoming a personal trainer or certified nutrition coach. But the deeper I dug, the clearer it became: an open-book, self-paced course can’t prepare someone to manage medical conditions, interpret labs, or build clinical nutrition interventions (nor is it legally able to).

There is absolutely value in behavior-change coaching — many people benefit from simple support and accountability. Dietitians utilize behavior-change based coaching throughout their practice. But coaching alone is not the same as practicing medical nutrition therapy (MNT). And that distinction is where the confusion starts.

Overcoming the confusion

The public confusion around nutrition is arguably at its highest. Because so few people understand what a dietitian actually is, they naturally assume we just hand out calories and macros. Or generic meal plans. Or supplements.

Nutrition, however, is a science, not just a hobby — and it changes dramatically when someone has a medical condition, takes certain medications, is recovering from surgery, or has complex symptoms. Safe, effective nutrition care requires:

• Years of formal education in biochemistry, physiology, and medical nutrition therapy
• Supervised clinical training
• Credentialing, licensure, and continuing education
• The ability to interpret labs, medications, and diagnoses
• Collaboration with a patient’s medical team

This is the difference between giving/receiving general advice and providing/receiving clinical care.

Below are regulated, clinical responsibilities that fall within our scope of practice — and outside the scope of a nutrition coach:

Clinical & Acute Care

• Manage nutrition in the ICU as advanced-care practitioners for high-risk, critically ill patients.
• Determine tube feeding and parenteral nutrition regimens based on labs, fluid balance, medications, and organ function.
• Evaluate lab work to identify nutrient deficiencies, metabolic abnormalities, and drug–nutrient interactions that require intervention.

Outpatient & Specialty Care

• Provide medical nutrition therapy for conditions like cardiology, GI disorders, kidney disease, endocrine disorders, or autoimmune conditions.
• Work directly with gastroenterologists, ENTs, neurologists, endocrinologists, surgeons, and primary care teams to adjust nutrition based on diagnoses and clinical goals.
• Treat complex patient populations: POTS, short bowel syndrome, diabetes, IBD, IBS, EDS, celiac disease, metabolic disorders, and more.

Sports Nutrition

• Develop evidence-based performance plans for amateur, collegiate, and professional athletes. Bonus if the athlete has a medical condition.
• Oversee fueling protocols for injury recovery, travel, tournaments, intense training cycles, and nutrient deficiencies.

Research & Industry

• Serve as subject-matter experts for product development (supplements, clinical formulas, medical foods).
• Design or advise on clinical research protocols involving nutrition interventions.
• Work in academia teaching future dietitians, physicians, nurses, and physician assistants.

This is not simply coaching. This is clinical care utilizing coaching principles.

Dietitians Don’t Just Write Meal Plans

Anyone can hand you a meal plan. It might even be helpful for a week or two. But real nutrition care goes deeper.

Dietitians are trained to:

• Assess your medical history, labs, symptoms, medications, and procedures
• Evaluate your nutrition risk
• Resolve barriers like appetite changes, GI symptoms, limited access to food, or chronic conditions
• Teach you why certain foods matter for your specific physiology
• Help you build sustainable habits that fit your real life

Our role isn’t to tell you what to eat — it’s to help you understand how nutrition interacts with your health, your body, your unique circumstances, and your long-term goals. We want to help you feel empowered to make these choices on your own.

Dietitians are Not Just for the Wealthy

Nutrition coaches [not all, but most] tend to serve people who already have time, access, money, and stable resources. Dietitians are covered by insurance, medicare and medicaid [depending upon the state plan] and can serve everyone.

Dietitians can work in:

• Hospitals
• Primary care and specialty clinics
• Food banks and community health centers
• WIC
• Rehab facilities
• Dialysis centers
• Long-term care facilities
• Public schools
• Universities and athletics departments
• Grocery stores
• Research hospitals
• Government programs

Certified nutrition specialists can work in many of these settings. And in every setting, we consider a person’s environment, income, food access, transportation, cultural background, and available resources. Access to dietitian services isn’t perfect — insurance coverage for MNT still has room to grow — but one clear advantage of working with a trained, credentialed nutrition professional is our presence across a wide range of clinical and community settings.

Our Work Can Move the Needle

Appropriate nutrition care can:

• Improve outcomes during hospital stays and reduce complications
• Improve symptoms, quality of life, and progression in disease states
• Support surgical recovery (pre- and post-operative)
• Enhance performance and body composition in athletes
• Support fertility, pregnancy, postpartum recovery, and infant feeding
• Reduce readmissions and improve long-term health trajectories

Everyone eats — but that doesn’t make everyone an expert. Nutrition directly affects physiology. Misguided advice can cause real harm. And high-quality guidance can dramatically improve health.

Final Thoughts

If you’re looking for nutrition guidance: Seek out a licensed, credentialed provider — a Registered Dietitian (RD/RDN) or Certified Nutrition Specialist (CNS). Titles are not interchangeable, and not all providers have the training to manage medical or complex nutrition needs. Take your time finding someone who fits your goals.

If you’re a fellow RD or CNS: Your work matters. We must continue to advocate for fair compensation. Keep sharpening your skills. Continue to show your value in clinical care, research, and leadership. Our field deserves to be recognized for the depth of training and expertise it requires.

Dietitians aren’t just nutrition coaches. We are clinicians. We are educators. We are scientists. And we are essential.
