“Not a Licensed Dietitian”: The Sentence a Missouri Nutritionist Owes You
Revised October 20, 2026
How do I know if I need a nutritionist?
Book when a diagnosis puts food in the treatment plan - diabetes, kidney disease, high cholesterol, celiac, allergies, pregnancy, cancer care - or when a pattern won’t change after several honest tries. For a diagnosis, see a licensed dietitian: in Missouri nobody may use that title without a state license, and on Medicare with diabetes or kidney disease, a referral can make the visits free.
Keep reading ↓“I’m going to put in a referral to nutrition.”
That’s the whole instruction. Your doctor says it with one hand already on the door. The paper on the exam table crackles as you sit up, the printout in your lap has a word on it you’ll be typing into your phone in the parking garage, and nobody tells you who you’re supposed to see, what it costs, or that in Missouri the person who gives you diet advice may owe you a disclosure before they say a word.
Maybe it’s a celiac diagnosis, and the tray of toasted ravioli at your niece’s graduation party in Webster Groves, golden and still hot, is suddenly a question you can’t answer. In St. Louis the next move is shorter than it looks: one call to Jefferson City to check a license, one call to a hospital dietitian’s office on Olive Boulevard, and, if you’re on Medicare, one question for your doctor before the year runs out.
How do I know if I need a nutritionist?
The clearest signal is a diagnosis that food now helps manage: diabetes, kidney disease, high cholesterol, celiac, food allergies, pregnancy, cancer treatment or a digestive condition. The second is a pattern you haven’t been able to change alone after several honest tries. Either one is reason enough to book, and for a diagnosis, book a licensed dietitian.
The second reason is every bit as legitimate as the first. You know roughly what you should be doing, it isn’t happening, and the cause is usually the shape of your week - the double shift, the drive-through at nine at night, the kid who only eats beige - not a shortage of willpower. And if food has started to feel like a test you keep failing, talk to a professional now. Disordered eating is treated better early than late.
If the person at your table is pregnant, a new mom or a child under five, and money is tight, there is a second door most St. Louis families walk right past. WIC here is run by Betty Jean Kerr People’s Health Centers, and nutrition education and counseling come with the food. You walk in with the diaper bag cutting into your shoulder and a toddler pulling at your sleeve, and you walk out with a plan. Call 314-361-5728, or go to the clinic at 5701 Delmar Boulevard. Tell your sister. Most people think WIC is groceries only.
The Missouri rule almost nobody knows
Under Missouri’s Dietitian Practice Act, nobody may call themselves a dietitian unless they hold a state license. A licensed dietitian can practice medical nutrition therapy, which the statute defines as nutrition care for the treatment or management of a disease or medical condition. That is the clinical work your doctor meant.
Now the part worth saying out loud at your next family dinner. The same law lets a credentialed person who isn’t a licensed dietitian give nutrition advice within their credential’s scope - but before they do, they owe you their name and title, their business address and phone, a statement that they are not a dietitian licensed by the state of Missouri, a statement that their advice may be considered alternative care by licensed practitioners, and their qualifications, including education, training and experience.
So if you’re sitting across from a supplement shelf and a “nutritionist” nameplate and nobody has mentioned a license, ask. Out loud. The good ones answer before you finish the sentence. The state’s Committee of Dietitians takes requests for verification of licensure at 573-522-3438.
What happens at the first appointment with a nutritionist?
Here’s how one St. Louis hospital system spells it out. At Mercy Dietitian Services on Olive Boulevard, you come in by referral from your doctor, and the first appointment usually takes 60 to 90 minutes. Follow-ups typically last 15 to 30. No blood work is done. The dietitian takes a diet history, uses visual aids to teach portions and labels, and sets up a meal plan if your doctor’s orders call for one. Scheduling is 314-251-8885, and Mercy’s own page notes that many insurance companies cover nutrition counseling, referred to as medical nutrition therapy - so check your benefits before you dial.
Two details most people miss. You may bring someone with you, especially the person who does the cooking or the grocery shopping - the one who actually stands in the cereal aisle reading boxes. And if there are specific foods you want to talk about, bring the labels: the crinkled granola bar wrapper from your bag, the jar of pasta sauce from the pantry. Keep a few days of what you eat and drink, too, written down honestly. Nobody is grading you. A plan built on the polite version won’t survive a Tuesday.
The free hours Medicare patients leave on the table
If you are on Medicare and you have diabetes or kidney disease, or you’ve had a kidney transplant in the last 36 months, Part B covers medical nutrition therapy. A doctor has to refer you. Only a registered dietitian, or a nutrition professional who meets certain requirements, can provide it. And you pay nothing for it if you qualify.
The coverage is 3 hours in the first calendar year, then 2 hours of follow-up each calendar year after that. The catch is one quiet sentence on Medicare’s own page: those hours can’t be carried over to the next calendar year. A referral that sits unopened in your patient portal until the holidays is time with a dietitian you already had coming, gone. If a parent of yours on Medicare just got the diabetes talk, that is the sentence to text them tonight.
If you came by referral, a dietitian reads your labs next to what you eat, not in isolation. Some visits include a scale. If stepping on one makes your stomach drop, say so at the start; a good practitioner works around it. The visit ends with two or three changes that fit the life you just described and a follow-up date, because the first plan is a draft.
Is it better to go to a dietician or nutritionist?
For anything with a diagnosis attached, a licensed dietitian. The RD and RDN credentials sit on a degree, supervised practice and a national exam, and in Missouri the dietitian title itself requires a state license. “Nutritionist” on its own can mean almost anything: some people using it hold graduate degrees and serious board certification, others finished a short course. From the sidewalk, the signs look identical.
That doesn’t make one good and the other bad. It means one title tells you what training happened and the other tells you to ask. For general habits and accountability, a well-qualified nutritionist can be a fine fit, as long as you’ve heard what the qualification is. Everything on this page is general information, not medical advice; anything specific to your health belongs with your own clinician.
What a dietitian can do that a nutritionist often can’t
Medical nutrition therapy for a diagnosed condition. It is a clinical process, not dressed-up advice: assessment, a nutrition diagnosis, an intervention, then monitoring against your labs. In diabetes care, kidney care, cancer treatment and eating disorder treatment, it is the work that gets documented in your chart, and it is the reason referrals and insurance billing run to dietitians. A physician needs a credential they can verify and a note that comes back into the record.
One sentence on the phone sorts it out: are you a registered dietitian, and are you licensed in Missouri? A pause at that question is the most useful thing you will hear all day. Weighing hypnotherapy for the same habits? Ask that license question there too, and read what to know before you book a hypnotherapist in St. Louis.
Check the license before you check the calendar. Browse nutritionists across the metro on St Louis Near Me Directory, ask each one the same short list of questions below, and compare what you hear back. If you’re on Medicare with diabetes or kidney disease, ask your doctor for the referral before you call anyone.
If you’re the dietitian, the wellness coach or the one-person practice these patients should be calling, the referral they just got is a search they are about to run. Put your license, your specialties and your insurance answers where they’ll find them and get more customers - list your practice.
Do dietitians give you meal plans?
Sometimes, on request, but a rigid chart is rarely the goal. More often you get a framework: what a balanced plate looks like for your situation, portion guidance, swaps for food you already buy, and a short list of changes to try before the next visit.
A seven-day chart works until the first day that breaks - the sick kid, the meeting that runs late, the Thursday you don’t feel like the salmon past-you planned. Then the whole sheet on the fridge starts to feel like a verdict. A plan you can live with works at a restaurant you’ve never been to, at a ball game, at a drive-through at nine at night, and it has room for the food you love. If a written plan helps you, ask for one. If a chart would make you anxious, say that instead.
People are asking
How often should you see your nutritionist?
On Medicare, after the first year’s 3 hours of nutrition therapy you can get up to 2 hours of follow-up each calendar year, and if your doctor decides a change in your medical condition requires a change in your diet, they can refer you for more hours beyond that. So the morning a new lab result lands in your patient portal and your stomach drops, ask your doctor about that referral instead of rationing the hours you have left. With diabetes, ask about the benefit sitting right next to it: Medicare Part B also covers up to 10 hours of diabetes self-management training, 1 hour one-on-one and 9 in a group, which may include tips for eating healthy and monitoring blood sugar, and after the Part B deductible you pay 20% of the Medicare-approved amount for that one.
How insurance, referrals and price actually work
It varies by plan, and the only reliable answer comes from your own insurer. Call the number on the back of your card and ask four things, then write down who you talked to and when:
- Is medical nutrition therapy covered under my plan?
- Do I need a referral first?
- How many visits are allowed in a year?
- Is this provider in network?
If you pay out of pocket, four things move the price: the practitioner’s credential and experience, how long the session runs, whether you’re buying one visit or a block, and whether insurance is involved. First visits run longer than follow-ups and are usually priced differently. Ask what one visit costs before you agree to a package of six.
A good plan has room in it for a cold scoop on a hot night. See gelato versus ice cream in St. Louis.
What should you ask before you book?
Credentials first, everything else second. This takes about five minutes on the phone and heads off most of the problems people hit three appointments in.
- Are you a registered dietitian, and are you licensed in Missouri?
- If not, what credential do you hold, and what did earning it require?
- Have you worked with my condition before?
- Do you take my insurance, and will you bill it directly?
- How long is the first appointment, and how long are follow-ups?
- Can I contact you between visits, and is that included?
- What do you do if I’m not making progress?
Then the one question that tells you the most: what does success look like in three months? An answer about your labs, your energy and habits you can keep is clinical work. An answer about a number on the scale and how fast is a sale. Same for detoxes, cleanses, supplement lines sold in the same room as the advice, and tests that promise to reveal hidden sensitivities.

Frequently asked questions
Is it better to go to a dietician or nutritionist?
For anything with a diagnosis attached, a licensed dietitian. In Missouri nobody may call themselves a dietitian without a state license, and the license covers medical nutrition therapy for a disease or medical condition. “Nutritionist” can mean a graduate degree or a weekend course, so for general habit coaching a well-qualified one can work, as long as you’ve asked what the qualification is.
What can a dietitian do that a nutritionist cannot?
Provide medical nutrition therapy for a diagnosed condition and be recognized by referral networks and insurance. Medicare, for example, says only a registered dietitian or a nutrition professional who meets certain requirements can provide its medical nutrition therapy services. In Missouri, a credentialed advisor who isn’t a licensed dietitian must tell you so, in a statement, before advising you.
What happens at the first appointment with a nutritionist?
You talk more than you expect. The visit usually runs longer than a routine doctor appointment and covers a health intake, a detailed diet history, any labs from your referral, and your goals and schedule. Bring medications, supplements, recent labs and the referral. Most people leave with two or three specific changes and a follow-up date.
What’s the average cost to see a nutritionist?
There is no single figure; it depends on the credential, session length, single visit versus package, and insurance. One clear exception: if you’re on Medicare with diabetes or kidney disease and your doctor refers you, you pay nothing for covered medical nutrition therapy if you qualify. Everyone else should ask about coverage and single-visit pricing on the first call.
What’s a good question to ask a nutritionist?
“Are you licensed as a dietitian in Missouri?” comes first. Then: “What does success look like in three months?” Labs, energy and habits you can keep describe clinical work; a scale number and a promise about speed describe a sale.
Do dietitians get called doctors?
No. In Missouri, dietitians are licensed under their own law, the Dietitian Practice Act, to practice dietetics and medical nutrition therapy. A doctorate in nutrition is a different thing from being a physician. In practice a dietitian works alongside your doctor, reading the same labs and writing into the same chart.
