Registered Dietitian vs. Nutritionist: The Difference Is Evidence-Based Practice

Registered Dietitian vs. Nutritionist: The Difference Is Evidence-Based Practice

When I first became a Registered Dietitian Nutritionist, I got a lot of questions from friends about my new profession, namely, “What’s a Registered Dietitian?!”

This video addresses that question and outlines the difference between RDs and “nutritionists,” including explaining a key guideline for RDs: evidence-based practice.

    Is Smart weighing scale, (which tells you about your age,muscle mass, fat etc )reliable?

    Really like the video. However, I had to turn my sound system way up to hear you. Your voice appears not have been recorded loud enough.

    So if I say that adopting a whole food plant based diet has been proved by endless studies to be the single best way to help prevent, treat, and even reverse some of our leading causes of death, including heart disease, type 2 diabetes, and high blood pressure, would you go vegan then? #itsscience.



  4. Joe Salemi on October 29, 2021 at 10:45 am

    No it’s not.

    They are many nutritionists who believe that RD’ have lobbyists who have secured their monopoly in nutrtional advice in the same manner as Doctors excluded Chiropractic doctors as not evidence based. Just look at the food that served in hospitals.



  6. Charlie Brown on October 29, 2021 at 10:47 am

    Well, according to a nutritionist… The proof is in the pudding!

    Where/what is your response to Bart Kay’s video on the problems that plague the nutritionist/dietitian career fields? Search him “Bart Kay- nutrition science watchdog”.



  8. Erika Martinez on October 29, 2021 at 10:50 am

    Im so excited to learn from you.



  9. OMGaNEWBIE on October 29, 2021 at 10:50 am

    The volume on this video is low. Is there anyway you can fix it?

    There is a very overweight certified nutritionist selling a 21 day plan for insulin resistance who used to be a beachbody coach, and she was actually at a healthy weight when she was using beachbody and drinking shakeology.

    For anyone watching this video and maybe reading this: RD is not the only certifying body for nutrition professionals. The ANA offers the Certified Nutrition Specialist to Masters Degree holders in Human Nutrition, Functional Medicine, etc. This is recognized by almost all states as certification required to legally call yourself a Nutritionist with "title protection." Additionally, many states offer state licensure guidelines that let you become certified at the state level or, in some instances, require it to call yourself a nutritionist. Common titles for a non RD nutritionist include LN (licensed nutritionist) and LDN (Licensed Dietary/Dietician Nutritionist). The scope of practice with this degree includes the ability to see patients, provide nutritional counseling, and even bill insurance. In order to earn the CNS and a state level license, one must obtain a Masters degree in Human Nutrition, complete 1,000 hours of supervised training, pass the CNS examination, and, if necessary, obtain state level licensure as well.

    Unfortunately, many RDs fail to include this in their explanations as to what the difference between an RD and nutritionist is which can lump in those who seek to get Board Certified through the ANA as those who take an online course and call themselves nutritionists.

    In all: the RD licensure pathway is one of two ways to obtain board and state licensure, obtain insurance, and get a license to practice. In many instances, the job roles can be interchangeable. In many instances, one patient may prefer a CNS vs an RD, too.

    Thank you for this advice, I’m inspired and really want to become an rd too! 🙂

    Hi Whitney. I’m a certified personal trainer & I want to know if a certication programme like Precision Nutrition makes me eligible to provide diet plans for my clients?



  15. Rachel Massie on October 29, 2021 at 10:59 am

    I get SO frustrated trying to learn about nutrition that is actually backed by science. Now I know the credentials to look for if I want to avoid the pseudoscience “woo” out there with outrageous claims lol. My husband suffers from chronic illness and I’m sure you already know EVERYONE seems to have an unproven magic cure to sell. 🙄 I don’t want magic promises about food, or crazy fad diets, just solid facts that help me make the best nutritional choices for us. Thank you for putting this out there! I subscribed to your channel now and I look forward to checking out more of your content.

    Thanks Whitney! Super helpful. There is so much stuff that is useless or downright harmful.



  20. Jonell Myers on October 29, 2021 at 11:03 am

    which university u attended to become a RD and is chemistry mandatory to enter the university to do dietetics?



  21. 7 Ren on October 29, 2021 at 11:04 am

    I used to be a skinny model and I was able to eat as much as I want.
    There was a medical accident and my body system was damaged very very bad.
    I don’t have fast metabolism anymore at least for years more.
    I was always in a good shape whatever I eat but now it’s not. so,
    Especially my belly fat and gut fat is dangerous level although I eat less than before so it
    means my body type is changed (slow metabolism, slow digest, like elder or people who originally had very slow metabolism). Also, I can exercise limited amount only.(walk and stretching. maybe muscle exercise not hard for short as possible.). I eat 1~4times a day so it was it was irregular. If I don’t eat carb, sort, sugar a lot(like chinese food or korean) I feel down but I regret every time after eat a lot as digestion is slow. But I started to change from today. My weight is always 13kg above compared before the accident. My stomach nerve was damaged too so
    it’s slow and always out. But when I eat less for long, it goes back in quite a bit.

    I just wonder what kind of eating style would be good for me and how often too..
    If it is and opinion, I would appreciate.
    thank you for reading!



  22. michele shertenlieb on October 29, 2021 at 11:09 am

    Love that you explained this so simply! I am seeing a RD right now and I love how what he tells me his evidence based and not myths!



  23. Lisa Young on October 29, 2021 at 11:09 am

    This is an excellent video that I’d love to include in my online course at City College of San Francisco. We are required that our video content have accurate captions to meet accessibility guidelines. Would you be willing to enable the Community Captions feature so I can provide appropriate captioning (which you would then need to approve)? Thanks so much



  24. Nathan Nyakayiru on October 29, 2021 at 11:09 am

    thanks Whitney for this clarification & congrats, the big part of the world know nothing or v.little about Nutrition & Dietetics including our fellow Health professionals. i’m Registered Nutritionist too and trying my best to get this sweetest Title …..i wish i w’d be in touch with u! if u do’t mind plz here’s my adress: nyakanathan@gmail.com ….thanks



  25. Brittany James on October 29, 2021 at 11:12 am

    This video is so disappointing. You’ve left out and entire industry of professionals, NUTRITIONISTS, who have completed a Master’s in Clinical Nutrition from an accredited university which is completely evidence based science and eligible to sit for board exams. The Certified Nutrition Specialist credential (CNS)is the most advanced certification for personalized nutrition practitioners. Certified Nutrition Specialists practice science-based personalized nutrition therapy to power people to health. Please be more responsible with your explanations so you don’t discredit ALL nutritionists and disrespect our education, hard earned degrees, and designations. Thank you.



  26. erika reyes on October 29, 2021 at 11:13 am

    Hi, my cousin was just diagnosed with cirrhosis. Obviously, her diet has yo change immediately and asap. Would you recommend her going to a nutritionist or RD? She needs guidance what to eat, how much, what’s good what’s not etc. Thank you. Any feedback would be appreciated.

  28. VerySeriousUser on October 29, 2021 at 11:16 am

    What happens to the registered dietitians that do not back up their statements with science? Like the ones recommending veganism and telling people that meat is bad.



  29. Kyree Cooper on October 29, 2021 at 11:18 am

    What would be an example of health practitioners that are not RD’s that relly on anecdotal stories to help clients? Would you say a Natropath would be one of those?



  30. A Daily Daughter on October 29, 2021 at 11:19 am

    Really respect your all your hard work. However, the truth is not usually open… Even to dietitians. Here’s an article about why one former Dietitian left the profession. https://keepfitnesslegal.crossfit.com/2018/02/07/why-giving-up-my-dietitians-license-was-the-healthy-choice/

  33. Kristi Billings on October 29, 2021 at 11:20 am

    Can you recommend an rd in San Antonio?
    Thank you



  34. jfp05 on October 29, 2021 at 11:21 am

    I don’t trust RDs anymore. RDs have to toe the line of the academy of foods and nutrition which receives money from Coca Cola ,Wendy’s, etc. RDs knowledge is outdated. RDs have to follow government guidelines which was corrupted by the food industry. RDs got me obsessed about the number in the scale and calories in vs calories out which backfires . RDs still think that eating fat is bad but they are ok with eating sugar and carbs. They are ok with eating 6 times a day to “control hunger “and “maintain metabolism” but the reality is the opposite. it’s sad that the RD is used and salesman for the processed food industry.



  35. Rick Done on October 29, 2021 at 11:22 am

    How do I know how much of every vitamin and minerals to take every day out of the substance that I intake?
    What is and optimal amount for males? I’m just looking for something that I can refer to like a book or app. Thanks 🙏🏾



  36. Moni on October 29, 2021 at 11:22 am

    There are accredited holistic nutrition programs who are also evidence based. I’m not talking a 3 month coaching program but a 1-3 year program full of science…Things change , cigarettes were once also considered healthy. There is also the evidence of obese nearly dead people walking around North America like zombies …so I’m not sure if dieticians and general doctors are doing such great jobs advising people on what healthy diet is. It is def not the standard American diet consisting of hospital sugary jello, white bread and low fat diet.



  37. Cleopetra T on October 29, 2021 at 11:22 am

    Dietitians in Australia do an extra year more than a nutritionist! Nutritionists are community based whereas dietitians are clinical based.
    I did nutrition and I swear it was a waste of a degree! No Jobs!!



  38. Elysian Hxney on October 29, 2021 at 11:23 am

    Ty now Ik that RD is better to me personally



  39. Dawn Kulan on October 29, 2021 at 11:25 am

    Great video! I’m going to study functional nutrition and I’m trying to select the right program for me. I’ve been practicing full time as a dental hygienist for 20 years and it will be the perfect transition. What advice do you have for me?



  40. IntroWellness | Wellness Reviews, Comparisons, and Information on October 29, 2021 at 11:28 am

    Love your focus on the BIG picture. Thanks for sharing!

    You are beautiful , njoyed your video



  42. Brionna May on October 29, 2021 at 11:32 am

    How can you find an RD? I’m wanting to go see someone but I don’t know how to go about it.

  45. Aaron Davis on October 29, 2021 at 11:33 am

    Thank you. Great explanation. Super smart and very pretty too. Love the sunflowers too. Jack Lulane said if the Earth grows it then eat it but if man made it then don’t eat it. Very succinct I think.

  47. Dream in Bronze ** on October 29, 2021 at 11:36 am

    The "evidence based practice" can be skewed (Big corporations work hand & hand with the government to have their privatized studies pushed to the forefront). That’s why Americans are in an obesity pandemic.



  48. Consider-It Health on October 29, 2021 at 11:36 am

    Yes, I’ve got this question so many times!



  49. Dietitian care on October 29, 2021 at 11:36 am

    And that practical live experience makes all the difference



  50. Felipe Cespedes on October 29, 2021 at 11:36 am

    I’m not impress by the "Evidence-Base" or "Science" by pharmaceuticals.

    Pharmaceuticals are harming Black, Brown, and Native people. Plus people in Africa and 3rd World Countries.

    Agenda, Greed, and Extreme profits override "Evidence-Base Science". Certain branches of "science" are dishonest and immoral.
