Top 7 Dietitian Networks Clinics Can Partner With in 2026

For medical weight loss, wellness and aesthetic clinics. Updated October 2, 2026 · Prepared by Prospyr. Prospyr makes practice software, not nutrition services, and none of the companies below is a Prospyr product or partner. Each summary reflects what the company publishes on its own website, checked October 2026. Insurance coverage, referral steps and session prices change, so confirm everything in writing before you send your first patient.

What does a dietitian network do for a clinic?

A dietitian network gives your patients access to registered dietitians without you hiring one. Most are telehealth companies that accept a referral from your provider, contact the patient within a day, check insurance, match them with a registered dietitian nutritionist (RDN), and send visit notes back to your team. For a weight loss or GLP-1 program, that means patients get nutrition counseling between your visits, often billed to their own insurance. The differences that matter: how they take referrals, what you hear back, and what the patient pays.

The 7 dietitian networks at a glance

How we chose this list

We looked for companies a clinic can actually work with, not consumer apps. Each entry had to meet at least three of these, on its own website:

• A clear provider path. A referral form, fax line, EHR connection or staffing contract a clinic can use.
• Registered dietitians. Care delivered by RDs or RDNs, not unlicensed coaches.
• Published cost terms. Insurance acceptance, a self-pay rate or a stated coverage figure.
• Something back to the clinic. Visit notes, summaries or a named contact for referring practices.

We left out practice software and EHR vendors that also host dietitians, and medical groups that prescribe as well as counsel, because they overlap with what your clinic already does. The order is our editorial view, not a measure of results.

1. Nourish

Nourish is a telehealth company that connects patients with registered dietitians in all 50 states. It reports over 10,000 providers on its platform and lists dedicated dietitian care for patients taking GLP-1 medications.

What stands out:

• Fast start. Nourish states it reaches out within 24 hours of a referral and offers appointments within 24 hours.
• Closed-loop notes. It describes sharing notes with the referring provider as the patient goes through intake and appointments.
• Published cost. Nourish reports 94% of patients pay $0 out of pocket; the self-pay rate is $145 per session, and HSA/FSA funds are accepted (as of October 2026).
• Limits stated plainly. Medicare referrals go by fax, must come from an MD or DO and include a qualifying diagnosis (diabetes or chronic kidney disease stage 3+). Medicaid is not currently accepted.

Right for: clinics running GLP-1 or medical weight loss programs that want a fast handoff and regular updates. Ask: how notes reach your team (fax, portal or EHR), and how many of its dietitians focus on weight management in your state.

2. Fay

Fay lists 3,400+ registered dietitians across all 50 states, with sessions online or in person. Specialties include weight loss, GLP-1s, diabetes, gut health, PCOS and sports nutrition. It reports serving 100,000+ members.

What stands out:

• Two referral routes. Send patients to the Fay site to self-book, or complete a form and Fay contacts the patient for you.
• Session summaries. Fay states the referring provider receives a detailed summary after each RD session, with the patient's approval, covering topics, progress and plan changes.
• Insurance. It accepts 700+ plans, including Anthem, Blue Cross Blue Shield, UnitedHealthcare, Aetna, Cigna and UMR, with sessions "as low as $0" with insurance.

Right for: clinics that want a large bench of dietitians and the option of in-person visits. Ask: the self-pay rate (not published on the referral page) and how summaries are delivered.

3. Berry Street

Berry Street offers online one-to-one nutrition therapy with registered, board-certified dietitians. It reports 1,250+ insurance plans accepted, 200,000+ patients served, and that most patients pay $0 out of pocket.

What stands out:

• Three ways to refer. An online form, fax or e-fax, or an EHR integration (instructions by email to its referrals team).
• Post-visit summary. Berry Street states it contacts the patient by text and email within 24 hours and automatically faxes a detailed post-visit summary after the first session.
• A named contact. Practices can request a Clinical Partnerships Manager for education, marketing materials, EHR support and troubleshooting.

Right for: busy clinics that want referrals to take under a minute and a single person to call. Ask: which states it covers (not stated on the referral page) and whether you get summaries after later visits too.

4. Culina Health

Culina Health provides virtual one-to-one and group counseling with registered dietitian nutritionists in 50 states. Specialties include sustainable weight loss, a "GLP-1 Journey" program, hormone health, GI health and diabetes. It reports 2,000+ referring physicians and that about 93% of patients receive insurance coverage.

Referrals come by online form, e-fax or EMR connection. Culina states it contacts patients within 24 hours, most schedule within 7 to 10 days, and the provider receives care notes within 24 hours after each session. It also lists a provider newsletter and peer-learning events.

Right for: clinics that want regular written notes and a team used to working with physicians. Ask: which plans are in network in your state and the self-pay rate.

5. Season Health

Season Health describes itself as a food-as-medicine platform: virtual dietitian visits plus medically tailored meals and groceries delivered to the patient's home. It reports serving over 100 conditions and that 95% of its patients meet with a dietitian for free.

Providers refer through an online form, email or phone. Season states patients typically meet a dietitian within seven days. Its site does not mention GLP-1 medications specifically.

Right for: clinics whose patients struggle with what to eat day to day, not just what to aim for. Ask: how meals are paid for (insurance or out of pocket) and what updates you receive after visits.

6. Academy of Nutrition and Dietetics: Find a Nutrition Expert

The Find a Nutrition Expert directory is run by the Academy of Nutrition and Dietetics, the professional body for dietitians. It lists RDNs and NDTRs and can be searched by location, specialty, language, and insurance and payment options.

It is not a network that takes referrals. It is where you find an independent, local dietitian to partner with directly: one who can see patients in person, join a group class at your clinic, or rent a room one day a week.

Right for: clinics that want a local name and face rather than a national telehealth service. Ask the dietitian: whether they bill insurance themselves, carry their own liability coverage, and will sign a written referral or space agreement.

7. Dietitians On Demand

Dietitians On Demand is a dietitian staffing company founded in Richmond, Virginia, in 2005. It reports 500+ dietitians working more than 200,000 hours a year across acute care, long-term care, virtual and other settings. It covers vacancies, leave, temp-to-perm, direct hire and special projects.

Its site centers on hospitals and long-term care, so it is a less obvious fit for an outpatient clinic. It is on this list because it is a way to put a dietitian on your own team. It states an average of seven days to fill a position; rates vary by location, duration and hours.

Right for: larger clinics or groups that want a dietitian working inside the practice. Ask: whether it places part-time or remote dietitians with outpatient clinics, and the minimum hours.

Questions to ask any dietitian network

1. How do we refer? Form, fax, e-fax or EHR. Try one test referral before you tell patients about it.
2. What comes back to us, and when? Ask for a sample visit summary and how it reaches your team.
3. What will the patient pay? Get the self-pay rate, which plans are in network in your state, and whether Medicare or Medicaid is accepted.
4. Who are the dietitians? Confirm they are registered dietitians licensed where your patients live, and ask how many focus on weight management or GLP-1 care.
5. Will you sign a BAA? You will share patient health information with them, so ask whether they sign a business associate agreement or receive the referral under their own HIPAA treatment exception. Have your attorney confirm which applies.
6. Is anything paid either way? Referral fees or payments between a clinic and a provider that bills insurance can raise anti-kickback questions. Keep the arrangement free of payments unless your attorney approves it.

Where Prospyr fits

The network handles the nutrition visits; your clinic still owns the weight loss program, the follow-up and the patient's chart. Most networks send notes by fax or portal, so plan where those notes live. Prospyr's lab ordering and follow-up messages help keep the medical side of a program on schedule, and you can book a practice demo to see it.

Frequently asked questions

Can a medical weight loss clinic refer patients to an outside dietitian?

Yes. Every network on this list takes referrals from providers, usually by online form or fax. The patient then books directly with the network, which bills their insurance or charges a self-pay rate. Ask for visit notes so your provider sees what the dietitian recommends.

Does insurance cover dietitian visits for weight loss?

Often, but it depends on the plan. Nourish, Fay, Berry Street and Culina Health all report that most of their patients pay little or nothing with insurance. Nourish states that Medicare referrals must include a qualifying diagnosis such as diabetes or chronic kidney disease, so a weight loss goal alone may not qualify.

Should a clinic hire its own dietitian or use a network?

Use a network first if you have fewer than a few dozen active weight loss patients. None of the networks here publishes a fee for referring clinics, and they cover many insurance plans. Hiring makes more sense once you have steady volume, want in-person group classes, or want dietitian visits included in your own program price.

What is the difference between a dietitian and a nutritionist?

A registered dietitian (RD or RDN) holds a national credential; "nutritionist" is a broader title whose rules vary by state. Check your state's licensing board before you partner with anyone who is not an RD. For patients on medication, partner with registered dietitians.
