Fay Nutrition Review 2026: The Missing Piece of Your GLP-1 Program
Fay Nutrition is not a GLP-1 prescriber. It is a dietitian matching platform that connects you with registered dietitians who specialize in GLP-1 support, and most sessions cost $0-$10 with insurance. With 2,500+ RDs across all 50 states, 700+ insurance plans accepted, and $75M in venture funding (Goldman Sachs led the Series B), Fay fills a gap that most telehealth GLP-1 platforms ignore: what you eat while on the medication.

Pricing
| Item | Cost |
|---|---|
| With insurance | $0-$10/session |
| Without insurance | $100-$250/session |
| Initial consultation | 60 minutes |
| Follow-up sessions | 30 minutes |
The value proposition is simple: if you have insurance, Fay handles the billing and you pay close to nothing for professional nutrition counseling. They offer a price guarantee where they honor the estimate from their eligibility tool, with a refund if the actual cost differs.
Without insurance, the $100-$250 per session price makes this hard to justify. The entire model hinges on insurance coverage.

What I Like
Insurance Covers Almost Everything
This is why Fay exists. Most GLP-1 platforms charge $149-$399/month and none of it goes through insurance. Fay flips that: your insurance handles the dietitian cost, and you pay a copay that is usually under $10. If you are already spending $200+/month on a GLP-1 program, adding $0-$10 dietitian visits is a no-brainer.
GLP-1-Specific Dietitians
Not generic nutrition advice. Fay matches you with RDs who specialize in GLP-1 support: managing nausea, preventing muscle loss, hitting protein targets on a suppressed appetite, navigating plateaus, and building eating patterns that stick after you taper off medication. In the STEP 1 extension trial, participants who stopped semaglutide regained two-thirds of their lost weight within a year (NEJM, 2022). Nutrition coaching during treatment is one of the best defenses against that rebound.
Largest Dietitian Network in the US
2,500+ registered dietitians across all 50 states. Virtual and in-person options. You are not limited to whoever happens to be available. You can filter by specialty, language, and location.
The App Adds Value Between Visits
Messaging with your dietitian, meal planning tools, and food journals between sessions. This keeps you accountable without scheduling extra appointments.
What Could Be Better
Useless Without Insurance
At $100-$250/session without insurance, Fay is not viable for cash-pay patients. The entire model depends on your insurer being in their network. If your plan is not accepted, there is no affordable fallback.
Billing Complaints
BBB complaints mention insurance coding issues leading to unexpected charges, and some users report charges after stopping service. Fay has a price guarantee to address this, but the complaints exist. Their Illinois BBB profile is accredited. Their Ohio profile has an F rating with unresolved complaints.
Quality Depends on the Individual Dietitian
Fay is a marketplace. Your experience depends entirely on the RD you get matched with. Some users report excellent, personalized care. Others describe generic meal plans and disengaged dietitians. If your first match is not great, switch.
Not a GLP-1 Prescriber
Fay dietitians cannot prescribe medication. You still need a separate provider for your GLP-1. Fay works alongside your prescriber, not as a replacement. For GLP-1 prescribing, see our provider directory.
Who Fay Is Best For
Fay works well if you:
- Are already on a GLP-1 and want professional nutrition support
- Have insurance that covers dietitian visits
- Want help with muscle preservation, protein targets, and meal planning on GLP-1s
- Are concerned about weight regain after stopping medication
- Want a low-cost add-on to your existing GLP-1 program
