Joyce is your doctor-prescribed food companion.

Real dietitians turning your doctor's orders into "what's for dinner?"

1

Your doctor prescribes Joyce

It starts with your doctor. They prescribe Joyce and send over your medical details, then we reach out to get you started — so your care is grounded in real clinical guidance from day one, with your doctor in the loop the whole way.

2

Meet your dietitian

You meet your registered dietitian over telehealth. They get to know you — the foods you love, how you live, what feels doable — and turn your doctor's notes into your JoyceRx: a personalized plan with clinical and culinary goals over 12 sessions.

3

Text your food coach anytime

Between visits, your food coach is a text away: meal photos, pantry pics, tough questions, all welcome. Plus small, doable nudges — like finding a no-sugar dressing or trying flaxseed in your oatmeal.

4

Check in every two weeks

Join an easy 30-minute telehealth follow-up with your dietitian to review progress and adjust the plan, so it stays delicious and doable.

Nutrition care that works for everyone at the table.

We know people need to eat healthier. But no one tells them what that looks like.



There’s nothing connecting doctor’s guidance to what’s for dinner.  And those generic pamphlets definitely don’t count.

It’s an all-you-can-eat confusion buffet.

Are eggs in or out? 

Butter—yes or no? 

What about fiber? 

Protein? Gluten?

The answers aren’t on TikTok or ChatGPT. Patients deserve evidence-based support from registered dietitians.

We meet
patients
inside the loud and
messy world of‎‎ nutrition.

We give personalized answers for real life. Like real time advice from the grocery store’s produce section. Or gentle nudges that keep patients moving toward their goals.

No complicated apps. 

No fussy recipes. No insurance back-and-forths.

Person cooking eggs

Just a side of greens here. 

A dash of cayenne there. An invitation to try something new. Whether it’s a mango, a marinade, or a mixing bowl, small steps add up.

And goals turn into reality.

Eating healthier is a journey.
Meet your new companion.
