Palm Beach County
Palm Beach Dietitian
IBS, SIBO & Weight Management
In Palm Beach, you have access to the best of everything. Your nutrition care should be no different.
I'm Sarah Mirkin RDN, CPT, LD — a Registered Dietitian Nutritionist with over 25 years of clinical experience and a national reputation in IBS, SIBO, and sustainable weight management. I work with a select number of clients at the highest level of personalized care, delivered virtually so your program fits your life — not the other way around.
The Standard You Should Expect
Palm Beach runs on a social calendar, and almost none of it happens at home. Charity dinners, club luncheons, season after season of restaurant meals you didn't cook and can't control. My clients here aren't careless eaters. Most of them are the most disciplined people in the room. They're bloated anyway, and nobody can tell them why.
Here's the issue: when you eat most of your meals out, you lose visibility into the exact ingredients that trigger your gut. That's not a willpower problem, it's an information problem. My job is to give you the information back. We identify your specific triggers, then I teach you how to order anywhere on the island without thinking twice.
Most of my Palm Beach clients work with me virtually, which fits a season that never slows down. And when you'd rather sit across from me, my office at 300 S Australian Ave in downtown West Palm Beach is minutes away.
Specialized Expertise That's Genuinely Rare
IBS and SIBO are among the most mismanaged conditions in medicine. Up to 80% of people diagnosed with IBS actually have SIBO — small intestinal bacterial overgrowth — a condition that is testable, treatable, and responds exceptionally well to the right dietary approach. Most physicians are not up to date on this. Most dietitians are not trained in it.
I am Monash University certified in the low-FODMAP diet, the gold standard for IBS and SIBO treatment. I have personally navigated SIBO — I was among the first patients to complete a breath test through Dr. Mark Pimentel's research at Cedars-Sinai. I bring both clinical mastery and lived experience to every client relationship.
For weight management, my approach addresses the root causes that have made previous efforts unsuccessful — hormonal shifts, metabolic adaptation, gut dysfunction, lifestyle patterns — with a structured, evidence-based strategy designed for permanent results.

Serving Palm Beach's Most Discerning Clients
My clients include executives, physicians, entrepreneurs, and individuals who simply refuse to accept that their digestive issues or weight concerns are unsolvable. They come to me after seeing the best specialists and still not having answers. They leave with a clear plan, real results, and the knowledge to sustain them.
I work with clients on Palm Beach island, Palm Beach Gardens, Jupiter, Manalapan, and across Palm Beach County — all via telehealth, with the same seamless experience you'd expect from any world-class specialist.
My work has been featured in Forbes, Prevention, Self, Martha Stewart Living, Real Simple, Women's Health, and Everyday Health. I am the author of two books — The Beginner's Guide to Low FODMAP and Fill Your Plate, Lose the Weight.
