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
Most people — even in Palm Beach — have been through the same frustrating cycle. Excellent doctors who offer limited answers for digestive issues. Weight management programs that work temporarily and then don't. Generic nutrition advice that ignores your individual physiology, your schedule, your lifestyle.
That is not what I do.
Every client I work with receives a program built entirely around them — their history, their metabolism, their food preferences, their goals. I don't offer protocols. I offer solutions.
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.

This is nutrition care at the level Palm Beach demands — a dedicated expert who is genuinely part of your wellness team.
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.
