Malibu Dietitian
IBS, SIBO & Weight Management

In Malibu, your standards are high across every area of your life. Your nutrition care should be no exception.

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. Based in Beverly Hills and serving Malibu clients virtually, I offer the kind of specialized, personalized care that simply isn't available from a generalist.

The Level of Care You Deserve

Most people — even in Malibu — have been through the same frustrating cycle. Excellent doctors who offer limited answers for chronic digestive issues. Weight loss programs that produce short-term results and long-term disappointment. Nutrition advice that ignores the complexity of your individual physiology, lifestyle, and goals.

That ends here.

Every client I work with receives a program built entirely around them. Not a template. Not a protocol. A genuinely personalized strategy developed from a deep understanding of your history, your metabolism, your food preferences, and your life.

Specialized Expertise That Gets Results

Irritable Bowel Syndrome (IBS) and Small Intestinal Bacterial Overgrowth (SIBO) are among the most misunderstood and mismanaged conditions in modern medicine. The majority of people suffering with chronic bloating, digestive pain, and unpredictable symptoms have never been properly tested or treated.

I am Monash University certified in the low-FODMAP diet — the gold standard for IBS and SIBO treatment — and have been working in this specialty since before most practitioners knew what SIBO was. My personal experience navigating this condition, including being among the first patients to complete a SIBO breath test through Dr. Mark Pimentel's research at Cedars-Sinai, gives me a depth of understanding that clinical training alone cannot provide.

For weight management, my approach addresses the root causes that have made previous efforts unsuccessful — hormonal changes, metabolic adaptation, lifestyle patterns, and underlying gut dysfunction — with a clear, structured strategy designed for permanent results.

The VIP Program

For clients who want the highest level of access and personalization, my VIP program offers:

  • Unlimited direct text access — reach me as questions arise
  • Daily check-ins and ongoing feedback
  • Fully customized meal planning based on your preferences and goals
  • Bi-weekly personalized grocery lists
  • Coordination with your personal chef locally or internationally
  • Restaurant guidance tailored to your regular dining habits
  • Full access to my secure client platform for tracking, menus, and nutrition analysis
  • Ongoing adjustments based on your progress

This is nutrition care without compromise — a dedicated specialist who is fully invested in your results.

Serving Malibu's Most Discerning Clients

My clients include executives, artists, entrepreneurs, and individuals who have the means to access the best and the discernment to recognize it. They come to me after seeing top specialists and still not having answers. They leave with a clear plan, measurable results, and the tools to sustain them for life.

All sessions are conducted virtually — seamlessly integrated into your schedule, accessible from your home, your office, or anywhere in the world. The same level of care you'd expect from a world-class specialist, without the inconvenience of travel.

My expertise has been featured in many major media outlets including Forbes, Martha Stewart Living, Prevention, and more. I am the author of two books — The Beginner's Guide to Low FODMAP and Fill Your Plate, Lose the Weight.
