Who is Sarah?

Your body, your goals, your plan.

Hi, I’m Sarah Polk, founder and registered dietitian at Sarah Polk Nutrition, LLC, based in Saint Louis, Missouri.
In 2025, after years of helping individuals navigate the complexities of weight management, I knew it was time to take a leap and create something of my own. I wasn’t exactly “ready” in the traditional sense—I didn’t have a set plan for running a private practice—but I was passionate about offering a personalized, science-backed approach to weight loss that truly focuses on the individual.

And I’m so glad I trusted my instincts.

What started as a vision for Sarah Polk Nutrition quickly became a practice dedicated to helping people make sense of their unique biology and discover a weight loss plan that works for them. Whether it’s through tailored nutrition plans or the exciting field of nutrigenomics, my focus is on providing clarity, guidance, and personalized care in a world full of conflicting advice.

With a Master of Science in Nutrition & Dietetics from the University of Kansas Medical Center, and years of experience working in weight management and personalized nutrition, I’m here to help you make lasting, informed decisions about your health. I specialize in creating customized strategies—no one-size-fits-all solutions here.

I don’t believe in quick fixes or generic advice. My approach is all about compassion, sustainability, and helping you build a realistic plan that’s as unique as you are. Together, we’ll find what works for your body, your goals, and your life.
