Who is Sarah?

Hi, I’m Sarah Polk, founder and registered dietitian at Sarah Polk Nutrition, LLC, based in Saint Louis, Missouri.
My passion for nutrition began in 8th grade during a career research project. At that time, my older sister was preparing to enter college and briefly considered becoming a dietitian. While she pursued degrees in English and psychology, I was drawn to nutrition because it's a field I could apply to my own life and others'. After all, everyone eats, and I believed nutrition would be the perfect fit.

I earned my B.S. in Nutrition and Dietetics from Missouri State University and completed my dietetic internship and M.S. in Nutrition and Dietetics at the University of Kansas Medical Center. After graduate school, I knew I wanted to specialize and found an opportunity in Saint Louis as a bariatric dietitian. Since then, I've worked in two different bariatric clinics with two separate surgeons, assisting patients with both surgical and non-surgical weight loss options, including GLP-1 therapies.

Earlier this year, after years of guiding individuals through the complexities of weight management, I felt a strong calling to create something of my own. I love working with this population and witnessing their life-changing transformations firsthand. I understand that weight loss is complex and often frustrating. By the time clients reach me, they've typically exhausted many resources. That's why I've dedicated myself to developing customized strategies—no one-size-fits-all solutions. I don't believe in quick fixes or generic advice. Our approach is rooted in compassion, sustainability, and helping individuals build realistic plans that align with their bodies, goals, and lifestyles.

To further personalize care, I've introduced nutrigenomic testing, allowing clients to understand how their genes influence their metabolism and weight loss. Starting my own practice hasn't been easy, but it has been incredibly rewarding. My focus is on providing clarity, guidance, and personalized care in a world full of conflicting advice. I'm here to help individuals make lasting, informed decisions about their health, and together, we'll find what works best for them.
