Founder, Expert Functional Registered Dietitian and Chief Clinical Strategist.

HI, I'M LAUREN!

welcome!

I founded Functional Fueling® to be a trusted place where you can find clear answers and unwavering support on your healing journey. With a decade of experience and thousands of patients helped, my approach goes beyond standard dietary guidelines—we focus on uncovering the root causes of imbalance. By examining physiological, genetic, environmental, and biochemical factors, we use food-as-medicine to support true healing. My team and I are dedicated to providing a clear, personalized path to help you regain your energy, vitality, and the ability to fully show up for what matters most in your life. Functional nutrition and diagnostic testing are just two of the powerful tools we use to guide your transformation. I’m so grateful you’re here!

"I want you to know what a tremendous impact you have made in my life in just the past few months. Thank you for empowering me and guiding me towards a healthier future. Choosing you as my dietician was one of the best decisions I've ever made."

"Lauren has changed my life. For about 7-8 years I had really horrendous symptoms like zero energy, super irregular bowel movements, struggled to lose weight, just really quite miserable. Since working with her, I haven't had a tummy ache, have lost 24 lbs., my skin is amazing, I have so much energy."

"I began working with Lauren/FFN after battling severe PCOS symptoms. I had unexplained weight gain, had never had a regular period in my life, horrible acne, constant/chronic fatigue. I now have a regular period, reduced so many of my symptoms, and I've lost over 50 lbs since I started working with FFN "
