Hi, I’m Lauren, but you can call me “Lo.” 

I’m an integrative registered dietitian passionate about helping you reclaim your health so that you can thrive from within.

I am a firm believer that the food we eat and root cause treatment can truly change our life. I’ve seen it firsthand in my own life and in helping thousands of patients.

My philosophy is built on 5 things:

1. Get to the root cause
2. Use real, nourishing food
3. Base recommendations on preciseness and optimal, not “average”
4. Treat you as a whole person
5. Contribute to improving your quality of life

• Master’s Degree in Nutritional Sciences; Integrative Nutrition
• Registered Dietitian Nutritionist through the Commission on Dietetic Registration
• Certified Specialist in Sports Dietetics through the Commission on Dietetic Registration

(yes, I love learning!)

Lauren Papanos Bio:

Lauren Papanos is a highly experienced integrative registered dietitian and the owner of Functional Fueling Nutrition. Lauren is committed to helping patients use food and lifestyle as medicine for management of endocrine conditions and symptoms.

During her graduate studies and Dietetic Internship, Lauren had the opportunity through didactic education and mentorship to learn and implement functional nutrition. Following her Dietetic Internship she went on to complete a highly regarded sports nutrition fellowship. Through both of these experiences she was able to learn how to seamlessly integrate functional nutrition principles in many different conventional settings: acute care, outpatient and sports nutrition.

In 2016, Lauren established Functional Fueling Nutrition, a virtual nutrition practice that offers lab testing, individualized nutrition and supplement protocols for patient care. In 2021, Lauren created the brand, Strength in Hormones, a podcast, collective membership and hybrid program for women of all ages to overcome nutrition and lifestyle related hormone symptoms. 

Lauren strives to empower her patients to see food and lifestyle as the vehicle to healing and lifelong wellness. To take women from frustrated to high functioning and provide them with the clarity and education they deserve in order to live their healthiest, hormone-balanced lives.
