Jillian Acosta

Registered Dietitian, Owner of The Root Cause Method

Jillian Acosta is a registered dietitian and owner of the functional nutrition private practice, The Root Cause Method. In her practice she works with clients to uproot life-long behavioral patterns and deeply buried traumas that result in physiological imbalances. Through her expertise in functional nutrition, she provides personalized dietary guidance to support the body, but Jillian takes her clients beyond the physiology to address the underlying psychological and emotional reasons that drove each client to their current state of health. Her work results in measurable and lasting changes, that dramatically improve her clients’ relationships to food, their bodies, and themselves.  Uncovering and uprooting what shapes our relationship with food is, in her experience, what’s missing in the reversal and prevention of obesity and associated chronic illnesses, and what’s standing in the way of true embodiment, fulfillment and connection.


Jillian earned a Bachelor of Science degree in Dietetics and Nutrition where she graduated Magna Cum Laude from Florida International University. She has received extensive training from the Institute for Functional Medicine through the University of Western States. She lives in Delray with her dog, Daisy.
