What is the difference between a nutritionist and a functional nutrition practitioner?
TL;DR: A functional nutrition practitioner uses a personalized, root-cause approach to health, treating each client as a unique biological system rather than applying a one-size-fits-all formula. While standard nutrition often focuses on calorie counting or general dietary guidelines, functional nutrition investigates the 'terrain' of the body to dismantle dysfunction and restore balance.
The Root-Cause Approach
In functional nutrition, we do not simply match a diet to a symptom. As Andrea Nakayama teaches, "This is not about a formula. Each client or patient is like a new language. I'm going to teach you how to be an interpreter." A functional approach asks why a symptom is occurring, tracing it upstream to its biological origin.
Bioindividuality over Formulas
What heals one person may inflame another. Functional nutrition relies on the principle of bioindividuality. Diet isn't static, and it will shift to meet changing physiological needs. The goal is to move from deficiency to sufficiency, establishing non-negotiables that support your unique terrain.
How Yoga and Nutrition Intersect
The gut-brain connection is central to this integrated approach. When we soften the belly and calm the nervous system through breath and therapeutic yoga, we create the internal conditions for the body to actually receive and absorb nourishment. The body cannot properly digest under chronic stress — which is why yoga and functional nutrition must work together.
They go hand in hand — especially with chronic conditions where there is often inflammation. If we can calm the inflammation, we can make everything feel better with the yoga. I address the physical pain and disturbance from a yogic perspective — choosing asana to address the pattern — and then we discuss dietary and lifestyle adjustments that may be supportive.
Frequently Asked Questions
Do you use specific diets?
When it comes to a healing diet, there's no one-size-fits-all approach. We may use elimination diets, Low FODMAP, or other therapeutic protocols temporarily to identify triggers and reduce inflammation, but the goal is always to return to the broadest, most nutrient-dense diet your body can tolerate.
