Fuelling Your Body for Optimal Health: The Ultimate Guide to Functional Nutrition

Updated: May 9

Let’s start with the important question. What is Functional Nutrition?

In short, Functional Nutrition is the science of applied biochemistry. It is a proactive and preventive approach to health that delves beyond surface-level remedies to uncover the root cause of ailments. Rather than simply masking symptoms, it addresses the imbalances within the body contributing to a person’s symptom(s) or illness.

In contrast to traditional healthcare, which often treats individual symptoms separately, Functional Nutrition seeks to understand if these symptoms might be linked to a common root cause. By nourishing the body at the cellular level, Functional Nutrition addresses this root cause effectively by utilising the healing properties of food and lifestyle modalities to rebuild and repair the body’s biochemical and metabolic processes.

Functional Nutrition practitioners take a holistic approach to diet and wellness, assessing the entire body and evaluating different imbalances that may be present. These imbalances can involve factors such as chronic inflammation, various toxicities, nutrient deficiencies, environmental exposures, stress levels, digestive problems, microbial imbalances, activity levels, and hormone imbalances, all of which can contribute to chronic diseases such as arthritis, obesity, cancer, diabetes, heart disease, and autoimmune disorders.

In the realm of Functional Nutrition, health is not merely the absence of disease; it is a state of vibrant well-being and vitality. Recognising that each person possesses a unique physiological makeup and follows distinct dietary and lifestyle patterns, Functional Nutrition shuns the one-size-fits-all approach to treatment. Just because two individuals have the same disease does not mean that a uniform solution will suit both. This allows healthcare professionals to create an individualised plan that promotes whole-body health and wellness.

The principles of Functional Nutrition encompass the following:

Holistic Perspective: Functional Nutrition considers a person’s environment, genetics, and lifestyle as crucial factors when designing Nutrition and lifestyle-based solutions.

Continuum of Health: It views health and disease as existing on a spectrum rather than being distinct entities and aims to optimise health across this continuum.

Root Cause Connection: Functional Nutrition connects imbalances within body systems with the root causes of diseases, focusing on resolving those core issues.

Integrative Approach: It is an integral part of Functional Medicine to work with other healthcare practices to provide comprehensive and personalised care.

By adhering to these principles, Functional Nutrition and Functional Medicine offer a comprehensive and personalised approach to health and well-being.

As a Functional Nutritionist, my role revolves around a distinct scope of practice. I refrain from diagnosing, prescribing, or treating specific medical conditions. Instead, my focus lies in a holistic approach aimed at:

Understanding the Whole Person: I deeply value comprehending each individual as a unique entity, considering their physical, emotional, and lifestyle aspects. This comprehensive understanding helps me tailor my approach to their specific needs.

Addressing the Terrain: Rather than solely addressing the visible signs, symptoms, or diagnosis, I delve deeper into the underlying terrain within the body. By exploring the root causes and imbalances that contribute to health challenges, I strive to offer a more sustainable and effective solution.

Empowering Through Education: Education forms a core aspect of my practice. I believe that empowering clients with knowledge about the origins of their health challenges and providing them with the tools to regain control over their well-being is paramount to achieving long-term results.

Through this multifaceted approach, I aim to empower individuals to take charge of their health and achieve optimal wellness and lasting transformation through the power of correct nutrition and a healthy lifestyle.

I sought Marie’s help for a specific health-related goal – how to avoid surgery to remove my gallbladder (hormonal connection). Marie offered me an in-depth tailor-made dietary and lifestyle plan. By sticking to it, I’m delighted to say I haven’t suffered any further debilitating Gallstone attacks.


Marie is very knowledgeable with a caring approach and I highly recommend her.
