Specialist Nutritional Therapy & Lifestyle Medicine Practice.
Providing evidence-based nutrition and lifestyle strategies tailored to your unique physiology. Whether you need specialist support for a chronic condition or want to prevent disease and age more healthfully, we use a systems-based approach to identify root causes and restore — or enhance — your health and vitality.
The Eglin Methodology: More Than Just Diet.
Our holistic health programmes extend far beyond simple dietary changes. To achieve genuine, sustainable recovery and lasting wellness, we utilise a structured framework that addresses the complex internal and external drivers of health. Every programme is built upon three core components:
The 4 Key Systems: A rigorous functional analysis of the body’s primary regulatory networks - Digestive, Immune, Endocrine, and Nervous - to resolve the root causes of dysfunction.
The 6 Pillars of Health: The integration of essential, evidence-based lifestyle factors tailored to support long-term wellness.
Client Empowerment: The strategic use of education and science-driven coaching to equip you with the tools needed to take full control of your health.
