Clients benefit from a methodology that is both scientifically grounded and meticulously applied.

The Eglin Methodology: Finding The Root Cause

Eglin Health operates on the principle that the body is an interconnected system. We do not focus solely on symptoms; we investigate and assess the underlying factors that contribute to imbalance, ensuring lasting, profound results for the client. Our comprehensive methodology is built around two key frameworks:

1) The 4 Key Systems: Our Investigative Framework

Every programme begins with a rigorous functional analysis of these four major regulatory networks. We examine the complex interplay between them to identify the precise area of root cause dysfunction:

  • The Digestive System

    The Nutrient Engine & Microbiome Balance.

  • The Immune System

    Inflammation Management & Defense Network.

  • The Nervous System

    Stress Response & Mind-Body Communication.

  • The Endocrine System

    Master Regulator of Metabolism and Mood.

2) The 6 Pillars of Health: The Foundation of Every Programme

Our clinical strategy is implemented through personalised lifestyle changes built from the ground up, utilising these six accessible and foundational lifestyle pillars:

  • Basket of colourful fruit including kiwi, grapes, mango and pineapple.

    Optimal Nutrition

    Appropriate and sufficient nutrient-dense whole foods.

  • A man exercising by deadlifting a heavily weighted barbell in the gym..
