Why Generic Advice Fails & The TDG Philosophy
Before any test, protocol, or supplement — you need to understand why everything you've already tried probably hasn't worked. This is where we begin.

02
Nutrition & Behaviour
Nutrition Principles & The Psychology of Change
What your cells actually need from food, why the supplement-first approach works against you, and why knowing the right thing and actually doing it are two entirely different problems.
03
Stress & Nervous System
Stress, the Nervous System & the HPA Axis
The most underappreciated driver of chronic health problems. The science is exceptionally clear — the UK cultural script tells us to get on with it. This module explains, biochemically, why that script is killing people slowly.
04
Gut Health
Digestive Health — The Foundation of Everything
If your gut isn't working properly, nothing else will. Not your diet, not your supplements, not your hormone protocol. Why gut health is the primary system — and why guessing about it is more expensive than testing.
05
Hormones
Hormonal Balance — The Conductor of Your Symphony
Exhausted despite eight hours sleep. Weight gain despite eating well. Anxiety for no clear reason. Your hormones are trying to tell you something — and standard testing is almost certainly not listening properly.
06
Metabolism
Metabolic Health & Blood Sugar
By the time standard testing detects a blood sugar problem, you've typically been progressing through metabolic dysfunction for a decade. The problem starts with insulin, not glucose — and standard testing almost never measures insulin.
07
Immunity & Inflammation
The Immunity–Inflammation–Detox Trinity
Three systems that conventional medicine treats as separate departments are, clinically, a single integrated response sequence. Understand the connection — and why treating any one in isolation consistently underperforms.
08
Sleep & Recovery
Sleep, Circadian Health & Movement
You don't have a sleep problem. You have a light problem. Your sleep problems probably began the moment you woke up and checked your phone — and the fix is far simpler, and far more biological, than anything the sleep hygiene industry sells you.
09
The Five Tests
Understanding Your Tests — The Five-Test Programme
Eight modules of clinical context have built to this point. What we're measuring, why each test was selected, what it reveals that standard testing cannot, and how the five tests work as an integrated investigation system.
10
Biochemical Individuality
Metabolic Nature Profiling
There is no universally healthy diet. What nourishes one person depletes another. The question is never "which diet is best?" — it is always "which approach is best for you?" This module answers that question through your biochemistry.
11
Implementation
The Intervention Toolkit
The clinical framework is established. This module is where it becomes action. Diet, supplementation, gut healing, and stress management — sequenced correctly, dosed intelligently, applied to what your testing has revealed.
12
Clinical Application
Clinical Conditions
Fatigue, digestive conditions, hormonal imbalance, weight loss resistance — mapped through every system covered in this manual. What the pattern looks like, what testing reveals, and the precise sequence of intervention.
13
Protocol & The Long Game
Building Your Protocol & The Long Game
You have the test results. You understand the systems. You know the interventions. The bridge from data to action — sequencing logic, clinical decision trees, and the mindset required for the months of patient work that genuine restoration demands.
