A Place to Start
— Written Down, Then Checked

Most dietary advice is written for the average person. Metabolic Natures gives you a starting point instead: a reading on two axes from a questionnaire about how you have always run, built into a food guide, menu plan and recipes worked out for your plate, then adapted to how you cook and what you like at follow-up — with what should change written down before you begin, and checked when you return.

Not everyone thrives on the same diet

The six names describe positions on two axes — oxidative rate and autonomic balance — and you are given a position on each rather than one label out of six. They come from a structured questionnaire about how you have always been, not from a laboratory test. Nothing measures constitution, and the questionnaire does not either: it is the starting hypothesis. Functional testing answers a different and more immediate question — what your biochemistry is doing now — and where the two disagree, current function governs the protocol until the constraint clears.

What the axes are meant to capture is a real observation: people respond very differently to the same food, and a high-fat, high-protein approach that suits one person can leave another flat. Whether a questionnaire position predicts which way a given person will go is not established. The point of the framework is to decide which direction to start in, and then to write down what we expect to change before we begin.

Axis 1 · Oxidative — sets the macronutrient framework
Endurance
Slow · more starch, less fat
Adaptive
Mixed · the middle · balanced plate
Catalyst
Fast · less starch, more fat
Axis 2 · Autonomic — adjusts carbohydrate within it, never sets it
Grounded
Parasympathetic · carbohydrate a little lower
Calibrated
Balanced · no adjustment
Kinetic
Sympathetic · carbohydrate a little higher

You get a direction and a strength on each axis, oxidative first — so a reading is oxidative: fast, lean 72%, strength 64% · autonomic: parasympathetic, lean 68%, strength 41% — low strength, with Catalyst · Grounded (low) as shorthand. Protein is not on this axis: it is set by your body weight and is the same on every plate. The autonomic adjustment is small — about two tablespoons of cooked rice a meal, and only when the reading is strong (50% or more) — and an interim position. Meal timing follows your own answers, not the label. See both axes on one page · These cards previously assigned the six names to the wrong axes — the correction is here.

What this is, and what the evidence for it actually is

Metabolic Natures is a framework for deciding where to start, not a test result.

What is well supported: people respond very differently to the same meal. One study tracked 800 people across nearly 47,000 meals and found high variability in blood glucose after identical meals DOI; another, of 1,002 UK adults, found the same for glucose, insulin and blood fats — several of its authors work for a commercial nutrition company, which we note as we would for any study DOI.

What is not established: that any one person does better long-term on one particular balance of food. When four named diets were compared for a year, weight loss tracked how well people stuck to the plan (r = 0.60) and essentially not at all which plan it was (r = 0.07, not significant). DOI The balance you can actually sustain is the one that works.

The specific categories are not validated by controlled trials, and we do not claim they are. No trial has tested whether assigning someone to an oxidative or autonomic category, and matching a macronutrient ratio to it, produces a better result. The closest test of that shape of argument is DIETFITS — 609 adults, healthy low-fat against healthy low-carbohydrate, twelve months, a difference of 0.7 kg between arms, and neither a genotype pattern nor baseline insulin secretion predicted which diet suited whom. DOI DIETFITS did not test oxidation rate or autonomic tone, so it is not a direct refutation — but it tested the logic, and the logic did not hold up.

So what are we claiming? That a structured way of recognising your own long-standing pattern, adjusted from what your test findings currently show, gives you an approach you can recognise yourself in and therefore sustain. And one thing more, which is the part that can be wrong: we write down, before your protocol starts, what we expect to change and by when — and we check it at retest. That prediction can come back not met. Nothing else in the framework can.

And what we are not selling. Metabolic Natures recommends no proprietary formula, and no product is required for the method to work. The lineage this framework comes from did the opposite — it defined its own efficacy as depending on a sole-source supplement range. That is named here because the same standard has to apply to a tradition we came from as to one we did not.

What used to take 12 sessions — restructured

In traditional nutritional therapy, ongoing dietary support meant a series of weekly or fortnightly sessions at £60–95 each — £360–1,140 over a programme — because the contact time was the only way to handle the ongoing questions, menu adaptations, and accountability that make dietary change stick. Every "what do I do with this ingredient?" and "I'm travelling next week — what do I eat?" required a session.

The DH Clinical Concierge changes that entirely. The ongoing questions that used to require session time are now handled between sessions through the concierge — which knows your reading, your plate, your allowable foods, your dietary framework, and your goals. The formal sessions focus on what only a practitioner can do: the clinical assessment, the protocol decision, and the review of what's working.

Between-session support that used to cost a session

The most common reason dietary change fails is not lack of information — it is lack of support at the moment when the question arises. You're in a supermarket and unsure whether something is on your list. You're travelling and need a fast option that fits your plan. You want to adapt a recipe. You've been on the plan for three weeks and your energy is different on certain days and you want to know why.

The DH Client Concierge is available to answer all of these in real time — configured with your reading, your plate, your allowable foods, your dietary framework, and your goals. It is not a generic nutrition chatbot. It is a clinically-guided tool built with your specific picture in mind.

What the concierge handles between sessions
Menu modifications — "I don't like fish, what replaces the salmon in this meal?"
Travel adaptations — "I'm in an airport for four hours, what fits my plan?"
Quick meal ideas — "I have 15 minutes and eggs, spinach and avocado — what fits my plan?"
Smoothie and soup variants — quick, practical options when you need something fast
Label reading — "Is this ingredient on my allowable list?"
Understanding your plan — "Why does my energy drop in the afternoon, and is that worth flagging?"
Progress questions — "I've been on the plan for three weeks, my sleep is better but my energy is still variable — what might explain that?"
Anything worth flagging for your follow-up consultation with Stephen

From intake to ongoing support

1
Free 20-minute call (optional)
If you're not sure whether the programme is right for you, or whether you should be doing this before or after functional testing, a free 20-minute call clarifies the right sequence. If you're ready to proceed, start the programme and go straight to step 2.
2
Metabolic Nature intake form
Once confirmed, you receive the Metabolic Nature intake form. This covers your energy patterns, macronutrient responses, stress physiology, sleep quality, digestive tendencies, and food preferences — the picture that gives your starting reading. Takes approximately 20 minutes to complete.
3
Your reading and plan preparation
Stephen reviews your intake form and reads your direction and strength on each axis. Your food guide, menu plan and recipe library are then worked out for the plate that reading points to, with your protein set from your body weight and any exclusions you've noted taken out. At your follow-up we adapt them further to how you cook, what you like and how your weeks actually run.
4
Programme consultation — 60 minutes
Your reading, what it rests on, your foods list and your menu plan are explained in detail. Before you start, what we expect to change and by when is written down, so it can be checked. You receive Volume 1 of the revised Metabolic Natures book when it is complete, and access to AIdan, your client concierge. Implementation begins.
5
Concierge support — ongoing
Between the programme consultation and your follow-up, the DH Client Concierge is available for menu modifications, recipe ideas, travel adaptations, ingredient questions, and anything that arises in day-to-day implementation. This is the support layer that makes the difference between knowing what to eat and actually eating that way.
6
Follow-up review — 30 minutes at 4–6 weeks
A formal review against what was written down at the start: what changed, what didn't, and what needs adjusting. If the expected change has not happened and nothing was in the way, that counts against the reading, and it is reconsidered rather than explained away. Any questions the concierge has flagged for clinical input. Plan refinements. Assessment of whether functional testing would add value at this point — and if so, which tests and in what sequence.

Metabolic Natures — the reference behind the programme

Metabolic Natures — Test, Don't Guess Volume 4

The second edition is being rewritten to the current method. Programme clients receive Volume 1 when it is complete. Note that all printed editions describe what the questionnaire and the tests measure the wrong way round. The dated correction lists the seven places by page.

Included in the programme: Volume 1 of the revised second edition, delivered when complete.

Included in programme

Standalone or as part of a bigger programme

The Metabolic Natures Programme works as a standalone service for people who want to improve their diet without committing to full functional testing yet. It is also included as an add-on within the TDG Five-Test Programme and the Three-Test Gut and Cellular Health Package — where the test results show what is currently in the way, and govern the plan until it clears.

If you complete the Metabolic Natures Programme and then go on to functional testing, the tests do not change your reading — no test identifies a position. What they add is whatever is currently in the way: where they find it, it takes priority in the plan until it clears, and your reading is looked at again after that.
