What are the four fixes, and does the order matter?

Yes, the order matters. They are listed in the sequence that produces the least friction: the first one is usually the constraint everything else is waiting on, and starting at number three while number one is still broken is why previous attempts stalled. Run them in order, give each one long enough to actually take hold, and resist the urge to add a fifth. The shortest list you will still be following in three months beats the complete one you abandon in two weeks.

How long before I see anything change?

Different markers move on different clocks, and knowing the order in advance is most of what stops people quitting in week three. Subjective things — sleep, energy, appetite stability — usually shift first. Strength follows. Waist and bloodwork are slower and considerably more informative. We do not publish weight-loss figures or timelines, because honest ones do not exist for an individual. What the research does show consistently is that adherence predicts the outcome better than which framework you picked.

Do I need blood work before I start?

You can start the structural parts — sleep window, protein floor, resistance training, reducing ultra-processed food — without any test at all. None of them require a diagnosis to be sensible. Bloodwork earns its place when it changes what you should do, or when a marker needs watching while you change your diet. If any of the items on the right apply to you, get the labs first and involve a clinician.

Can I run this while I am on medication?

Usually, but not unsupervised. Dietary change alters how much medication some conditions need — glucose-lowering drugs in particular — and that adjustment belongs with the person who prescribed them. Tell your prescriber what you are changing and when. It is a two-minute conversation that prevents the one genuinely risky failure mode in an otherwise low-risk protocol.

What happens if I miss days?

Nothing structural. This is a protocol, not a streak — the physiology responds to what you do most weeks, not to an unbroken chain of perfect ones. Missing a training session or a bedtime does not reset anything. The pattern to watch is not the missed day but the missed fortnight. If one of the four fixes keeps sliding, that usually means it was too big a change to start with, so shrink it until it is boringly achievable and rebuild from there.

How is this different from the paid programme?

The research is identical and none of it is held back. What the free protocol cannot do is sequence twelve weeks for you, read your bloodwork, or notice that your logs stopped matching your plan three weeks ago. Most people should run the free protocol first. If it holds and you want structure and human review on top of it, the programme is there — and if the free version is working on its own, we would rather you kept your money.

01The mechanism

What is actually happening

Repeat dieting produces measurable, persistent metabolic adaptation — your resting metabolic rate is now meaningfully below what calculators predict. The Fothergill 2016 Biggest Loser study documented that contestants' RMR remained ~500 kcal/day below predicted six years after the show, even as most regained weight. Rosenbaum & Leibel's foundational reviews quantify this 'adaptive thermogenesis' as a 5–15% reduction in expenditure beyond what mass change alone would explain — driven by leptin drop, sympathetic-nervous suppression, lower thyroid output, and more efficient skeletal muscle. The implication: any new calorie target you set will overshoot, you'll plateau, and you'll feel like 'nothing works'. The path forward isn't another deficit — it's a recovery period at maintenance with strength training and protein optimization, then a more modest deficit (10–15% rather than 20–25%) executed slowly.¹²³⁴⁵

Who this fits

Repeat dieting produces measurable, persistent metabolic adaptation. Generic calorie targets undershoot for you. Approach this differently than first-timers.

Evidence base

This protocol rests on 5 peer-reviewed sources, listed in full further down the page. Where the evidence is mechanistic rather than outcome-based, the text says so.

02Highest leverage first

The four things to fix first

In this order. The first one is usually the constraint everything else is waiting on — starting at number three while number one is still broken is how previous attempts stalled.

01
Eat at maintenance for 8–12 weeks first
Counterintuitive but critical. Hormonal recovery (leptin, thyroid, sympathetic tone) requires time at maintenance before another deficit can work. Use the TDEE calculator with the diet-history correction.
02
Build muscle before cutting again
Strength training during the maintenance period rebuilds metabolic capacity. Each kg of muscle added is more glucose-disposal capacity and slightly higher RMR — Bray 2012 showed lean mass gain at maintenance protein intake.
03
When you eventually deficit, do it small and slow
10–15% deficit, not 20–25%. 0.5% body weight loss per week, not 1%. Slow loss preserves more lean mass and produces less adaptation than aggressive cuts.
04
No more 12-week 'sprints'
Pick a sustainable framework you can run for 24 months and run it. Mediterranean, paleo, low-UPF whole foods — anything you can sustain. The framework matters less than the duration.

What to track

Evidence about your own body

01Strength progression in primary lifts

03Weight (weekly average for 12 weeks before deficit)
04Sleep hours nightly

Eight weeks of this gives you data about you, rather than an average from a study population.

04Where to go next

When to consider the full programme

This gets you from zero to functional

The starter protocol is designed to be self-run for two to four weeks. If you want the structured twelve-week curriculum — daily sequencing, meal guidance, lab interpretation by a clinician and a mentor who reads your logs — that is what the Ancestral Reset is.

Questions people ask first

Multiple cycles. Your TDEE calculator is lying to you. If that sentence describes the last year or two of your life more accurately than it describes anyone else's, you are in the right protocol.

Archetypes overlap on purpose — most people recognise themselves in two or three. The assessment resolves that by weighing the whole combination of your answers rather than one keyword, and tells you which pattern to work on first.
