Most diets address what you eat. The NKFB method addresses what your metabolism is doing — and why it is doing it. The distinction matters because you can eat the right foods and still not lose weight if the underlying hormonal environment is working against you.
This page explains the method. The blog goes deeper on the science behind each part of it.
Leptin is the hormone your fat cells produce to tell your brain how much energy you have in storage. When everything is working correctly, adequate leptin signals the brain to reduce appetite and allow fat burning. When leptin resistance develops — which it does in most people who have spent years on a high-carbohydrate diet — the brain stops receiving that signal. It behaves as if you are starving, regardless of how much fat you are carrying.
The result is chronic hunger, a suppressed metabolism, and a body that stubbornly holds onto fat no matter how little you eat. This is the core problem the NKFB method is designed to fix.
The method addresses fat burning across six factors simultaneously. Pull just one lever — as most diets do — and the others work against you. Address all six, and fat burning becomes the metabolic default.
The foundation. Until the brain can receive leptin signals correctly, every other intervention is compromised. Lowering dietary insulin is the primary mechanism.
The 5 Leptin Management Rules →High insulin locks fat in storage. You cannot burn fat and store fat simultaneously. Reducing carbohydrates allows insulin to normalise and opens fat burning.
The Glucose-Insulin Roller Coaster →The body can run on glucose or ketones. Most people have not used fat as their primary fuel in years. Keto adaptation restores that capacity over 3–4 weeks.
The 28-Day Adaptation →Fat is the fuel — eating enough of the right kinds is essential. Natural animal fats, olive oil, and oily fish. Industrial seed oils out entirely.
Good Fats vs Bad Fats →The programme in your head matters as much as the protocol on your plate. NLP, goal setting, and stress management are built into the NKFB system — not added as afterthoughts.
What NLP Has to Do With Weight Loss →What works for one person does not always work for another. The NKFB programme includes a dedicated tracking guide to build a feedback loop that keeps the protocol working over time.
The Full Overview →Switching from glucose to fat as a primary fuel takes time. The body needs to upregulate the enzyme systems that process ketones efficiently — a process that takes approximately three to four weeks. Understanding what happens each week prevents people from quitting when the transition gets difficult.
Glycogen depletion, rapid water loss, and the onset of "keto flu" — headaches, fatigue, brain fog. Caused by electrolyte shifts and the fuel gap before ketone production ramps up. Manageable with salt, magnesium, and hydration.
Ketones are being produced but not yet used efficiently. Energy is inconsistent. This is the week most people quit — and the week they are closest to the turn.
The shift becomes noticeable. Energy stabilises. Hunger between meals decreases. Mental clarity often improves. Fat burning is now the default, not the exception.
Full adaptation. Many people naturally move to two meals a day because hunger between meals has effectively disappeared. Fat loss accelerates as body composition begins to change.
