The X Triangle

Three forces, working as one.

The ABS-X method isn't a crash diet. It's a balance of mind, diet, and movement — designed so healthy weight loss becomes effortless once your habits take over.

🧠

Mind

The most crucial part of the triangle. Reprogramme your habits over a focused three-week challenge, until discipline runs on subconscious autopilot.

Chapter 6 · The Mind
🥗

Diet

The ABS-X eating pattern — Intelligent Breakfast, Clever Lunch, Light Supper — built around the foods you love, so you sustain it for life.

Chapter 3 · Food Guide
🔥

Exercise

Walk on an empty stomach, burn fat reserves directly, and keep food and movement as independent goals — never eating back what you burn.
