Start here

Welcome, Dear Reader. Here’s the whole thing in five steps, gentlest first.

1. Read the Sensible Bit

Two minutes, and it matters. Fasting isn’t for everyone or every moment, and some medicines need your doctor in the loop first. Read it here.

2. Get the free 7-Day Planner

A guided first week, mostly 16:8: skip breakfast, finish dinner by eight. Get it here, along with one good email a week.

3. Pick your rung

Never fasted? Spend a week at 12:12 (dinner by eight, breakfast at eight), then a fortnight or a month at 16:8. Plenty of people stop there for good, and that’s a complete answer. Don’t make a 72 your first fast. Climb, don’t leap.

4. Get the book

The 72-Hour Fast has every rung in the same five sections (what it is, who it suits, how to do it, what you’ll feel, common mistakes), plus the toolkit and the troubleshooting.

5. Write it down

Your first 16:8 teaches you when your hunger waves hit. Your first 24 teaches you what you needed to drink and didn’t. Six months on you won’t remember, unless it’s written down. The PDF journal is free with the book.


The three things that save most fasts: salt and water before food when you feel rough; ride the hunger wave for twenty minutes before you decide anything; and break a long fast gently. Have the kebab on Friday.
