Get 3 months free on our fasting app when you buy the book

Reading about fasting and actually doing it are two different skills. The book gives you the "why" and the food rules that make fasting feel effortless instead of miserable — the app is what keeps you on track on a random Tuesday when nobody's cheering you on. Pairing the two is exactly why we're offering a fasting app free trial with the book: 3 months free on the fastinginpractice.com app when you buy "Intermittent Fasting in Practice."

The Direct Answer

Buy "Intermittent Fasting in Practice" on Amazon, then head to the redeem page on fastinginpractice.com to activate 3 months of free access to the app. The process takes a couple of minutes: purchase the book, find your order confirmation, and enter the details on the redeem page to unlock your free trial. No credit card needed for the trial period, and you can cancel before it renews if the app isn't for you.

Why the Book and the App Work Better Together

The whole premise of the book is that fasting isn't about willpower — it's about knowledge and repetition. Mark James, the author, didn't come at this from a lab or a nutrition degree. He was 42, overweight, smoking, dealing with a fatty liver, when he started fasting in 2021. What got him from there to teaching hundreds of thousands of people wasn't discipline in the white-knuckle sense — it was understanding why fasting works and then repeating the same simple structure until it became automatic.

That's where most people get stuck. They read a book, feel motivated for four days, and then life happens — a late meeting, a bad night's sleep, a weekend trip — and the structure falls apart because there was never anything holding it in place except memory and mood. The app exists to solve exactly that gap. It tracks your fasting window in real time, shows you where you are in the process (still burning glucose, moving into ketosis, deep into fat-burning), and gives you a simple daily record so you're not relying on willpower to remember what you're supposed to be doing.

This matters because the book's core teaching is that fasting stops feeling hard once it becomes routine — usually somewhere around the ten-day mark, once your body stops expecting food on the old schedule. The app is what gets you through those first ten days without losing track, and what keeps the routine intact once it's built. Knowledge from the book, repetition from the app — that's the whole formula.

Getting the Most Out of the Combo

• Use the book for the "why," the app for the "when." Don't try to hold your eating window in your head — let the app track it so your mental energy goes toward food choices, not math.
• Don't skip the food philosophy just because you have a timer. The app tells you when to eat; the book tells you what. Fasting on the right window with the wrong foods (sugar, seed oils, packaged snacks) still leaves you hungry and stalled.
• Log consistently, especially in the first two weeks. The early days are the hardest part of any fasting routine, and having a visible streak in the app is often what keeps people from quitting on day six.
• Revisit the book's troubleshooting sections when something feels off. Headaches, dizziness, or stubborn hunger usually trace back to food quality or electrolytes — the book covers the fixes, the app helps you notice the pattern.
