If you want to lose weight and take your health to a new level, buying a book on intermittent fasting is an excellent place to start.

You can buy all books directly on Amazon as eBook or paperback. For this, I use affiliate links, which give me the equivalent of half an espresso for my work if you strike at a book.

Best Intermittent Fasting Books for 2023

For those in a hurry, here are the top 5 intermittent fasting books at a glance:

How to Find the Most Effective Guides?

Most guidebooks drastically restrict your calorie intake to promise you quick results.

But one study shows that 99.5% of 99,791 overweight women and 76,704 overweight men failed to lose weight successfully through a traditional calorie deficit (Fildes et al. 20151).

Restrictive plans are hard to stick to, slow your metabolism, and cause a yo-yo effect (Fothergill et al. 20162).

Furthermore, an extreme calorie restriction can get your hormones out of whack.

That’s why I’ve compiled the best books that don’t rely on renunciation and instead focus on your hormone balance.

Hormones, not calories, are the key to sustainable weight loss and longevity. The fat-storage hormone insulin determines whether you gain or lose weight (Kong et al. 20133).

Because intermittent fasting is the most effective natural means of lowering insulin levels, countless people successfully lose weight (Catenacci et al. 20164).

Hence, the best intermittent fasting books cover three aspects:

  • Knowledge: Processes in your body explained simply
  • Instructions: actionable, science-backed tips
  • Tools: Plans you can use to get started right away

Books that list intermittent fasting methods on 20 pages and then are filled with trendy recipes cannot meet this standard.

For this reason, cookbooks are in their category on this list.

The essential characteristic of an intermittent fasting book is that it helps you reach your target weight and maintain it realistically.

For this reason, an excellent intermittent fasting book must be backed by a real author with experience in the field.

Unfortunately, Amazon is full of intermittent fasting books written by ghostwriters. And the expertise of these writers in fasting is more than questionable.

You can usually recognize ghostwriters by suspicious pseudonyms in the author’s name. Great marketers often list these books. The covers are often great, but the content is garbage.

Therefore, always keep your eyes open for such signs when buying. Checking the author’s page on amazon is a great way to avoid poorly written intermittent fasting books.

Best Intermittent Fasting Book for Beginners

Intermittent Fasting 101: The Science-Backed Beginner’s Guide to Lose Weight Without Dieting and Working Out – Incl. Meal Plans and 10 Secret Weight Loss Hacks:

As the name suggests, Intermittent Fasting 101 is the best book to start. Ultimately, you should know the primary effects of fasting on your body before you start.

James K.

There is nothing to add to this. Intermittent Fasting 101 is the best book to dive into intermittent fasting quickly and reliably.

Best Intermittent Fasting Cookbook

The Obesity Code Cookbook: Recipes to Help You Manage Insulin, Lose Weight, and Improve Your Health:

The best cookbook on intermittent fasting comes from someone who should know. Dr. Jason Fung is the first medical doctor worldwide to point out insulin’s critical role in weight loss and popularize intermittent fasting.

A cookbook has recently accompanied his global metabolism bestseller: The Obesity Code.

Fung runs a clinic combining intermittent fasting and low-carb to reverse Type 2 diabetes. The Obesity Code Cookbook provides the recipes to go with it.

You’ll find a colorful variety of dishes among the 100 beginner-friendly recipes:

  • Salads
  • Vegetables
  • Fish and seafood
  • Meat and poultry
  • Broths and drinks
  • And even breakfast

Accordingly, people who do not fast with the 16/8 method get their money’s worth here. In short, there is something for every woman and man that works.

A customer says about this intermittent fasting cookbook:

“I bought this cookbook a year ago. I love to cook and enjoy international recipes. I started a low carb and intermittent fasting lifestyle. This cookbook has fulfilled all my criteria! This morning, I made the Gruyere cheese custard and added prosciutto and spinach. Excellent! Recipes can be involved but I don’t mind spending the time when outcome is gourmet! Fortunately, I live in SE Louisiana where growing season is long and ingredients are readily available.”

Best Intermittent Fasting Book for Diabetics

The Diabetes Code: Prevent and Reverse Type 2 Diabetes Naturally:

The next intermittent fasting book also comes from the world-famous diabetes doctor. The Diabetes Code is the follow-up to The Obesity Code. It describes how to cure type 2 diabetes with the crucial lifestyle remedy of intermittent fasting.

Contrary to earlier assumptions, type 2 diabetes is not incurable. I can reverse it the same way it is created: through diet. And that’s what the book teaches.

However, type 2 should not be confused with type 1 diabetes, which is not a lifestyle but an autoimmune disease. Type 1 diabetes, unfortunately, cannot be cured naturally so far.

I love this book because it helps you understand the disease better than most doctors who blindly prescribe insulin, which worsens your type 2 diabetes.

Here you will learn how:

  • The root cause of diabetes
  • How not to treat it
  • How to reverse it naturally

This customer review sums it up:

The author has done a great job of explaining the root cause of diabetes and how to manage/reverse it. Very logical explanations and easy to follow instructions. Highly recommend it to all diabetics.


In summary, in my experience, it is the best diabetes book on Amazon.

“I have been Keto on and off for years and bottom line, what I’m doing isn’t giving me lasting results due to my own poor judgement on occasion. This book mixes science and common information in a nice format. I actually did learn some new info/ techniques with regard to fasting and hormones, which explained some things for me. I experienced every processing emotion from head-nodding in agreement to a few lightbulb moments. Definitely enjoying this as a reference resource!”

Best Guides Are Written by Practicing Authors

Countless books are on the market about intermittent fasting, making it difficult to choose one.

Few know that ghostwriters are responsible for over 95% of diet books. You can recognize fake authors by simple but suspicious pseudonyms as the author’s name.

They often use either non or stock photos for the author’s image.

With the best intermittent fasting books, this cannot happen to you. Behind them are real people who have been fighting through thousands of studies and successfully practicing intermittent fasting.

Therefore, when buying a book, ensure it is based on intermittent fasting and endocrinology studies. You can easily find this out by looking at the sources in the bibliography.
