Updated October 30, 2023

Intermittent fasting has become an increasingly popular lifestyle choice, and for good reason. When done correctly, intermittent fasting can lead to weight loss, improved health, increased focus, and longevity. With so many options available, narrowing down the best intermittent fasting book for your needs is hard. This article is designed to help! First, a quick intro:

Introduction to Intermittent Fasting

Intermittent fasting is an eating pattern that cycles between periods of fasting and eating. It focuses on when you eat, not what you eat. The most common methods of intermittent fasting include:

  • The 16/8 method: Limit your eating window to 8 hours, such as from 12pm to 8pm. Fast for 16 hours in between.
  • The 5:2 diet: Eat normally five days a week and fast for two non-consecutive days. On the fasting days, limit your intake to 500-600 calories.
  • Alternate day fasting: Fast every other day. On fasting days, limit your intake to 500 calories. On feeding days, eat normally.

The benefits of intermittent fasting include:

  • Weight loss: By reducing your calorie intake, intermittent fasting leads to fat loss and weight reduction.
  • Improved health: Intermittent fasting may lower the risk of type 2 diabetes, heart disease, and some cancers. It can also enhance brain function and increase longevity.
  • Increased focus: Some people experience improved concentration and mental clarity during fasting.

The best intermittent fasting book for you depends on your goals and the fasting method you want to follow. This guide reviews the top 8 intermittent fasting books to help you start on the right foot.

If you’re new to intermittent fasting, we recommend starting with The Complete Guide to Fasting by Dr. Jason Fung. The guide will teach you everything you need to know about the science and benefits of fasting giving you a solid bedrock of information on which to build.
