If you’re interested in doing the low carb, high fat keto diet, you may want to dive into a good book on the subject to learn all you can about it.

Keto is a low carb, high fat diet that was originally developed for children with epilepsy. However, it has gained popularity in recent years as a diet for weight loss and blood sugar management.

Researchers have found that it may be effective to help manage obesity and type 2 diabetes because it switches the body from burning primarily carbs to primarily fat and, as a result, may help reduce appetite and regulate blood sugar levels (1).

However, keto is much lower in carbs than other low carb diets, consisting of only 50 grams of carbs or fewer per day.

Making a sudden change to a keto diet can affect many aspects of your health, such as physical performance and electrolyte balance, so it’s a great idea to read up before you get started (2).

Here are the best keto books of 2022.

Healthline assembled this list of the best keto diet books based on the following criteria:

  • Ratings: Does the book have high ratings and favorable reviews?
  • Author expertise: Does the author have an degree, experience, or credentials that boost their credibility as a keto diet expert? This is important when shopping for books about health and fitness. We looked for books written by health professionals, such as doctors or dietitians, and cookbooks written by experienced or professional cooks.
  • Thoroughness: Does the book provide a thorough and comprehensive look into the keto diet?
  • Price: Most books on this list are right around $15, but some may be more or less expensive. Newer or more thorough books tend to be slightly more expensive.
  • Type of book: Are you looking for an informative guide to keto, a review of the science, or a cookbook? This will significantly narrow down the list of books that are a good fit. We’ve included a variety.

The keto diet is wildly popular, and you can find hundreds — if not thousands — of keto diet books online.

However, not all of these books are credible. To identify credible books about the keto diet, look for those that are written by keto diet experts.

These experts may be physicians, dietitians, or other healthcare or wellness professionals with experience working with the keto diet. Or, in the case of cookbooks, they may be food bloggers or chefs who are familiar with recipe development and testing.

You should also avoid books that make dubious or outlandish claims about the keto diet. While the keto diet has many potential benefits, it’s not a cure-all.

What are the benefits of following a keto diet book?

Reading a keto diet book is a good choice for anyone interested in trying keto. It can be difficult to identify which foods are keto-friendly and which are not, and a book can help you to tell the difference.

Additionally, many aspects of the keto diet may be challenging, and a keto book can help you navigate these and provide tips for success.

For example, a book may be able to provide advice on following a keto diet as an athlete or following a keto diet on a limited budget.

Do doctors recommend the keto diet?

Yes, many doctors do recommend the keto diet. Some, such as Dr. Jason Fung and Dr. Eric Westman, are practicing physicians who have also written some of the books on this list.

However, other doctors do not recommend it for the long term because it may be unrealistic and unsustainable.

Is there anyone that should avoid the keto diet?

Keto may not be a good fit for anyone who has a restrictive eating disorder or a history of disordered eating. Additionally, you should speak with your doctor before starting keto if you have any underlying medical conditions or are taking any prescription medications.

Keto diet books are a great way to learn more about the diet, especially if you’re a beginner.
