Keto Answers – Book Review


keto answers book review

Have you ever had a keto question?

If so, Keto Answers absolutely delivers as the premier low-carb resource and authoritative keto encyclopedia. 

This is the first publication from Dr. Anthony Gustin, DC, MS and Chris Irvin, MS. You can find it here on Amazon.

Briefly about the authors,

Dr. Gustin is a functional medicine clinician and used low-carb, real food diets with thousands of clients. He is also the founder and CEO of Perfect Keto.

Chris’s background is as a nutrition science researcher and writer with an expertise in ketogenic dieting. He is also the Education Manager at Perfect Keto.

Together, Dr. Gustin and Chris host the Top 50 health podcast, The Keto Answers Podcast.

Regardless of your education or experience, this book is your ultimate weapon in overcoming obstacles and achieving your health goals. Keto is not easy. It flies in the face of most conventional wisdom on nutrition. There is a lot to sort out, which is tough when there is an avalanche of information on the internet.

I wish this book was around when I started keto. 

Why I Started Keto

When I first got started with keto, my main goal was simply to lose weight, and I had the hopes of losing that weight quickly.

After a couple of failed attempts to enter ketosis (I was truly unaware about how so many foods had high amounts of carbs), I decided to get serious and start researching all of the questions I had.

That research is partly why I started Keto Lifehacker in the first place. And after reading Keto Answers, I absolutely know that I would’ve shortened my weight loss timeline and would have suffered a lot less trial and error if the book was around when I was first getting into this diet.

Here’s what you can expect from the book:

The Format of Keto Answers

  • 268 most asked keto questions in Q&A format. 
  • 50+ beautifully designed infographics 

Picture yourself as the host of a Keto Answers Podcast episode and your guests are Dr. Anthony Gustin and Chris Irvin. This is an engaging conversation, not a lecture. 

How to Read Keto Answers

You can either read it front to back or use it as a keto reference guide to revisit when you have a question. Keep your post-it notes and highlighter handy. 

The book is broken down into 4 sections. I’ll share the highlights of what you’ll find in each and I’ll include a few infographics along the way.

Introduction: How Did We Get Here?

In today’s world, we’re constantly inundated with content about nutrition. Too much inaccurate information not backed by science. 

However, this isn’t just a problem that exists today. In fact, Ancel Keys, a very successful scientist led the charge on demonizing fat as a cause for heart disease and is a huge reason why we’re here today. Obesity, heart disease, and diabetes are the most prevalent they’ve ever been.

In contrast, history gets it right sometimes. After all, Hippocrates famously said, “Let food by thy medicine and let medicine be thy food.” around 400 BC. 

Why Keto Now?

Dr. Gustin and Chris Irvin believe these to be the four pillars of health:

Each plays an essential role in health, but nutrition is at the top as it has the largest impact on overall health and wellbeing. Given you have control over what you eat, keto (done right) is a powerful tool in teaching you that nutrition can change how you experience life. 

Keto is crucial right now because it will help reverse the damage of this massive failed nutrition experiment we’ve run on ourselves for the past 30 years.
