If you've read more than 1-2 books on plant-based eating and gut health/gut bugs, you won't find much new information here (perhaps a new study or two).

HOWEVER, this book is very concise and a terrific summary of information. The author's voice and writing style are fun. Bulsiewicz keeps the readers interested by being charming, entertaining, friendly, and not being too serious. While many other books on gut health/fiber/plant-based diets can become boring and dry, this one does not. Bulsiewicz

Eating a wide variety of whole plant foods is the path to a diverse, healthy, and thriving gut microbiome, which is a vital component of total health. In Fiber Fueled, Dr. B does an artful job weaving together facts, statistics, and clinical research findings in a thorough, easy to understand, and often humorous way. I learned so much about why and how a healthy microbiota creates body wide health and—most importantly—I learned how to use easy-to-access foods to nurture my microbiota. This is an ...more

Imagine reading 600 medical studies on gut health. Well you don’t have to. Dr B has taken all the science (the real stuff, not the studies endorsed by for profit companies, or spanning one week with 2 people), and compiled it in laymen’s terms.
This book contains so much amazing knowledge. If you eat and poop, it will help you. And you’ll enjoy diving in. Seriously, this is a fun read.
For me, being plant based and having a long history of gut issues, it is proving to be a catalyst. I’m looking

**UPDATE** 3.26.21
after decades of food sensitivities and gut issues, thanks to Dr. B’s wisdom, I have completely reversed every single sensitivity (including gluten and soy). Fiber Fueled and his Plant Fed Gut course helped me to finally heal. Gone are the days of bloating and pain, and fear of food is now a thing of the past. I’m incredibly grateful to his research and passion to help people.

While my family and I already eat a plant-based diet, I appreciated the reminders for diversity - espec
Recommended for those who, like me, have been searching for good information on the microbiome and how to “cultivate your own garden.” I chose this book because the author of How Not to Diet: The Groundbreaking Science of Healthy, Permanent Weight Loss gave it a thumbs up and the two men certainly share a worldview.

I aspire to increase my plant intake and both books are inspiring for that goal. I'm unsure that I will ever be vegan, but I have no doubt that more plant based meals will be an impr

Sixty percent of your poop is bacteria. You're welcome.

I mostly scanned or skip-read this book, so it wouldn't be fair to give it a rating. I was already essentially eating this way before reading the book, and it just gave me more reasons to keep doing what I'm doing and strive for even more plant diversity.
Haven't tried any of the recipes yet.

Authoritative, but Sometimes Heavy-Handed

Fiber is good for you. Plant based eating is good for you. Sauerkraut.

This book starts out with the absolute basics and is cheerfully encouraging if you are new to the nutrition and diet wars. There are clear descriptions of the types and sources of dietary fiber, the differences among pre-biotic, pro-biotic, and post-biotic choices, and the specific benefits of different foods. There are some interesting facts and tips and insights about different foods

Fiber Fueled by Will Busiewicz or Dr. B, has been a game changer for me. I wanted to read this book, because I had hoped to read something that would aid me in my weight loss, but what I found instead surpassed all my expectations. I tick almost all his boxes for damage to the gut microbiota and the rest of the book was eye-opening.
You get in depth, expert information on your gut and the importance of fiber. This part, the theory, takes a moment to read as it is very medical, but Dr. B does a g

Learning about my good bugs, my bad bugs, fecal transplants, and seeing the worlds “poop selfie” in a book thoroughly excited me...truly I was living for it.

This shit is fascinating.

However, as a weight loss approach...upon reading worlds like “unlimited/no restrictions/Mother Nature has counted the calories for you” my laws of thermodynamics following self got a little triggered.

Sure. Our microbe is a HUGE factor in what we eat (calories), and Dr. B really fleshed that aspect out.

Initially very convincing, with lots of references to scientific papers and studies. However the writer gets lazier as the book goes on, and starts to contradict himself and use anecdotal evidence for some pretty big parts of his argument.

The plan itself is too prescriptive and as a competent cook, I would have preferred a guide of ingredients and what to increase when. I don't have the resources, time or patience to follow the plan as it is, and it's very hard to extrapolate what is actually ch

Great information in this book. The v science is sound. The explanation are clear. I feel like I understand the gut and microbiome. I understand more clearly why eating processed foods are not healthy.
I would have loved a few more examples of people whose lives have been changed due to making a change to diversity of plants. He teases one at the beginning but never returns to show an outcome.

This book offers insight into the importance of fiber in plant foods and how it facilitates gut health and healing. The author details why fiber is so good for the body, what causes common gut issues, and why strict elimination diets are not the answer to healing them. If you have ever been told/thought of going on a low fodmap diet, read this book! The author includes a 4-week meal plan with recipes (I've made a few and they were delicious) that slowly ease the reader into incorporating more fi ...more

As always, Dr. B does a fantastic job of breaking down complicated science and explaining it in a way that the average person can understand. His case for the "why" is extremely compelling and backed by hundreds of scientific studies. If you're looking for the motivation to improve your health, it's here. Where the book disappointed me was in the "how." The diet/meal plan in the last section of the book is no different than any other. It's extremely prescriptive, and filled with overwhelming lis ...more

Eye opening!

As a person who suffers with multiple food sensitivities, this book is close to my heart. Being a doctor myself I questioned a lot as an individual about the issues he discuss. These recipes are easy to follow and the book is very practical in my opion.
Lots of good information, but the writing style was a little over the top. Enthusiasm is good but this felt at times like an overblown infomercial (even though I do completely favor the plant-based diet). And the 28-day food program seemed pretty complicated, especially if it is intended for people new to vegetarian-type food; I wasn't tempted by it. There are a lot of good plant-based cookbooks out there, so I think the author should have stuck to the science behind the food. Finally, I would h ...more

Good information, but the writing style drove me crazy - it was too light and breezy, constantly self-referential, and personal experience/recommendations were with mixed with talk about research studies. I also think the footnotes and references belong in the book itself rather than on the author's blog. ...more

I could not put this book down. The author provides compelling and riveting insights into the latest science and the causes of many chronic diseases and how to prevent or cure them. Contrary to so many books of this genre, it is based on impeccably researched science and written by somebody with medical and practical experience and credentials. Highly recommended.

While I already follow a whole food vegan diet, it was great to learn about gut health, its importance, and what diversity of plants can do for it. Definitely adding the diversity content to my routine!

If there is a single book you choose to read about health & diet- choose this one. There are a ton of recipes along with being easy to understand for a non-medical professional. I had to keep a highlighter near by while reading because there are that many gems in this book. Highly recommend!!

I have been on the fad diet train (Gluten/Dairy/Grain/Egg Free in various combinations) - largely for healing purposes - for years and I've had some good successes and have learned a lot along the way. After awhile, I began to question the validity of some of these diets as it pertains to diversity of food. Then, I went to Israel and ate my way through that beautiful country eating all of the bread I could get my mouth on...with no adverse reactions despite having been gluten free for many years ...more

LOVED this audiobook and will be preaching about it probably forever. So refreshing for a number of reasons: don’t be afraid to eat fruit, it’s a lifestyle, eat as many GD leafy green veggies as you please, gluten is coo, so are grains and SOURDOUGH BREAD. He even gives you a little wiggle room in his suggestion of being 90% plant based, for those of us who need a little cheese and wine. Just incredible to know how life saving these plants are, not to mention the scientific studies on how garden ...more
