Publisher's Summary

A bold new plant-based plan that challenges popular keto and paleo diets, from an award-winning gastroenterologist.

The benefits of restrictive diets like paleo and keto have been touted for more than a decade, but as renowned gastroenterologist Dr. Will Bulsiewicz, or "Dr. B", illuminates in this groundbreaking audiobook, the explosion of studies on the microbiome makes it abundantly clear that elimination diets are in fact hazardous to our health. What studies clearly now show - and what Dr. B preaches with his patients - is that gut health is the key to boosting our metabolism, balancing our hormones, and taming the inflammation that causes a host of diseases. And the scientifically proven way to fuel our guts is with dietary fiber from an abundant variety of colorful plants. 

Forget about the fiber your grandmother used to take - the cutting-edge science on fiber is incredibly exciting. As Dr. B explains, fiber energizes our gut microbes to create powerhouse postbiotics called short-chain fatty acids (SCFAs) that are essential to our health. SCFAs are scientifically proven to promote weight loss, repair leaky gut, strengthen the microbiome, optimize the immune system, reduce food sensitivities, lower cholesterol, reverse type 2 diabetes, improve brain function, and even prevent cancer. Restrictive fad diets starve the gut of the critical fiber we need, weaken the microbes, and make our system vulnerable. 

As a former junk-food junkie, Dr. B knows firsthand the power of fiber to dramatically transform our health. The good news is that our guts can be trained. Fiber-rich, real foods - with fruits, vegetables, whole grains, seeds, nuts, and legumes - start working quickly and maintain your long-term health, promote weight loss, and allow you to thrive and feel great from the inside out.

With a 28-day jump-start program with menus and more than 65 recipes, along with essential advice on food sensitivities, Fiber Fueled offers the blueprint to start turbocharging your gut for lifelong health today. 

Includes a PDF of recipes and shopping lists.  

PLEASE NOTE: When you purchase this title, the accompanying PDF will be available in your Audible Library along with the audio.

best book on nutrition since how not to die

I heard Dr. B on a plant based podcast and i just finished listening tothis book for the THIRD time. I'm a plant based nutrition fiend and this is the best book ive read since dr. Gregers how not to die, which changed my life, my partners life, and though we didn't know it at the time, our daughters life. this book gets into the mechanism behind how plant based eating improves health - the microbiome! dr. B is no Michael Greger.. the studies cited are not reviewed in detail, but clearly he is well read and leads with the studies. he gets an A from this research methods professor. I also loves the discussion about behavior change and growth mindset. and the best part is that this book encouraged me and my partner to cut out the processed junk from our vegan diet and reclaim the whole-foods in whole-foods-plant-based. can't wait to see how my kraut turns out! thanks dr. b.

Gut info is fantastic, vegan emphasis is not.

Dr. Bulsiewicz clearly knows what he is talking about when it comes to fiber and gut health. That information is worth the price of the book. I particularly enjoyed his de-bunking of the demonization of plant foods - grains, legumes, nightshades, etc. However, he then goes on to demonize all animal foods using the same types of limited and flawed arguments and studies that he unraveled on the plant side.
In summary, the gut health information is great. As far as whether a vegan diet is a good idea for most people, or even best for the environment - I would have liked to see a more balanced and well-researched treatment.

Unnecessary information

This book could be a lot shorter. The author continues to use technical long words to increase the length of the book. The important information could be provided in less than two hours. The book Digestive Wellness by Elizabeth Lipski was much more comprehensive.

first science driven nutrition book i have read

I have struggled with gut health over the past year. I have listened to many nutrition books that claimed to be driven by science or human evolutionary history. Unfortunately many of these were filled with flawed logic and a poor understanding of general scientific consensus. This book was different. It was based on a thorough review of available scientific literature. The advice in this book has also been highly effective at improving my gut health and overall feeling of health. I highly recommend this audiobook.

High expectations

There is some good in this book but I kind of had hoped that it would go more into how to transition into a vegetarian diet. It just gave the tired old go slow advice. The end of the book got boring and I could not finish it. The narrator has a lot of enthusiasm but he doesn't really have a full quiver to work with. I would have preferred a slightly more organized approach. The PDF has a shopping list and the first week is an explosion of vegetables etc. For someone like me, who is trying to transition, it would be too much for me to handle.

Good introduction to the microbiome

Not a bad book, but I expected more from a doctor who is a specialist in this field. There's a fair bit of repetition and filler. Probably a good read for someone who doesn't really know anything about gut health, but it could do with a bit more substance. The audiobook I read just before this was Dr Michael Greger's How Not to Diet. This book seems a bit lightweight by comparison.

A MUST for anyone trying to understand the gut

Let me start with the writer's CV:

- Med school at Georgetown School of Medicine
- Trained in medicine at Northwestern Memorial Hospital
- Trained in GASTROENTEROLOGY at The University of North Carolina Hospitals
- Got Master of Science in Clinical Investigation (MSCI) from Northwestern University
- Certificate in nutrition from Cornell University.
- Board-certified in internal medicine and gastroenterology

Given all the 'gurus', non medical doctors, influencers or even journalists online spreading their misinformation on gut health it was refreshing to see someone who is actually more than qualified to talk about it. Very thorough research, very well explained and from credible sources and studies. Definitely A MUST for anyone trying to understand the gut.

Good book, but won't play on my mp3 player.

I was looking forward to listening to the whole book but I just can't get it to play on my mp3 (Sandisk clip sport) player no matter what I do, every other book from audible plays fine so I don't know what the problem with this one is (and it is in the same enhanced format as my other audible books). From what I've listened to so far on my PC it is very interesting, and it comes with a helpful PDF. I'll get the kindle version too so I can read it properly. The challenge to eat 40 different plant foods a week is a great way to make healthy eating more interesting as it shifts the focus from removing "bad foods" to increasing good ones. I have IBS so I kind of cheat somewhat by making food into soups and smoothies and sometimes peeling fruits and veg, and I rarely eat salads, but I have still felt the benefits of eating a more diverse range of plant foods.

Simple map to health

This is a good health bible. All advice well explained and easy to follow. Yes we all know we should eat our veg. This book explains why and says how the author managed to put the building blocks in place for his own life. He is an expert in this field. There is a lot of content. The audiobook helped me plough through all the information. Definitely worth it. I have been inspired and feeling the benefit

I’ve always known about the gut due to lots of intolerances I have and research I have made due to it over the years, but I didn’t know the information in this book. My mind is blown and I cannot wait to implement this information. THANK YOU SO MUCH! You have given me hope!

I found the guy reading the book a bit annoying I must admit, but the content was good. It would have been much better if Will B read it himself. Other than that, very educating. It just makes sense.

Absolutely Amazing!

I first heard of Dr B whilst listening to the Plant Proof Podcast by Simon Hill and was completely taken back by his knowledge. It has changed the way I eat and my relationship to food for the better and I'm so happy his book has finally come out so others can benefit aswell!
