“Ultrarunners drop out of 100-mile races due to gut distress more than any other reason. The Athlete’s Gut is a godsend. It presents practical, efficacious, and immediately applicable advice that any ultrarunner can benefit from. It’s a resource I will use with every single one of my athletes as well as with our entire coaching staff. It’s that valuable.”

– Jason Koop, Head Coach of Ultrarunning at CTS and author of Training Essentials for Ultrarunning

“The Athlete’s Gut is a great resource for any endurance athlete who has ever felt limited by some gut-related issue . . . and, really, who hasn’t?”

– Matt Fitzgerald, author of The Endurance Diet and Racing Weight

“The path to a happy gut is nuanced and context specific. Dr. Wilson lays out the causes and possible solutions for a long list of symptoms.”

– Alex Hutchinson, The Globe and Mail

“Races aren’t won at the dinner table, but they can be lost there, and nutrition science is becoming increasingly important to athletes. We’re unique beings, however, and the science is not always one-size-fits-all. With The Athlete’s Gut, Wilson addresses the workings (and malfunctions) of our guts to better understand how to make nutrition science work for us, as individuals with peculiar innards.”

– Chad Haga, WorldTour cyclist, stage winner in the 2019 Giro d’Italia

“I found The Athlete’s Gut extremely useful on three fronts. One, it deals with a topic that’s immensely important to endurance athletes, but not covered or discussed enough. Two, it’s deeply evidence-based; Wilson is a true expert in the field, and he backs up all his major points with the best and newest research. Three, and most surprisingly, he writes with a sense of humor. The topic seems like one that wouldn’t be much fun to read about, but Wilson keeps it entertaining.”

– Amby Burfoot, 1968 Boston Marathon winner

“The Athlete’s Gut combines the latest research on gut health with relatable stories from athletes.”

– Runner’s World UK

“Dr. Wilson uses anecdotes and humor to explain and simplify complex anatomy and physiology in a way that any athlete will be able to relate to. Causes of, and prevention strategies for, gut issues are at your fingertips, as well as a plethora of ‘fun facts’ and well researched scientific insight.”

– Dr. Martyn Beaven, The University of Waikato Adams Centre for High Performance

“For athletes, coaches, and practitioners interested in learning more about the athlete’s gut, Dr. Wilson has created a go-to, science-based resource. It is comprehensive, funny, and packed with useful information glued together with easy-to-understand stories and analogies!”

– Jeff Rothschild, MS, RD, sports dietitian

“Dr. Wilson marries his brains about the gut with his witty humor to produce The Athlete’s Gut. You will eat this book up fast! It is an easily digestible, science-backed read that will educate and entertain at the same time. If you are a weekend warrior or a professional athlete that has some crappy issues to deal with, this is a must-read. Be ready to laugh out loud a few times while learning something new along the way.”

– Tommy Jensen, MS, RD, Director of Sports Nutrition at University of Minnesota

“Dr. Wilson takes a well-thought-out approach to explaining the intricacies of the athlete’s gutspecifically, expanding on topics such as how stress and anxiety influence gut symptoms in relation to performance. His use of wit and humor, blended through relevant anecdotes and peer-reviewed research, make the concepts interesting and enjoyable. The summaries at the end of each chapter were a great way to wrap up essential material in an easy-to-understand format that may be useful to students, athletes, and practitioners.”

– Dr. Leilani Madrigal, PhD, CMPC, Assistant Professor at California State University, Long Beach
