The PCOS Guide You Wish You Had Sooner

I’ve been there. Frustrated. Exhausted. Wondering why nothing I tried actually worked. That’s why I created these books. Not to give you more empty advice, but to finally give you answers.

Whether you’re ready to understand why your body feels stuck or need clear steps to start changing it, a Low Insulin Lifestyle can help you reclaim your health—and your hope.

Inside the Book

Explore sample pages from Ali Chappell’s personal journey and the science behind a Low Insulin Lifestyle.

I wrote this book because I was desperate for answers that didn’t exist. Years of frustration, confusion, and dead ends led me here. This isn’t just information—it’s what I wish someone had handed me when I felt lost. My goal is simple: help you finally understand your body, your PCOS, and how to change everything.

Years of weight gain, unpredictable cycles, and feeling like my body was working against me. I tried every diet, every supplement, and followed every piece of advice, yet nothing changed. This section opens up about what it feels like to be stuck in a body that won't respond, and why so many women with PCOS feel exhausted and defeated. This is where my story began.

Inside, I explain the science behind PCOS and insulin resistance in a way that finally makes sense. You’ll have ah-ha moments, your jaw might drop, and you’ll finally get answers to questions no one else has been able to explain. You’ll walk away understanding your body and what it needs to finally work the way it’s supposed to.

This is where everything comes together. A Low Insulin Lifestyle isn’t a diet or a short-term fix—it’s a sustainable way to lower insulin, balance hormones, and help your body work the way it should. Practical steps, simple swaps, and realistic changes that give you back control over your health.

Great book for any beginner, scientist, PCOS female, diabetic, health nut – or anyone in between. I have been studying this stuff for 4+ years and I still get mixed up on what hormones do what in the complex syndrome that is PCOS. Dr. Chappell had so many great analogies that helped make a complex topic user friendly. Looking forward to sending this book to so many of my friends who struggle with PCOS and hope this gives them empowerment in this diagnosis. As a physician who doesn’t have PCOS, this is still a phenomenal read and will certainly shift how I personally practice medicine in the years to come.

I absolutely loved reading Ali’s book! Everything from her own journey, which is incredible relatable, to her in-depth knowledge on insulin and diet. I thoroughly enjoyed her breakdown of how the system works with insulin and what I can do to change what I eat to change how my body responds. She is a strong advocate for women with PCOS to also advocate for themselves in many ways to search for answers and Ali’s book certainly helps with the results. 5 stars!

Editing this review after practicing this lifestyle for 8 weeks now. My acne has cleared up after 25 years, my energy levels have increased, I can think more clearly, and I’ve lost the remaining 5lbs I’ve been struggling to lose. Low Insulin Lifestyle is an incredibly enlightening and empowering book that has transformed my approach to health and well-being. Highly recommended for anyone seeking a positive and science-backed approach to improving their well-being. Should be mandatory reading for health care practitioners. It was the first book in years I was able to read cover to cover. It’s as if the author was speaking directly to me.

This book is truly a life saver! I struggled with my weight due to pcos for 15 years. I always bounced up and down with weight and could never figure out how to lose consistently or how to keep it off. I have always been consistent in the gym and did clean eating but my weight still wasn’t moving consistently or at all most of the time. Finally I found this amazing book and have followed the low insulin lifestyle and I have dropped 20lbs over the last few months. Upon reading it I realized what was happening with my body and I was able to realize why I wasn’t loosing weight despite eating clean and even being on appetite suppressants! This book is truly a blessing to have came across.

I loved this book! So well done, clear data represented, this is information you won’t find through your doctor. Everyone could benefit from this way of eating and it’s surprisingly easier than I thought it would be. Cravings are down, which is huge win for me.

This book has so much vital information I wish I knew sooner. It’s written in a way that speaks to my struggles and has helped me take the blame off my shoulders. I’m changing my lifestyle, hoping to get off metformin. Down almost 5 pounds in the first 2 weeks after years of being stuck.and discouraged. I hope this is a lifestyle change I can implement with my family.

When this book came in the mail, I started reading and couldn’t stop! I learned so much. While there is a lot of science included, it is very easy to understand and also very necessary to fully understand why this lifestyle makes so much sense. It is not just for women with PCOS, but everyone can benefit from making these dietary changes. I have tried many eating plans that were just not sustainable so it was great to see in her comparison of different plans, why those probably weren’t the best ones for me in the first place. I am slowly trying to make better choices for our family around the advice given in this book.
