The Thyroid Fix: The No-Nonsense Guide to Fix Fatigue, Fogginess, and Fat That Won't Budge

by Amie Hornaman

A definitive and thorough handbook from the fun and personable Dr. Amie Hornaman (a.k.a. “The Thyroid Fixer”) that brings functional medicine and self-advocacy to the underdiagnosed epidemic of thyroid issues, particularly in women.

It’s not you; it’s your thyroid.

If you feel like there’s something wrong but you can’t get a doctor to listen, don’t have a diagnosis yet, or have a diagnosis and your treatment isn’t working, this book is for you. People—especially women—are consistently being dismissed and encouraged to accept symptoms that are anything but weight gain that won’t budge, exhaustion that never lifts, hair loss, anxiety, brain fog, and mood swings.

Dr. Amie Hornaman is here to change that. The Thyroid Fix addresses what most doctors the real reason women feel fat, foggy, and fatigued isn’t laziness, aging, or a lack of willpower—it’s their thyroid. This book is a wake-up call—and a solution—for millions of women who are sick of feeling dismissed and misdiagnosed. It’s direct, real, and filled with strategies that actually work.

In this book, Dr. Hornaman teaches you what your lab results really mean, why “normal” ranges are often meaningless, and how to get treatment that actually works for your body. With authority and empathy, she invites you to bust myths, understand your labs, and finally get real answers. Readers will walk away with a self-assessment, facts, and questions to approach their doctors with, and solutions that range from conventional and functional medicine to prescriptions, supplements, and lifestyle shifts.

The Thyroid Fix is the straightforward, clinically-backed thyroid health guide you didn’t know you needed, but that might just change your life.

I’ve found some new information, but basically I need to find a doctor (it could be a man, but at this point I’d say a woman would be better) who believes me when I describe my symptoms. Anyway, this book is good both for people who aren’t experts yet and for those who consider themselves experts, like me, and then discover the existence of T2 and T1...

Ho trovato alcune nuove informazioni, ma fondamentalmente mi servirebbe trovare un dottore (anche maschio ma a sto punto direi che femmina é meglio) che mi creda quando gli racconto i miei sintomi. Comunque questo libro va bene sia per le persone che non sono ancora diventate esperte, sia per coloro che si ritengono tali, come me, e poi scoprono l'esistenza del T2 e del T1.....

I appreciated the visibility she shed on Hashimotos and hypothyroidism. She elaborated well on all the thyroid hormones. Basically, you need to take medicine. There isn’t a “natural” fix that will work, even though the last chapter felt like a mix of several Huberman Lab episodes on biohacking (even though that’s not enough to fix your thyroid).

This book is well written and contains a lot of good information about the thyroid and how it functions. The author does a great job of writing it in a manner that is easy to understand. However, she calls herself functional but treats the thyroid without discussing the importance of finding the root cause of the autoimmunity which led to Hashimoto's. Instead she tries to sell the idea of needing medication without conceding that it might be a temporary need while you find the fix for what caused the hypothyroidism in the first place. She's quite passionate about convincing you that medication is the best option. That is not the functional way. Don't call yourself functional and ignore the basis of functional.

She does a great job of offering ways to talk to your provider and advocate for yourself. She does this in a way that is not inflammatory and won't make the provider feel cornered or dictated to.

For her "no duh" supplements, she gives alternatives, but a lot of her suggestions are her own banded supplements. The book felt a lot like a sales pitch.

She mentions a T2 with glutathione cream/gel that's not available when I search her site. Her supplements are listed as "doctor formulated" but she's a doctor of clinical nutrition. While this is a wonderful accomplishment, she is not very open about this on the bottle. It also makes me curious about her clinical practice, since she's can't prescribe all these medications she discusses.

Finally, she knocks other providers because her patients wasted money (she quotes somewhere between $5,000-10,000), yet her program costs $2,000-10,000 on her site. She says you don't need a jack of all trades but a specialist. Yet not everyone knows if they even have thyroid dysfunction, so a specialist might not be appropriate.

Overall, the book was very educational and informative. It did a good job of disseminating information, but you need to take it with a grain of salt. Understand that she may be a specialist, but she cannot prescribe medication (she does employ others who can prescribe). She also markets many of the supplements she recommends. This decreases her objectivity. On the flip side, she mentions a gel/cream that is not available and if she's going to claim that form is best, it would be nice if it were available.

A valuable resource for any woman who even suspects she may have thyroid problems.
The chapter on suggested nutritional support is especially valuable. You might choose to supplement, or you might choose to get these nutritionals through your food.
But the most important information given is the battery of thyroid lab tests that you need in order to learn what is really going on with your thyroid. Most doctors just order one test, tell you everything is fine and send you on your way. But Dr. Hornaman explains what each lab test measures and why it is important to get a clearer picture of what is going on. And she tells you that you can demand that your doctor run these tests even if the doc normally never bothers with them.
This is empowering.
I would caution you regarding becoming an online patient of Dr. Hornaman. The office charges thousands for her attention, and routes you to another party for a loan to cover the cost. That does not seem kosher to me at all.
But by all means get the book and glean all you can, then arm-wrestle your doctor to do the proper lab tests. You have to become the engine behind guarding your own health and well-being.

As a hashi patient, I’ve read several books on this gland. This one is very easy to digest, a quick read and contains useful information. My biggest takeaway: thyroid meds need to be personalised. And as of today, I haven’t found a single Dr willing to do anything for me but charge a boatload to fatten up their wallet. Hmmm. Maybe I should write their names here, so you ladies don’t fall for those scammers, huh? 🫢🫢🫢🫢🫢🫢😏😏😏😏😏

Also, this book is written for me. I’m reading it after seeing a dr who can’t even wrap around her head the fact that I feel lousy every day. She just doesn’t get it. Dr Hornaman dedicated the book to women like me, so there’s that.

Key points I thank this book for:
✅Thyroid care is extremely personalized. What works for one patient doesn’t work for another.
✅Very grateful to Amie for bringing up patients like me who have adverse reactions to Levo.
✅Also grateful to her for writing down the correct functional numbers for FT3.
✅ Supplements and diet alone are not gonna fix a broken thyroid.

Don’t sleep on this, especially if you’re new to a hypothyroid diagnosis. I hate the mentality of just prescribing pills and want to do what I can to fix it. When 12% of this book is references, it’s not a lie that she did the research. This was easy to digest the terminology and the breakdown of different ways to improve your health as long as you’re willing to put in the work. Easily one of the top resources I’ve read or listened to for fixing my thyroid with new, relevant information.

Thank you to NetGalley for an advanced copy (and my new favorite thyroid reference).

I’ve read so many thyroid and other health books that went on for two hundred pages and didn’t offer a fix that I skipped ahead to chapter eight, Can I Heal My Thyroid Naturally? The answer is basically no, unless you have very mild symptoms. The advice is to take meds and then do the standard healthy things like eat right, get sleep, do weight bearing exercises, etc. The author also promotes her own supplements. This might be helpful if you just want to understand various thyroid issues, but there’s no new “fix” offered.

I read an advance copy of this book via netgalley.

The last 10% or so of the book is reference from all the research, I am still just a little hesitant taking advice from someone that is promoting their own supplements throughout the book. With that said, I still think there is a lot of good information in this book. I give it 3.5 stars rounded up to 4 stars.

I think this book is absolutely essential to read if you’ve ever been diagnosed with or even suspect a thyroid problem. Sooooo many women need to read this!

[Sonja · Rating 4 out of 5]

This was definitely informative. I learned a few new things. Basically one has to take supplements to combat thyroid deficiencies.
