The Thyroid Fix: The No-Nonsense Guide to Fix Fatigue, Fogginess, and Fat That Won't Budge
A definitive and thorough handbook from 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 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.

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.

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.....

Lots of good information that I didn’t know.

May 24, 2026I 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).

I had to chew on this one a bit and consult other resources to verify her claims and my jury is in. This is a dangerous book with very unsafe advice. Hornaman has blasted her thyroid with iodine to a point of complete lifelessness so it is no wonder she has to supplement all of her thyroid hormones. There may be some nuggets in there for people who have had their thyroid removed or radiated to the point that it's beyond hope but I would not trust her judgement on nearly anything.
Some specific red flags:
-She encourages mega dosing iodine as her #1 supplement recommendation. Excess iodine is a primary driver of thyroid disease, which has been validated by replicated population studies (a good overview of this is in the beginning of the book The Thyroid Reset Diet).
-She encourages excessively high doses of vitamin D, which, among other things, can actually de-mineralize bones if your ratio of vitamin D and calcium absorption is too out of balance
-I have not yet researched the concern around T2 supplementation from mainstream medicine but she encourages supplementing T2 without even mentioning that mainstream medicine considers it hazardous to your heart health in supplement form.
I'm sure there are others but this is what is top of mind.
----
Former review:
When you listen to Hornaman, you can definitely hear the bodybuilding ethos of her history. She definitely brings the same biohacking, N=1, experimental mentality to body optimizing that the bodybuilding community is known for. Her perspective is an interesting counterpoint to the mainstream medical approach and, if what she claims is true, she originally arrived at her findings through her own trial and error process of managing her hypothyroidism. I find that a useful perspective to consider but some of her advice is blatantly contraindicated by mainstream endocrinology, such as taking mg of iodine every day based on how it makes you feel or taking T2 supplements.
Here is source specifically on the contraindication of excessive iodine supplementation, for example:
https://doi.org/10.1210/endrev/bnae019
Thankfully she does cite her sources so I will have to compare and contrast to see how much I agree with her, which is a laborious task. I would have appreciated if she included in her book this compare and contrast as she often claims the "science" is on her side without going into details, which is a pretty high claim with how much she contradicts mainstream healthcare.
There's also a frustrating lack of nuance in this book. Applying an evidence-based medical approach to your problems means evaluating the evidence-basis or quality of an intervention. A meta-analysis of duplicated, randomized-controlled trials (RTCs) is the gold standard for evidence (i.e., Cochran reviews), but these are very expensive and aren't going to be available for a wide variety of treatments. Consequently, low-quality evidence interventions are applied all the time in medicine, especially as clinicians find success with these interventions with their patient populations. It's still important to articulate what the "science" does and does not say about the efficacy of various interventions. Hornaman owns a supplement line and includes a breakdown of the ingredients in her own supplements in this text and why they are helpful. However, she only says, "if you take this it will help with that." She acts like they are interventions with the same quality of evidence as drugs despite lacking the supporting evidence. To her credit, however, she does frequently cite the importance of running labs, generally starting low with new medications (like T3), and checking the labs to see how they have helped or hurt your progress.
Why would I consider her perspective at all? I respect doctors and mainstream medical science but we also know that healthcare, particularly in the US, is run as a business. Pharmaceutical companies don't want to sell cures as there is no money in that and have been found guilty of selling contaminated blood because the resulting lawsuits were cheaper to deal with than the profit loss of actually removing the contaminated blood from their merchandise. For this and many other reasons (systemic misogyny and racism, for example, which lead to poorer health outcomes for marginalized groups), it's important to be your own advocate for your health.

The loss of my quality of life means nothing to the medical system, so I understand what the authoris saying, but using studies done on mice and rats to state things as fact is not good.
Lathering on wellness concepts ("eat clean", "detox naturally"), talking of "gaining weight" more than any other symptom, and using a whole chapter to pimp her T2 supplement shows more profiting from the pain of others than genuinely wanting to help.

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.

I was pleasantly surprised by this book. I won it in a goodreads giveaway. I expected it to be the typical influencer book, a lot of fluff with a little substance. I expected the author to be very high pressure for her website and her supplements. She mentioned both in the book. However, her focus was mainly on helping people identify their issues, giving them information on how to interpret their results and some excellent language to use when asking your doctor to do the necessary tests to get to the bottom of your thyroid issues and get the treatment that you need to be healthier and have better control over your health. There are 15 chapters in this book and I felt like the most valuable information for me was contained in Chapters 9 - 15. If you have been struggling - this book will definitely get you heading the right direction towards recovery.
Review of advance copy received from Netgalley
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).

Review of advance copy received from 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.
October 6, 2026
I was excited for this book, but this was not helpful for various reasons. Lots of focus on how with thryoid issues you are gaining weight, which is not an issue for me as much as other things. I also don't need someone who is a doctor of nutrition (not an MD) to write a book using the word badass so many times, plus talk about her own supplements...Still, some good info, but not my fave thyroid book, esp a lack of understanding of reasons why people are vegetarian/vegan.

Very informative for those with thyroid issues. Thank you to Amie Hornaman and Goodreads for my ARC.
October 18, 2026
I'm not that smart but I knew everything here already.
October 24, 2026
As a general reader, I found this book is both informative and potentially dangerously misleading. Biohacking gets out of hand easily, mkay?
July 15, 2026
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!
July 11, 2026
This was definitely informative. I learned a few new things. Basically one has to take supplements to combat thyroid deficiencies.
September 8, 2026
If you have no knowledge of the thyroid and how it impacts your body when it’s out of whack, then this book will likely be enjoyable and educational. It’s also disappointing how obsessed Dr A has become with prescriptions “they’re bio-identical” so it’s fine in her mind. Yet, never addresses that taking meds doesn’t actually heal you or get to the root of the problem.
