A practical, medically grounded, and compassionate guide to GLP-1 medications, perfect for anyone beginning to consider the possibility of using one, though it may not offer a lot of new info for those who have already done a great deal of reading and research. That said, Weightless traces the (longer than most people realize!) history of these medications, how they work, what to expect on one, and the importance of prioritizing weight training and a diet high in protein and fiber.
I really appreciate that it also gets into the mental and emotional impact of weight loss and body changes, and often not positive ones. I don't think have enough conversations about what its like to realize because something about you has changed physically just how fatphobic the world around us is. I also appreciate how she talks about who should actually be using these medications, what they can treat, and the importance of close medical supervision and taking things slowly. If you or someone you love is taking or considering taking a GLP-1, this is worth picking up. I received a copy of this book for review from the publisher. All opinions are my own.

Weightless (A Doctor’s Guide to GLP-1 Medications, Sustainable Weight Loss, and the Health You Deserve) by Rocio Salas-Whalen, MD is an outstanding and incredibly helpful resource for both patients and healthcare providers.
This book is extremely well written and, most importantly, written for the patient. It walks readers through GLP-1 medications in a clear, approachable way, answering many of the questions people actually have. It explains the different types of medications, how they work, insurance coverage considerations, FDA approval, and much more without feeling overwhelming or overly technical.
The second half of the book focuses on what a sustainable lifestyle can look like alongside a GLP-1 medication. It discusses the importance of eating enough protein, how to determine individual protein needs, and includes practical examples of what a week of eating might look like while working toward protein goals.
I also appreciated the way this book reframes obesity. It clearly explains that obesity is not simply a lack of willpower, but is influenced by hormones, genetics, and other biological factors, all supported by research. This perspective feels compassionate, empowering, and validating.
Additionally, the author does an excellent job covering side effects, contraindications, and how to have productive conversations with your healthcare provider, from the very first appointment through ongoing follow-ups. It equips readers with the language and confidence to advocate for themselves.
I highly recommend this book and fully expect to read it again.
Author Rocio Salas-Whalen, MD is a triple board-certified endocrinologist and obesity medicine specialist who founded New York Endocrinology, a practice focused on personalized care for endocrine disorders like diabetes, thyroid disease, and menopause, with a special expertise in weight management using GLP-1 medications.

Review of advance copy received from Netgalley
4.5 stars. I was able to access an ARC of this book at the perfect time for me, and am very grateful to have had the opportunity to read it. Dr. Salas-Whalen does an excellent job of balancing education about glp-1 medications, compassion for the struggles of patients who are battling obesity and all of the stigma and emotions that often come with that, and practical information on how to navigate diet and other life changes that may occur as patients use these medications. As a therapist, I particularly appreciated the attention given to the emotional impact of living with obesity, making changes and dealing with maintaining that change. I am also intrigued by suggestions for possible new applications of these drugs, for example in working in the field of addictions .And as a person who has spent way too long battling my weight who recently (and with much anxiety) started on a glp-1 medication, I appreciate the compassionate tone and hopeful voice that she brings to this area, and the easily understandable breakdown of medical information. I will definitely be mentioning it to my doctor. Thanks to Netgalley for the ARC!

This book is a must read for anyone who has been obese and is scared to consider GLP-1s. Dr. Salas-Whalen offers a very well researched (with all the resources listed at the end—much appreciated for someone who likes to review journal articles) book on GLP-1 drugs. It includes the history of the drug (much further back than you would expect) along with tips and advice on who could benefit, how to talk to you doctor or find a doctor to prescribe them, all the different drug options, and what to expect when using the drug. The book is easy to read and understand for anyone, not just those with medical knowledge. The content that really makes this book stand out is that Dr. Salas-Whalen makes sure to teach you how to use a GLP-1 with proper nutrition and strength training. This is what so many miss when on a GLP-1 that leads to increased side effects and poor outcomes. Even if you never decide to take a GLP-1, this book offers great information that will really open your mind to obesity and how medications can lead to a healthier population without stigma in the future.
Thank you to Netgalley, the publisher, and the author for an ARC in exchange for my honest opinion.

I was not a fan of this book. I had to finish it because I read it through the goodreads program and have to review it, but I found it to be pretty dull. I think it’s one of those books people might read a chapter or two out of but rarely straight through.
I was very annoyed at the book for not having footnotes but it turned out it had endnotes and they just weren’t set up in the advance reader copy. Oops. So that should be fine for everybody else.
I wanted to learn more about glp1s but maybe not this much. My apologies to the author. The book tries to be less dry by having short patient stories but they weren’t long enough to actually care about the person.
I also felt weird that the author didn’t include anything negative about glp1s. She’s an advocate.

A must-read for anyone on, or even considering, a GLP-1!
I don’t usually reach for nonfiction in the medical sphere, but because this topic is personally relevant to me, I decided to give it a shot (no pun intended)—and I’m so glad I did. This book is incredibly well written, approachable, and impressively thorough. I ended up reading it in a single sitting. While I already knew a fair amount going in, there was just as much that was new to me, and the author explains everything clearly without ever talking down to the reader.
One of the highlights for me was the inclusion of personal stories. They’re varied, relatable, and help ground the science in real human experience. You can tell the doctor behind this book genuinely cares about both the subject matter and his patients. That level of compassion and practicality is something I wish we saw more often in healthcare.
The book does an excellent job dispelling common myths and misinformation surrounding GLP-1 medications. It also gives smart, actionable tips on how to optimize results, outlines what doesn’t work, and dives into both aftercare and what the future of these medications might look like. It feels comprehensive without being overwhelming.
Truly, whether you think you already know everything about GLP-1s or you’re just beginning to explore the idea, this is absolutely worth the read.
I fortunate to receive a complimentary eARC from Rodale Books via NetGalley, which gave me the opportunity to share my voluntary thoughts.
How I Rate
Because I mostly read ARCs, I focus on how I think fellow readers with similar tastes will respond. I sometimes round up or down based on pacing, prose, or overall impact, and I try to keep my personal preferences from weighing too heavily.
⭐️ 1 Star – Finished, but not for me as it has way too many issues; I never DNF ARCs but would have had it not been one.
⭐️⭐️ 2 Stars – Struggled due to writing, content, or editing issues.
⭐️⭐️⭐️ 3 Stars – Decent read with untapped potential; recommend with some reservations.
⭐️⭐️⭐️⭐️ 4 Stars – Really enjoyed it and would recommend for several reasons.
⭐️⭐️⭐️⭐️⭐️ 5 Stars – Exceptional; lingers in my mind well after reading. A story I’d gladly revisit.

This book clearly and without any judgement explains the huge importance of GLP-1 in the field of obesity. Even though I’ve read numerous medical articles concerning this topic, I learned so much more. I was hoping though that there would be some information relating to how this type of medication that diabetics have used for a few years could also help them to understand how weight is not their fault either. There’s still the prejudice of doctors that if you have diabetes that it is your fault. This field of endocrinology as it pertains to weight loss should incorporate both sides of this issue instead of separating them. It’s good there are separate medications for both now, which was an extremely necessary step as seen from the lack of enough medicine produced in relationship to the overwhelming number of prescriptions written in 2023. I as a diabetic could not get my prescription filled at this time and had a 8 month lag. That in turn resulted in my A1c rising and weight increased. The medical field is making huge inroads in weight loss but so much more needs to (and will) be done.

The subtitle describes this book exactly: A Doctor’s Guide to GLP-1 Medications, Sustainable Weight Loss, and the Health You Deserve. She discusses the various weight loss medications such as Ozempic, Wegovy, Mounjaro, and Zepbound and their effects on the body and how used properly can be life savers for those who desperately need them. But not without proper guidance, care and maintenance. Which is what she offers in this information packed book.
Although I have read a number of health books due to a strong interest in self-care, I don’t usually choose to review them. This one, though, caught my attention on Netgalley as there has been a fair bit of discussion about weight loss medications. And although I have no experience with them personally, I do know people who do and thought if this was a good book I could recommend it to them. Little did I realise how much this manual covers and how fascinating I would find its contents.
Weightless begins with an interesting Forward from a colleague who cracks open the truth about obesity: that it has been misunderstood and mistreated. She states that ‘Weightless reframes obesity as the chronic, complex condition it truly is—not a willpower problem but a medical one.’
Author Dr. Rocio Salas-Whalen then begins with an Introduction that is very humbling and powerful by issuing first an apology on behalf of the medical community ‘to anyone who has struggled with weight’. To see such accountability is inspiring. For years patients have been sent home with ‘oversimplified advice’. Drs treated the symptoms (often unsuccessfully) without treating the disease. They ‘did not fully understand it as a medical condition’. But today weight management is seen in a new and positive light thanks to ‘increased aid, research and treatment.’ Although this is great news, the rapid adoption of new drug therapies are being administered without proper training and advice. As Dr Rocio Salas-Whalen states ‘although GLP-1s are revolutionary, they’re just one piece of the complex puzzle.’ She wrote this book to put all the factors together so it works. It includes nutritional and mental health support, too. This comprehensive health journey provides a firm foundation and redefines obesity from being a personal failing or defining trait— to confirming the medical condition it is. And to remove the blame and stigma attached to it in the past.
The book is then broken into Part I, II and III.
Part I - The Road Ahead: Rethinking obesity, Enter GLP-1, Are GLP-1’s Right for you. The Road Starts here. (Within these sections are honest discussions, evaluations and how to find the right provider to assist you on your journey.)
Part II – Your Life Changing Journey Begins: Your GLP-1 Journey and what to expect, Staying on Course: Your GPS for progress, Titration and Troubleshooting
Part III: Life After GLP-1s: Maintaining your weight: strategies for Sustained Success, After the Transformation: Facing Yourself and the World.
This powerful and informative guide delivers the information to patients and their friends and families in a very readable form. Dr. Rocio Salas-Whalen explains the history, misinformation, terminology and how these drugs work and what tools you need to be successful in their use. There are food Cheat Sheets, appointment Checklists and a wealth of excellent advice to those who could really appreciate it. I found that although the guide expands our knowledge of the treatment of weight issues, it covers so much more. Why is obesity a bigger problem today than in the past? The obvious reasons such as less physical activity and more processed foods to consume are mentioned. But also how our radically altered environment has affected us, too. As a result, there have been some subtle changes in our body chemistry. Chemicals in and on foods and those genetically modified surely have added fuel to the fires of destruction. And even when the body manages at some level to adapt or deal with all these negative things, there are still consequences. One area that I found fascinating is how our ancestors’ living conditions changed their DNA. This in turn has been passed down to us in the current age. I actually never thought extensively before about this aspect of our make-up but it certainly makes sense. Those who lived through various famines and the Great Depression, etc. were not only affected psychologically but also at deep physiological levels which we have reaped today. As distressing as that can be, the wonder of it all is how our bodies have tried to adapt and continue to do so if given proper tools. Proper nutrition, vitamins, exercise and appropriate medicines can assist with the healing process. Yes, the extent of the long term damage must be noted but it is encouraging to know people still stand a fighting chance.
It is obvious from reading this book that Dr. Rocio Salas-Whalen MD board-certified endocrinologist, obesity medicine specialist is passionate about helping those who need it. ‘Weightless’ definitely provides a bounty of ‘science, clarity and confidence’ to explore weight loss options. I totally recommend this eye-opening, compassionate and empowering guidebook to doctors and patients (current and upcoming) alike. It certainly delivers an uplifting and positive path to wellness and will surely help those who need answers and guidance. 5 Stars ⭐️⭐️⭐️⭐️⭐️

One of the most helpful, informative books that I have read all year! I admit it, due to several personal injuries, health issues, and just plain laziness, I found myself quite a bit overweight. I've tried all kinds of diets, all kinds of exercises, and really not succeeded to the point I was satisfied. Then along came the "miracle drugs" of GLP-1 medications. I watched the television ads where all these celebrities have had incredible weight loss while using the drugs. I was bombarded with social media ads offering reduced rate subscriptions to the medication. And I have had friends that have lost a great deal of weight while on the drugs.
Somehow, I was still hesitant (chicken) to ask my doctor about the medication. I am old enough to remember when "Fen-Fen" was the supposed miracle weight loss drug. And what happened to the hearts of people who took it.
Then, in my annual visit with my cardiologist, he recommended Zepbound to me. Said he had been on it for six months and felt better than ever. I literally trust that man with my life, as he has already saved it once. So off I went to my primary care doctor to inquire about getting a prescription. "Sure, no problem" was the response. A short explanation of what to do, and out the door I went. That's the problem with today's medical industry, the poor doctor's are so rushed that they are only allowed a 15 minute visit with the patient. Hardly enough time to discuss all of the ramifications of the medication, and what to expect.
Still, I began the medication, and it has worked immensely! I'm down 35 pounds, with another 15 to hopefully lose. I was still left with a lingering uncertainty, of what was happening, what was the reasons, and what else was available.
AND THEN CAME ALONG THIS BOOK! I'm so happy that I was granted an ARC from NetGalley. I read the entire book the next day, and then again two days later. It is one of the most informative books that I have ever read.
The author is fortunate enough to be able to run a private medical practice, where she has the time and patience to thoroughly explain the who, what, where and how of how GLP-1 drugs work. Oh, how I wish I could find a doctor like her! So she had done the next best thing, and written down the information she shares with her patients. Clearly, informatively, and no fluff or fillers. Easily understood, it's as if she were sitting next to you explaining everything you wanted to know.
Thanks to this book, I am now very, very confident in my weight loss journey. I know exactly what's happening, and what to expect in both the short term and long term. AND...what is coming next in the GLP-1 medications, and how exciting the new batch will be!
It's not often that I can say that a book has physically and mentally changed my life for the better, but in this case, it definitely has!
Get this book and start living your life again!

I wasn’t expecting much from this book as I suspected that this author might be cashing into the hype around weight loss jabs but I was really pleasantly surprised. It was well written, considered and sensible and covered all the elements of the journey, including psychological adjustments you need to make. I am not taking the medication but I found there were also interesting tips in there for everyone. I think this would be a really good read for anyone thinking about it. Thanks to NetGalley and Rodale Books for the ARC.
Review of advance copy received from Netgalley
▹TL;DR Review: As someone who’s been on a GLP-1 for over a year, I found this book to be a great tool for not only reading about maintenance but would have been helpful to read prior to starting my journey. If you or someone you know is thinking about starting a GLP-1 journey, I recommend starting with this and talking with your doctor to see if it’s a good fit for you. ♥

○★○ What to Expect from This Book: ○★○
– About: Focuses on the medically grounded science, practical use, and real-life examples of GLP-1 medications for weight loss and improved health. Reframes obesity and weight management as a chronic health issue vs. a moral or willpower problem. This book is informative for readers who need help with choosing providers, understanding the effects of each medication, what to expect for results and what is expected from the patient both during and after treatment.
– Tropes: self-help, education on GLP-1, compassionate medical navigation, evidence-based strategies
– Representation: for patients who have gone to the doctor and have been told to “lose weight,” I see you. You are not the problem. This book will help reframe obesity and weight management so you can start your healing journey.

🎯 My Thoughts:
Before sharing my thoughts on this book, I want to offer some brief context so readers understand my perspective:
I’ve lived in a larger body for most of my life and have experienced weight stigma in medical settings, relationships, and everyday life. Like many others, I’ve cycled through countless diets with temporary results. I’ve also been on a GLP-1 medication for about a year and a half, which has significantly changed both my physical health and my relationship with my body.
This background naturally shapes how I approached Weightless, but I believe the book has value regardless of where you currently stand on weight-loss medication.
What stood out most to me is how comprehensive and grounded the book feels. Dr. Salas-Whalen begins by outlining the history and medical purpose of GLP-1 medications, how their use has evolved, and who may benefit from them. She also provides practical guidance on finding knowledgeable providers and navigating care—an aspect that many people struggle with but that’s rarely addressed clearly.
The book goes beyond medication alone, focusing on how to use GLP-1s responsibly and sustainably, including what to expect as you approach maintenance or long-term goals. I appreciated that it doesn’t frame these medications as a quick fix, but rather as one tool within a broader health journey.
Most meaningful to me was the attention given to the emotional and social realities of weight loss and the stigma surrounding these medications. The tone throughout is compassionate, nonjudgmental, and practical. Rather than reinforcing shame, the book reframes obesity through a medical lens and acknowledges how deeply personal and complex these experiences can be. That approach made me feel seen in a way few health books (or doctors) have.
The author also addresses accessibility and cost, openly acknowledging that GLP-1 medications aren’t financially available to everyone. She offers alternative strategies and supportive suggestions for readers who may not be able to pursue this option right now, which felt thoughtful and inclusive.
One area I wished had been explored more:
While the book does touch on the mental and emotional changes that can accompany weight loss, I would have appreciated a deeper discussion of the potential psychological side effects of GLP-1 medications themselves—particularly for individuals with a history of disordered eating. This may be an area where more research is still emerging, but given how closely weight, food, and mental health are intertwined, it felt like an opportunity for further exploration.
Overall, Weightless offers a compassionate, evidence-based perspective that challenges long-standing narratives around weight and health. Whether or not GLP-1s are part of your own journey, this book provides valuable insight into the science, the stigma, and the human experience surrounding them.
Some of my favorite quotes:

╰┈➤ ❝I watched the tension in his shoulders ease as his emotional burden was lifted. He started to cry. For the first time, he heard that he hadn’t failed. He felt the validation that what he was up against wasn’t a personal flaw but a medical condition.❞
(about one of the author’s patients after he came to her for help with his obesity)
╰┈➤ ❝One of the most revolutionary things about GLP-1 medications is that they make weight loss feel more natural. For many people, that means no more crash diets, no more white knuckling through hunger, and no more obsessing over every bite…That’s because they don’t just reduce appetite; they recalibrate the entire system that used to drive overeating in the first place.❞
╰┈➤ ❝Everyone involved needs to understand that this is not cosmetic weight loss; the goal is not simply to “get thin” but to reduce long-term health risks and improve quality of life.❞

I think this books stands alone on this subject in a number of areas, and while that is praise for what it is, it is also an indictment of the system, the status quo, the indifferent medical professionals, body shamers, internet keyboard warriors who have made obesity and weight loss a personal failure. It is, instead, a medical condition, something Dr. Salas-Whalen embraces and, if I may take liberties, evangelize.
My skeptic brain goes into overdrive when I see books that use definitive articles - “The” solution to your problems (one size does not fit all; you have more credibility if you say “a” possible solution is…), exclusive book selling lists - the four quadrants, the ten things you need to do (those usually tie to the definitive articles), or hyperbole - “miracle drug”, “groundbreaking”, “revolutionary”, “the secrets no one tells you”.
That’s not what happens here. Dr. Salas-Whalen is obviously a cheerleader and advocate for the medications she describes here, but she only used the word “revolutionary” four times (and “miracle drug” only once in the Introduction as a side eye to doctors prescribing it without helping patients with the holistic treatment). It’s not the theme, though. Talking the reader through as much as practicable on the subject is the theme. She says:
“I can't tell you how happy I am that you picked up this book. This means that you're on a GLP-1 medication, you are a family member or friend of someone taking one, or you might be considering using one for weight management.”
I am in the middle group - family member (though it is GLP-2, not -1, but the principles of before, during and after are the same). And I requested and received a review copy of this from the publisher through NetGalley to learn more.
Dr. Salas-Whalen establishes from the start that she understands. “Being skinny is not the goal. Losing fat is the goal. Improving your health meaningfully is the goal..” She says,
“Throughout this book, you'll notice that I use person-first language when referring to people with obesity or related health conditions. That means you'll see phrases such as "a patient with obesity" instead of "an obese patient" and "a person with overweight" instead of "an overweight person." This isn't just a matter of semantics. It's very important to me always to frame obesity as a medical condition, never as a personal failing or defining trait. Language matters, and how we talk about health can shape how we think about it. When we put the person before the diagnosis, we're not blaming the patient;…”
This is good. Much like “person with autism”, this is the language we all need to use, and then we all need to understand why it needs to be used.
She had the credentials and the experience and she knows how important is is to talk to, understand, connect with patients. She know “We [doctors] are set up to fail as physicians when we are not given the freedom to practice medicine as we see fit.” Meaning, when an office manager dictates the time allowed, physicians don’t have time to get the big picture… and may be going in a rote (and possibly wrong) direction when it comes to diagnosis and treatment.
This is an easy read. Yes she goes into the science. Yes she talks about studies. And more importantly, she makes the information accessible. From making it clear this is a medical not mental issue, to the background of the medications- history, mechanisms, effects and possible side effects, to what’s happening under the medication, what you need to do while taking it, emphasis on on taking in protein to prevent losing muscle mass with the fat (someone commented that they wished Dr. S-W had focused on protein… I think she did, with constructive repetition to reinforce the importance), dosages, post goal attainment habits. Interspersed with short testimonials, which may bother some with tethering inclusion, while for others they may serve as inspiration or identification - “Hey! That’s me!”
And that this is a medication (I have deliberately not used the term “drug” to not trigger any adverse impression to treat a condition not unlike high cholesterol or blood pressure: it can be safely taken as a maintenance dose for life. And there is no shame in doing so. I have been on statins for decades for my cholesterol. At first I thought my eating habits were at fault, but that didn’t prove to be the case, so… lifetime maintenance without guilt. Neither should there be with taking a GLP-1 medication, and I think Dr. Salas-Whalen has done a good job here conveying that.
And if you’ve read this far, you should so know that the healthy lifestyle promoted here is also good for folks not on one of these medications. Protein, exercise, mindful awareness of body composition… you get it.

Review of advance copy received from Netgalley
Rating: 4.25
Summary: For someone who is considering or just starting to take a GLP-1, or who has a family member who is, this book would be a great foundational guide to use as a handbook through the journey. It was an easy-to-read yet comprehensive book, and the author Dr. Rocio Salas-Whalen shares scientific support, as well as applicable anecdotes and wisdom, from her numerous years of experience with prescribing GLP-1s and briefly using them herself.
How the book is structured/main topics:
The book is broken into three main sections. The first four chapters outlines factors that may lead to obesity and how the medications work. It helps the reader appreciate the comprehensive number of factors that can lead to obesity, provides a history of GLP-1s, and thoughts to help readers decide how to evaluate if GLP-1s are the right choice and options on where to get it prescribed.
Chapters 5 to 7 focus on taking the medication, such as starting doses and when to titrate higher, considerations on what day to dose, and the importance of prioritizing protein and strength training to maintain muscle. It also covers side effects and adjusting dosages.
The final two chapters covers what happens after you’ve reached your goal for body recomposition. Dr. Salas-Whalen explains the options for titration down to a lower dose or even going off the medication if necessary, but the emphasis is that obesity is a chronic condition and many will likely require some type of maintenance dose. It also discusses the mental and emotional adjustments, not just physical ones, which people face with weight loss and changes in their health.
There are also a few quick reference sheets for protein and for appointment checklists to guide prep to converse with your prescribing medical professional.
Additional thoughts:
As someone who has done a fair amount of online research on GLP-1s, the book echoed many of the same points with which I was familiar. The author’s tone seems friendly yet professional, and while she shares many factors that may contribute to an individual’s obesity, it didn’t come across as judgment or subtly snarky. I would have appreciated having this book a year ago when I was having conversations with my primary doctor about starting a GLP-1 med; having a one-stop resource at home to kick things off would have been useful. I have been taking tirzepatide pen injections for almost a year now, and I have experienced some common side effects, as well as several less common ones, although none have been serious enough that I needed to discontinue the medication. I thought it was important how much she emphasized the need to maintain adequate protein because it is difficult, and she provided sample menus on how to achieve such. It’s great to be prepared and know the history of the meds, but actually taking the medication can be quite an adjustment for many people. More depth on troubleshooting side effects would be useful—it’s covered, but side effects can be detailers that make people feel like quitting early so having more on that topic seems like it would be welcomed by many. Also, for those with more to lose, my perception is that there can be many more plateaus or adjustments needed, partly due to the longer duration. I felt like it took a lot of trial and error and know that I am not alone in feeling that way.
Overall, the book is a solid guide, and I will recommend it or gift it to others who are early in their journey. Thank you to Netgalley, the author, and Rodale Books for the ARC. All opinions are my own.

Review of advance copy received from Netgalley
This book was a must read for anyone struggling with their weight and considering taking any weight loss drugs.
The author starts with apologizing to all obese patients who she told to stop eating and exercise and they would lose weight. She said that obesity is a disease and not a matter of willpower.
She then went on to describe the many factors that cause the disease of obesity: genes and environment, hormones, life stages, emotions, endocrine disrupting chemicals in plastics and personal care products, medications, lack of sleep, stress, and metabolic slowdown as we age due to muscle loss, lower protein intake and reduced physical activity.
Stories of her patient’s journeys were also helpful to emphasize how obesity is a disease and is so hard to control.
Metrics for health and weight management were thoroughly explained including fat measurement, lipid profiles and inflammatory markers.
The thorough review of the history of GLP-1 medications was eye-opening to me because it made me realize how long these drugs have been used successfully and how they have been improved over the years. A comparison explanation of FDA approved medications versus compounded medications was important to know for the safety of anyone considering taking these drugs. Explanations of the different generations of these drugs and how they work was extremely informative.
Questions to ask when looking for a provider for your GLP-1 journey, what to expect when you start, how to monitor progress, and even storing the medications was thoroughly discussed.
Guiding the patient to optimal results was explored. She described the importance of preserving muscle to help burn fat by eating enough protein and strength training. She went into detail about the composition of protein, what constitutes a complete amino acid and a nonessential amino acid. She even included sample menus to ensure you eat enough protein.
She went over what to do once you hit your goal weight; decreasing dosages vs getting off the drug completely. Psychological effects of large weight loss including how to handle positive as well as negative comments, and excess skin loss was described as an important part of the journey that must be considered.
This book is an invaluable resource for everyone to understand the disease of obesity and how these drugs help control it. It is written in such a way that ANYONE can understand it. This is so important so people without a science background can understand these drugs and make informed decisions when considering starting this journey to better health.
I highly recommend this book for all people, not just obese people, so obesity can lose its stigma and people will be less judgmental and more compassionate towards people with this disease.
I thank Netgalley and the publisher for giving me the privilege to read an advanced reader copy of this outstanding book. I am writing this review honestly and voluntarily.

✨ ARC REVIEW ✨
TITLE: Weightless
AUTHOR: Dr. Rocio Salas-Whalen
PUBLICATION DATE: Dec 29, 2025
PUBLISHER: Rodale Books
RATING: ⭐️⭐️⭐️⭐️⭐️
Dr. Salas-Whalen, a board-certified endocrinologist, delivers a groundbreaking guide to GLP-1 medications—Ozempic, Wegovy, Mounjaro, and Zepbound—and reframes obesity as a chronic, biologically driven condition rather than a personal failure. The book breaks down the science in an accessible, judgment-free way, explaining what these medications do inside the body, who they’re appropriate for, and how to use them safely.
The focus is on reversing obesity with evidence-based tools, not quick fixes. The tone feels supportive and practical, giving readers the confidence to advocate for themselves and understand their options in a medical landscape that can feel overwhelming. I also appreciated the emphasis on reducing shame, cutting through misinformation, and helping readers make informed decisions about their health.
💡 What makes this book stand out:
— The GPS protocol: GLP-1 + Protein + Strength training, designed to protect muscle and metabolism while losing fat.
— Myth-busting clarity: From “Ozempic face” to viral misconceptions, she dismantles hype with science.
— Emotional ripple effects: How weight loss shifts relationships, identity, and self-image—and how to navigate those changes with compassion.
— Midlife resonance: Insight into perimenopause and menopause, explaining why traditional diets often fail and how GLP-1s can help.
— Patient stories: Real voices that make the science personal, showing both triumphs and challenges.
This isn’t a quick-fix manual—it’s science, strategy, and soul. Salas-Whalen’s tone is warm, direct, and deeply respectful, offering readers a roadmap to reclaim their health with clarity and confidence.
If you’re exploring GLP-1 meds or simply want a trustworthy, medically grounded resource in a topic full of noise, Weightless is absolutely worth keeping on your radar.
Thank you to NetGalley, Dr. Rocio Salas-Whalen, and Rodale Books for the ARC.

Review of advance copy received from Netgalley
I requested and received an author's review copy from Netgalley with deep interest as I had just begun a GLP1 regimen and was curious about a deeper perspective, one the book handily delivered.
This book is a student's look at what some call a cosmetic regimen while others, those for whom the drug was intended, are finding it to be a lifesaver. The practicing physician's viewpoint in this book is informed, detailed, customized for its audience, and doesn't shy from discussing perspectives. The book begins with the requisite long-term history of any drug, including the various forms of GLP-1 prescriptions available in the market. The earliest variants and their results, side-effects, and patient perspectives are discussed just as the author moves into the present day. The book moves into discussing obesity, not as a physical condition but a mental, medical, and lifelong medical diagnosis with potential for intervention. It moves through removing guilt and replacing it with prescriptive therapy.
The GLP-1s role is discussed in how it impacts metabolism and lifestyle, along with the catalysts that make GLP1s more effective. From such simple areas as changes brought about in appetite, sleep, gastric reactions, muscle, and skin. The author-physician delivers a masterful pre, during, and post weight-loss timeline of therapy, complementing the drug's impacts with requisite changes in protein intake and strength training. She doesn't just lecture about the protein and strength topics, choosing instead to discuss why each is important, the changes each affects, and the cost of avoidance.
I found the book incredibly insightful, despite prior knowledge of the topic gained before I started my own regimen. It is a comprehensive volume that dispenses with high volumes of medical jargon, eschews lecture for lesson, and informs just as it inspires. I believe it will be a must-read for those considering GLP1s or supporting those who have adopted the regimen.

Review of advance copy received from Publisher
As someone who has had an up-and-down journey with my weight over the years, I am generally curious about the latest/greatest/whatever guaranteed way to lose weight…and have known several people who have been or are taking one of the GLP-1 products (Wegovy, Mounjaro, Ozempic, whatever). But for me it has been sort of like AI: I don’t really understand how it works or what the implications are for users…is it something that will truly change your life? Is it something that will need to be used FOREVER?
I was pleased to read about a book by Dr. Rocio Salas-Whalen, a board-certified endocrinologist and expert in obesity medicine about these “wonder drugs,” and thanks to Rodale Books and NetGalley, I received a copy of Dr. Salas-Whalen’s book Weightless in exchange for this honest review.
She is a physician who views obesity as a chronic health condition rather than a failing or lack of will power/character/effort on the part of the patient/client. Her focus in the book is being as healthy as you can be, choosing the right product and clinician, preserving muscle while losing, and generally having a good and healthy life at whatever weight you might be.
I still don’t understand GLP-1, and TBH it still scares the crap out of me. Oh, and there is STILL a tiny bit of my brain that believes that the only healthy way is the one that worked for me over the years: eating well and exercising. (Of course, now that I have two different kinds of cancer, my entire thought process about health is somewhat askew, but that’s another story)
Overall, this book is recommended with the caveat that the most important element in weight loss success is a solid relationship with an ethical, knowledgeable physician who will LISTEN and help patients (in addition to selling a product and promising miracles). Four stars.

Dr. Salas-Whalen is an endocrinologist and trained in obesity medicine. The book gives us a background on how the body works to maintain weight and metabolize food, and all the hormones involved within the process. There are many things that can interfere with the process, whether it's medications, hormonal changes from age and muscle loss, to the additives in American foods designed to keep us hungry and eating more. The GLP-1 medications are more and more common, but there are doctors prescribing it without any explanation to patients on what to expect and how to maintain its benefits after stopping the medication.
As a guide for those interested in GLP-1 medication, this is written in a clear, factual manner putting the medical information into everyday English for the average person to understand. The complicated history of their development and the research behind it is explained to give it the full weight and explanation as to how it works and why doctors trust in these medications. Better than that, Dr. Salas-Whalen goes through what to look for in a doctor who would prescribe these medications, what questions to ask regarding tracking progress, and what to expect from treatment. She even has tips for how to make the most of telemedicine if you're rural and don't have access to specialists.
The importance of medication is one thing, but I like how she stresses protein intake and exercise as necessary components to this. Many doctors don't do this at all, and don't take the measurements or labs that she does. She outlines common side effects that can be expected and what to do about them, physical changes, and even scripts on discussing weight and the use of meds with others asking about it.

Weightless offers an encouraging and judgment free look at GLP-1 medications and the evolving landscape of obesity treatment. Dr. Salas Whalen’s background as an endocrinologist and obesity medicine specialist gives her writing authority, and she communicates the science in a way that is easy to take in. Her approach is rooted in empathy and practicality, which is refreshing in a genre that often leans heavily on shame based messaging.
The book covers the basics clearly. Readers will learn how these medications work, what early expectations should look like, how to select a knowledgeable provider, and how to maintain muscle and overall health throughout the process. For someone brand new to GLP-1 medications, this structure is helpful and grounding. It answers many of the questions beginners usually have but are unsure how to ask.
Where the book fell short for me is in its lack of new material. I have been reading GLP-1 related books for the last couple of years, and little in this one surprised me or pushed beyond the foundational information that is already widely available. Readers who are already familiar with this health topic may feel the same. The pacing also feels a bit slow in places which makes the repetition more noticeable.
This is not to say the book is without value. It would make a strong first read for someone just beginning to explore GLP-1 medications or feeling overwhelmed by conflicting information online. Dr. Salas Whalen provides reassurance and structure, and sometimes that is exactly what a reader needs. For those already deep into GLP-1 research, this book may serve more as a refresher than a guide.

December 1, 2025
"Weightless" by Rocio Salas-Whalen genuinely surprised me. With so many people around me taking GLP-1 medication, I figured I should explore the science behind it—but I was sceptical and didn’t expect to find much of use. Boy, was I wrong. The author offers a thorough, clear overview of the biology of obesity and the physiology of GLP-1 drugs - I found the section on the history of these medications particularly fascinating.
The book excels in practical guidance, covering everything from starting treatment, through considerations during use and managing life after reaching your goals. Case vignettes break up the information nicely, making it very readable. What really stood out was the author's authentic voice and depth of experience. It feels like the book is written by someone who has genuinely guided people through this complex journey, rather than just hopping on a trend with a quick guide based on a surface-level literature scan.
I’m not based in the US and though some sections, e.g. on finding providers or sourcing the medication, are very country-specific, I feel most parts are still valuable as a thought framework. Even without access to multiple dexa scans or obesity specialists, working through the included pre-visit checklists and questionnaires by oneself can focus the mind and prepare for a more meaningful discussions with available service providers.
I would definitely recommend this book to anyone navigating the GLP-1 treatment path. It offers both science and pragmatic practicality, grounded in real-world insight.

Weightless is a very thorough and genuinely helpful book about GLP-1 medications. I expected a general overview, but what Dr. Salas-Whalen delivers is a clear, science-backed guide that actually explains how these medications work, why they exist, and what the whole journey can look like—physically, psychologically, and practically.
What I appreciated most is how grounded the information is (especially as someone who works in the healthcare and regulatory landscape). She talks through the history of GLP-1s, the biology behind obesity, and the mechanisms of the medications in a way that’s both accessible and incredibly well-referenced. The citations alone make this a standout resource for anyone who wants to understand the “why” behind their treatment.
The book also goes far beyond just the science. There’s helpful guidance on side effects, managing expectations, talking with your doctor, and what success can actually look like. Overall, I believe one of the most notable aspects of this book is the author’s clinical experience and empathy. The case examples, the practical advice, and the nonjudgmental tone make this feel like a conversation with someone who has walked many patients through this process and understands how complicated it can be. Whether you’re considering GLP-1 therapy, are already on it, or simply want a well-researched, stigma-free look at the topic, Weightless is absolutely worth reading. It is both scientifically rigorous and genuinely supportive!

Review of advance copy received from Netgalley
I cannot recommend Weightless highly enough. Of all the GLP-1 books I have read recently, this is the best.
If you are thinking about starting a GLP-1 like Ozempic, Mounjaro or their compounded equivalent, you need to read Weightless first. It reads as if your best friend just happens to be a weight loss doctor. She answers all your questions clearly and honestly. She even answers some questions that you haven’t even thought of yet.
Most doctors, and certainly most compounding clinic staff, do not really explain what happens when you take these drugs. You are kind of left on your own to figure it out through trial and error or the AI slop filled internet, which is pretty frightening really. This book includes chapters relating to each step of your GLP-1 journey from side effects to tapering off after your weight loss goal is reached. It is comforting to know that you are not floundering about out there on your own. You have an expert by your side.
With the new price reductions in the cost of this drugs on the horizon, now is the perfect time to get familiar with how these drugs can help in your weight loss journey. You still have to do the work of reducing your food intake, boosting your protein, and using strength training to reduce muscle loss. However, now you can do it with no more food cravings and a smaller appetite. Taking Weightless along will make you a much more knowledgeable consumer of these drugs benefits and costs. 5 stars and a favorite.

Weightless is described as “A Doctor's Guide to GLP-1 Medications, Sustainable Weight Loss, and the Health You Deserve.” Written by a board-certified physician who specializes in obesity medicine and endocrinology, this book will answer many of your questions as you begin your GLP-1 weight loss journey, provide guidance while you are on the journey and help you navigate the challenges once you have stopped taking a GLP-1 medication.
The book is divided into three main sections: what to expect and how to prepare before you start taking the medication, how to proceed and what to do to maximize weight loss and maintain your overall health while taking it, and what steps to take to ensure the weight stays off and you remain healthy when you stop taking a GLP-1. In addition, the author shows how the medical community view of obesity has changed over recent years, shifting blame and guilt away from the patient and recognizing obesity is a medical condition to be treated like any other.
Author Rocio Salas-Whalen dives deeper into the use of GLP-1s than the always happy, no effort required on your part myths of television commercials and popular culture. The subject of obesity and weight loss using a GLP-1 is presented with care and compassion as well as sufficient detail and planning aids that may not always be provided by your doctor or the product literature.
I received an advance copy of Weightless from NetGalley. It’s easy to read, down to earth and a useful resource. I voluntarily leave this review; all opinions are my own.

Thank you to Rodale Books and NetGalley for the opportunity to read an advance readers copy of Weightless by Dr. Rocio Salas-Whalen. All opinions are my own.
GLP-1 medications are all over the news these days and for a good reason. They are helping a LOT of people get to a more healthy weight - including ME. Because of my experiences with this type of medicine, I was quite interested to read Weightless by Dr. Salas-Whalen. She is a specialist in endocrinology and has been treating patients with obesity for years, so she seemed likely to be a good source of valuable information.
Weightless is an excellent overview of the use of GLP-1 medications, with advice on how to start, what to expect, what to do once you've reached your goal weight, etc. Dr. Salas-Whalen writes in a conversational style and you can just tell that she has a great “bedside manner” and compassion for her patients.
Her writing is clear and not overly technical. Because I’m now at a weight that I want to be at, I was particularly interested in the sections on what to do once you reach your goal weight. The sections on getting enough protein (something I totally struggle with!) and strength training were both informative and important. There’s even a “protein cheat sheet” which will help people figure out what to eat to reach their protein goals.
I recommend this book for anyone interested in finding out more about this relatively new class of medications.

Review of advance copy received from Netgalley
This is a very informative and timely book as the use of GLP-1 drugs increases. The author gives a great deal of information from the creation and studying of these drugs (over 2 decades of research!) to the product differences without requiring us to also have a MD license to understand the information. The book is meant to support those looking to use GLP1s for weight related issues - specifically, obesity. The author is cautious about describing the potential causes of obesity to avoid guilt and shame in those with the problem. The author is never judgemental, encouraging in terminology, supportive and positive.
Also shared in this book are dosages, how to start the drugs, monitor the effectiveness, talk with your doctor, manage potential side effects and maintain long term success. The acronym of GPS (GlP- 1, protein, strength training) is well explained and defended to the long term success for anyone on this type of medication. Protein sources were simple and easy to obtain without a great deal of cost.
Overall this was an interesting read and I can see the book being used as a guide during someone's journey on these drugs. Chapters about troubleshooting or talking with your doctor could be referenced as the need arises and used as a manual.

Review of advance copy received from Netgalley
I requested this ARC because, like so many people right now, I’m absolutely fascinated by GLP-1 medications. What are they really doing inside the body? How much do we actually know about their long term effects? And are they truly as groundbreaking as the headlines suggest? I had a million questions, and Dr. Rocio Salas-Whalen answered every single one, and then some.
What makes this book so effective is Dr. Salas-Whalen’s ability to break down complex science into clear, relatable explanations without ever talking down to the reader. She weaves in personal stories and patient experiences that bring humanity and nuance to a topic that is often sensationalized or oversimplified. Weightless is packed with evidence based information, thoughtful insight, and practical guidance. I came away not only better informed but genuinely impressed by how accessible and compassionate this book is.
If you’re even remotely curious about GLP-1s, whether for yourself, a loved one, or simply to understand the cultural moment, this is an invaluable read. I learned so much, and I highly recommend it.

Review of advance copy received from Netgalley
This book was an interesting read for me as I have Type 2 Diabetes and am currently taking a GLP-1 medication (Ozempic). Dr. Salas-Whalen does a great job of attacking the stigma around GLP-1 medication usage for those using it for weight loss. I find it extremely useful that she included questions to ask your healthcare provider and a protein cheat sheet, especially because these are likely what will be referred to by readers the most after the initial read of the book.
The part about "after" is meant to be read once you have achieved your weight loss goals; if you haven't, it feels awkward to read her congratulations. Otherwise, it gives helpful insight into what you might see in your future once you reach those goals.
While I am not on this medication for weight loss, this book has impacted my view on GLP-1 medications and made me more empathetic to those who use it for weight loss. Obesity is a serious chronic medical condition, and I didn't realize how impactful it can be for those experiencing it to use these medications.
I would recommend this book to anyone on GLP-1 medications or who is considering them, even a little bit. It is well-informed and addresses many myths about GLP-1 use.

Review of advance copy received from Netgalley
Two of my family members have shown amazing results from using a GLP-1 (glucagon-like peptide-1) drug. I knew nothing about it so jumped at the opportunity to read and review this book. I was surprised to find that GLP-1 refers to a hormone found in the body naturally, produced in the small intestine. It is short lived, however, so a form of it needed to be developed to be of good use in weight loss. Salas-Whalen provides the history and the science in a very clear way. She helped me understand the use, the possible side effects, the necessity for eating enough protein, and the lifestyle changes that come with it, such as learning to live with the new version of your body.
I have learned a great deal about obesity in general too. I was taught it was a will power problem but now I know it is much more complex. It is really a medical condition and using GLP-1 medications is like using blood pressure medication for that condition.
This book contains everything one would need to know to have the best experience with this form of medication.
I received a complimentary egalley of this book from the publisher. My comments are an independent and honest review.

Weightless offers a genuinely useful, accessible introduction to GLP-1s. The advice is simple, practical, and easy to follow. I came away with a much clearer understanding of how GLP-1s work, their history, and the broader context around obesity. I especially appreciated the emphasis on protein: why it matters, how to incorporate it, and what to expect when starting medication. The book also covers why strength training is important, though I found that section less detailed.
The protein cheat sheet was a standout: concise, actionable, and genuinely helpful. I wish there had been something similar for strength training. While it touched on frequency and volume, it lacked the same clarity around specific exercises or routines.
This is absolutely a strong resource for anyone starting or currently using GLP-1s, especially in the US. That said, quite a few chapters weren’t relevant for UK readers. Our healthcare systems differ significantly. So while those sections were interesting, they didn’t apply to my experience.
Thanks so much for the e-ARC.

I don’t usually reach for nonfiction in the medical sphere, but because this topic is personally relevant to me, I decided to give it a shot and I'm glad I did.
This book is incredibly well written and thorough. I didn't expect to fully graps everything as the author explains everything clearly leaving the reader feeling content.
You can tell the doctor behind this book genuinely cares about both the subject matter and his patients. That level of compassion is something I wish I witnessed more of.
The book does an excellent job differentiating common myths and misinformation surrounding GLP-1 medications. It also gives tips on how to optimize results, outlines what doesn’t work, and dives into both aftercare and what the future of these medications might look like. It feels comprehensive without being overwhelming.
Truly, whether you think you know about GLP-1s or you’re just beginning this is absolutely worth the read.
