NATIONAL BESTSELLER • A board-certified physician shares her must-have guide to using GLP-1 medications, such as Ozempic, Wegovy, Mounjaro, and Zepbound, to reverse obesity and take charge of your health, with established strategies for maximizing your results

“This book is a game-changer. Dr. Salas-Whalen gives you the science and the compassion this conversation has been missing. You are not alone anymore.”—Mel Robbins, #1 New York Times bestselling author of The Let Them Theory

Whether your struggle to lose weight has lasted years or started more recently, GLP-1 medications will help you finally end it. While GLP-1s have redefined how we treat obesity, the search for expert care is likely to leave you feeling confused, overwhelmed, and unheard. Misconceptions are everywhere. Many doctors are still catching up with the science. And you may find a prescription but not the medical supervision you need for the best results.

In Weightless, Dr. Rocio Salas-Whalen, an expert in obesity medicine, delivers the real-world strategies that have helped thousands of patients achieve health goals that once felt out of reach. Her deeply compassionate approach sees obesity, not as a personal failure but as a chronic health condition that deserves medical treatment. Drawing on years of clinical expertise and the lived experience of her patients, she explains how to:

• Rethink what you know about weight management: Learn why “eat less, move more” is an outdated and ineffective prescription.
• Give your GLP-1 journey a strong start: Choose an experienced provider, ask the right questions at every appointment, and get better outcomes if you’re using telehealth.
• Preserve muscle for long-term success: Follow Dr. Salas-Whalen’s advice for increasing protein intake and optimizing your strength training.
• Protect your progress: Manage side effects with evidence-based care, recognize when you need a dosage change, and know what to do when GLP-1s don’t work.
• Adjust to life after GLP-1s: Navigate the unexpected physical, social, and psychological changes that accompany significant weight loss.
  Comprehensive and empowering, Weightless offers judgment-free support that ensures you never feel alone on this journey.

Rethinking Obesity: What We Got Wrong

There is one patient consultation that has stayed with me over the years. The patient was fifty-one years old, successful in his career, polite, thoughtful—and clearly uneasy the moment he stepped into my office. When I asked what had brought him in, he explained that he had tried everything: dieting, fasting, overexercising. He had lost weight many times but always gained it back. He said, “I guess I’m just not trying hard enough, but I just don’t know what else to do.”

I shook my head and told him, “Obesity is not your fault.”

I explained what we now understand about obesity: that it’s not just about what you eat or how much you move; it’s about hormones, genetics, the brain, the gut, and many other factors outside of willpower. And then something unexpected happened. There was a visible shift; 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.

And I hadn’t even told him the best part yet: There was something we could do about it.

When I see a reaction like that, it makes me want to share everything I’ve learned about obesity with everyone—and repeat it over and over. In this chapter, you’ll learn what’s going on “behind the scenes of the body” and the reasons behind weight gain in cases like my patient’s—and maybe yours, even if you don’t identify with the term obesity.

Whether or not you’ve been formally diagnosed with obesity, this is a crucial chapter to help you understand your body and its treatment in a whole new way. If you’re someone with excess weight who is considering taking GLP-1 medication—or even just trying to better understand why your body holds on to weight despite all your efforts—read on.

In the pages ahead, we’ll pull back the curtain on what obesity actually is: not a character flaw but a disease influenced by many aspects of our biology and environment. I share this information not to lecture you but to make your experience with GLP-1 therapy more effective, more comprehensive, and ultimately more empowering. I want you to understand that this treatment is informed by real people and real life. Along the way, you’ll also begin to see the full picture of obesity—one grounded in science, not bias.

There’s much to learn ahead, but just as important, there’s much to unlearn.

Understanding Obesity

In medicine, there is a commonly accepted idea that within the patient/doctor dynamic, it is only the patient who needs to learn. This couldn’t be further from the truth, and I am proof of this. In my opinion, a physician who is not learning is a physician who is not listening to their patients.

For decades, medical professionals have been taught to approach obesity as a simple math problem: Eat less, exercise more. This advice was repeated in exam rooms, public health campaigns, and weight loss programs. And because it was presented as a straightforward solution, it also carried an unspoken assumption: If a patient wasn’t losing weight, it must have been due to a lack of effort, discipline, or willpower.

But if this approach truly worked, why did obesity rates continue to rise? Why do millions of people—many of whom have followed every diet, exercise plan, and medical recommendation—still find themselves struggling with their weight? The answer: It’s not because patients aren’t trying but because this approach to treating obesity is fundamentally flawed.

To fully grasp the scope of this issue, let’s step back and examine the bigger picture. The statistics on obesity tell a story—on…
