Weightless by Rocio Salas-Whalen Book Review

About the Book:

A board-certified endocrinologist 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, a board-certified endocrinologist and 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· Rethink what you know about weight management: Learn why “eat less, move more” is an outdated and ineffective prescription.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.

My Review:

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.

My rating: 4/5 stars.

This book releases December 30.
