Weightless

A Doctor’s Guide to Weight-Loss Medications, Sustainable Results and the Health You Deserve

  • Dr Rocio Salas-Whalen



An expert, fully informed approach to living on GLP-1s, from NY-based endocrinologist Dr Rocio Salas-Whalen

'This book is a game-changer. It says what too many people need to hear but rarely do: Struggling with your weight is not a personal failure... If you’ve ever felt isolated in this fight, you need to read this book. You are not alone any more.' – MEL ROBBINS, bestselling author of THE LET THEM THEORY

Your playbook for optimising results on GLP-1s, to reverse obesity and take charge of your health – including guidance on how to sustain weight loss once you come off the medication.

*With a foreword from New York Times bestselling author of THE NEW MENOPAUSE, Dr Mary Claire Haver*

GLP-1 medications have revolutionised how doctors treat obesity and changed the lives of the people who take them. With demand for these transformative drugs skyrocketing, people interested in trying GLP-1 therapy for weight loss are navigating uncharted landscape, and many patients walk out their doctor’s clinic with a prescription but not the essential guidance they need to get the best results – or sustain them.

In Weightless, Dr. Rocio Salas-Whalen, an obesity medicine specialist, covers this crucial information and the tried-and-true strategies that have helped her patients achieve their health goals. She helps you understand that taking your medication is only one step of the journey. In fact, these drugs work best when you pair them with proper monitoring and lifestyle changes. Drawing from her clinical experience and stories from her patients, she explains how to:

  • Ask the right questions at your first appointment and select the best GLP-1 medication for you
  • Understand how it will change your experience with food and hunger
  • Adopt the two other key 'prescriptions' – eating more protein and strength-training – to get the most from your treatment and prevent muscle loss
  • Navigate the impacts of GLP-1 therapy on your relationships with others, and yourself
  • How to sustain your weight loss when you come off GLP-1s
Comprehensive and research-backed, Weightless will give you the science, clarity, and confidence to take the first step toward a healthier, more empowered you.
