New York, NY — December 30, 2025 — Weightless: The Science Behind GLP-1s and Your Metabolism (Penguin Random House / Rodale, Dec 30 2025) by triple board-certified endocrinologist Dr. Rocío Salas-Whalen has received a starred review from Publishers Weekly, the highest distinction awarded by the industry’s most influential book review publication.
The Publishers Weekly star is reserved for “books of exceptional merit,” recognizing Weightless as a standout title in the rapidly evolving field of metabolic and hormonal health.
In Weightless, Dr. Salas-Whalen reframes the conversation around obesity, hormones, and GLP-1 medications — shifting it from willpower to science, from shame to empowerment. Drawing from over a decade of clinical experience and personal insight, she offers a compassionate, evidence-based roadmap for lasting change.
“This recognition means the world to me,” says Dr. Salas-Whalen. “Weightless was born from years of listening to my patients — their struggles, their hope, their strength. I wanted to create a guide that educates, empowers, and uplifts. To see it recognized at this level is deeply meaningful.”
Weightless will be published in the U.S. on December 30, 2025, with global editions in 2026 (UK/AUS/India/South Africa via Ebury and Spanish/Latin America via EDAF).
