GLP-1 medications like Ozempic, Wegovy and Mounjaro have transformed the weight-loss conversation and demand for clear, credible information has exploded. There are still few good books written specifically about the drugs, so this list pairs the best doctor-authored GLP-1 guide with the metabolic-science books that explain why these medications work and how to use them well, from protecting muscle to eating for long-term health. Every author is a physician or scientist.
This is medically serious: these are books, not medical advice and GLP-1 drugs are prescription medications with real risks and benefits. Never start, stop, or change any medication based on a book. Talk to your doctor.

We hold to a simple rule: if we cannot verify an author's credential (MD, PhD, RD, DPT, PsyD, or licensed clinician) from a publisher or university bio in about two minutes, the book does not make the list, with clearly labeled exceptions for a few excellent journalist-authored titles. No cure-all claims, no anti-science, no wellness influencers. We describe and compare these books to help you choose; we do not reproduce their contents.
Please note: these are books, not medical advice. Everyone's health is different. For your specific situation, talk to your doctor before acting on anything you read.
