The most comprehensive GLP-1 book ever written. And it is not even close.

Written by a board-certified obesity medicine physician who takes tirzepatide himself, lost 80 pounds on it, and got tired of watching patients get bad guidance from providers who do not know these medications the way he does.

Why I wrote this book
Because I got tired of watching it happen. Patient after patient showing up in my clinic after months on a GLP-1 with no dose adjustments, no lab work, no nutrition plan, and no idea whether what they were experiencing was normal. Providers handing out prescriptions like candy and then disappearing. Patients Googling their side effects at midnight and getting answers that are flat-out wrong. I wrote this book because 5,000+ patients taught me that the medication works, but only when somebody actually teaches you how to use it.
Nothing like this exists. There are blog posts. There are Reddit threads. There are pamphlets your pharmacy staples to the bag. None of them come close. The GLP-1 Bible covers everything: the science behind how these medications work, every side effect and what to actually do about it, how to eat, how to train, how to protect your muscle mass, how to handle plateaus, how to navigate insurance, how to transition into maintenance, and dozens of topics most doctors never bring up. It is written for patients, not physicians, but it does not dumb anything down. You deserve to understand what is happening in your body and why.
I take tirzepatide myself. I have lost 80 pounds on it. Every chapter in this book is built from real clinical experience and grounded in current evidence, written by a physician who lives this alongside his patients.
