Most people still think GLP-1s are "weight loss shots," but what we are really doing is changing biology at the level of appetite and inflammation, with ripple effects across future generations. In this conversation, I sit down with endocrinologist and obesity specialist Dr. Rocio Salas Whalen to unpack what these medications do inside the body and how to use them responsibly as part of a long-term health strategy.

We get into why "eat less, exercise more" failed so many patients, how family history, hormones, and aging drive obesity, and why GLP-1s must be paired with protein and strength training. We also explore GLP-1's impact on visceral fat, diabetes, brain health, what healthy weight loss looks like on a body composition scan, and how to avoid sarcopenia and the so-called "Ozempic face."

Dr. Rocio Salas-Whalen is a board-certified endocrinologist and obesity-medicine specialist, author of Weightless, and an early adopter of GLP-1 therapies. Her so-called "GPS framework", GLP-1, protein, and strength training, reflects her approach to evidence-based obesity care.
