Endocrinologist launches MasterClass on GLP-1 therapies and weight loss

SAN FRANCISCO, Sept. 3, 2026, Endocrinologist and obesity medicine specialist Dr. Rocio Salas-Whalen has launched a new class on MasterClass, an online learning platform, titled "Understanding GLP-1s and Weight Loss." The class, which is available exclusively on MasterClass, aims to educate patients on the science behind GLP-1 therapies and provide them with a comprehensive framework for managing their treatment.

According to a recent Gallup survey, 11% of U.S. adults are now taking GLP-1 medications for weight loss, up from just 3% two years ago. These medications, which include semaglutide and exenatide, are increasingly recognized by the public, with 91% of Americans familiar with them. Dr. Salas-Whalen, who has treated over 16 years of patients with GLP-1 therapies and was one of the early adopters in the U.S., believes that patients should have a thorough understanding of these drugs before starting treatment.

In her class, Dr. Salas-Whalen addresses common concerns among patients, including typical side effects, the reasons behind weight gain, preserving muscle mass, and the duration of treatment. "A GLP-1 is not a supplement or the latest diet trend," Dr. Salas-Whalen said. "It's a prescription medication designed to help people maintain their weight loss long-term. The guidance of the clinician is crucial."

Dr. Salas-Whalen shares her insights on managing side effects such as nausea and fatigue, explains the complex factors that influence weight gain, and offers advice on maintaining muscle mass during weight loss. She also provides guidance on dose management, emphasizing the importance of informed conversations between patients and healthcare providers.

"The experience and guidance of the clinician prescribing these medications matter a great deal," Dr. Salas-Whalen noted. "I built this class to give patients the knowledge they need to understand their treatment, ask better questions, and advocate for themselves. An informed patient is an empowered patient."

The class, available on MasterClass, is part of the platform's commitment to offering personalized learning experiences. MasterClass, which provides unlimited access to over 200 instructors and classes across various subjects, aims to empower individuals to achieve their potential through expert-led education.

MasterClass, the personalized learning platform unlocking human potential with the world's best instructors, continues to expand its offerings to meet the needs of a growing number of patients and healthcare professionals. Through advanced learning experiences like "Understanding GLP-1s and Weight Loss," MasterClass aims to bridge the gap between medical science and patient understanding.
