7 Reliable Experts to Follow for GLP-1 Advice

This probably isn’t news to you, but the internet—especially social media—can be a mess when it comes to GLP-1 information. There’s no shortage of information, but not all of it is accurate or trustworthy. The safest bet is still board-certified medical providers who work with these medications every day.

Below, we’ve rounded up seven experts worth following for clear, up-to-date GLP-1 guidance, from board-certified obesity medicine physicians to endocrinologists, plastic surgeons and more.

Rocio Salas-Whalen, MD is a New York–based, board-certified physician specializing in obesity medicine and endocrinology who’s especially good at making GLP-1s feel less confusing.

On social media, she talks about topics such as how these meds work for women, what changes with PCOS or insulin resistance and what to expect as treatment progresses. She regularly flags GLP-1 news as it happens, and explains what’s worth paying attention to (and what isn’t).

She’s also the author of Weightless, A Doctor’s Guide to GLP-1 Medications, Sustainable Weight Loss and the Health You Deserve.

Dr. Spencer Nadolsky is a board-certified obesity medicine physician who posts a lot about the day-to-day realities of GLP-1 use. He covers things patients actually ask about, such as dose changes, side effects, muscle loss, plateaus and what changes over time.

When misinformation starts circulating, he tends to address it head-on, explaining what holds up and what doesn’t without overcomplicating the science.

He’s also the author of The Fat Loss Prescription: The Nine-Step Plan to Losing Weight and Keeping It Off.

Amanda Kahn, MD is a New York–based, board-certified internist and longevity specialist who approaches GLP-1s through a long-term health lens. Instead of focusing solely on weight, she talks about energy levels, metabolic health, body composition and what long-term use of GLP-1 medications can realistically look like.

Johnny Franco, MD is a board-certified plastic surgeon who breaks down how weight loss can affect the face and body over time, including for people using GLP-1s. His posts often focus on things patients start noticing once the weight comes off—changes in volume, skin laxity and proportions—and how to think about next steps without rushing.

While most of board-certified facial plastic surgeon Kay Durairaj, MD’s content centers on aesthetic treatments—often offering a behind-the-scenes look at what patients can expect during appointments—she occasionally addresses the intersection of aesthetics and GLP-1 medications. When she does, it’s usually to explain terms like “Ozempic face” and other weight-loss–related facial changes, including shifts in volume or skin quality that can occur with rapid weight loss, as well as how those concerns are treated.

You’ll often hear from Boston-based obesity medicine physician, scientist, educator and policy maker Fatima Cody Stanford, MD in the media and on podcasts, but she also regularly shares insight on Instagram.

She’s who people turn to when the GLP-1 conversation starts to feel a little too glossy. Dr. Stanford talks openly about the realities that don’t always make it into viral posts, such as how unpredictable insurance coverage can be, why cost remains such a major barrier and what happens when people have to stop these medications.

She also stresses that GLP-1s aren’t a quick fix or a one-size-fits-all solution, and that treating obesity as a chronic condition means thinking long term.
