Most patients have heard of GLP-1 medications, but a new survey reveals significant gaps in how they work and realistic weight-loss expectations. Ads are outpacing doctors as the go-to information source — even though patients say they'd prefer clinical guidance. A surprising bonus finding: GLP-1 users may be sparking healthier habits across their entire households.
Nearly all patients surveyed (98%) had heard of GLP-1 medications, and most correctly identified their use for obesity and diabetes. But a new small study out of Philadelphia reveals that awareness doesn't equal understanding — many patients hold unrealistic weight-loss expectations and are getting their information from commercials rather than clinicians.
The survey of 52 adults at a North Philadelphia health system serving medically underserved patients found that by the one-year mark, over a third expected to lose 50–75 lbs on GLP-1s. Meanwhile, 73% cited ads as their primary info source, compared to 63% who turned to healthcare professionals. Despite this, 87% said they'd prefer to hear from a clinician.
A standout exploratory finding: among GLP-1 users living with other adults, most reported that their drug use prompted household members to rethink eating habits and physical activity — and some even reported weight loss in other family members.

Why it matters: With GLP-1 prescriptions surging, this study highlights a critical education gap — especially in underserved communities. Clinicians have a real opportunity to set realistic expectations and reclaim their role as the trusted source of health information.
