*For many people on GLP-1 weight-loss medications, quieting food noise has come with an unexpected trade-off: a full-blown fragrance obsession.
Comedian Todd Masterson, who goes by @GayFatFriend on Instagram and TikTok, was about three months into taking Zepbound when a single whiff of a Le Labo scent stopped him in his tracks. “It was like that trope in movies where someone takes a hit of a drug and then they flash cut to their pupil dilating and then flash cut to them flying through an electric tunnel,” he told HuffPost. “Like, it literally hit a nerve in my sinuses and it tattooed itself on my brain.” Fourteen months later, his bottle count has climbed to nearly 100.
Former fashion model Samantha King had a different but equally striking experience after starting Mounjaro nine months ago. Scents that previously triggered nausea had undergone a complete reversal. “GLP-1s didn’t make me fall in love with perfume, they changed how my body listens to it,” King explained. Both King and Masterson share a preference for gourmand, vanilla-forward scents.
Fatima Cody Stanford, an obesity medicine physician and associate professor at Harvard Medical School, says patients frequently describe a heightened sensitivity to smell after starting GLP-1 medications.

“Anecdotally, I have had patients report that their sense of smell feels ‘stronger’ or that certain scents are more noticeable after starting GLP-1 medications,” said Stanford.
“If food becomes less stimulating, other sensory experiences, like fragrance, may feel more salient or rewarding,” Stanford added.
Psychologist Valentina Parma of the Monell Chemical Senses Center offered a complementary explanation: “When food loses its pleasurable pull, other sensory sources – for instance, music, texture, scent – may fill that hedonic gap.”
Not every user leans into the shift. Some report being suddenly repulsed by scents they once loved – a sensory reversal that doctors compare to the smell aversions commonly experienced during pregnancy.
