\u201cIt 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,\u201d he told HuffPost. \u201cLike, it literally hit a nerve in my sinuses and it tattooed itself on my brain.\u201d<\/p>\n
That was just the start of it. Fourteen months after starting Zepbound \u2015 an injectable GLP-1 medication<\/a> for weight loss \u2015 Masterson has lost almost 80 pounds and gained a full-on fragrance obsession. His collection \u2015 heavy on intense florals and vanilla scents \u2015 is nearing 100 bottles. <\/p>\n \u201cIt\u2019s not a hunger craving, but I reapply several different scents throughout the day,\u201d he said. \u201cI love to layer. My tastes change daily. I like bright stuff in the morning and gourmand stuff before bed.\u201d<\/p>\n Samantha King, a former fashion model from Northern Tasmania, noticed a different kind of sensory shift after starting Mounjaro nine months ago: Fragrances that once turned her stomach suddenly felt wearable, even irresistible in some cases.<\/p>\n \u201cSo rather than feeling \u2018hungry\u2019 for scents, it\u2019s more that my tolerance and perception have shifted,\u201d said King, who shares her GLP-1 experiences on YouTube<\/a>. \u201cGLP-1s didn\u2019t make me fall in love with perfume, they changed how my body listens to it.\u201d<\/p>\n Like Masterson, she gravitates toward foodie-forward, vanilla-based scents. That\u2019s not uncommon. As The Guardian reported,<\/a> perfume companies are in the midst of a gourmand boom, fueled by consumer appetite for sweet, dessert-like notes such as vanilla, pistachio and caramel \u2014 a trend one global beauty analyst linked directly to the rise of GLP-1 weight-loss drugs.<\/p>\n Catherine Falls Commercial via Getty Images<\/p>\n “It’s not universal, but the theme is increased sensory awareness rather than a complete change in smell,” said Fatima Cody Stanford, an obesity medicine physician and associate professor of medicine and pediatrics and Harvard Medical School.<\/p>\n Doctors who prescribe GLP-1 drugs like Ozempic, Wegovy and Mounjaro to quiet \u201cfood noise\u201d<\/a> say they\u2019re hearing more patients describe unexpected changes in the way they experience scents, too.<\/p>\n \u201cAnecdotally, I have had patients report that their sense of smell feels \u2018stronger\u2019 or that certain scents are more noticeable after starting GLP-1 medications,\u201d said Fatima Cody Stanford<\/a>, an obesity medicine physician and associate professor of medicine and pediatrics at Harvard Medical School.<\/p>\n \u201cMost commonly, they describe heightened sensitivity to food smell \u2015 sometimes finding fried or heavy foods less appealing,\u201d Stanford said. A smaller number have mentioned becoming more aware of non-food scents as well, such as perfumes and household fragrances.<\/p>\n \u201cIt\u2019s not universal, but the theme is increased sensory awareness rather than a complete change in smell,\u201d she said. <\/p>\n On Reddit, there\u2019s no shortage of people<\/a> on GLP-1s <\/a>talking about their growing perfume collections and how they\u2019re firmly leaning into their scent obsession.<\/p>\n \u201cWearing these scents is about taking back a beautiful sensory experience without the guilt that always followed before,\u201d one woman wrote<\/a>. \u201cThe smell of dessert, which used to signify psychological defeat, now feels like a huge symbol of freedom.\u201d<\/p>\n Others report being repulsed by smells they once loved. Candles, certain perfumes are an \u201cimmediate ick,\u201d<\/a> in the same way pregnancy hormones flip the script on certain tastes and smells.<\/p>\n What exactly is going on? Stanford suspects it may be tied to a shift in sensory focus as GLP-1 users experience reduced food reward. Reduced food reward refers to a diminished sense of pleasure, satisfaction, or dopamine-driven \u201cliking\u201d and \u201cwanting\u201d associated with eating, often resulting in a lower motivation to consume food.<\/p>\n \u201cIf food becomes less stimulating, other sensory experiences, like fragrance, may feel more salient or rewarding,\u201d Stanford said. <\/p>\n Kate Wieser via Getty Images<\/p>\n Large, controlled studies on the phenomenon still haven\u2019t been conducted, and more research is needed before scientists can draw firm conclusions on why GLP-1 users are gravitated toward the perfume counter. <\/p>\n As Valentina Parma<\/a>, a psychologist who studies human olfaction at the Monell Chemical Senses Center, put it: \u201cWhen food loses its pleasurable pull, other sensory sources \u2015 for instance, music, texture, scent \u2015 may fill that hedonic gap.\u201d<\/p>\n To get a bit more scientific, Parma explained that GLP-1 receptors are found in the mitral cells of the olfactory bulb \u2014 the brain region involved in processing smell \u2014 as well as in the hippocampus. Research suggests the local GLP-1 system within the olfactory bulb plays a role in odor-triggered insulin secretion and foraging behavior,<\/a> hinting at a deeper connection between smell, metabolism and appetite.<\/p>\n \u201cChanges in GLP-1 signaling could modulate how odors are processed centrally, in ways that are subtle but evident for some,\u201d she told HuffPost.<\/p>\n![\""It's](\"https:\/\/www.europesays.com\/us\/wp-content\/uploads\/2026\/05\/6a064cd61d00008d8aa13b67.jpeg\")
