Small appetites, big consequences: what the rise of GLP-1s means for retail and hospitality
Every so often, a consumer shift comes along that genuinely changes how people eat, drink and shop. GLP-1 weight loss medications are one of them. New Worldpanel data shows the drugs wiped £780m off Britain’s grocery spend in the year to February 2026, with nearly two million British adults now taking them. The proportion of households with a GLP-1 user has almost tripled in two years, and the rise of weight loss medications is having one of the most profound impacts on consumer behaviour in years, if not decades.
Retail: fewer crisps, fuller pharmacies
The impact on the sector is stark. Households with a GLP-1 user spend £418 less a year on take-home food and drink. Three quarters of users are cutting back on chocolate and 72% on crisps, while confectionery spend drops 18 percentage points in the year after adoption. Over half report fewer cravings and the welcome silencing of ‘food noise’.
But what some retailers are losing in food and drink sales, they are attempting to make up for by selling the actual treatments themselves. Boots.com sales jumped 18.3% on the back of weight loss treatments. Asda Online Doctor’s monthly sales have grown from under £5m to around £30m in a year, and Tesco and Morrisons have launched their own services. And in a detail I enjoy more than I should, the drugs’ dry mouth side effect has driven a 20-point uplift in mouthwash spend and a 24-point bump in chewing gum. Every cloud.
Hospitality: the shrinking appetite economy
Hospitality should be watching just as closely. When appetite shrinks, so can covers, courses and rounds. More than one in ten users say they can no longer enjoy their favourite food and drink, and the treat occasion that underpins so much casual dining and snacking is being rewritten.
With pill formats expected within the year, adoption will only accelerate. The clever operators will identify the parallels between this and the low-and-no alcohol shift. This isn’t a threat to be waited out, but the creation of a whole new consumer segment that needs to be catered for with smaller plates, trade-up options, a doubling down on quality (over quantity) and menus built to flex.
What this means for brands and their PR
- First, own the commentary. Media are hungry for informed voices on GLP-1s, and the brands speaking credibly now will shape how the story is told in their category.
- Second, bring evidence. Sales data, consumer research and credentialled experts beat speculation every time. This is a health story as much as a retail and hospitality one, and it needs handling responsibly, which usually means a qualified third party alongside your founder or commercial lead.
- Third, be honest. If your category is exposed, say so, then talk about how you are adapting through portion innovation, reformulation or repositioning.
GLP-1s are not a fad to be ridden out. They are a once-in-a-generation change in consumer behaviour, and the brands that find their voice early will be the ones that consumers, and journalists, listen to.
