GLP-1 drugs change food habits: how SlimrChat saw the food revolution coming
Peter Paumgardhen | Last update: 1st July 2025
There’s been a quiet shift in what we eat and how much. At SlimrChat, many of you have been discussing this for months: the late-night snacks you no longer crave, the fast food that just doesn’t satisfy you, and the surprising urge to grab an apple instead of crisps. Now it’s not just talk. New academic research and financial headlines are catching up to what our community has been experiencing. GLP-1 weight loss drugs, such as Wegovy and Mounjaro, are reshaping food habits in real life, not just on the scale.
TL;DR
- SlimrChat users reported notable appetite and behaviour changes before many others picked up on the trend.
- Cravings dropped, portion sizes shrank, and healthier habits quietly emerged across our forums.
- A new academic study now confirms these patterns, and big brands are feeling the impact.
- The food industry is catching up to what SlimrChatters have been discussing for some time: GLP-1 drugs can change food habits.
SlimrChatters notice a shift in eating habits
While the media is now beginning to label this change a “food revolution”, SlimrChatters were among the first to openly share how their eating habits were evolving. Many of us noticed:
- Feeling full more quickly
- Emotional eating is becoming easier to manage
- Reduced cravings for high-fat or sugary foods
- Water is becoming a preferred drink
- A natural shift toward protein, fibre and whole foods
One SlimrChat user shared:
“I used to live on take-aways. Now I can’t even finish a small portion, and weirdly, I don’t miss it.”
Another added:
“I crave fruit. Actual fruit. That’s a sentence I never thought I’d say.”
These weren’t isolated experiences. Across the SlimrChat Forums, dozens of threads echoed the same thing: weight loss wasn’t just physical. It was behavioural. People weren’t forcing themselves to choose better food. They just were.
The No-Hunger Games: research backs it up
Now, a major academic study has confirmed what many SlimrChatters were already describing. In “The No-Hunger Games: How GLP-1 Medication Adoption is Changing Consumer Food Demand”, researchers from Johns Hopkins and Cornell analysed real grocery and restaurant data. They found that users of weight loss jabs really do shop, cook and eat differently.
Key findings:
- Grocery spending dropped by 5.5% in GLP-1 households, and by 8.6% in wealthier households
- The biggest drops were in high-calorie snacks and processed foods like crisps and pastries
- Fast food visits fell by 8.6%, especially among lower-income users
- Portion sizes and shopping baskets shrank
- The changes persisted for at least 12 months, even as they lessened over time

The changes SlimrChatters have been describing are now backed by hard data.
The big food wake-up call
Financial analysts and food giants are taking notice.
McDonald’s was downgraded by Redburn Atlantic, citing GLP-1 drugs as a risk to future sales (reported by CBS News).
PepsiCo’s CEO, Ramon Laguarta, told investors that GLP-1 users are consuming smaller portions of fizzy drinks and are leaning towards protein, fibre, and hydration products.
In the UK, grocery sales volumes fell for the first time this year. According to The Times, Kantar analysts believe the rise in GLP-1 users could be partly responsible (June 2025). Fraser McKevitt of Kantar told The Times:
“Four in 100 UK households now include at least one GLP-1 user, nearly double from last year.”
He added:
“Four in five users say they plan to eat fewer chocolates and crisps, and nearly three-quarters say they’ll cut back on biscuits.”
Even alcohol brands are reacting. Fund manager Terry Smith recently sold his shares in Diageo, citing worries that GLP-1 weight loss drugs are reducing alcohol consumption (Financial Times).
From supersize to slimdown: where do we go from here?
At SlimrChat, we’ve always believed that weight loss isn’t just about the scale. It’s about mindset, cravings and the habits we build. And GLP-1 weight loss treatments are reshaping those habits in unexpected ways.
This isn’t just a diet. It’s a rewiring.
And that rewiring is creating a ripple effect, not only for individuals but across industries. Supermarkets, fast-food chains, and snack makers will need to adapt.
As the world scrambles to adjust, it’s clear that the experiences shared by SlimrChatters were early signs of a broader transformation.
