How GLP-1 Is Rewriting Eating, Cooking and Shopping
Overview
GLP-1 medications are growing fast in presence and cultural visibility. Their impact on food behaviour, cooking and shopping is real, measurable and already underway. Our self-funded research, combining quantitative data from 1,002 nationally representative shoppers (December 2025) with nine depth interviews and in-store shop walks (January/February 2026), produces a clear picture: GLP-1 users are not one type of person, there is not one GLP-1 diet and there will not be one winning brand strategy to meet their needs.
What we can say with confidence is that this group is younger, more affluent, more anxious, more planned in their shopping and more engaged with nutrition. The behavioural changes they are making have real potential to ripple outward, pointing to opportunities for brands and categories well beyond the GLP-1 user base itself.
This article captures those early signals. The bigger question that every client we have spoken to on this topic asks “is how sticky are these changes and what determines whether they last?”. This will be the subject of a follow-up article where we apply our Six S behavioural change model developed in 2021 to the GLP-1 evidence in full. Watch this space.
GLP-1 is not a single story and GLP-1 users are not a single type of shopper. People arrive at these medications with different mindsets, different relationships with food and different intentions. What we can do now is capture the early signals that consistently emerge across our quantitative and qualitative evidence and map what they mean for brands, categories and retailers.
Who Is the GLP-1 User?
GLP-1 is important but not yet a mass market shift. Currently 6% of shoppers are using these medications (one third via the NHS), with a further 9% lapsed users and an additional 13% expressing interest. That creates a potential universe approaching one in four, not a niche to ignore.
Demographically, the profile is striking. GLP-1 users are younger (71% aged 25–44), gender neutral, predominantly ABC1, more likely to have children and they carry a significantly higher mental and physical load than the general shopper population: 41% report feeling anxious vs 31% of all shoppers, and 45% have a disability vs 33%.
This is a high-value, behaviourally influential group. Behavioural changes that start here have a track record of pointing to wider opportunities.
Different Mindsets, Different Food Relationships, Different Intentions
There is no single GLP-1 diet, and there will not be one winning strategy for brands or categories. Whilst most users (52%) start with a clear, goal in mind, we do know that everyone will approach the medication and food they consume in fundamentally different ways. This is a personal journey.
Tactical Dosing: Switching usage on and off to fit moments in their lifestyle.
Maintenance: Using intermittently to keep weight or health stable.
Long-term commitment: Planning to use for the foreseeable future (29% of users).
Achieved through, for example....
Meal skipping: A new feeling of satiety that becomes a success in itself - eating becomes more task-like, appetite more binary.
Reprogramming: A more mindful, educated approach to eating as the foundation for a lasting healthier lifestyle.
Lightbulb moment: A portion size reality check, with no broader lifestyle change intended.
The Biggest Shift: From ‘Food Noise’ to Intentional Eating
The most consistent finding across our research is what users describe as a biological and psychological opt-out from impulsive cravings. Hunger becomes more binary: you are either hungry or you are not, with the constant background noise of craving, grazing and food-led distraction simply switching off.
The data reflects this clearly:
64% of current GLP-1 users report a reduction in appetite
39% say smaller portions of regular meals appeal
25% say breakfast is the most affected meal, more so than any other, with many delaying their first eating moment until later in the day
16% say all meals are affected, with eating becoming almost a task in itself
This shift is not simply about eating less. It is about eating more deliberately. When fewer eating moments occur, each one carries greater weight. The logic users consistently articulate is: when you can eat less overall, every mouthful must count.
Why this matters: Winning may depend less on persuading people in the moment and more on being the product they feel is genuinely ‘worth it’ when occasions are fewer and expectations are higher.
Calibration, Not Substitution
A crucial nuance: for most users this is not about radical diet replacement. It is better described as recalibration. Users still want familiar foods and familiar flavours. What changes is the quantity, the format and the intention with which those foods are consumed.
The journey tends to follow a consistent arc. Early on, certain foods are cut out, often prompted by digestive discomfort. Constipation (33% of current users), nausea (25%), diarrhoea (28%) and bloating (15%) are widely experienced. These are not merely inconvenient; they actively incentivise a move towards balanced, nutrient-rich diets. Someone who felt unwell after eating rich food or crisps does not simply decide to avoid them, they develop an aversion, rapidly and viscerally.
Longer term the focus shifts to adding in: protein, fibre, nourishment and balance. Health-forward does not mean joyless. GLP-1 users still want taste and pleasure. Indulgence has not disappeared, it has been recalibrated.
What consistently appeals to GLP-1 users:
Smaller portions of familiar, comforting foods
Snackable, flexible formats that work across occasions
Foods that are satiating, but not through sheer volume
High protein and fibre-rich options that deliver genuine nourishment
Nutrient-dense alternatives to ultra-processed foods
Why this matters: Think familiarity plus manageability: portionability, lighter formats and clear nutritional reassurance rather than assuming this consumer wants extreme diet cues. Overt GLP-1 labelling on-pack is meeting a sceptical reception: many users do not want that visibility in their basket or on their kitchen shelf.
Occasions Are Reshaping: Breakfast and Snacking Under Pressure
Breakfast has emerged as the meal most likely to be ‘skipped’ or significantly delayed. Appetite simply does not arrive in the morning for many users and the day’s first eating occasion is pushed back, sometimes by several hours.
Snacking is more complex. For some users it vanishes entirely as the snack noise ceases without effort or aversion. For others it evolves into something more purposeful: smaller, more intentional eating moments that function less like snacks and more like mini-meals. It is mindless grazing that disappears, not smaller eating moments per se.
These shifts all point in the same direction: fewer eating moments, but higher expectations out of each one.
Why this matters: If your category relies on habitual morning moments or impulse grab-and-graze behaviour, you may face reduced frequency, but not necessarily outright rejection. Conversely, if your product is nutritionally dense, it may be consumed more intentionally and in ways that justify a higher price per portion.
Nutrition Priorities Intensify, But This Is Not Just a GLP-1 Story
GLP-1 users significantly over-index on interest in high-protein products (52% vs 32% of non-users), fibre-rich foods (35% vs 24%) and nutrient-dense alternatives (34% vs 24%). Protein has moved from a fitness niche into a daily priority for this group, with users actively seeking convenient ways to hit their targets.
Interest in cleaner, less processed ingredients is not unique to GLP-1 users it’s a broader shopper trend. What GLP-1 does is amplify and accelerate it. For users eating less overall, the nutritional quality of every mouthful takes on greater significance. Food that merely fills is no longer sufficient. Food that actively nourishes is the new standard.
One particularly striking category finding: GLP-1 users are twice as likely to be increasing their frozen food purchasing compared to non-users (38% vs 19%). This reflects a broader shift toward planned, portion-controlled cooking and represents a significant opportunity for frozen food brands positioned around nutrition, flexibility and value.
Why this matters: Better-for-you propositions already rising in the mainstream are likely to accelerate in relevance for this group. The challenge is to deliver them without making people feel labelled or exposed. This is a real headwind for product launches that explicitly call out GLP-1 on-pack.
Shopping Shifts: Less Browsing, More Lists, More Online
When food noise reduces, shopping becomes more deliberate. The data here is striking in its scale:
84% of GLP-1 users report shopping online vs 50% of non-users
75% create shopping lists vs 64% of non-users
64% use meal kit subscriptions vs just 22% of non-users
Yes, this group skews younger and that influences channel behaviour. But the scale of difference between GLP-1 users and non-users signals something beyond a demographic effect. These shoppers have, in effect, opted out of the dopamine reward loop that drives impulse purchasing. Fewer missions, higher intention is the defining pattern.
Store visits are quicker, more directed and less exploratory. Browsing declines. Impulse-led category visits reduce. Getting into someone’s basket increasingly means getting onto their list before they leave home.
Meal kit services are playing a growing role, valued for taking the guesswork out of eating well: pre-portioned, nutritionally considered meals that still allow the satisfaction of cooking. Online grocery is similarly valued for the control it provides - searchability by nutrient, no unplanned temptations, a predictable basket.
Why this matters: If impulse weakens, pre-store wins matter more. Being compelling enough to get onto the shopping list, findable by nutrient or mission online, and showing up in the right search and filter pathways are becoming more important competitive battlegrounds than the end of an aisle.
Cooking Doesn’t Disappear, It Reignites
One of the more counterintuitive findings: GLP-1 users are not defaulting to convenience. Many report greater engagement with scratch cooking, motivated by the desire for control, ingredient transparency and measurable nutrition.
Slow cooker usage among GLP-1 users averages 2.73 sessions per week versus 1.23 among non-users and 45% cite health as the primary motivator, compared with 29% of non-users. This is not occasional batch cooking; it reflects a genuine shift toward planned, health-led meal preparation embedded into weekly routine.
The GLP-1 cooking style is characterised by planning ahead, measuring portions, preparing in advance and choosing formats that are there when needed without waste. The ‘GLP-1 fridge’, a concept emerging organically in online communities, is stocked with intentionality: protein shots, portioned snacks, prepped meals, measured ingredients.
Convenience still has a role, but it must work harder. Ready meals are not dismissed, but they need to justify themselves nutritionally. Convenience that feels fresh, controllable and not overly processed will outperform pure shortcut convenience.
Why this matters: Cooking continues, but new habits are shifting toward simpler, more sustainable routines. The opportunity is in supporting that journey: ingredients that are easy to use well, formats that aid portion control, and products that make nutritionally confident cooking feel achievable rather than effortful.
So, What Should Brands and Retailers Do Now?
These are early signals, not final answers. But several practical directions are emerging clearly enough to act on:
Design for fewer, more meaningful occasions: Portionable formats, little-and-often solutions, lighter-feeling options that deliver genuine satisfaction in smaller quantities
Make nutrition feel effortless: Help shoppers hit protein and fibre goals without turning eating into a task. The goal is nourishment that tastes good, not dietary compliance that feels like admin
Win pre-store: Clearer online visibility, stronger mission and filter cues, simpler decision shortcuts. If the list is made at home, the battle starts before the store
Be careful with overt GLP-1 labelling: Many shoppers actively do not want that association visible in their basket, on their shelf or in their home. The language of nourishment, protein and real ingredients travels further
Prioritise taste and texture: Fewer eating moments makes each one more significant, not less. Satisfaction, pleasure and genuine enjoyment become more important, not less
Strengthen emotional connections: In a world of more deliberate, purposeful eating decisions, emotional connections need to be re-shaped to resonate with a more intentional consumer. Brands relying on automatic, habitual selection face a more challenging environment
The Big Question: The Butterfly Effect of GLP-1
GLP-1 is not the only story, it is shining a spotlight on and accelerating trends already underway. More intentional eating, portion recalibration, less processed food, planned shopping, protein-first nutrition: none of these are new, but all are being amplified by GLP-1 adoption.
GLP-1 users also live within households. Their shifts are visible to partners, children and friends. This means behaviour changes for the whole household, not just the individual on medication. The ripples extend well beyond the 6% currently using.
But how strong are those ripples, and how long do they last? The stickiness question will ultimately determine the commercial significance of this shift. Does a new eating pattern survive when the medication stops? Does a new shopping routine persist when the biological prompt is withdrawn? Does a new identity as a mindful, intentional eater outlast the jab?
We already have some clear views on this, created from applying Shoppercentric’s Six S behavioural change model to the GLP-1 evidence. The model, originally developed and validated during the Covid-19 pandemic, provides a rigorous framework for distinguishing changes that are deeply imprinted from those likely to revert. Applied to GLP-1, it produces important and perhaps surprising conclusions about who will change lastingly, who will not, and why.

Shocks, Switches and Stickiness: Applying the Six S Model to GLP-1
Our follow-up article will take these findings and interrogate them through our Six S behavioural change model. We will examine which GLP-1-driven changes are truly sticky and which are likely to revert, what that means for brands and categories planning ahead, and how to use the model as a practical lens for understanding shopper behaviour in a world of growing GLP-1 influence.

The opportunity now is not to overreact, but to prepare. Understanding the direction of travel and which behaviours are most likely to persist. This gives brands and retailers time to adapt before change becomes the new normal.
