A structural change is working its way through food demand, and it does not come from a flavour trend or a viral video. It comes from a class of drugs. GLP-1 receptor agonists — the weight-loss injectables — suppress appetite, and a growing cohort of consumers now simply eat less food per sitting. When your customer’s stomach shrinks, every product assumption built on volume quietly breaks.
The retailers saw it first. In January 2026, Morrisons partnered with Applied Nutrition to launch 53 high-protein products across roughly 400 UK stores, including a “Small & Balanced” range engineered to sit at 325 kcal or less while still hitting high-protein and source-of-fibre claims. Co-op’s “Good Fuel” mini-meals arrived in 250g formats built around protein, fibre and a portion of five-a-day. The brief these products answer is new, and it is the inverse of everything FMCG optimised for over the last thirty years.
1The brief flips: from more to denser
For decades, value engineering in food meant adding perceived value — bigger portions, more indulgence, sharing formats, the upsell. The GLP-1 consumer inverts it. They cannot eat the bigger portion, and they don’t want it. What they need is maximum nutrition inside a much smaller envelope: enough protein to preserve muscle while they lose weight, enough fibre for satiety and gut health, meaningful micronutrients — all delivered in a few hundred calories they can actually finish.
That is a genuinely harder formulation problem than making food bigger and cheaper. Protein and fibre are the two most technically awkward things to pack into a small, palatable portion: protein can turn chalky or rubbery, fibre can turn gritty or cause off-textures, and both fight you on flavour and mouthfeel. Designing a 325-kcal meal that delivers 20-plus grams of good protein and still tastes like something you’d choose is real food technology, not a marketing reskin.
For thirty years the brief was “more for less”. The new brief is “enough, in less” — and it is harder.
2Density is the metric that matters now
The right way to think about these products is not calories, but nutrient density — grams of protein and fibre per 100 kcal, not per portion. A product can be small and still be excellent if what’s inside the envelope is doing real work. That reframing is the whole game, so it is worth making tangible.
3The trap to avoid: dressed-up shrinkflation
There is a cynical version of this trend, and shoppers can smell it. If “smaller portion” simply means the same food in a littler pack at a similar price, that is shrinkflation wearing a wellness badge, and it will be punished. The credible version earns the smaller size by genuinely re-engineering what’s inside — more protein, more fibre, better micronutrients — so the customer gets more nutrition, not less food for the same money. The difference between the two is entirely in the formulation, which is exactly where a food technologist earns their keep.
4Why this is an opportunity, especially in India
Most of the visible action so far is in UK and US retail. India is earlier in the GLP-1 curve, but the direction is the same, and the domestic product landscape is wide open — high-protein, portion-controlled Indian formats that respect real cuisine rather than importing bland “diet food” are barely being made. Indian food is, in places, already well-suited to this: pulse-and-grain combinations are naturally protein-and-fibre dense. The opportunity is to design for the shrinking appetite deliberately, with the nutrition front-loaded, rather than waiting for the trend to arrive fully formed. The consumer who eats half as much will reward whoever makes that half count.
