After protein: the smaller plate and dairy's fibre gap

When we first wrote about GLP-1 medication in March, the open question was whether people eating less would choose dairy protein. Seven months on, the shelf says broadly yes, and protein has become the expected standard rather than the reason to buy. The more useful change since then is portion size. People on the medication buy fewer packs and order smaller plates, and what they look for on the front of a pack is moving on from protein to fibre. Fibre is the first claim in this cycle that dairy cannot make from milk alone.

The scale is now clear enough to plan around. Worldpanel by Numerator estimated in June that 6.3% of GB households had a GLP-1 user, about 1.9 million adults, and that those households bought 299 million fewer packs across its analysis period. Lumina Intelligence, reported on 5 October, puts current users at 6.1% of UK adults. The two estimates measure different things and we found no official UK count, but both show use roughly tripling since 2024.

The figure that matters most for range planning sits further down the same Worldpanel survey. Of the people who stopped using the medication in 2026, 41% said it was too expensive. Shoppers move on and off it. We looked for UK data on what people buy after they stop and did not find any published. Until that data exists, the safer design brief is anyone who now eats a smaller meal, including the shoppers over 65 who drove cottage cheese growth in our June analysis, rather than medication users alone.
