New research report

The Protein Halo

Are shoppers buying the nutrient, or the idea of it?

Protein is the hottest claim on the snack shelf. We ran 150 AI-moderated video interviews in shoppers’ own kitchens to find out what the claim really does, and what brands should do about it.

What we found

72% say protein makes their chosen product healthier, unprompted.

28% say a high-protein product can still be junk.

6% vs. 39% would buy without the protein: shoppers who know the grams vs. those who misjudge them.

55% vs. 41%: taste beats protein as a reason to buy again.

Inside the report

  • The three bands of protein shoppers, from “just the nutrient” to “the idea of it”

  • Why protein’s real job in the kitchen is fullness, not muscle

  • Owned vs. rented halos, and why knowing the grams decides whether a claim lasts

  • Four questions every protein brand should ask, and what to do about each

How we did it

Earlier studies used fictional products or surveys. We asked about a protein product each shopper chose, paid for and keeps at home. Then they photographed the label and read it aloud.


Who it’s for

  • Brand and innovation leads launching or relaunching a protein line

  • Packaging, claims and R&D teams deciding how to call out the grams

  • Consumer insights leads finding out which protein shoppers they have
