Odd Lots (Bloomberg finance podcast) had an episode back in June or something interviewing a food design consultant, and their focus groups came back very strongly in favor of healthier meal compositions. Agreed though, it's hard to know things :) Hopefully some real studies on this will be done soon.
Did the consultant describe the change in focus group results or just the latest ones?
I was under the impression that consumers have been asking for healthier food compositions for decades, probably since the 70s or 80s when all the FUD around fat started. Maybe GLP1 agonists bring their buying choices more inline with the focus group results which would be an interesting phenomenon.
Industry led focus group is not a legitimate source.
