Another source of shrinkflation is changing ingredients. Something that used to be 50% water is now 75% water as an example. Another is changing from olive oil to canola or palm or, and things like that.
Now they've started including frozen sauce packets as well. I've weighed some of these and found, for example, a 2 lb box of chicken wings that comes with more than half a pound of buffalo sauce. The net weight stays the same (2 lb) but if you weigh the chicken you're getting less than 1.5 lb of meat! The rest is all sauce!
But then again if there is no health impact (like with Trans fats) then is there any incentive for the regulators to change this?
Has the FDA ever done any work to protect consumers from sketchy marketing/labeling of products?
(I asked ChatGPT and it gave me a few bits. Apparently the term "Healthy" is regulated. And serving sizes are another that seem to be regulated. Maybe there is an angle within there that would make sense.)
