ppl keep blaming this, but this is contradicted by shrinkflation, yet people still are getting fatter than ever. There is nothing to stop someone from buying more food to offset smaller portions.

Shrinkflation is typically a retail issue, where pricing per unit is a massive psychological factor and competition is fierce and immediate (literally the next shelf). For restaurants it's much easier to just raise prices, or to bulk up plates with cheap stuff like bread.
