Almost every family has someone who does it. You ask them to cook dinner for four people, but the table ends up looking like a feast for ten. There are multiple side dishes, extra desserts, and enough leftovers to fill the refrigerator. Some people joke that these cooks "never learned portion sizes." Psychology suggests there may be a deeper explanation. For many people, preparing abundant food isn't simply about avoiding empty plates. It can reflect care, hospitality, family traditions, and a desire to make others feel comfortable and welcomed.
That doesn't mean everyone who cooks extra food is motivated by the same reasons. Some enjoy leftovers, others misjudge portions, and some simply love cooking. Still, psychological research offers several explanations for why abundance at the dinner table often carries emotional meaning.
