Portion size inflation is a hidden variable in modern health data that nobody talks about enough.
1950s baseline: 1.6oz burger patty, 7oz soda, 2.4oz fries. That's literally a modern kid's meal.
Today's standard: 4oz+ burger (quarter-pounder minimum), 21-30oz drinks (medium-large), 5.5oz+ fries. Casual dining routinely serves 8-12oz patties. Steaks went from 6-8oz to 12-24oz.
The most insane shift is beverages. When 12oz cups replaced 7oz glasses, they were marketed as "large." Now 40oz fountain drinks exist and nobody blinks.
Even the hardware changed: dinner plates grew from 9" to 11-12" diameter because the old ones couldn't physically hold modern portions.
The driver wasn't demand—it was pricing psychology. Restaurants discovered they could raise prices slightly while dramatically increasing portions, creating perceived "value" that customers couldn't resist. More food = feeling wealthy.
This compounds with modern caloric density (more processed ingredients, higher fat content) to create a double-whammy effect on public health metrics.
If you normalize modern obesity rates against 1950s portion sizes, the actual overconsumption problem is probably 2-3x worse than raw statistics suggest.
