We’ve all been there: we order a delicious meal and we’re presented with a massive pile of food, much more than we know we should eat. “Oh, I’ll only eat half and will take home the rest for tomorrow,” we tell ourselves. The next thing we know, we look down at our plate and the entire meal is gone. We ate the entire thing and we feel stuffed. Overstuffed. And we still have to figure out what we’re going to eat for tomorrow.
1) Subjects were invited to a sit-down family-style dinner where pasta was offered in either a large-sized bowl or a medium-sized bowl. Those who took pasta from the large bowl ended up serving themselves 77% more pasta and eating 71% more pasta than those with the medium bowl. (2)
3) Subjects were invited to a soup-only lunch at a restaurant. Half of the subjects were given secretly rigged, self-refilling bowls of soup and the other half were given normal bowls. Those with the self-refilling bowls ate 73% more soup and 113 more calories than those with a normal bowl. (4)
