A professor at Cornell University’s Food and Brand Lab found that we don’t eat more because the food is good or we’re hungry, we do it because it’s visible and convenient. Brian Wansink says you’ll eat more if you dine family style — which means having serving bowls on the table, not fighting and arguing through dinner, if you eat directly from the bag or container, and if you ‘re served a large portion. In related news, Tyler Riewer of Lincoln, Nebraska, has been eating the same food with each meal for the past 30 days to fulfil a promise. Unfortunately for him the food is Spam. Hopefully he’s taking Professor Wansink’s advice and not serving it family style, not serving himself large portions, and lord help us, not eating right from the can.
