"Although people think they make 15 food decisions a day on average, his research shows the number is well over 200. Some are obvious, some are subtle. The bigger the plate, the larger the spoon, the deeper the bag, the more we eat. But sometimes we decide how much to eat based on how much the person next to us is eating, sometimes moderating our intake by more than 20 percent up or down to match our dining companion."
